5 Phase Two Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario January 2014 Unimin Canada Ltd. Pinchin File: EXECUTIVE SUMMARY Pinchin Environmental Ltd. ( Pinchin ) was retained by Unimin Canada Ltd. ( Client ) to complete a Phase Two Environmental Site Assessment ( Phase Two ESA ) for the property located at 288 and 420 Bayshore Drive in Midland, Ontario (hereafter referred to as the Site or Phase Two Property ). The Phase Two Property currently consists of vacant land; however, the west portion of the Phase Two Property was previously developed with six industrial buildings consisting of a single-storey building utilized as an office and warehouse/storage building; an eight-storey mill building; a six-storey dryer building; a two-storey building utilized as a change room, former lunchroom and lab; a single-storey maintenance shop; and a three-storey building utilized in the milling processes. This eastern portion of the Phase Two Property historically operated as an industrial property that included a coal dock and railway lines and sidings. The eastern portion of the Phase Two Property was converted into parkland by Unimin in approximately The Phase Two Property is located in an area of mixed land use, including residential, commercial, community, industrial and vacant land uses, where potable water is supplied to the Phase Two Property and surrounding properties by the Town of Midland. This Phase Two ESA was conducted at the request of the Client as a condition for the divestment of the Phase Two Property. A Record of Site Condition ( RSC ) submittal to the Ontario Ministry of Environment ( MOE ) is anticipated to be required as a condition for the redevelopment of the Phase Two Property to a more sensitive land use and as such, to facilitate an RSC application, the Phase Two ESA was conducted in accordance with the Province of Ontario s Ontario Regulation 153/04: Records of Site Condition Part XV.1 of the Act, which was last amended by Ontario Regulation 269/11 on October 31, 2011 ( O.Reg. 153/04 ). The objectives of this Phase Two ESA were to assess the soil and groundwater quality in relation to nine areas of potential environmental concern ( APECs ) and related potential contaminants of concern ( PCOCs ) identified in a Phase One ESA completed by Pinchin in accordance with O.Reg. 153/04. The Phase Two ESA was completed at the Phase Two Property by Pinchin between June 12 and July 3, 2013, as well as between December 4 and December 5, 2013 and included the advancement of 20 test-pits and 20 boreholes at the Phase Two Property. Of the 20 boreholes, 11 were completed as groundwater monitoring wells to facilitate the sampling and assessment of groundwater quality. The test-pits were advanced to maximum depths ranging from 1.8 to 4.6 metres below ground surface ( mbgs ) and boreholes were advanced to maximum depths ranging from 2.9 to 7.5 mbgs. Select soil samples were 2014 Pinchin Environmental Ltd. Page 1

6 Phase Two Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario January 2014 Unimin Canada Ltd. Pinchin File: collected from each of the test-pit and borehole locations and submitted for laboratory analysis of petroleum hydrocarbons ( PHCs ) fractions 1 through 4 ( F1-F4 ), volatile organic compounds ( VOCs ), polycyclic aromatic hydrocarbons ( PAHs ), polychlorinated biphenyls ( PCBs) and/or metals. In addition, groundwater samples were collected from the 11 newly-installed monitoring wells and submitted for laboratory analysis of PHCs (F1-F4), VOCs, PAHs, PCBs and/or metals. Based on site-specific information, the applicable regulatory standards for the Phase Two Property were determined to be the MOE Table 9 Standards for residential/parkland/ institutional/industrial/commercial/community land use and medium/fine-textured soil.

9 Phase Two Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario January 2014 Unimin Canada Ltd. Pinchin File: INTRODUCTION A Phase Two Environmental Site Assessment ( ESA ) is defined as an assessment of property conducted in accordance with the regulations by or under the supervision of a qualified person ( QP ) to determine the location and concentration of one or more contaminants in the land or water on, in or under the property. Under the Province of Ontario s Ontario Regulation 153/04: Records of Site Condition Part XV.1 of the Act, which was last amended by Ontario Regulation 269/11 on October 31, 2011 ( O.Reg. 153/04 ), the purpose of a Phase Two ESA is as follows: To determine the location and concentration of contaminants in the land or water on, in or under the Phase Two Property; To obtain information about environmental conditions in the land or water on, in or under the Phase Two Property necessary to undertake a risk assessment, in accordance with O.Reg. 153/04, with respect to one or more contaminants of concern; and To determine if applicable Site Condition Standards and standards specified in a risk assessment for contaminants on, in or under the Phase Two Property were met as of the certification date by developing an understanding of the geological and hydrogeological conditions at the Phase Two Property and conducting one or more rounds of field sampling for all contaminants associated with any area of potential environmental concern ( APEC ) identified in the Phase Two ESA sampling and analysis plan ( SAP ) and for any such contaminants identified during subsequent Phase Two ESA activities and analyses of environmental conditions at the Phase Two Property. This Phase Two ESA was conducted at the request of Unimin Canada Ltd. ( Client ) as a condition for the divestment of the property located at 288 and 420 Bayshore Drive in Midland, Ontario (hereafter referred to as the Site or Phase Two Property ). A Record of Site Condition ( RSC ) submittal to the Ontario Ministry of Environment ( MOE ) is anticipated to be required as a condition for the divestment and potential redevelopment of the Phase Two Property to a more sensitive land use and as such, to facilitate an RSC application, the Phase Two ESA was conducted in accordance with O.Reg. 153/04. The overall objectives of this Phase Two ESA were to assess the soil and groundwater quality in relation to APECs and related potential contaminants of concern ( PCOCs ) identified in a Phase One ESA completed by Pinchin, the findings of which were summarized in the report entitled Phase One Environmental Site Assessment, 288 and 420 Bayshore Drive, Midland, Ontario, completed by Pinchin for the Client and dated January 2014 ( Pinchin Phase One ESA Report ). The Phase Two ESA was conducted on the entire Phase One Property with no limitations, at specific APECs identified during the Phase One ESA Pinchin Environmental Ltd. Page 5

Pinchin File: Centroid UTM Co-ordinate Detail Source / Reference Information Legal Survey Easting Northing Zone 17T A legal survey showing the Phase Two Property is provided in Appendix A. 2.2 Property Ownership The entirety of the Phase Two Property is currently owned by Unimin Canada Ltd., with a business address of 637 The Queensway, Suite 13, Havelock, Ontario. 2.3 Current and Proposed Future Land Uses The Phase Two Property is presently vacant, but is utilized for industrial and parkland purposes and it is Pinchin s understanding that the Client intends to divest the property which will potentially be redeveloped with residential/parkland land uses. Given that the future land use is potentially changing to a more sensitive land use (i.e., residential/parkland), there will be a regulatory requirement that an RSC be filed as per Section of the Province of Ontario s Environmental Protection Act. 2.4 Applicable Site Condition Standards This Phase Two Property is currently an industrial and parkland property located within the Town of Midland and the proposed future land use is mixed-use residential/parkland. It is Pinchin s understanding that drinking water for the Phase Two Property and surrounding properties within 250 metres of the Phase Two Property is supplied by the Regional Municipality of Midland ( Region ). Source water is obtained by the Region from Georgian Bay. Bedrock was encountered between approximately 2.9 and 7.5 metres below ground surface ( mbgs ) and, as such, the Phase Two Property is not a shallow soil property as defined in Section 43.1 of O. Reg. 153/04 (i.e., greater than two thirds of the property was documented to consist of more than 2 meters of overburden). Ontario Regulation 153/04 (as amended) states that a site is classified as an environmentally sensitive area if the ph of the surface soil (less than 1.5 mbgs) is less than 5 or greater than 9, the ph of the subsurface soil (greater than 1.5 mbgs) is less than 5 or greater than 11, or if the Site is an area of natural significance or is adjacent to or contains land within 30 metres of an area of natural significance. Twenty representative soil samples collected from the boreholes advanced at the Site were submitted for ph analysis. The ph values measured in the submitted soil samples were within the limits for non-sensitive sites. The Phase Two Property is also not an area of natural significance and 2014 Pinchin Environmental Ltd. Page 8

13 Phase Two Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario January 2014 Unimin Canada Ltd. Pinchin File: it is not adjacent to, nor does it contain land within 30 metres of, an area of natural significance. As such, the Phase Two Property is not an environmentally sensitive area. However, the Phase Two Property is located within 30 metres of a natural surface water body. As discussed in Section 6.6, based on the results of grain size analysis completed on representative soil samples collected during the Phase Two ESA and the observed stratigraphy at the borehole and test pit locations at the Phase Two Property, it is Pinchin s opinion that over one-third of the overburden at the Phase Two Property is medium/finetextured as defined by O.Reg. 153/04. Therefore, the soil at the Phase Two Property has been considered medium/fine -textured for the purposes of establishing the applicable MOE Site Condition Standards. Based on the above, the appropriate Site Condition Standards for the Phase Two Property are: Table 9: Full Depth Generic Site Condition Standards for Use within 30 m of a Water Body in a Non-Potable Ground Water Condition, provided in the MOE Standards ( Table 9 Standards ) for: o o Medium/fine -textured soils; and Residential/parkland/institutional/industrial/commercial/community property use. As such, all analytical results have been compared to these MOE Table 9 Standards. 3.0 BACKGROUND INFORMATION 3.1 Physical Setting The Phase Two Property is located in the north/central portion of Midland, Ontario. Based on information obtained from the Ontario Base Map series, the Phase Two Property is situated at an elevation between approximately 177 and 182 metres above mean sea level ( mamsl ). There are no open water bodies or areas of natural significance located on-site. However, Midland Bay, Georgian Bay is adjacent to the north elevation of the Site and therefore within the area assessed by the Pinchin Phase Two ESA (the Phase Two study area ).

Pinchin File: Past Investigations Summary of Environmental Investigations Completed As part of the Pinchin Phase One ESA, the following reports were reviewed for the Phase Two Property: Report entitled Phase I Environmental Site Assessment Bayshore Drive, Midland, Ontario prepared by Pinchin for Unimin Canada, dated July 2012 (the Pinchin 288 Bayshore Drive 2012 Phase I ESA Report ); Report entitled Phase I Environmental Site Assessment Bayshore Drive, Midland, Ontario prepared by Pinchin for Unimin Canada, dated July 2012 (the Pinchin 420 Bayshore Drive 2012 Phase I ESA Report ); and Report entitled Phase One Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario prepared by Pinchin for Unimin Canada, dated January 2014 (the Pinchin 2014 Phase One ESA Report ). No other reports or letters were reviewed for the Phase Two Property or surrounding properties Pinchin Phase One ESA Summary In May to June 2013, Pinchin conducted a Phase One ESA at the property in support of the future filing of an RSC for the Phase Two Property. The Phase One ESA consisted of the Site visit, interviews with Site personnel, records review, evaluation of information, and preparation of a written report which was completed under the supervision of a QP. The Pinchin 2013 Phase One ESA Report was completed recently and in accordance with the requirements of O.Reg. 153/04. Therefore, the information provided within the report is considered adequate such that it can be relied upon for the purposes of this Phase Two ESA and future filing of an RSC. Based on information obtained during the Phase One ESA, a total of nine APECs and corresponding PCOCs were identified that could potentially affect the environmental condition of the subsurface media on, in or under the Phase Two Property. The PCOCs associated with each APEC were based on a review of the contaminating source areas and hazardous substances associated with the related activities. Each PCOC was APEC-specific and was determined based on several sources of information, including, but not limited to: Pinchin s experience with environmental contamination and hazardous substances; common industry practices for analysis of such contaminants and point sources; literature reviews of PCOCs and associated hazardous substances; and evaluations of contaminant mobility and susceptibility for migration in the subsurface. The following table presents the APECs and their associated PCOCs: 2014 Pinchin Environmental Ltd. Page 10

Pinchin File: APEC No. APEC PCOCs Media Potentially Impacted (Groundwater, Soil and/or Sediment) APEC 9 Midland Engine Works Company was present south of the Phase Two Property in PHCs VOCs Metals ph Soil and Groundwater The media of concern for the Phase Two ESA were soil and groundwater. Pinchin included the assessment of groundwater quality as part of the Phase Two ESA to determine whether former ASTs and USTs, former coal dock and ship loading located at the Phase Two Property (APECs 1 to 4) and potential subsurface contamination migrating from off the Phase Two Property (APECs 8 and 9) had impacted groundwater quality at the Phase Two Property. Pinchin did not conduct sediment sampling as part of this Phase Two ESA. For assessing the soil at the Phase Two Property for the presence of PCOCs, six test-pits and 20 boreholes were advanced at locations across the Phase Two Property for the purpose of collecting soil samples between June 12 and July 3, additional testpits were advanced at locations across the Phase Two Property for the purpose of collecting soil samples between December 4 and December 5, Select worst case soil samples collected from each of the boreholes were submitted to the analytical laboratory for analysis of the PCOCs. For assessing the groundwater at the Phase Two Property for the presence of PCOCs, groundwater monitoring wells were installed in 11 of the 20 boreholes completed at the Phase Two Property to permit the collection of groundwater samples. Groundwater samples were collected from each of the newly installed monitoring wells and submitted to the analytical laboratory for analysis of the PCOCs. 4.3 Conceptual Site Model A conceptual site model ( CSM ) is a three-dimensional representation of a property that conveys what is known or suspected about the physical and chemical nature of the property including contaminant sources and the transport and fate of those contaminants. The CSM provides the basis for understanding contaminant fate and transport issues and assessing potential remedial technologies at the property. A CSM was created during the Pinchin Phase One ESA to provide a detailed visualization of the APECs which could occur on, in, under, or affecting the Phase Two Property. The CSM of the Phase Two Property was derived from data available during the completion of the Phase One ESA and accepted principles of groundwater flow and contaminant transport. The CSM also presented the PCOCs, the locations and descriptions 2014 Pinchin Environmental Ltd. Page 17

22 Phase Two Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario January 2014 Unimin Canada Ltd. Pinchin File: of underground utilities, and available Site-specific hydrogeological information. Furthermore, the CSM illustrated the potential exposure pathways and receptors, which Pinchin had identified to exist at the Phase Two Property, based on the use of the MOE s O.Reg. 153/04 rationale document entitled Rationale for the Development of Soil and Ground Water Standards for Use at Contaminated Sites in Ontario, dated December 22, 2009, prepared by the Standards Development Branch of the MOE. The Phase Two Property is relatively flat with a slight slope to the north. The Phase Two Property is comprised of vacant land complete with a 9 m 2 shed on the central portion of the Phase Two Property. The properties surrounding the Phase Two Property are at an equivalent grade with an increase in elevation at the south. The Phase One ESA identified the properties to the south as being hydraulically upgradient, and the properties to the north as being hydraulically downgradient. This information was based on the presence of Midland Bay, Georgian Bay and the topography. The Phase One CSM noted that all surface water which lands on the property is anticipated to flow overland and drain into Midland Bay, Georgian Bay adjacent to the north elevation of the Phase Two Property. Underground utilities which service the Phase Two Property have all been removed during the demolition in Utility corridors are often preferential pathways for contaminant migration due to the coarse and sometimes frequently uncompacted nature of the surrounding fill material. However, based on the depth to groundwater at the Phase Two Property, the former utility corridors were expected to be dry and are not expected to affect contaminant distribution and transport in the event that shallow subsurface contaminants exist at/in these locations. The Pinchin Phase One ESA identified a total of nine APECs and corresponding PCOCs which could potentially affect the environmental condition of the subsurface media on, in or under the Phase Two Property. The PCOCs associated with each APEC were based on a review of the potentially contaminating source areas and hazardous substances associated with the related activities. Each PCOC was APEC-specific and was determined based on several sources of information, including but not limited to: Pinchin s experience with environmental contamination and hazardous substances; common industry standards for analysis of such contaminants and point sources; literature reviews of PCOCs and associated hazardous substances; and evaluations of contaminant mobility and susceptibility for migration in the subsurface. With respect to the Phase One CSM, Pinchin evaluated the potential exposure pathways and receptors that may be affected by the APECs. The exposure pathways and receptors which Pinchin has considered are as follows: 2014 Pinchin Environmental Ltd. Page 18

Human health through odours and inhalation; and Ecotoxicity to soil invertebrates. In considering the future development activities (i.e., digging, construction, etc.) at the Phase Two Property and intended use (i.e., mixed-use commercial/residential), the GW2, GW3 S1, S2, S3, S-IA, S-OA, S-Odour and S-GW3 pathways were considered applicable. The GW1 and S-GW1 pathways were not considered a concern as the Phase Two Property is supplied by municipal water. An updated evaluation of potential exposure pathways and receptors, based on the results of this Phase Two ESA, is discussed in Section An overview of the Phase Two Property and its proximity to the APECs is provided in Figure Deviations from Sampling and Analysis Plan No notable constraints or limitations with respect to the SAP were documented during the field activities, and as such Pinchin has conducted the Phase Two ESA in a manner generally consistent with the SAP provided in Appendix B Pinchin Environmental Ltd.

Pinchin File: Impediments Pinchin had full access to the Phase Two Property throughout the completion of the Phase Two ESA. 5.0 INVESTIGATION METHOD 5.1 General The Phase Two ESA field work was conducted in accordance with Pinchin s standard operating procedures ( SOPs ), which have been developed in accordance with the procedures and protocols provided in the MOE document entitled Guidance on Sampling and Analytical Methods for Use at Contaminated Sites in Ontario dated December 1996 and in O.Reg. 153/04. In addition, Pinchin s SOP for groundwater sampling using low-flow purging and sampling procedures is based upon the United States Environmental Protection Agency Region I document entitled Low Stress (Low Flow) Purging and Sampling Procedure for the Collection of Groundwater Samples from Monitoring Wells dated January 19, 2010 ( Low Flow Sampling Protocol ). 5.2 Drilling and Excavating Pinchin retained Morden Construction to excavate a total of six test-pits (TP01 through TP06) at the Phase Two Property. In addition, Pinchin retained Strata Drilling Group ( Strata ) to advance a total of 20 boreholes (BH01 through BH20) at the Phase Two Property. Drilling and excavating activities were completed between June 12 and 20, 2013 to investigate the potential presence of soil contaminants associated with the APECs identified in the Phase One ESA. 11 of the drilled boreholes (BH02, BH03, BH06, BH08, BH09, BH10, BH12, BH15, BH17, BH18 and BH20) were completed as monitoring wells in accordance with O.Reg. 903 for the purpose of monitoring hydrogeological conditions and groundwater quality on-site. The test-pits were excavated to a maximum depth of 4.6 mbgs using a John Deere 50 rubber-tired backhoe and the boreholes were drilled to a maximum depth of 7.5 mbgs using a Geoprobe 7822 DT drill rig. Upon completion of the drilling and monitoring well installations, Strata completed and filed appropriate Water Well Records with the MOE for the wells in accordance with O.Reg Pinchin returned to the Phase Two Property on December 4 and December 5, 2013 and retained Morden Construction to excavate a total of 14 test-pits (TP101 through TP114) at the Phase Two Property.

The locations of the test-pits, as well as the boreholes/monitoring wells are provided on Figure 3. The soil sample location depths and laboratory analyses are summarized in Table 1. A description of the subsurface stratigraphy encountered during the test pit drilling program is documented in the test pit/borehole logs included in Appendix C. Well completion details and elevation data are provided in Table 2 and on the borehole logs provided in Appendix C. 5.3 Soil Sampling Soil samples were collected in the test-pits at regular intervals of 0.5 m. Discrete soil samples were collected from the bucket of the backhoe/excavator and containerized in laboratory-supplied glass sampling jars. Subsurface soil conditions were logged on-site by Pinchin personnel at the time of the excavation work. Soil samples were collected in the boreholes at regular intervals of 0.61 m from within 10.1 centimetre ( cm ) outer diameter ( OD ) core barrel samplers outfitted with dedicated single-use plastic liners. Subsurface soil conditions were logged on-site by Pinchin personnel at the time of drilling. Discrete soil samples were collected from within the dedicated sample liners with dedicated and disposable Nitrile gloves and containerized in laboratory-supplied glass sampling jars. Following sample collection, the sample bottles were placed into dedicated coolers with ice for storage pending transport to AGAT. Formal chain of custody records were maintained between Pinchin and the staff at AGAT. Based on the soil samples recovered during the test pit/borehole drilling program, the soil stratigraphy at the drilling locations generally consists of sand and gravel, sand and/or silt fill, with occasional cobbles, brick, glass, coal and metal debris, to a maximum depth of 2014 Pinchin Environmental Ltd. Page 23

28 Phase Two Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario January 2014 Unimin Canada Ltd. Pinchin File: approximately 2.0 mbgs, followed by a sandy silt to silty clay unit that extended to the maximum investigation depth of approximately 7.5 mbgs. A detailed description of the subsurface stratigraphy encountered during the test pit/borehole drilling program is documented in the test pit/borehole logs included in Appendix C. 5.4 Field and Screening Measurements Soil samples were collected at each of the sampling intervals during the test pit/drilling activities and analyzed in the field for petroleum-derived vapour concentrations in soil headspace with an RKI Eagle CGI operated in methane elimination mode. The soil samples collected for field-screening purposes were placed in sealable plastic bags. The plastic bags were stored in a warm environment for a minimum of five minutes and agitated in order to release organic vapours within the soil pore space prior to analysis with the CGI. Based on a review of the operator s manual, the RKI Eagle CGI has an accuracy/precision of up to +/- 25 ppm, or +/- 5% of the reading (whichever is greater). The CGI was calibrated prior to field use by Pine Environmental ( Pine ) according to Pine s standard operating procedures. In addition, the CGI calibration was tested at the beginning of each day of test pit/drilling activities (beginning on the second day of test pit/ drilling) against a Spectra-provided hexane gas standard with a concentration of 400 ppm. The gas standard was stored in a gas cylinder and delivered to the CGI via a regulator valve. An in-field re-calibration of the CGI was conducted (using the gas standard in accordance with the operator s manual instructions) if the calibration check indicated that the CGI s calibration had drifted by more than +/- 10%. In general, the soil samples with the highest measured vapour concentrations (i.e., worst case ) from a given test pit/borehole were submitted for laboratory analysis. Sample depth and visual and olfactory observations were also used in conjunction with the vapour concentrations in making the final selection of worst case soil samples for laboratory analysis. 5.5 Groundwater Monitoring Well Installation Following soil sampling, Strata installed a groundwater monitoring well in boreholes BH02, BH03, BH06, BH08, BH09, BH10, BH12, BH15, BH17, BH18 and BH20, under the full-time monitoring of a Pinchin field representative. Each of the monitoring wells was 2014 Pinchin Environmental Ltd. Page 24

29 Phase Two Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario January 2014 Unimin Canada Ltd. Pinchin File: constructed with 51-millimetre (2-inch) inner diameter flush-threaded schedule 40 polyvinyl chloride ( PVC ) risers followed by a 3.1 m length of No. 10 slot PVC screen. Each well screen was sealed at the bottom using a threaded cap and each riser was sealed at the top with a lockable J-plug cap. Silica sand was placed around and above the screened interval to form a filter pack around the well screen. A layer of bentonite was placed above the silica sand and was extended to the ground surface. A protective flushmount cover was installed at the ground surface over each riser pipe and cemented in place. All monitoring wells were installed in accordance with O.Reg Upon completion of the monitoring well installations, Strata completed and filed Water Well Records with the MOE for the wells. A copy of the MOE Water Well Records is provided in Appendix D. The monitoring wells were developed on July 2, 2013 by removing a minimum of three to a maximum of seven standing water column volumes using dedicated Waterra PVC Bailers. The well development activities were completed a minimum of 24 hours prior to the groundwater sampling activities. The monitoring well construction details are provided in Table 2 and on the Borehole Logs in Appendix B. 5.6 Groundwater Field Measurements of Water Quality Parameters Water quality parameters were measured during the low-flow purging and sampling procedure completed on July 3, 2013 at monitoring wells BH02, BH03, BH06, BH08, BH09, BH10, BH12, BH15, BH17, BH18 and BH20. Measurements of the water quality parameters oxidation-reduction potential, dissolved oxygen, temperature, specific conductance, ph, total dissolved solids and salinity were made during purging using a flow-through cell and a YSI-556 water quality meter ( YSI Water Quality Meter ). The YSI Water Quality Meter was calibrated prior to use by the equipment supplier (Pine) in accordance with the manufacturer s specifications. Field-measured parameters were recorded from the YSI Water Quality Meter at regular intervals in order to determine stabilized groundwater geochemical conditions and hence representative groundwater sampling conditions, in general accordance with the criteria stipulated in the Low Flow Sampling Protocol. The field parameter values measured over the course of the low flow sampling activities are provided in the field-measured parameters monitoring logs provided in Appendix E. It should be noted that representative groundwater sampling conditions were determined by Pinchin personnel utilizing the field parameter stabilization criteria noted within the Low 2014 Pinchin Environmental Ltd.

Pinchin File: Flow Sampling Protocol as well as additional factors including total purge time and purge volume. 5.7 Groundwater Sampling The monitoring wells were sampled not less than 24 hours after the completion of well development activities (see Section 5.5) using a low flow sampling methodology consistent with the procedures outlined in the Low Flow Sampling Protocol. Well purging and sampling was completed using a Geotech peristaltic pump powered by a 12-Volt battery. Groundwater was transported to the surface via dedicated 0.64 cm (1/4- inch) inner diameter ( ID ) polyethylene tubing. A YSI Water Quality Meter connected to a flow-through cell was used to monitor groundwater water quality parameters during purging to assess whether water quality parameter stabilization (i.e., steady-state conditions) was achieved prior to sample collection. The flow rate of the peristaltic pump was adjusted to minimize drawdown of the water table and the introduction of sediment into the samples. Once field parameter stabilization was achieved, groundwater samples were collected at each well using the Geotech peristaltic pump and dedicated polyethylene tubing by pumping groundwater directly into new laboratory-supplied sample bottles at a pumping rate of less than 0.5 litres per minute. Following sample collection, the sample bottles were placed into dedicated coolers with ice for storage pending transport to AGAT Laboratories ( AGAT ) in Mississauga, Ontario. Groundwater samples for metals analyses were field-filtered prior to preservation using dedicated 0.45 micron in-line filters. All laboratory sample bottles were pre-filled by the AGAT with preservatives intended to preserve the collected groundwater samples prior to analysis. Formal chain of custody records were maintained between Pinchin and the staff at AGAT. 5.8 Sediment Sampling Sediment sampling was not completed as part of this Phase Two ESA. 5.9 Analytical Testing All collected soil and groundwater samples were delivered to AGAT for analysis. AGAT is an independent laboratory accredited by the Canadian Association for Laboratory Accreditation. Formal chain of custody records of the sample submissions were maintained between Pinchin and the staff at AGAT. AGAT conducted the laboratory analysis in accordance with the MOE document entitled Protocol for Analytical Methods Used in the Assessment of Properties under Part XV.1 of the Environmental Protection Act dated March 9, 2004 and revised on July 1, 2011 ( Analytical Protocol ) Pinchin Environmental Ltd.

31 Phase Two Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario January 2014 Unimin Canada Ltd. Pinchin File: Residue Management Procedures Excess water produced during well purging activities was containerized in two 205-litre clean steel drums stored on the southwest elevation of the Site near the access gate. Pinchin notes that at the time of writing, the drums of excess purge water have not been removed from the Phase Two property. Pinchin will assist the Client in arranging for disposal of these materials by MOE-approved waste haulers at MOE-approved waste management facilities. During the drilling and groundwater sampling activities, no evidence of non-aqueous phase liquid ( PL ) or significant staining was observed in the subsurface. As such, the limited volumes of wash water utilized to clean the sampling equipment were discharged to the ground surface at the Phase Two Property Elevation Surveying In September/October 2013, Dearden and Stanton Ltd. ( DSL ), an OLS, surveyed the horizontal positioning and the vertical elevation of each of the on-site monitoring wells and borehole locations relative to the elevation of local geodetic benchmarks. The geodetic elevations were derived by DSL from RTK (Real Time Kinematic) GPS observations using the CAN-NET NETWORK, and are referred to UTM Zone 17, D 83 (CSRS, CBNv ). Elevation datum is HT2.0. A summary of the borehole and well elevation survey data is provided in Table 2. A plan of survey of the Phase Two Property, as provided by DSL, is attached in Appendix A Quality Assurance and Quality Control Measures The QA/QC protocols that were followed during test-pit/borehole drilling and soil and groundwater sampling so that representative samples were obtained are described in the following sections Sample Containers, Preservation, Labelling, Handling and Custody of Samples Soil and groundwater samples were containerized within laboratory-prepared sample containers in accordance with the Analytical Protocol. The following soil sample containers and preservatives were used: VOCs and PHCs F1: 40 millilitre ( ml ) glass vials with septum-lids, pre-charged with methanol preservative; and PHC F2-F4, PAHs and metals: 250 ml unpreserved amber glass wide-mouth jars with a Teflon TM lined lid Pinchin Environmental Ltd.

Pinchin File: The following groundwater sample containers and preservatives were used: VOCs, BTEX, and PHCs F1: 40 ml amber glass vials with septum-lids, precharged with sodium bisulphate preservative; PHC F2-F4: 500 ml amber glass bottles with Teflon TM lined lids, pre-charged with hydrochloric acid preservative; PAHs: 1 L unpreserved amber glass bottles with Teflon TM lined lids; Metals (excluding hexavalent chromium and mercury): 125 ml acid-rinsed high density polyethylene ( HDPE ) bottles, pre-charged with nitric acid preservative; Hexavalent chromium: 125 ml acid-rinsed HDPE bottles, pre-charged with ammonium sulphate/ammonium hydroxide preservative; and Mercury: 125 ml amber glass bottles with Teflon TM lined lids, pre-charged with hydrochloric acid preservative. Groundwater samples submitted for metals analyses (including hexavalent chromium and mercury) were field-filtered using dedicated 0.45 micron filters. Trip blank water samples for VOC parameter analysis were provided by AGAT in 40 ml amber glass vials filled with VOC-free water. Trip blank samples for the soil sampling program consisted of 40 ml glass vials pre-charged with methanol. Each soil, groundwater and QA/QC sample was labelled with a unique sample identifier along with the company name, sampling date, Pinchin project number and analysis required. Each sample was placed in a cooler on ice immediately upon collection and prior to submission to AGAT for analysis. Formal chain of custody records of the sample submissions were maintained between Pinchin and the staff at AGAT Equipment Cleaning Procedures Dedicated, single-use PVC sample liners were used for each borehole soil sample collected, which precluded the need for drilling equipment cleaning during soil sample collection. Equipment utilized in the soil sampling collection and handling (i.e., spoons used to remove soil from the sample liners or excavator buckets) was cleaned with a solution of Alconox detergent and potable water prior to initial use and between samples. During groundwater sampling and monitoring activities the Geotech peristaltic pump used for purging and sampling, the Heron oil/water interface meter and Waterra WS-2 water level sensor used for water level monitoring, and the YSI Water Quality Meter used for groundwater field parameter measurements were cleaned with a solution of Alconox detergent and potable water prior to and after each measurement Pinchin Environmental Ltd.

33 Phase Two Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario January 2014 Unimin Canada Ltd. Pinchin File: Field Quality Control Measures A total of three field duplicate soil samples were collected by Pinchin during the Phase Two ESA for analysis of one or more of the PCOCs. The frequency of field duplicate soil sample analysis consisted of three duplicate soil samples submitted for analysis of the PCOCs out of a total of 55 soil samples submitted. The field duplicate pairings and corresponding analytical schedules are summarized as follows: Soil sample TP03-SA3 and its corresponding field duplicate DUP-1 were submitted for laboratory analysis of VOCs, PHCs, PAHs and metals; Soil sample BH07-S3 and its corresponding field duplicate DUP-2 were submitted for laboratory analysis of VOCs, PHCs, PAHs and metals; and Soil sample BH17-S10 and its corresponding field duplicate DUP-3 were submitted for laboratory analysis of VOCs, PHCs, PAHs and metals. Two field duplicate groundwater samples were collected by Pinchin during the Phase Two ESA for analysis of the PCOCs. The frequency of field duplicate groundwater sample analysis complied with the requirement that one field duplicate groundwater sample is analyzed for every ten regular groundwater samples submitted for analysis of the PCOCs. The field duplicate pairings and corresponding analytical schedules are summarized as follows: Groundwater samples BH02 and its corresponding field duplicate DUP4, as well as BH20 and its corresponding field duplicate DUP5 were submitted for laboratory analysis of VOCs, PHCs, PAHs and metals. One laboratory-prepared trip blank was analyzed for VOC parameters during the groundwater sampling to comply with the requirement that one trip blank is analyzed for each submission of groundwater samples for VOC analysis. The calibration of the RKI Eagle CGI used for field screening and the YSI Water Quality Meter used for water quality parameter measurements were checked by the equipment supplier (Pine) prior to use in the field by Pinchin. Pine completed the calibration checks in accordance with the equipment manufacturers specifications and/or Pine s SOPs. As described in Section 5.4, calibration checks and recalibration (if required) were completed daily for the RKI Eagle CGI during the drilling program Pinchin Environmental Ltd. Page 29

34 Phase Two Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario January 2014 Unimin Canada Ltd. Pinchin File: QA/QC Sampling Program Deviations With the exception of an insufficient number of duplicate soil samples submitted for laboratory analysis, there were no deviations from the QA/QC sampling program outlined in the SAP Hydraulic Conductivity Testing A rising head hydraulic conductivity test was completed at each monitoring well location on July 2, To conduct the rising head tests hydraulic conductivity, an inertial pump was used to evacuate the well of groundwater, and the recovery rate of the groundwater was monitored and measured with an Oil/Water Interface probe. The rising head hydraulic conductivity test was continued until the measured readings indicated greater than 95% hydraulic recovery within the well. The Bouwer-Rice (1976) method based on the Theims Equation was applied to calculate the geometric mean hydraulic conductivity at each location. The Bouwer-Rice method was chosen as an appropriate method of hydraulic conductivity calculation as no additional water was required for the data collection, and potential cross-contamination was mitigated as only previously dedicated well supplies were required. Once the geometric mean hydraulic conductivity was calculated at each location, the geometric mean of the all the locations was calculated and converted from a rate of metres/second to metres/year. A summary of the calculations and assumptions utilized to calculate hydraulic conductivity at each monitoring well location are provided in Appendix F. 6.0 REVIEW AND EVALUATION 6.1 Geology The Phase Two Property is located in the north/central portion of Midland, Ontario. Based on information obtained from the Ontario Base Map series, the Phase Two Property is situated at an elevation of between approximately 177 and 182 mamsl. Geological data published by the Ministry of Natural Resources and the Ontario Geological Survey have employed the use of the Google Earth mapping service and three-dimensional geographic viewing tool from Google Inc. for viewing multi-layered geological, mining, land and water data. A review of this geological data indicates that the Phase Two Property and surrounding area is located within glaciolacustrine deposits as the dominant landform with the primary native material consisting of well-stratified fine sand, silt and clay Pinchin Environmental Ltd. Page 30

35 Phase Two Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario January 2014 Unimin Canada Ltd. Pinchin File: Bedrock is expected to consist of limestone, dolomite, shale, argillite, sandstone, quartzite, and/or grit. Based on this information, the overburden thickness at the Phase Two Property is expected to be approximately 5.0 to 7.0 m. Based on Pinchin s observations noted during the test pit/drilling activities completed as part of this Phase Two ESA, the aggregate and grass covered ground surface at the Phase Two Property is underlain by sand and gravel, sand and/or silt fill, with occasional cobbles, brick, glass, coal and metal debris fill materials to a maximum depth of approximately 2.0 mbgs. The native soil stratigraphy underlying the surficial soil fill materials is generally comprised of sandy silt to silty clay extending to the maximum depth of borehole investigation of 7.5 mbgs. The overburden/bedrock interface was encountered between 2.9 and 7.5 mbgs. Water level measurements collected as part of this Phase Two ESA indicate that the water table at the Phase Two Property is present at a depth of approximately 2.09 mbgs to 4.95 mbgs. Based on the depth to groundwater, the migration of PCOCs at the Phase Two Property is not anticipated to be influenced by near surface fill materials or underground utility conduits. The soil observed at the Site is comprised mainly of glaciofluvial deposits. All testpits/boreholes were terminated on concrete pier bases, cobbles, bedrock or flowing sands, likely under the influence of the adjacent water body. A description of the subsurface stratigraphy, including geodetic elevations of the top and bottom of each stratigraphical unit encountered during the drilling activities is presented in the cross-sectional drawings attached as Figures 4A and 4B. 6.2 Groundwater Elevations and Flow Direction The wells screens in each well installed by Pinchin were of a consistent length (i.e., 3.05 m) and were installed at depth intervals intended to investigate groundwater quality in the shallow groundwater zone within the unconfined aquifer. The depths to groundwater measured within the on-site monitoring wells on July 2, 2013 ranged from 2.09 mbgs at monitoring well BH02 to 3.06 mbgs at monitoring well BH09. The surveyed ground surface elevations and measured distance between the ground surface elevations and top of riser pipe were utilized in conjunction with the measured depths to groundwater level surfaces to calculate the groundwater level elevation data. The calculated groundwater elevations within the groundwater monitoring wells ranged between mamsl at BH12 to mamsl at BH02. No PL thicknesses were detected in any of the monitoring wells measured with the oil/interface probe on July 2, Pinchin Environmental Ltd. Page 31

36 Phase Two Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario January 2014 Unimin Canada Ltd. Pinchin File: The measured depths to groundwater and calculated groundwater elevation measurements are summarized in Table 3. Also, based on the measured depths to groundwater, it is unlikely that the groundwater flow regime would be influenced by the buried utilities present at the Phase Two Property. The inferred groundwater flow vectors and calculated groundwater elevation contour intervals at the Phase Two Property based on depth to groundwater measurements on July 2, 2013 are shown on Figure 5. The groundwater elevation contours were created using standard triangulation methods with 0.5 m contour spacing. All depth to groundwater measurements in each of the on-site groundwater monitoring wells were used to calculate the groundwater elevation contours. As shown on Figure 5, the calculated groundwater surface elevation contours indicate that groundwater flow across the Phase Two Property is generally to the northwest, towards Midland Bay. 6.3 Groundwater Horizontal Hydraulic Gradients The plotted groundwater surface elevation contours (as shown on Figure 5) were utilized to estimate horizontal hydraulic gradient values for the unconfined aquifer at the Phase Two Property. The horizontal hydraulic gradient can be estimated by dividing the difference between two groundwater contour values by the distance between the two plotted groundwater contours. The distance between select groundwater contours can be determined by drawing a straight line which transects each contour in a perpendicular fashion on the plotted groundwater contour figure. By utilizing multiple sets of groundwater elevations between two known groundwater monitoring well points, which are situated parallel to the groundwater flow, a normalized horizontal hydraulic gradient value for the Phase Two Property (using groundwater surface elevations measured on July 2, 2013) was estimated to be Groundwater Vertical Hydraulic Gradients Nested monitoring wells were not installed at the Phase Two Property as part of the Phase Two ESA. As such, vertical hydraulic gradients were not determined. 6.5 Groundwater Hydraulic Conductivity The hydraulic conductivity of the unconfined aquifer formation at monitoring well locations BH02, BH03, BH06, BH08, BH09, BH10, BH12, BH15, BH17, BH18 and BH20 was estimated utilizing the methods discussed in Section The estimated hydraulic conductivity values ranged from approximately 7.9 x 10-7 m/second at monitoring well location BH09 to 1.4 x 10-6 m/second at monitoring well location BH03. The geometric mean hydraulic conductivity for all of the hydraulic conductivity values estimated at each 2014 Pinchin Environmental Ltd. Page 32

37 Phase Two Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario January 2014 Unimin Canada Ltd. Pinchin File: of the tested monitoring wells was calculated to be approximately 1.13 x 10-6 m/second. The calculated results are consistent with the recovery observations made during the field program and are consistent with the range of hydraulic conductivities for the Site-specific soil types. Therefore, Pinchin has determined that the calculated hydraulic conductivity of 1.13 x 10-6 m/second is acceptable for use as an approximation of the hydraulic conductivity for the Phase Two Property. A summary of the calculations and assumptions utilized to calculate the hydraulic conductivity is provided in Appendix F Darcy s Law Average Linear Velocity Groundwater flow velocity is defined as the hydraulic conductivity multiplied by the hydraulic gradient divided by the porosity of the soil. According to Darcy s Law, using an assumed porosity of 30% to 50% for the unconfined aquifer, a calculated mean hydraulic gradient of and a hydraulic conductivity of 1.13 x 10-6 m/second, the calculated average linear velocity of the groundwater in the unconfined aquifer ranges from approximately 0.94 to 1.17 metres per year ( m/yr ). 6.6 Medium/Fine-Grained Soil Texture Based on the grain size analysis of representative soil samples collected during the Phase Two ESA and the observed stratigraphy at the borehole locations, Pinchin concluded that over one-third of the overburden at the Phase Two Property is medium-textured as defined by O.Reg. 153/ Soil Field Screening Soil vapour headspace concentrations measured in the soil samples collected as part of this Phase Two ESA are presented in the borehole logs and are summarized on Table 1. Soil vapour headspace values measured with the CGI ranged from less than 5 ppm by volume ( ppm v ) in several of the collected soil samples to a maximum of 10% of the lower explosive limit (>11,000 ppm v ) in soil sample BH11-SA8 collected from borehole BH11 at a depth of approximately 5.7 to 6.3 mbgs and BH13-SA5 collected from borehole BH13 at a depth of approximately 3.4 to 4.1 mbgs. Minor petroleum hydrocarbon-like odours were also observed in this soil sample during the drilling activities. Pinchin notes that despite the elevated field screening results for soil samples BH11-SA8 and BH13-SA5, concentrations of PHCs and VOCs in the sample were non-detectable (i.e., below the laboratory reportable detection limit [ RDL ]) Pinchin Environmental Ltd.

Pinchin File: Soil Quality Test Pit Soil Quality A total of 20 test-pits were excavated at the Phase Two Property at the locations shown on Figure 3 in order to assess for the presence of subsurface impacts resulting from the APECs identified in the Pinchin Phase One ESA. Select soil samples were collected from 18 of the 20 excavated test-pits and submitted for laboratory analysis of one or more of the PCOCs. Soil samples were not submitted from test pit TP06 due to termination of the test pit because of excessive cave-in. Soil samples were collected from the areas to TP01 and TP06 during the borehole soil investigation.

44 Phase Two Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario January 2014 Unimin Canada Ltd. Pinchin File: The QA/QC samples collected and submitted for analysis by Pinchin during the Phase Two ESA consisted of the following: Field duplicate soil samples to assess the suitability of field sampling methods and laboratory performance; Field duplicate groundwater samples to assess the suitability of field sampling methods and laboratory performance; and A trip blank water sample to assess whether ambient conditions during transport of groundwater sample containers from the analytical laboratory to the Phase Two Property and back to the analytical laboratory may have biased the groundwater sample results with respect to volatile constituents. In addition to the above, laboratory quality control activities and sample checks employed by AGAT included: Method blanks - where a clean sample is processed simultaneously with and under the same conditions (i.e., using the same reagents and solvents) as the samples being analyzed. These are used to confirm whether the instrument, reagents and solvents used are contaminant free; Laboratory duplicates - where two samples obtained from the sample container are analyzed. These are used to evaluate laboratory precision; Surrogate spike samples - where a known mass of compound not found in nature (e.g., deuterated compounds such as toluene-d8) but that has similar characteristics to the analyzed compounds is added to a sample at a known concentration. These are used to assess the recovery efficiency; Matrix spike samples - where a known mass of target analyte is added to a matrix sample with known concentrations. These are used to evaluate the influence of the matrix on a method s recovery efficiency; and Use of standard or certified reference materials - a reference material where the content or concentration has been established to a very high level of certainty (usually by a national regulatory agency). These are used to assess accuracy. The results of the field QA/QC samples are discussed in the following subsections Soil Duplicate Results During test pit/borehole soil sampling activities, three separate soil duplicate samples pairs were submitted for laboratory analysis. The field duplicate samples were collected by vertically splitting the soil cores into two halves, with one half collected as the regular sample and the other half collected as the field duplicate sample. The sample pairings and corresponding laboratory analyses are as follows: Soil sample TP03-SA3 and its corresponding field duplicate DUP1 were submitted for laboratory analysis of VOCs, PHCs, PAHs and metals; 2014 Pinchin Environmental Ltd.

45 Phase Two Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario January 2014 Unimin Canada Ltd. Pinchin File: Soil sample BH07-SA5 and its corresponding field duplicate DUP2 were submitted for laboratory analysis of VOCs, PHCs, PAHs and metals; and Soil sample BH17-SA4 and its corresponding field duplicate DUP3 were submitted for laboratory analysis of VOCs, PHCs, PAHs and metals. The quality of the analytical results was evaluated by calculating the relative percent difference ( RPD ) for the original and field duplicate samples. The RPDs were calculated using the following equation: Original Concentration Duplicate Concentration RPD = x 100 Original Concentration Duplicate Concentration / 2 RPDs were not calculated unless the parameter concentration in both the original and duplicate sample had detectable concentrations above the corresponding practical quantitation limit ( PQL ) for the parameter, which is equal to five times the lowest laboratory RDL. The calculated RPDs for the original and field duplicate soil samples are presented in Table 5 and have been compared to performance standards provided in the Analytical Protocol. Pinchin notes that although these performance standards only strictly apply to laboratory duplicate samples, they have been considered suitable for comparison to the field duplicate groundwater sample results as well. As indicated in Table 5, the calculated RPDs values were below the performance standards with, with the exception of the following: The RPD values for soil sample pairing BH07-SA5/DUP2, collected from BH07 at a depth of 2.9 to 3.7 mbgs, exceeded the corresponding RPD performance standard of 30% for the analytical results reported for cobalt (RPD of 32%), copper (RPD of 35%), lead (RPD of 67%), nickel (RPD of 40%) and zinc (RPD of 34%); and The RPD values for soil sample pairing BH17-SA5/DUP3, collected from BH17 at a depth of 2.1 to 2.9 mbgs, exceeded the corresponding RPD performance standard of 30% for the analytical results reported for cobalt (RPD of 86%). Based on Pinchin s review of the calculated RPD values for the remainder of the collected soil duplicate sample pairings, the level of observed variance in the reported analytical results is considered acceptable for the purposes of meeting the data quality objectives of this Phase Two ESA Groundwater Sample Duplicate Results Two groundwater duplicate samples pairs (BH02/DUP4 and BH20/DUP5) were collected from monitoring well BH02 and BH20 during the groundwater sampling activities and submitted for laboratory analysis of VOCs, PHCs F1-F4, PAHs and metals. The field duplicate sample was collected immediately following collection of the regular sample Pinchin Environmental Ltd. Page 41

46 Phase Two Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario January 2014 Unimin Canada Ltd. Pinchin File: The calculated RPDs for the original and field duplicate groundwater samples are presented in Table 6 and have been compared to performance standards provided in the Analytical Protocol. As indicated in Table 6, each of the calculated RPDs met the corresponding performance standard. Based on Pinchin s review of the calculated RPD values for the submitted groundwater sample duplicate pairing, the level of observed variance in the reported analytical results is considered acceptable for the purposes of meeting the data quality objectives of this Phase Two ESA Groundwater Trip Blank Results One trip blank, consisting of VOC-free water contained within a set of VOC sample vials, was prepared by AGAT and accompanied the VOC sample containers during transportation to the Phase Two Property and were stored in the coolers with the VOC water samples in the field and during transportation back to AGAT. The trip blank sample was analyzed for VOCs. As indicated in Table 6, the concentrations of the VOC parameters analyzed in the groundwater trip blank sample were below the laboratory RDLs. These findings indicate that ambient conditions during the transportation of the sample containers to and from the Phase Two Property, and during groundwater sampling did not positively bias the VOC parameter analytical results for the groundwater samples Deviations from Analytical Protocol There were no deviations from the holding times, preservation methods, storage requirements and container types specified in the Analytical Protocol during the completion of the Phase Two ESA Laboratory Certificates of Analysis Pinchin has reviewed the laboratory Certificates of Analysis provided by AGAT for the samples submitted during the Phase Two ESA and confirms the following: All laboratory Certificates of Analysis contain a complete record of the sample submission and analysis and meet the requirements of Section 47(3) of O.Reg. 153/04; A laboratory Certificate of Analysis has been received for each sample submitted for analysis during the Phase Two ESA; All laboratory Certificates of Analysis have been included in full in Appendix G; and 2014 Pinchin Environmental Ltd.

Pinchin has also reviewed the laboratory Certificates of Analysis and has confirmed that the results of the analyses are acceptable for the purposes of meeting the data quality objectives of this Phase Two ESA. The following general comments apply to the laboratory Certificates of Analysis received from AGAT as part of this Phase Two ESA: The temperatures of the submitted soil and groundwater samples upon receipt met the sample preservation requirements of the Analytical Protocol of 5 ± 3 ºC; and The custody seal was present and intact on all submissions QA/QC Sample Summary The overall evaluation of the QA/QC sample results indicates no issues with respect to field collection methods and laboratory performance, and no apparent bias due to ambient conditions at the Phase Two Property and during transportation of the sample containers/samples to and from the analytical laboratory. As such, it is Pinchin s opinion that the soil and groundwater analytical data obtained during the Phase Two ESA are representative of actual Site conditions and are appropriate for meeting the objective of assessing whether the soil and groundwater at the Phase Two Property meets the applicable MOE Standards Phase Two Conceptual Site Model The Pinchin Phase One ESA identified a total of nine APECs and corresponding PCOCs which could potentially affect the environmental condition of the subsurface media on, in or under the Phase Two Property.

Pinchin File: The maximum parameter concentrations measured in the submitted soil and groundwater samples are presented in Table 7 and Table 8, respectively. Based on the apparent localized impacts observed, lateral distribution of soil and groundwater impacts is not provided on the Cross-Section Figures 4A and 4B. Lateral delineation of the impacts will be required in order to illustrate the lateral extents of the contaminants on the Cross- Section Figures Physical Setting Based on the work completed as part of this Phase Two ESA, the aggregate or grass covered ground surfaces at the Phase Two Property is underlain by granular soil fill materials to a maximum depth of approximately 2.0 mbgs. Glaciolacustrine deposits underlying the fill materials are present to a depth ranging from approximately 2.0 mbgs to 7.5 mbgs across the Phase Two Property. Bedrock was encountered between approximately 2.9 and 7.5 mbgs across the Phase Two Property. Water level measurements collected as part of this Phase Two ESA indicate that the water table at the Phase Two Property is present at a depth of approximately 2.09 mbgs to 4.95 mbgs. The depth to groundwater measurements coupled with lateral/elevation survey data indicate that the flow direction in the unconfined aquifer at the Phase Two Property is generally northwest. Based on hydraulic conductivity data and the calculated groundwater contours, the groundwater flow velocity in the unconfined aquifer is estimated to be between 0.94 to 1.17 m/yr. The ph values measured in the submitted soil samples were within the limits for nonsensitive sites. The Phase Two Property is also not an area of natural significance and it is not adjacent to, nor does it contain land within 30 metres of, an area of natural significance. As such, the Phase Two Property is not an environmentally sensitive area. However, the Phase Two Property is located within 30 metres of a natural surface water body. No significant volumes of fill material are known to have been imported to the Site. With the exception of the small shed, no current buildings exist on the Phase Two Property or are known to be proposed at this time; however, residential development may occur as part of the Phase Two Property redevelopment Subsurface Utilities and Construction Features The approximate locations of underground utilities and subsurface construction features present at the Phase Two Property have been described in Section 4.3 and are shown in the 2014 Pinchin Environmental Ltd.

The exposure pathways and potential receptors identified for the Phase Two Property were illustrated and summarized in Figure 4A and Figure 4B. The exposure pathways and receptors which Pinchin had considered were as follows: Exposure Pathways GW1 The protection of drinking water component; GW2 The protection of indoor air from vapours originating from groundwater component; GW3 The protection of the aquatic environment component; S1 High-frequency, high-intensity, human health exposure scenario equivalent to that of surface soil at a residential/parkland/institutional or agricultural/other site (children and pregnant women are present); S2 Lower-frequency and lower-intensity, human health exposure scenario without children present and used at commercial/industrial/community sites or at depth at residential/parkland/institutional or agricultural/other sites; S3 Low-frequency, high-intensity, human health exposure scenario without children present that is protective of a worker digging in the soil. It is used for subsurface soils at commercial/industrial/community sites; S-IA Soil to indoor air, for vapour intrusion into a building; S-OA Soil to outdoor air, a volatilization model combined with atmospheric mixing which is protective of outdoor air quality; S-Odour Soil concentrations that will not result in unacceptable odours from direct sniffing of the soil; S-GW1 Soil to potable groundwater, soil values protective of GW1 values; and S-GW3 Soil to groundwater to surface water, soil values protective of aquatic life and GW3 values Pinchin Environmental Ltd.

All reported concentrations in the groundwater samples submitted for analysis of PHCs (F1-F4), VOCs, PAHs and metals satisfied their respective MOE Table 9 Standards. The findings of this Phase Two ESA identified PHCs (F1-F4), VOCs, PAHs and metalsimpacted soil at test-pits TP02, TP101, TP103, TP104, TP105, TP106, TP107, TP109, TP111 and TP112 and boreholes BH08, BH12 and BH14. As such, it is Pinchin s recommendation that Remedial Action Plan ( RAP ) be developed in order to delineate and mitigate the identified impacts. 7.1 Disclaimer This Phase Two ESA was performed for Unimin Canada Ltd. ( Client ) in order to investigate potential environmental impacts at 288 and 420 Bayshore Drive, Midland, Ontario (referred to as the Site or Phase Two Property ). The term recognized environmental condition means the presence or likely presence of any hazardous substance on a property under conditions that indicate an existing release, past release, or a material threat of a release of a hazardous substance into structures on the property or into the ground, groundwater, or surface water of the property. This Phase Two ESA does not quantify the extent of the current and/or recognized environmental condition or the cost of any remediation Pinchin Environmental Ltd. Page 65

70 Phase Two Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario January 2014 Unimin Canada Ltd. Pinchin File: Conclusions derived are specific to the immediate area of study and cannot be extrapolated extensively away from sample locations. Samples have been analyzed for a limited number of contaminants that are expected to be present at the Site, and the absence of information relating to a specific contaminant does not indicate that it is not present. No environmental site assessment can wholly eliminate uncertainty regarding the potential for recognized environmental conditions on a property. Performance of this Phase Two ESA to the standards established by Pinchin is intended to reduce, but not eliminate, uncertainty regarding the potential for recognized environmental conditions on the Site, and recognizes reasonable limits on time and cost. This Phase Two ESA was performed in general compliance with currently acceptable practices for environmental site investigations, and specific Client requests, as applicable to this Site. This report was prepared for the exclusive use of the Client, subject to the conditions and limitations contained within the duly authorized proposal. Any use which a third party makes of this report, or any reliance on or decisions to be made based on it, are the responsibility of the third parties. If additional parties require reliance on this report, written authorization from Pinchin will be required. Pinchin disclaims responsibility of consequential financial effects on transactions or property values, or requirements for follow-up actions and costs. No other warranties are implied or expressed. Furthermore, this report should not be construed as legal advice. Pinchin will not be responsible for any consequential or indirect damages. Pinchin will only be held liable for damages resulting from the negligence of Pinchin. Pinchin will not be liable for any losses or damage if the Client has failed, within a period of two years following the date upon which the claim is discovered within the meaning of the Limitations Act, 2002 (Ontario), to commence legal proceedings against Pinchin to recover such losses or damage. Pinchin makes no other representations whatsoever, including those concerning the legal significance of its findings, or as to other legal matters touched on in this report, including, but not limited to, ownership of any property, or the application of any law to the facts set forth herein.

111 Sampling and Analysis Plan for Phase Two Environmental Site Assessment 288 and 420 Bayshore Drive, Midland, Ontario Unimin Canada Ltd. Pinchin File: Sampling System Pinchin will utilize a judgemental sampling system as part of the Phase Two ESA to assess the soil and groundwater quality in relation to the APECs identified during the completion of the Phase One ESA. The identification of APECs related to potential sources of contamination at off-site properties adjacent to the Site permits the use of judgemental sampling. The test pit, borehole, monitoring well, soil and groundwater sample locations have been selected to represent worst case locations at points near the Site boundary where the likelihood of potential contaminants of concern ( PCOCs ) impacts from the adjacent properties is considered to be the greatest; on-site APEC areas that represent worst case locations within the property boundaries where the likelihood of PCOCs exist; or, areas in the vicinity of where contaminants have been discovered, where delineative limits are intending on being met. 4.0 Scope of Work The scope of work for the Phase Two ESA will consist of the following activities: Conduct an initial Site visit to specifically locate the areas of proposed testing, discuss sampling logistics and gather information from a Site representative; Contact Ontario One-Call and retain the services of a privately contracted utility locating company to identify the locations of buried and overhead utility services prior to any test pitting or drilling activities; Retain the services of a qualified excavation contractor to conduct soil test pit excavating activities during both the initial investigation and supplemental delineative investigation; Retain the services of an Ontario Ministry of the Environment ( MOE ) Licensed Well Contractor, in accordance with Ontario Well Regulation 903/90 (as amended) to conduct all borehole drilling and monitoring well installation activities; Excavate a total of six test pits at the Site to a depth of approximately 3.0 metres below ground surface ( mbgs ). Depth of the test pits will be determined in the field (shallower or deeper) based on depth to groundwater, refusal on bedrock or boulders, etc.; Drill a total of twenty boreholes at the Site to a depth of approximately 4.6 mbgs, with eleven of the boreholes completed as groundwater monitoring wells to facilitate future groundwater monitoring and sampling at the Site. Depth of the boreholes will be determined in the field (shallower or deeper) based on depth to groundwater, refusal on bedrock or boulders, etc.; Excavate an additional fourteen test pits at the Site to a depth of 4.6 mbgs. Depth of the test pits were determined based on the estimated depths of impacts needing to be delineated; Field screen all collected soil samples using the following methodologies to determine the most apparent worst-case soil samples: The measurement of soil sample headspace for total organic vapours by using a combustible gas indictor (i.e., RKI Eagle or equivalent) calibrated to hexane and a photoionization detector ( PID ) calibrated to isobutylene; and Visual and olfactory considerations; 2014 Pinchin Environmental Ltd.

119 SCOPE AND APPLICATION A significant portion of Pinchin's field activities relates to sampling/investigative activities that involve subsurface drilling. This typically requires Pinchin to contract or subcontract with a drilling finn to penetrate the ground for sample collection or well installation using mechanical systems. The following discussion is generic in nature, does not detail specific drilling methods, but describes the typical drilling program preparation and drilling program closure activities that should be followed for most Pinchin managed programs. PRIOR PLANNING AND PREPARATION When preparing for a drilling program a number of setup and logistical activities must take place before ground is broken. The following are the tasks undertaken once a contractor is selected and a program start has been established. The following does not address contractual arrangements, Work Plan development, or Health and Safety Plan (HASP) development which must be completed well before project startup. i) Site selections for proposed drill and/ or sampling locations. ii) Utility clearances. iii) Arrange access to the site. Assemble well keys and site keys. iv) Contact analytical laboratory to arrange: o Laboratory; o Glassware/sample jars; o Cooler(s); o Shipping details; o Start date; and o Expected duration. v) Contractor mobilization, equipment and material check. vi) Contractor Health and Safety Orientation/Hazard review. vii) Site selection of decontamination pad and drum staging area (if applicable). viii) Pre-plan methods for handling and disposal of drill cuttings, wash waters, and spent decontamination fluids. PROCEDURES Once the prior planning and preparation activities are completed, the drilling program can proceed. The typical series of events which takes place is: Locating and marking of boring location; Decontamination of sampling and drilling equipment; Advance borehole utilizing the approved method as outlined in the work program; EDR-SOP-05 Page 1

120 Logging of the borehole by Pinchin protocol; Soil collection and field screening; Monitoring well installation (if applicable); Collection of groundwater samples (if monitoring well installed); and Surveying of borehole location and elevations. TRAINING AND RESPONSIBILITY The Operations Manager is responsible for identifying the initial training needs of the EDR Group staff and ensuring that staff is trained and competent before undertaking work assignments. All trained personnel are responsible for identifying coaching or re-training needs (if they are uncomfortable with work assignments that have been assigned). FOLLOW-UP ACTIVITIES The following shall be performed once field activities are complete: i) Make sure that the Site is secured and that the Site and well keys are returned. ii) Notify the contract laboratory as to when to expect samples. The chain-of-custody and cover letter, indicating the parameters and numbers of samples, shall be enclosed in the sample cooler. iii) File all completed field notes and forms. iv) A Brief / De-Brief session must be conducted in order to complete the task. The careful application of Health & Safety Training by each employee is an integral part of all activities and is assumed as part of this SOP.

124 SCOPE AND APPLICATION This SOP presents a description of the methods employed for the installation of boreholes and the collection of subsurface soil samples. Boreholes are typically installed to define geologic conditions for hydrogeologic and geotechnical evaluation; to allow the installation of monitoring wells and piezometers; and to allow the collection of subsurface soil samples (generally above the water table) for chemical analysis. Several methods are available for the collection of shallow subsurface soil samples (e.g., hand augers, post-hole augers). However, the most common method used by Pinchin to advance boreholes is drilling using a drill rig equipped with either direct-push tooling, consisting of dual-tube tooling, macro-core tooling, solid-stem augers and hollow-stem augers (HSA). PRIOR PLANNING AND PREPARATION The following activities must be undertaken prior to undertaking a borehole installation and subsurface soil sampling program. i) Review the sampling and analysis plan, work program, project documents, and the health and safety requirements with the Project Manager. ii) Complete an equipment requisition form and assemble all equipment and supplies. iii) Obtain a site plan (from the proposal/workplan) and any previous stratigraphic logs. Determine the exact number and location of boreholes to be installed and the depths of samples for chemical analysis. iv) Contact the selected laboratory to arrange/determine: o Laboratory; o Glassware/ sample jars; o Cooler; o Shipping details; and o Turnaround time. v) Establish borehole locations in field using available landmark or by surveying methods if necessary. vi) Arrange for utility clearance of franchised utilities and site utilities. vii) Determine notification needs with the Project Manager. Have the regulatory groups, Client, landowner, Pinchin personnel, and laboratory been informed of the sampling event? viii) Determine the methods for handling and disposal of drill cuttings, wash waters, and spent decontamination fluids. PROCEDURES EDR-SOP-06 Page 1

125 Once the prior planning and preparation activities are completed, the borehole drilling program can proceed. Checklists for drilling activities are included in the Phase II Field Forms directory of the Pinchin EMS Drive (S:\Phase II Field Forms). The typical series of events which takes place is: Locating and marking of borehole locations (if not already completed); Final visual examination of proposed drilling area for utility conflicts; Equipment decontamination; Advancement of borehole and collection of the soil sample; Abandonment of boreholes; Surveying of borehole locations and elevations; and Field note completion and review. Location and Marking of Boreholes / Final Visual Check The proposed borehole locations marked on the site plan are located in the field and staked. On most sites, this will likely be done either the day of drilling or several days in advance of the drill rig arriving on site. Unless boreholes are to be installed on a fixed grid, the proposed locations are usually strategically placed to assess site conditions. Any borehole (and all the associated records) which is completed with casing as a temporary or permanent monitor well, will be designated by the monitor well number only (i.e., MW0l). Boreholes drilled strictly as soil test borings in which no casing is set will be designated by the boring number only (i.e., BH01). Once the final location for the proposed boring has been selected and utility clearances are complete, one last visual check of the immediate area should be performed before drilling proceeds. This last visual check should confirm the locations of any adjacent utilities (subsurface or overhead) and verification of adequate clearance. If sewers or conduits exist in the area, any access manholes or chambers should be opened and the conduit/sewer alignments confirmed. Do not enter manholes unless confined space procedures are followed. In some instances, the use of a hydro-vac unit may be required to expose the upper 1.5 meters of soil within the location of a known utility. The hydro-vac uses a combination of high-pressure water and high-suction vacuum (in the form of a vacuum truck) to excavate soil. This is also known as daylighting. CAUTION: DO NOT ASSUME PLAN DETAILS REGARDING PIPE ALIGNMENTS / POSITION. VISUALLY CHECK PIPE POSITION WHEN DRILLING NEAR SEWERS. PERSONNEL SHOULD ALSO BE ALERT TO ADDITIOL PIPING PRESENCE IF THE PLANS ARE OUTDATED! If it is necessary to relocate any proposed borehole due to terrain, utilities, access, etc., the Project Manager must be notified and an alternate location will be selected. EDR-SOP-06 Page 2

126 Equipment Decontamination for Environmental Sites Prior to use and between each borehole location at an environmental site, the drilling and sampling equipment must be decontaminated. All decontamination must be conducted in accordance with the project-specific plans and regulatory standards. The minimum wash procedure for decontamination of this equipment is: High pressure hot water detergent wash (brushing as necessary to remove particulate matter); and Potable, hot water, high pressure rinse. The clean augers / drill stems are covered with clean plastic sheeting to prevent contact with foreign materials. For geotechnical, geologic, or hydrogeologic studies where contaminants will not be present, it is sufficient to clean the drilling equipment simply by removing the excess soils. On environmental sites, the sampler is cleaned as follows: Wash with clean potable water and laboratory detergent, using a brush as necessary to remove particulates; Rinse with tap water; or rinse with deionized water; Rinse with 10 percent nitric acid (only if samples are to be analyzed for metals); Rinse with deionized water; Rinse with appropriate solvent (pesticide grade isopropanol, methanol, acetone, and hexane); Rinse again with deionized water; Air dry as long as possible; and Wrap split-spoon samplers in aluminum foil to prevent contamination. CAUTION: Check the Quality Assurance Project Plan to confirm the cleaning protocol. Use of incorrect cleaning protocol could invalidate chemical data. Sample Collection The boring is advanced incrementally to permit intermittent or continuous sampling. Test intervals and locations are normally stipulated by the project engineer or geologist. Typically, the depth interval for sampling is 2.5 to 5 feet [0.75 to 1.5 m] or less in homogeneous strata with at least one test and sampling location at every change of strata. In some cases, samples are taken continuously. When completing environmental sampling, always change gloves between collecting subsequent soil samples to prevent cross-contamination. All tools (e.g., samplers, spatulas, etc.) must be field cleaned prior to use on each sample. The drilling method is to be selected based on the subsurface conditions. Each of the following procedures has proven to be acceptable for specific subsurface conditions: Open-hole rotary drilling method; Continuous flight hollow-stem auger method (with inside diameter between 2.2 and 6.5 inches); EDR-SOP-06 Page 3

127 wash boring method; and Continuous flight solid auger method (with auger diameter between 2.2 and 6.5 inches). Several drilling methods are not acceptable. These include: jetting through an open tube sampler and then sampling when the desired depth is reached; use of continuous flight solid auger equipment below the groundwater table in non-cohesive soils; casing driven below the sampling depth prior to sampling; and advancing a borehole with bottom discharge bits. It is not permissible to advance the boring for subsequent insertion of the sampler solely by means of previous sampling when performing standard penetration testing. The following subsections describe the specific protocol for Direct-Push sampling, Standard Penetration Testsampling and Shelby Tube sampling. Direct Push Sampling This method is most commonly used at Pinchin to obtain representative samples of the subsurface soil material at the site. Direct-Push sampling is achieved by driving a steel sampler into the subsurface at 1.5 m intervals until the desired depth is achieved. The samplers are advanced by the drilling rig by means of a hydraulic hammer that delivers approximately 1,920 blows per minute. The steel sampler is equipped with a dedicated PVC sample liner which collects the soil driven into the sampler as it is advanced. There are generally two (2) methods of direct-push drilling which may be used: Dual-tube Sampling; and Macro-core Sampling. A dual-tube sampler consists of an 8.25 centimeter ( cm ) inner diameter steel tooling ( outer tube ), equipped with a steel cutting-shoe affixed to the advancing end. A smaller diameter steel tooling, consisting of a 5.75 cm diameter (inner tube) which fits within the outer tube and contains a PVC sample liner within. These two (2) tubes form the completed dual tube sampler. The completed dual-tube sampler has a length of 1.5 m and is driven at 1.5 m intervals. A macro-core sampler consists of the smaller inner tube (mentioned above) used independently. The macrocore sampler measures approximately 1.5 m in length and is driven using smaller diameter tooling in 1.5 m intervals. The difference in drilling methods is typically determined by soil conditions. Where soil conditions consist of tight or dense soil types (i.e. silts or clays), the macro-core sampling method may be used as this method provides less resistance. In soil types that are less resistive (i.e. loose sands, gravels, or silts), the dual tube sampler may be used. The recovered sample tube is retrieved from the ground and is cut open by the drillers helper and left closed until the soil sample is ready for collection and visual examination. Pinchin staff should never attempt to use the liner cutting tools or handle the sample liners prior to be delivered by the drillers helper. For methodology on collecting the soil samples please refer to Pinchin Standard Operating Procedure for soil sampling provided on the Pinchin EMS drive (S:\SOPs\EDR-SOP-19 - Soil Sampling). EDR-SOP-06 Page 4

128 Standard Penetration Testing (SPT) Sampling and Testing Procedure This method is used to obtain representative samples of subsurface soil materials and to determine a measure of the in situ relative density of the subsurface soils. The test methods described below must be followed to obtain accurate SPT values. SPT sampling is performed by using a split barrel sampler in accordance with ASTM D1586. The split barrel sampler, or split spoon, consists of an 18- or 24-inch long, 2-inch outside diameter tube, which comes apart length wise into two halves. Once the borehole is advanced to the target depth and the borehole cleaned of cuttings, representative soil samples are collected in the following manner: The split-spoon sampler should be inspected to ensure it is properly cleaned and decontaminated. The driving shoe (tip) should be relatively sharp and free of severe dents, off-sets and distortions; The cleaned split-spoon sampler is attached to the drill rods and lowered into the borehole. Do not allow the sampler to drop onto the soil; After the sampler has been lowered to the bottom of the hole, it is given a single blow to seat it and make sure that it is in undisturbed soil. If there still appears to be excessive cuttings in the bottom of the borehole, remove the sampler from the borehole and remove the cuttings; and Mark the drill rods in three or four successive 6-inch (0.15 m) increments, depending on sampler length, so that the advance of the sampler under the impact of the hammer can be easily observed for each 6- inch (0.15 m) increment. The sampler is then driven continuously for either 18 or 24 inches (0.45 or 0.60 m) by use of a 140-pound (63.5 kg) hammer. The hammer may be lifted and dropped by either the cathead and rope method, or by using a trip, automatic, or semi-automatic drop system. The hammer should free-fall a distance of 30 inches (±1 inches) (760 mm, ±25 mm) per blow. Measure the drop at least daily to ensure that the drop is correct. To ensure a free-falling hammer, no more than 2-1/4 turns of the rope may be wound around the cathead (see ASTM D1586). The number of blows applied in each 6-inch (0.15 m) increment is counted until one of the following occurs: A total of 50 blows have been applied during any one of the 6-inch (0.15 m) increments described above; A total of 100 blows have been applied; There is no advancement of the sampler during the application of ten successive blows of the hammer (i.e., the spoon is "bouncing" on a stone or bedrock); or The sampler has advanced the complete 18 or 24 inches (0.45 or 0.60 m) without the limiting blow counts occurring as described above. In some cases where the limiting number of blow counts has been exceeded, Pinchin may direct the driller to attempt to drive the sampler more if collection of a greater sample length is essential. On the field form, record the number of blows required to drive each 6-inch (0.15 m) increment of penetration. The first 6 inches is EDR-SOP-06 Page 5

129 considered to be a seating drive. The sum of the number of blows required for the second and third 6 inches (0.15 m) of penetration is termed the "standard penetration resistance" or the "N-value". Note: If the borehole has sloughed and there is caved material in the bottom, the split spoon may push through this under its own weight, but now the spoon is partially "pre-filled". When the spoon is driven the 18 or 24 inches representing its supposedly empty length, the spoon fills completely before the end of the drive interval. Two problems could arise: 1. The top part of the sample is not representative of the in-place soil at that depth; and 2. The SPT value will be artificially higher toward the bottom of the drive interval since the spoon was packed full. These conditions should be noted on the field log. The sampler is then removed from the borehole and unthreaded from the drill rods. The open shoe (cutting end) and head of the sampler are partially unthreaded by the drill crew and the sampler is transferred to the geologist / engineer work surface. Note: A table made out of two sawhorses and a piece of plywood is appropriate, or a drum, both covered with plastic sheeting. The open shoe and head are removed by hand, and the sampler is tapped so that the tube separates. Note: Handle each split spoon with clean disposable gloves if environmental issues are being investigated. Measure and record the length of sample recovered making sure to discount any sloughed material that is present on top of the sample core. Caution must be used when conducting SPT sampling below the groundwater table, particularly in sand or silt soils. These soils tend to heave or "blow back" up the borehole due to the difference in hydraulic pressures between the inside of the HSA and the undisturbed soil. To equalize the hydraulic pressure, the inside of the HSA must be filled with water or drilling mud. The drilling fluid level within the boring (or within hollow-stem auger) needs to be maintained at or above the in situ groundwater level at all times during drilling, removal of drill rods, and sampling. Since heave or blow back is not always obvious to the driller, it is essential that the water level in the borehole always be maintained at or above the groundwater level. Heaving conditions and the use of water or mud should be noted on the field logs. SPT sampling below the water table in sands and silt occasionally results in low SPT values being obtained due to the heaving effect disturbing the soil, especially if the water level in the hole has not been maintained at the in situ water level. Suspect low N values should be noted on the field logs. If it is critical to have accurate N values below the water table, other methods can be employed, such as conducting a dynamic cone penetration test. This quick and easy test involves attaching a cone shaped tip to the end of the drill rods, and driving the tip into the ground similar to the SPT method, except that the borehole is not pre-augered. Cones may be driven 20 to 40 feet through a formation without augering. Blow counts are recorded for each 1-foot (0.3 m) of advancement. Consult the Project Manager if such conditions are unexpectedly encountered. A variation of split barrel sampling involves the use of a longer barrel in conjunction with hollow stem augers. The sampling barrel is installed inside the auger with a swivel attachment to limit rotation of the barrel. After completion of a 5-foot EDR-SOP-06 Page 6

130 auger penetration, the auger is left in place and the barrel retrieved from the borehole. The sampler should be handled and the sample retrieved in the same way as described above for SPT sampling. Thin Walled Samplers (Shelby Tubes) Thin-walled samplers are used to collect relatively undisturbed samples (as compared to split-spoon samples) of soft to stiff clayey soils. Shelby tubes are commonly used. The Shelby Tube has an outside diameter of 2 or 3 inches and is 3 feet long. These undisturbed samples are used for certain laboratory tests of structural properties (consolidation, hydraulic conductivity, shear strength) or other tests that might be influenced by sample disturbance. Procedures for conducting thin-walled tube sampling are provided in ASTM D1587, and are briefly described below: The soil deposit being sampled must be cohesive in nature, and relatively free of sand, gravel, and cobble materials, as contact with these materials will damage the sampler; Clean out the borehole to the sampling elevation, using whatever method is preferred that will ensure the material to be sampled is not disturbed. If groundwater is encountered, maintain the liquid level in the borehole at or above groundwater level during the sampling operation; bottom discharge bits are not permitted. Side discharge bits may be used, with caution. Jetting through an open-tube sampler to clean out the borehole to sampling elevation is not permitted. Remove loose material from the center of a casing or hollow-stem auger as carefully as possible to avoid disturbance of the material to be sampled; Place the sample tube so that its bottom rests on the bottom of the hole. Advance the sampler into the formation without rotation by a continuous and relatively rapid motion - usually hydraulic pressure is applied to the top of the drill rods; Determine the length of advance by the resistance and condition of the formation, but the length shall never exceed 5 to 10 diameters of the tube (in sands) and 10 to 15 diameters of the tube (in clays); In no case should the length of advance be greater than the sample-tube length (minus; an allowance for the sampler head, and a minimum of 3 inches for cuttings); The tube may be rotated to shear the bottom of the sample 2 to 3 minutes after pressing in, and prior to retrieval, to ensure the sample does not slide out of the tube. Lift the weight of the rods off the tube prior to rotating; Withdraw the sampler from the formation as carefully as possible in order to minimize disturbance of the sample; and Package and transport the sample in accordance with standard protocol. Occasionally, the Project Manager may require extraction of the sample from the tube in the field. The following procedure should be followed. A sample extruder (which consists of a clamp arrangement to hold the tube and a hydraulic ram to push the sample through the tube) is usually mounted on the side of the rig. To prevent cross-contamination, be certain that the extruder is field cleaned between each sample; EDR-SOP-06 Page 7

131 The sample is then extruded into a carrying tray; these are often made from a piece of 4-inch or 6-inch diameter PVC pipe, cut lengthwise. Be certain that the carrying tray is field cleaned between each sample. The sample is carried to the work station to describe the sample, trim the potentially cross contaminated exterior, and place it in the appropriate container; and The Shelby tube may then be thoroughly field cleaned and decontaminated for reuse. Since they are thin-walled, the tubes are easily damaged, crimped, or otherwise distorted during handling or pushing. The Shelby Tube should be inspected before use and any which are significantly damaged should be rejected. Communication of Field Findings Field findings should be communicated frequently with the office technical staff (usually the Project Manager) responsible for the program. This communication allows the office staff: to confirm that the investigation meets the intent of the Work Plan; to alter procedures and sampling protocol if soil conditions are markedly different from those assumed; and to assist in determining screening intervals for piezometers or monitoring wells. Call office staff no later than the completion of the first borehole orsooner if possible. Be prepared to discuss the results by faxing the field logs beforehand (wherever possible) and by having a copy of the field log in hand when on the telephone. Call after each borehole and call before leaving the site unless otherwise instructed. Borehole Abandonment Following completion of the borehole it must be properly abandoned in accordance with the project documents. Some locales have requirements or standards of practice that require filling the borehole with bentonite or grout. Note: The integrity of any underlying confining layer must be restored to prevent chemical cross-contamination or hydraulic crossconnection. This is true for all sites, regardless of the known presence or absence of contaminants. This normally requires grouting of the borehole within the zone of the confining layer. Whenever possible, the cuttings shall be returned to the borehole to within 1 foot of the ground surface. The remainder of the borehole should be topped off with material consistent with the surrounding ground surface. Excess cuttings are usually collected in drums or a lugger box or spread on the surrounding ground surface consistent with the protocols specified in the project documents. Check with the Project Manager to determine the method for handling drill cuttings. Note: Always include the method of abandonment on the field log book. Borehole Tie-In/Surveying The recording of the locations of boreholes on the site plan is extremely important. This may be accomplished by manual measurement (i.e., swing ties) and surveying. Manual measurements for each borehole must be tied into three permanent features (e.g., buildings, utility poles, hydrants, etc.). Diagrams with measurements should be included in the field book. In addition to manual measurements, surveying with respect to a geodetic benchmark and a site coordinate system is often completed at larger sites. EDR-SOP-06 Page 8

132 Note: Manual field measurements are always necessary regardless of whether a survey is completed. Manual measurements allow future identification of the sample/drill site without the need of a survey crew to locate positions using a grid system. Field Notes The field notes must document all the events, equipment used, and measurements collected during the sampling activities. The field notes must be legible and concise such that the entire borehole installation and soil sampling event can be reconstructed later for future reference. The field notes will be recorded on the field forms and field book. All field book/ form entries must be made in blue or black ink and any changes/ corrections shall be stroked out with a single line and initialed and dated to indicate who and when the correction was made. FOLLOW-UP ACTIVITIES The following shall be performed once field activities are complete.

137 GENERAL The design and installation of monitoring wells involve the drilling of boreholes into various types of geologic formations. Designing and installing monitoring wells may require several different drilling methods and installation procedures. It is important that the drilling method or methods used minimize disturbance of subsurface materials, do not contaminate the subsurface soils and groundwater, and do not provide a hydraulic link between different hydrogeologic units. Samples collected from installed monitoring wells must not be contaminated by drilling fluids or by the drilling procedures. The drilling equipment shall be decontaminated before use and between borehole locations to prevent cross-contamination of contaminants between monitoring wells where contamination has been detected or is suspected. In reality, it is always best to decontaminate the drilling equipment between each use. The only case where decontamination is not required occurs when drilling for geologic information in known clean areas. Additionally, pre-cleaned monitoring well construction materials shall be used in order to prevent potential introduction of contaminants into the formation. PRIOR PLANNING & PREPARATION When designing and constructing monitoring wells the following questions shall be considered: i. What contaminants are to be monitored? ii. What kinds of analyses are needed? iii. What are the geologic / hydrogeologic conditions at the site? iv. What is the anticipated total depth of the well? v. What are the potential health and safety hazards? vi. Are wells going to serve for monitoring, pumping test, or extraction purposes? vii. What types of well construction materials are to be used? DRILLING METHOD The following drilling methods are listed in order of preference; however, final selection will be based on actual site conditions. Hollow-Stem Auger The hollow-stem continuous-flight auger (HSA) is among the most frequently used in the drilling of monitoring wells. The primary advantages of hollow-stem augering are that: Generally, no additional drilling fluids are introduced into the formation; EDR-SOP-07 Page 1

138 Representative geologic soil samples can be easily obtained using split-spoon samples in conjunction with the hollow-stern augers; and Monitoring wells can be installed through the augers eliminating the need for temporary borehole casings. Installing monitoring wells through hollow-stem augers is a relatively simple process although precautions need to be taken to ensure that the well is properly backfilled. This can be particularly problematic in cases where flowing sand is present. Hollow-stem augers are available with inside diameters of 2.5, 3.25, 4.0, 4.25, 6.25, 8.25, and inches. The most commonly used are 4.25 inches for 2-inch (5 cm) monitoring wells and 6.25 inches for 4-inch (10 cm) monitoring wells. Boreholes can usually be drilled with hollow-stem augers to depths up to 100 feet (30 m) in unconsolidated clays, silts, and sands. Removing augers in flowing sand conditions while installing monitoring wells may be difficult since the augers have to be removed without being rotated. A bottom plug or pilot bit assembly should be utilized to keep out soils and/or water that have a tendency to plug the bottom of the augers during drilling. If flowing sands are encountered, potable water (analyzed once for contaminants of concern) may be poured into the augers to equalize the pressure to keep the formation materials and water from coming up into the auger once the bottom plug is removed. Dual-Wall Reverse Circulation Air Method of Drilling This method consists of two concentric strings of drill pipe (an outer casing and a slightly smaller inner casing). The outer drill pipe is advanced using rotary drilling with a donut-shaped bit attached to the dual casing string cuts an area only the width of the two casings and annulus between. Compressed air is continually forced down the annulus between the inner casing carrying the drill cuttings and groundwater. At the surface, the inner casing is connected to a cyclone hopper where the drill cuttings and groundwater fall out the bottom of the hopper, and air is disbursed out the top. The dual wall provides a fully cased borehole in which to install a monitoring well. The only soil or groundwater materials exposed at any time are those at the drill bit. Therefore, the potential for carrying contamination from one stratum to another is minimal. Depth-specific groundwater samples can be collected during drilling; however, since the groundwater is aerated, analysis for volatile compounds may not be valid. Rotosonic Drilling This method consists of a combination of rotation with high frequency vibration to advance a core barrel to a desired depth. Once the vibration is stopped, the core barrel is retrieved, and the sample is vibrated or hydraulically extracted into plastic sleeves or sample trays. Monitoring wells shall be installed through an outer casing. Rotosonic drilling generally requires less time than more traditional methods. Continuous, relatively undisturbed samples can be obtained through virtually any formation. Conventional sampling tools can be employed as attachments (i.e., hydropunch, split spoon, Shelby tube, etc.). No mud, air, water, or other EDR-SOP-07 Page 2

139 circulating medium is required. The rotosonic method can drill easily through formations such as rock, sand, clay, or glacial till. The main limitation of this method is the availability of equipment. Rotary Method This method consists of a drill rod attached to a drill bit (soils: tricone, drag; rock: button studded, diamond studded) that rotates and cuts through the soils and rock. The cuttings produced are forced to the surface between the borehole wall and the drill rod by drilling fluids which generally consist of water, drilling mud, or air. The drilling fluids not only force the cuttings to the surface but also keep the drilling bit cool. Using rotary methods for well installations can be difficult as it usually requires several steps to complete the installation. First, the borehole is drilled; then temporarily cased; then the well is installed; and then the temporary casing is removed. In some cases, the borehole may remain open without installing a casing but this will only occur in limited instances (i.e., cohesive soils). Water Rotary When using water rotary, the potable water supply shall be analyzed for contaminants of concern. Water rotary is the preferred rotary method since the potable water is the only fluid introduced into the borehole during drilling. However, the use of water as a fluid is generally only successful when drilling in cohesive soils. The use of potable water also reduces well development time. Air Rotary (typically used in rock) When using air rotary, the air compressor must have an in-line oil filter system assembly to filter the oil mixed with the air coming from the compressor. This will help eliminate contaminant introduction into the formation. The oil filter system shall be regularly inspected. Air compressors not having an in-line oil filter system are not acceptable for air rotary drilling. A cyclone velocity dissipater or similar air containment system shall also be used to funnel the cuttings to one location rather than letting the cuttings blow uncontrolled out of the borehole. Air rotary may not be an acceptable method for well installation where certain contaminants are present in the formation. Alternatively, it may be necessary to provide treatment for the air being exhausted from the borehole during the installation process. Mud Rotary In some areas, mud rotary is the least preferred rotary method because contamination can be introduced into the borehole from the constituents in the drilling mud. The drilling muds are generally non-toxic and do not introduce contaminants into the borehole; however, it is possible for mud to commonly infiltrate and affect water quality by sorbing metals and polar organic compounds (Aller et al., 1991). Chemical composition and priority pollutant analysis may be obtained from the manufacturer. Mud rotary shall utilize only potable water and pure (no additives) bentonite drilling muds. The viscosity of the drilling mud shall be kept as low as possible in order to expedite well development. Proper well development is essential to ensure the removal of all the drilling mud and to return the formation to its previously undisturbed state. EDR-SOP-07 Page 3

140 Well Point In some limited cases, well points (sand points) are driven into place without the use of augers. This method provides no information on the geologic condition (other than the difficulty of driving which may be related to formation density). Well points are most often used simply to provide dewatering of a geologic unit prior to excavation in the area. Well points are also used in monitoring shallow hydrogeologic conditions such as in stream beds. FIELD PROCEDURES The following presents the field procedure requirements and techniques for the completion of overburden and bedrock monitoring well installations. INSTALLATION REQUIREMENTS Annular Space The borehole diameter shall be sufficient that well construction may proceed without any major difficulties. To assure adequate size, a minimum 2-inch (5 cm) annular space is required between the well casing and borehole wall (or the hollow-stem auger wall). The 2-inch (5 cm) annular space will allow a minimum l.5-inch (4 cm) tremie tube for placing the filter pack, seal, and grout at the specified intervals. An annular space less than 2 inches (5 cm) is not acceptable. When installing a well inside of hollow-stem augers, the inside diameter (ID) of the augers is the area to be considered when determining the 2-inch (5 cm) annular space. Instrumentation Details Prior to insertion into the augers or borehole, the well assembly (i.e., well screen and riser components) must be measured to record its exact total length, and the length of each component. Once this length is known, well placement may proceed. Placement problems are easily identified by measuring the amount of riser stick-up during installation. Filter Pack Placement [Primary Filter Pack (see ASTM 05092)] When placing the primary filter pack into the borehole, a minimum of 6 inches (0.15 m) of the primary filter pack material shall be placed under the bottom of the well screen to provide a firm footing. In cases where DPL is present, it may not be desirable to have a filter pack "sump" beneath the well and therefore this requirement may be deleted. The elevation for the top of the filter pack is to be selected in the field based upon the geologic conditions encountered. For shallow overburden wells, it is common to extend the filter pack to the top of the water table plus a few extra feet to account for the anticipated fluctuation of the water table due to seasonal effects. EDR-SOP-07 Page 4

141 For deeper overburden wells, it is common to select a specific hydrogeologic unit to monitor. The filter pack should span that specific hydrogeologic unit only. The filter pack should never extend through a confining layer causing two or more separate permeable layers to become connected. Where practical, the filter pack should extend a minimum of 2 feet above the top of the well screen. The filter pack should be placed by the tremie method. Placing the primary filter pack by "pouring" may be acceptable if you are sure that the filter pack is reaching the assigned depth. Primary filter pack placement must be carefully performed concurrent with the removal of the augers when collapsing borehole conditions exist. The filter pack level must be maintained within the augers or temporary casing to ensure a proper filter pack "envelope" around the well screen. Primary filter pack placement is typically a 'delicate' operation, requiring a careful balance between: placement of too much sand and locking the well components within the augers, or an insufficient amount of sand which then allows formation materials to collapse around the well screen area. A good well installer constantly checks the filter pack level as the augers are removed, adjusting the amount and rate of filter pack placement accordingly. On occasion, it may be necessary to add potable water within the augers to maintain a positive pressure head on the formation materials which (when certain conditions are encountered), will flow into the water string in an effort to equilibrate with exterior levels. Typically, this condition exists when sandy/silty soils are encountered below the static groundwater level. If potable water is added, the volume used must be recorded and additional purging volumes may be required. Secondary Filter Pack (see ASTM D5097 and D5092) A secondary filter pack is a layer of material placed in the annulus between the primary filter pack and the bentonite seal, and between the bentonite seal and the grout backfill. The secondary filter pack shall be uniformly graded fine sand with a 100 percent by weight passing the No. 30 U.S. Standard sieve, and less than 2 percent by weight passing the 200 U.S. Standard sieve. Blasting sand or "sugar" sand is typically used for this purpose. The purpose of the first secondary filter pack is to prevent the intrusion of bentonite grout seal into the primary filter pack. The purpose of the final secondary filter pack is to limit the migration of the grout material into the bentonite seal. Bentonite Seal (Plug) A seal shall be placed on top of the filter pack. This seal shall consist of a high solids, pure, bentonite material. Bentonite in either pellet or granular form is acceptable. The method of placing bentonite is by the tremie method. Pouring of the bentonite is acceptable in shallow boreholes [less than 50 feet (15 m)] where the annular space is large enough to prevent bridging and to allow measuring to insure that the bentonite has been placed at the proper intervals. The bentonite seal shall be placed above the filter pack to the designated depth or a minimum of at least 2 feet (0.6 m) above the filter pack. It is necessary to allow the bentonite to hydrate EDR-SOP-07 Page 5

142 before initiating the next backfilling operation (grouting). If for some reason, the water table is temporarily below the bentonite seal interval, potable water shall be used to hydrate the bentonite. Grouting The annular space between the well casing and the borehole wall shall be filled with either a neat cement grout or cement/bentonite grout or bentonite grout. The grout shall be placed into the borehole, using positive displacement techniques and the tremie method. The grout shall be placed from the top of the bentonite seal to within 2 feet (0.6 m) of the ground surface or below the frost line, whichever is greater. The grout shall be allowed to "set" for a minimum of 24 hours before the concrete surface pad is installed. Check grout level and regrout, if necessary. All grout shall be prepared in accordance with the manufacturer's specification. In cases where concrete surface pads are not used, the grout should be brought to within 6 to 12 inches of the ground surface with the remaining height to be backfilled to match the surrounding surface conditions (i.e., asphalt, topsoil, etc.). This method reduces surface water infiltration and well lifting due to frost conditions. Aboveground Riser Pipe and Outer Protective Casings The well casing, when installed and grouted, shall extend above the ground surface a minimum of 2.5 feet (0.75 m). A protective casing shall be installed over the completed well and grouted into place. The outer protective casing shall be of steel construction with a hinged, locking cap that is waterproof and tamper proof. The protective casing shall have sufficient clearance around the inner well casing, so that the outer protective casing will not come into contact with the inner well casing after installation. A concrete security collar shall be installed flush with the ground surface around the outer protective casing at a depth below the frost penetration. Typically a sonatube may be used to fill the concrete around the protective casing. The collar will be sloped to promote surface drainage away from the monitoring well. The protective casings shall have a minimum of two weep holes for drainage. These weep holes shall be a minimum 1/4 inch (6.4 mm) in diameter and drilled into the protective casing just above the top of the level of concrete inside to prevent standing water inside the protective casing. The weep holes will also allow internal air pressure to be in equilibrium with the atmospheric conditions. Dry bentonite pellets, granules, or chips shall be placed in the annular space below ground level within the protective casing. Coarse sand or pea gravel shall be placed in the annular space above the dry bentonite pellets and above the weep hole to prevent entry of insects. In cases where wells must be located in traffic areas, the wells will have to be flush-mount installations. For these wells, a waterproof protective casing is essential to ensure the integrity of the groundwater formation. The protective casings are grouted in place and are usually fitted with bolts and rubber gaskets. For flush-mount installations, the well tops are usually fitted with locking caps. Well caps shall be watertight screw-on connections as referenced in ASTM F-480. For at-grade completions, well caps shall provide a means of locking using a standard padlock. EDR-SOP-07 Page 6

143 For above-grade completions, the well cap or well casing shall be vented with a 1/4-inch (6.4 mm) drilled hole. Flush mount well installations are typically more problematic and maintenance intensive than above-grade installations and therefore should be avoided where possible. Protective Posts Protective posts, if required, shall consist of either Schedule 40, 4-inch diameter carbon steel pipe or 4-inch-by- 4-inch untreated wooden posts. The post shall be 5 feet (1.4 m) in overall length, and installed at least 3 feet (0.86 m) above grade. Up to four posts shall be provided for each monitoring well and they shall be installed in concrete separate from the concrete security collar. The posts shall be located at the corners of the concrete collar, 4 feet radially from the center of the monitoring well at 90-degree increments. Well Locations Well locations will primarily be selected in the Work Plan to provide a good geographical distribution across the site (given the site conditions anticipated) to suit the intended purpose of the study. Most often, the locations are not pre-verified to confirm clearance from underground or overhead utilities or to match the site's specific characteristics (i.e., traffic patterns, drainage patterns, etc.). Consequently, it is the Field Staff's task to select the exact location for each well consistent with all of the site and study requirements. If a well must be moved more than 20 feet (5.7 m) from the initially identified location, Field personnel must confirm the selected location's suitability with the Project Manager. To the extent practicable, wells should be located adjacent to permanent features (i.e., fences, buildings, etc.) that offer some form of protection and a reference point for locating the well. Wells located in high traffic areas or road allowance right of ways are undesirable and should be avoided if possible. Low lying areas are also undesirable. Field ties accurately identifying each well location must be taken, as soon as each well is completed, to insure that no confusion with other well installation occurs. CONSTRUCTION TECHNIQUIES Well Installation The borehole shall be drilled as close to vertical as possible. Slanted boreholes shall not be acceptable unless specified in the design. The well casings and the well screen shall be placed into the borehole and plumbed. Where critical, centralizers may be used to aid in the well installation. Another method of placing the casings and well screen into the borehole and plumbing it at the same time is to suspend the string of well casing and screen in the borehole by means of the wireline on the drill rig. No lubricating oils or grease shall be used on casing threads. Teflon tape may be used to wrap the threads to insure a tight fit and minimize leakage. No glue of any type shall be used to secure casing joints. Welded joint construction is also acceptable. Before the casing and well screen are placed on the bottom of the borehole, at EDR-SOP-07 Page 7

144 least 6 inches (15 cm) of filter material shall be placed at the bottom to serve as a footing (an exception may occur if PL is being monitored). The well shall be placed, plumb, into the borehole. Centralizers may be used to plumb a well, but they shall be placed so that the placement of the filter pack, bentonite seal, and annular grout will not be hindered. Monitoring wells less than 50 feet (15 m) deep do not require centralizers. If centralizers are to be used, they shall be placed below the well screen and above the bentonite seal. When installing the monitoring well through hollow-stem augers, the augers shall be slowly pulled back as the filter pack, bentonite seal, and grout are tremied and/or poured into place. Once the monitoring well is in place, the filter pack shall be placed around the screen up to the designated depth. When the filter pack has been installed, the bentonite seal shall be placed directly on top of the filter pack up to the designated depth or a minimum of 2 feet (0.6 m) above the filter pack. The bentonite seal shall be allowed to hydrate for a reasonable amount of time. Usually, 30 minutes is sufficient. Once the bentonite seal has hydrated, the grout shall then be pumped by the tremie method into the annular space around the casing up to within 2 feet (0.6 m) of ground surface or below the frost line, whichever is greater [6 to 12 inches (0.16 to 0.3 m) in cases where concrete caps are not being used]. The end of the grout pipe should always be submerged in the grout to ensure positive displacement. The grout shall be allowed to set for a minimum of 24 hours before the concrete surface seal is installed. Check grout level and regrout, if necessary. After the wells have been installed, the protective casings shall be permanently marked with the well number on the cover or inside. If the monitoring wells are installed in a traffic area (such as a parking lot), in a residential yard, or along a road, it may be required to install a flush-mounted protective casing that is watertight. Flush-mount casings are designed to extend from the ground surface down into the concrete plug around the well casing. The immediate areas around flush-mount well installations shall be elevated to the extent practicable above surrounding areas to minimize standing water and promote runoff. It is to be noted that the selection of well locations prior to drilling should always avoid low areas that are subject to surface water ponding. Double-Cased Wells Double cased wells shall be constructed when there is reason to believe that interconnection of two aquifers by well construction may cause cross contamination. A pilot boring shall be bored through the overburden and/ or the contaminated zone into a confining layer (clay) or bedrock. An outer casing (sometimes called surface casing) shall then be placed into the borehole and grouted. The borehole and outer casing shall extend into the upper layer of the confining layer. The depth of penetration will depend upon the thickness of the confining layer but usually only a few feet are needed. In the case of bedrock, drilling can stop at the top of competent bedrock. The size of the outer casing shall be of sufficient inside diameter (ID) to contain the inner casing and the 2-inch (5 cm) minimum annular space. The outer casing shall be grouted either by the tremie method or by pressure grouting to within 2 feet (0.6 m) of the ground surface. The grout shall be pumped into the annular space between the outer casing and the borehole EDR-SOP-07 Page 8

145 wall. A minimum of 24 hours shall be allowed for the grout to "set" or cure before attempting to drill through it. The grout mixture used to seal the outer annular space may be either a neat cement or cement/bentonite. When drilling through the seal, care shall be taken to avoiding cracking, shattering, and/or washing out of the seal. The two most commonly used casing installation techniques are described in the following: Immersion Method Drill borehole; Fill borehole with grout; Insert casing that has bottom end plugged with grout (previously placed and set) into borehole (water may be added inside casing to overcome buoyancy); and Tap casing into confining layer or bedrock. Pumping Method Drill borehole; Insert casing into borehole; Insert grout pumping tube and inflatable packer into casing; Inflate packer (with grout pumping tube extending through center of packer); Pump grout through packer until grout return is noted at surface from around outside of casing; Tap casing into confining layer or bedrock; and Remove packer and grout tube. Bedrock Wells The installation of monitoring wells into bedrock may be accomplished in two ways: a) The first method is to drill a pilot borehole through the overburden into the bedrock. An outer casing is then installed into the borehole by setting it into the bedrock and grouting it into place as described in the previous section. After the grout has set, the borehole may then be advanced through the grout seal into the bedrock. The borehole is typically advanced into the bedrock by the rock coring method. Rock coring makes a smooth, round hole through the seal and into the bedrock without cracking and/ or shattering the seal. Roller cone bits are commonly used in soft bedrock, but caution shall be used when advancing through the grout seal due to excessive water and "down" pressure which may cause cracking and/or shattering of the seal. The advantages of the coring technique are that it provides a continuous core of the rock penetration, allowing for proper formation and fracture identification and providing a sample for the geologic record. When the drilling is complete, the finished well consists of an open borehole from the casing end to the bottom of the well. There is no inner casing. The open rock interval serves as the monitoring zone. The outer casing installed down into bedrock extends above ground surface and can also serve as the protective casing. If the protective casing becomes cracked or is sheared off at the ground surface, the well is open to any contamination from the ground surface and will have to be repaired immediately or abandoned. It may be more desirable to install a protective casing over the outer casing as an extra precaution. EDR-SOP-07 Page 9

146 For wells installed to monitor bedrock units below the uppermost layers, a second casing would be installed to the top of the desired monitoring interval. Thereafter, the borehole would be extended through the casings into the bedrock interval selected to be monitored. b) The second method of installing a monitoring well into bedrock is to install the outer casing and drill the borehole into the bedrock, and then install an inner casing and well screen and backfill with the filter pack, bentonite plug, and grout. This well installation method enables isolation of the monitoring zone after the hole has been drilled. This method may also be needed in cases where the bedrock continually collapses into the open corehole. Well Development Prior to the collection of hydraulic or groundwater quality data, a monitoring well must be developed. The objective of the monitoring well development is to repair the damage done to the formation (unconsolidated or consolidated) by the drilling operation so that the natural hydraulic properties of the water bearing formation are restored. The three most suitable methods for well development are: 1. Surge block surging; 2. Pumping / overpumping / backwashing; 3. Bailing; and 4. Combinations of above three methods. Surge Block Surge blocks can be used effectively to destroy the bridging of the fine formation particles and to create the agitation that is necessary to develop a monitoring well. A surge block is used alternatively with either a bailer or pump so that material that has been agitated and loosened by the surging action is removed. The surge block assembly must be of sufficient weight to free fall through the water in the well and create a vigorous outward surge. Surging begins at the top of the well intake so that sand or silt loosened by the initial surging action cannot cascade down on top of the surge block and prevent removal of the surge block from the well. Surging is initially gentle, and the energy of the action is increased during the development process. A combination of surging and pumping should continue until the water is free from suspended particulate matter. Pumping / Overpumping / Backwashing The easiest, least expensive, and most commonly employed technique of monitoring well development is some form of pumping. Over pumping causes an increase in the flow velocity of the water to the well intake and creates a rapid and effective migration of particulates toward the well. Where there is no backflow prevention valve (check valve) installed, the pump can be alternately started and stopped. This backwashing produces a surging action in the well and tends to loosen the bridging of the fine particles in the formation. Backwashing can only be performed using dedicated pumps and hoses or those that EDR-SOP-07 Page 10

147 have been cleaned prior to use at the well being developed. The types of pumps commonly used for well development are; a BK pump, a Grundfos submersible pump, or a Red-jacket submersible pump, etc. All of the above techniques are designed to remove the drilling effects from the monitored zone, and insofar as possible, to restore the formations penetrated to indigenous conditions. The above development techniques avoid the use of introduced fluids (including air) into the monitored zone during the development process. This not only minimizes adverse impacts on the quality of water samples, but also restricts development options that would otherwise be available. a) Development of Overburden Wells Any of the development techniques described above can be used to develop monitoring wells installed in relatively permeable formations. However, in formations that have low hydraulic conductivity, none of the preceding well development methods are completely satisfactory. b) Development of Bedrock Wells All drilling methods produce some plugging of fractures. Any material that causes sealing of water bearing fractures as a result of the drilling activities must be removed by a development procedure. Any of the development methods described above can be used to develop wells installed in bedrock. Surging is often needed to obtain maximum efficiency of bedrock wells. In relatively clean, permeable formations where water flows freely into the well, bailing is an effective development technique. The bailer is allowed to fall freely through the monitoring well until it strikes the surface of the water. The contact of the bailer produces a strong outward surge of water. This tends to break up bridging that has developed within the formation. As the bailer fills and is rapidly withdrawn, the drawdown created in the borehole causes the particulate matter outside the well intake to flow through the well intake and into the well. Subsequent bailing removes the sand and other particulate matter from the well. Bailing should be continued until the water is free from suspended particulate matter. DESIGN CONSIDERATIONS Well Diameter The diameter of the well installed is primarily dictated by the purpose of the installation. In general, wells installed for groundwater monitoring purposes should be at least 2 inches (5 cm) in diameter. This allows small diameter bladder pumps to be installed for sampling (as well as allowing for small diameter bailers and suction tubes). Wells of smaller diameter should be avoided unless they are solely used for hydraulic monitoring (cost saving between 1-inch and 2-inch (2.5 and 5.0 cm) diameter is negligible in comparison to the cost of the installation). EDR-SOP-07 Page 11

148 For groundwater extraction wells, a 4-inch (10 cm) diameter well should be the minimum size considered. This will allow a reasonable sized submersible pump to be installed and operated. Screen Length and Placement The screen length should be consistent with the desired monitored interval and geologic conditions encountered. A 5- to 10-foot (1.5 to 3.0 m) screen length is generally sufficient when the screen is completely submerged and monitoring of an isolated zone is desired. However, in some cases it is necessary to screen the entire monitored interval. In cases where the water table is being monitored (i.e., PL), a 15- to 20-foot (4.3 to 5.7 m) screen length is preferred to accommodate seasonal fluctuations of the water table. A 5- to 10-foot (1.5 to 3.0 m) screen length is adequate where the formation into which the well is being installed is of a low enough hydraulic conductivity to allow the water level to be drawn down during sampling through the filter pack and into the screened interval. This will allow any floating layer to be drawn into the well when the water level is depressed for sampling. Dense PL (DPL), if present, should be easily detectable since the well screen may be set on the bottom of the borehole and should be located at the top of some form of confining layer. As long as the screen material is more permeable than the surrounding geologic strata, a 5- to 10-foot (1.5 to 3.0 m) filter pack length should suffice. If the formation is more permeable and the potential for Light PL (LPL) presence exists, a longer screen length may be necessary. Well Slot Size / Filter Pack Material The slot size of the well screen must be sized to match the filter pack material. The filter pack material must be sized to match the geologic strata. Well Materials The materials selected for well construction must be compatible with the chemicals anticipated to be present in the groundwater and parameter groups selected for chemical analysis. The following well materials are often used: Stainless steel well screen and riser pipe; Stainless steel well screen and black steel riser pipe; and PVC well screen and riser pipe. Note: PVC should not be used where solvents are present, nor should solvent cement be used to join PVC sections of pipe together. EDR-SOP-07 Page 12

149 WELL INSTALLATION DOCUMENTATION Details of each overburden well installation may be recorded on the Borehole Log and other pertinent information recorded within the field book. The soil stratigraphy encountered at each well location must be recorded in accordance with Pinchin s standards. The field book records and sketches of bedrock well installations must note: Corehole diameter, depth, and lengths; Casing diameter, depth, materials, and lengths; Overburden depth; Grout placement; Surface cap details; Date of installation; and Development record. Each well installed must have accurate field ties to the center of the well from three adjacent permanent features. Development records must be documented in the field notes. Each well must be permanently marked to identify the well number designation. FOLLOW-UP ACTIVITIES Once the monitoring wells have been completed and developed, the following activities need to be done: All field logs shall be submitted to the Project Manager, who will designate who is responsible for the generation of the final well log; Well/boring locations plotted onto the site plan, since boring locations may be changed in the field due to underground/ overhead interferences or other conditions; Arrange surveyor to obtain accurate horizontal and vertical control (where applicable based on discussions with the Project Manager; Tabulate monitoring well details; and A summary write-up on field activities including, but not necessarily limited to such items as drilling method(s), well construction material, site geology and well development shall be documented as outlined in the brief / de-brief SOP.

154 SCOPE AND APPLICATION This SOP defines the standard procedures for collecting groundwater samples and provides descriptions of equipment, field procedures and Quality Assurance/Quality Control (QA/QC) procedures necessary to collect groundwater samples (prior to sampling see Well Development SOP 17 to ensure the well has been developed). Be sure to review the sampling work plan or sampling and analysis plan before sampling to ensure the proper samples are collected (including QA/QC samples). EQUIPMENT AND REAGENTS REQUIRED Water Level Measurements Water level tape and/or interface probe Field Book Distilled water and bucket Non-phosphate soap Bailer Jerry Can Traffic Control Equipment (if needed) Notes: Water level measurements are taken with a water level meter and/or interface probe (battery needed). Petroleum Hydrocarbons ( LPH ) measurements are taken with a battery run interface probe. Prior to leaving the office the meter(s) should be tested to ensure that they are working. A light will turn on, or the meter will beep when the instrument is turned on and the probe(s) contacts water and/or LPH. It is possible that a portion of the tape has been removed near the probe due to repairs. Repaired tapes will be labeled, with the adjustments to the length (i.e. Depth -0.1 m). The tape should be examined to determine whether the tape s length has been altered so that the depth measurements can be adjusted to reflect true depth. Groundwater Sampling Well Keys Water level probe measured in 0.1 cm increments Oil-water interface probe Assorted tools (knife, screwdriver, etc.) Foot valve/polyethylene tubing/waterra hand pump Disposable polyethylene or stainless steel bailer/nylon Rope or wire Distilled Water EDR-SOP-08 Page 1

155 Polyethylene or glass container (field parameter measurements) Paper towels to Kimwipes Calculator Field forms and Field notebook Waterproof and permanent marker Appropriate health and safety equipment Disposable gloves Equipment which may be used during well sampling, in addition to the above: Thermometer/pH meter (with automatic temperature compensation) / Conductivity meter / Calibration fluids, when required Disposable field filtration units / filters (if appropriate) Cooler and ice packs Sample jars and labels. Sample bottles with preservations added should be obtained from the analytical laboratory. Several extra sample bottles should be available in case of breakage or other problems Laboratory Chain of Custody Forms PROCEDURES Equipment Decontamination Before any purging or sampling begins, all well probes, foot valves, bailers, and other sampling devices shall be decontaminated. If dedicated equipment is used, it should be rinsed with distilled water. Each piece of purging or sampling equipment shall also be decontaminated between each well. Used solutions will be disposed of with purged well water. If dedicated equipment is not being used, purging/sampling should start at the least contaminated well (based on field observations or historical laboratory data). Decontaminate procedures need to be completed between each sampling location. Instrument Calibration Electronic equipment which may be used during sampling includes a ph meter with temperature scale and automatic temperature compensation, a conductivity meter, and water level and LPH interface probe. Before going into the field, the sampler shall verify that these instruments are operating properly. The ph and conductivity meters require calibration prior to use and must be recalibrated if the instrument has been turned off between measurement events at a sample station. Calibration times and readings should be recorded in the field notebook. Specific instructions for calibrating the instruments are provided with the equipment. EDR-SOP-08 Page 2

156 Well Purging The purpose of well purging is to remove stagnant water from the well and filter media, and obtain representative water from the geologic formation being sampled while minimizing disturbance to the collected samples. Evacuated well water shall be typically disposed of at ground surface in the area of the well following screening with a Gastechtor or an organic vapour meter. If separate phase liquid is present or elevated VOCs are detected, the purge water will be contained for subsequent disposal. The following steps should be taken to purge each well: The well number shall be confirmed. The condition of the groundwater monitoring well and any unusual conditions in the area around the well will be noted in the field logbook. The well will be opened. Readings will be taken with a Gastechtor or an organic vapour meter, if appropriate. The depth of static water level will be measured (to nearest 1 mm) and recorded from the top of casing ( TOC ) measuring point on the well riser. The presence of light non-aqueous phase liquids (LPL) will be determined with the oil-water interface probe and/or bailer. If LPL is identified for the first time, its thickness will be measured and a sample of the LPL will be collected with a bailer, if required by the Project Manager (PM). If elevated vapours are measured, the presence/absence of LPL is to be confirmed with a bailer. If LPL is detected in a well, the groundwater is typically not sampled, unless instructed by the PM. If the presence of dense PL (DPL) is suspected, it will be determined by slowly lowering a clear, double check valve PVC bailer or comparable device to the bottom of the well screen and obtaining a sample for visual inspection. If DPL is observed, a sample will be collected if required by the PM by slowly draining the water (if present) from the bailer until the DPL layer is reached. The total depth of the well from the same measuring point on the PVC riser will be measured and recorded, if required by the PM. The volume of water (in litres) in the will be calculated if required by the PM, based on the height of the water in the well, the PVC diameter, and the borehole diameter. The following formula should be used, depending on the parameters: Well Volume (litres) = [Well Depth (m) Depth to Water (m)] x C where C= 9.0 litres/m 50 mm diameter well and 180 mm diameter borehole (hollow stem auger) The minimum volume to be purged from the well is three times the Well Volume. Three Well Volumes of water will be evacuated with a bailer, Waterra hand pump, Waterra foot valve or submersible pump. EDR-SOP-08 Page 3

157 or If the well is bailed dry during evacuation, it will be assumed that the purpose of the purging has been accomplished and that all stagnant water within the well has been removed. EDR-SOP-08 Page 4

158 Sample Collection Samples for chemical analysis will be collected within 8 hours of purging. For slow recovering wells, the sample shall be collected after a sufficient volume is available. The water samples shall be taken from within the well screen interval for shallow wells. In deeper wells, this is not an issue and samples can be collected from the upper portion of the well. The following sampling procedure is to be used at each well: 1. Decontaminated sampling equipment will be assembled. If applicable, new nylon rope or wire will be used for each well for each sampling event if using a bailer. 2. Identification labels for sample bottles will be filled out for each well. 3. The foot valve and dedicated polyethylene tubing, or bailer will be lowered slowly and gently into contact with the water in the well. 4. If a foot valve and polyethylene tubing is used for sampling, a steady constant motion should be used until water flows smoothly from the tubing. Alternatively, if a bailer is used, it will be retrieved smoothly and the water will be slowly drained into the sample containers from the bailer. 5. The individual sample bottles should be filled in the order given below: Volatile organic compounds (VOCs) which include BTEX Semi-volatile organic compounds (which include PAHs), pesticides and PCBs, and dioxins and furans Petroleum Hydrocarbons Cyanide and sulfide Nitrates and nitrites Sulfate, chloride, alkalinity and total dissolved solids VOC sample vials should be completely filled so the water forms a convex meniscus at the top of the vial, thus when capped no air space should exist in the vial. Turn the vial over and tap it to check for bubbles in the vial, which indicated air space. If air bubbles are observed in the sample vial repeat the procedure. Sample bottles for metals should be filled so that no head space is left in the bottle. 6. Sample for metals, if required by the PM, will be field filtered using 0.45 micron filter paper. 7. The PVC cap will be replaced and the well locked, if applicable. 8. Documentation of field activities in the field notebook, field forms, and the Chain-of-Custody Form will be completed. Field Quality Assurance / Quality Control Procedures and Samples The well sampling order will be dependent on expected levels of contamination in each well, if known, and will be determined prior to sampling through discussion with the PM. Sampling will progress from the least EDR-SOP-08 Page 5

159 contaminated well to the most contaminated well. QA/QC samples may be collected during groundwater sampling. Field QA/QC samples are designed to help identify potential sources of external sample contamination and evaluate potential error introduced by sample collection and handling. The need for any type of QA/QC samples will be determined by the PM. The samples will we assigned an identification number, stored in an iced cooler, and shipped to the laboratory with the other samples. QA/QC samples may consist of one or more of the following: A trip blank is a bottle of clean distilled water which is brought to the field (never opened) and shipped to the lab with the other samples. One trip blank should be sent with each cooler containing water samples to be analysed for VOCs. A duplicate sample will be collected at the same time as the initial sample. The initial sample bottle for a particular parameter or set of parameters will be filled first, then duplicate sample bottles for the same parameter(s), and so on until all necessary sample bottles for both the initial sample and the duplicate sample have been filled. Quality Records Upon completion of the sampling event, the Field notebooks should be photocopied and submitted to the PM for review. The information can include: Samples collected Field Supervisor and company affiliation Weather conditions Condition of the well Calculations (e.g. calculation of purged volume) Analyses that will be performed by the laboratory Water Level Measurements Water level measurements should be taken relative to the TOC riser, and documented on the field monitoring sheets. The TOC and the top of ground surface should be surveyed relative to a geodetic marker or a site specific benchmark. The water level measurements should be correlated to the benchmark elevation, if required by the Project Manager. LPH Encountered LPH level measurements should be taken relative to the TOC using electronic interface probe and documented. This instrument will emit a continuous beep when in contact with LPH and an intermittent beep when in contact with water. If LPH or elevated vapour concentrations are encountered during monitoring a bailer should be EDR-SOP-08 Page 6

160 used to verify the presence and thickness of the LPH. The bailer should be lowered so that it intersects the ground water/lph interface. The thickness of the LPH within the bailer is then measured and recorded. It is critical that any equipment that comes into contact with the free product is thoroughly de-contaminated before being introduced to a different well, this is especially true when a sampling program is also within the scope of the job. TRAINING AND RESPONSIBILITY The Operations Manager is responsible for identifying the initial training needs of the EDR Department staff and ensuring that staff is trained and competent before undertaking work assignments. All trained personnel are responsible for identifying coaching or re-training needs (if they are uncomfortable with work assignments that have been assigned). PRECAUTIONS Samples used for field screening shall not be used for other analyses. The careful application of Health & Safety Training by each employee is an integral part of all activities and is assumed as part of this SOP.

164 SCOPE AND APPLICATION This SOP presents general requirements of field decontamination. EQUIPMENT AND REAGENTS REQUIRED The following is a list of equipment that may be needed to perform decontamination: Brushes Wash tubs Buckets Scrapers, flat bladed Hot water high-pressure sprayer Disposal drums (205 litre with secure lids) Sponges or paper towels Detergent (non-phosphate) Distilled or potable tap water Garden-type water sprayers Spray bottles Methanol/methyl hydrate (if necessary) Manufacturer s Manual(s) Clean stainless steel or plastic pan Camera Ziploc bags Personal Protective Equipment Photo ionization detector (PID) or flame ionization detector (FID) PROCEDURES Personnel The decontamination procedure for field personnel, if deemed necessary by Project Manager, shall include one or more of the following steps, and will be carried out in the order presented: Glove and rubber boot wash in a detergent solution Glove and rubber boot rinse Scraping soil from non-rubber boots Duct tape removal, if appropriate EDR-SOP-07 Page 1

165 Outer glove removal Coverall removal Respirator removal (if used) Inner glove removal (if used) Sampling Equipment The following steps will be used to decontaminate sampling equipment: Personnel will dress in suitable Personal Protective Equipment (PPE) to reduce personal exposure. Gross contamination on equipment will be scraped off at the sampling or investigation site. Equipment that will not be damaged by water will be placed in a wash tub containing a low-sudsing detergent along with potable water and scrubbed with a bristle brush or similar utensil. Equipment will be rinsed with tap water in a second wash tub, followed by a potable water rinse. Equipment that will not be damaged by solvents will be sprayed or rinse with methanol, methyl hydrate or equivalent product, if required by the Project Manager (PM). The equipment will then be rinsed with potable water, wiped and allowed to air dry. Soil sampling equipment that comes into direct contact with the sample (i.e. split spoons, stainless steel trowels and spoons) will be cleaned with methanol/methyl hydrate or non-phosphate detergent as specified by the PM. Unless dedicated, foot valves used for groundwater sampling will also be cleaned with methanol/methyl hydrate and rinsed with potable water, if required by the PM. Equipment that may be damaged by water will be carefully wiped clean using a sponge first rinsed in detergent water, then rinsed with potable water. Care will be taken to prevent any equipment damage. Rinse and detergent water will be replaced with new solutions between borings or sample locations or as required based on the judgement of the Project Manager. Following decontamination, equipment will be placed in a clean area or on clean plastic sheeting to prevent contact with potentially contaminated soil. Drilling and Heavy Equipment The following steps may be used to decontaminate drilling and heavy equipment, if required by the PM; Personnel will dress in suitable PPE to reduce personal exposure. Equipment showing gross contamination or having caked-on drill cuttings will be scraped with a flatbladed scraper (or equivalent) at the sampling or investigation Site. Equipment that will not be damaged by water, such as a drill rig, auger, drill bits, and shovels will be sprayed with a hot water, high-pressure washer, then rinsed with potable water, if required by the PM. Care will be taken to adequately clean the insides of the hollow-stem augers and backhoe or excavation buckets. Following decontamination, drilling equipment will be placed on clean drill rig and moved to a clean area. EDR-SOP-07 Page 2

166 WASTEWATER Liquid waste water from decontamination activities, monitoring well development and purging and rinse water are considered to represent sources of contamination which are substantially reduced from existing on-site sources. Disposal of wastewater will be determined on site specific bases. Wastewater containing separate phase liquids (e.g. LPL, DLPL or visibly contaminated water) will be contained for subsequent disposal. Questions regarding disposal of wastewater will be resolved by the Project Manager. OTHER WASTES Solid wastes from heavy equipment decontamination, drilling cuttings or test pit activities with evident contamination will be tarped or containerized. This material will be placed in an on-site refuse bin for subsequent off-site disposal at the local solid waste disposal facility or other facility designated by the Project Manager. Other solid wastes, such as used personal protective clothing, water sample filter, and spent sampling materials will be containerized. This material will be placed in an on-site refuse bin for subsequent off-site disposal at the local solid waste disposal facility or other facility designated by the Project Manager. QUALITY ASSURANCE REQUIREMENTS Equipment rinsate samples may be taken of the decontaminated sampling equipment as directed by the Project Manager, to verify the effectiveness of the decontamination procedures. The rinsate procedure will include rinsing potable water through or over a decontaminated sampling tool (e.g. a split spoon sampler or bailer) and collecting the rinsate water in sample bottles, which will be sent to the laboratory for analysis. The rinsate, including the sample number and time relative to other soil and/or groundwater samples, will be recorded in field notebook. QUALITY RECORDS Sampling personnel will be responsible for documenting the decontamination of sampling and drilling equipment. The documentation will be recorded in the site Supervisor s field notebook. EDR-SOP-07 Page 3

171 SCOPE AND APPLICATION This SOP defines the standard procedures for measuring water quality indicators collected during water sampling. This procedure covers the calibration and use of multi-parameter and single-parameter probes (datasondes) for monitoring in-situ water quality in streams, down hole monitoring well, flow-through cells and unattended data logging. In-situ water parameters may include temperature, ph, dissolved oxygen ( DO ), oxidation reduction potential ( ORP ), conductivity and turbidity. EQUIPMENT AND REAGENTS REQUIRED Single or multi-parameter probe for monitoring in-situ parameters Calibration solutions for calibrating the instruments to the standard values Water level tape and/or interface probe Field Book Distilled water and bucket Non-phosphate soap PROCEDURES Instrument Measurement Accuracy The instrument being utilized for measuring water quality parameters shall be capable of producing measurement accuracy greater or equal to the following specifications: Temperature: ± 0.5 o C Conductivity: ± 1µS/cm ph: ±0.5 ph Dissolved Oxygen: ±0.2 mg/l 20 mg/l ± 0.6 mg/l > 20 mg/l % Saturation: ±2% air saturation Turbidity: ±1% up to 100 NTU ±3% up to NTU ±5% up to NTU ORP: ± 20 mv EDR-SOP-16 Page 1

172 Instrument Calibration Prior to and after the use, equipment shall be maintained and calibrated according to user manuals, and/or manufacturer specifications at a frequency recommended by or exceeded the manufacturer. All equipment manuals shall be kept on file, or in a established location. Individual log books should be maintained for each piece of equipment requiring regular maintenance and calibration; or at a minimum, each piece of equipment should be recorded with serial number or unique identifying number in a calibration log book. All dates, lot numbers, notes and calculations related to maintenance and calibrations should be recorded in log book. The ph and conductivity meters require calibration prior to use and must be recalibrated if the instrument has been turned off between measurement events at a sample station. Extra care must be taken to calibrate multi-parameter sonde to prevent cross-contamination. Specifically, following immersion of the sonde probes into each calibration standard, all probes should be thoroughly rinsed in distilled or de-ionized water and the excess water shaken off or blotted dry with a lint-free wipe. Conductivity standards are much more sensitive to cross contamination/dilution than other standards; therefore, prior to immersion in a conductivity standard, all probes should be thoroughly rinsed and completely dried with lint-free wipes or compressed air. Besides being easily diluted, conductivity also affects other parameters (specifically DO), therefore conductivity should always be the first parameter calibrated. The EPA (USEPA, 2007) recommends the following order for calibration of a multi-parameter probe: 1. Specific Conductance or Conductivity 2. ph 3. DO 4. Turbidity There is no recommended order for calibration of other parameters. Single-parameter Probes Prior to conducting field measurements, sensors must be allowed to equilibrate to the temperature of water being monitored. Sensors have equilibrated adequately when temperature reading has stabilized. Deployment of single-parameter probes will follow the following procedures: Temperature Whenever possible the temperature shall be measure in-stream of the media (i.e. flowing stream, direct deployment in monitoring well) being measured. When temperature cannot be measured in-stream, it can be measured in beaker or a bucket. The following conditions must be met when measure temperature from beaker or bucket. EDR-SOP-16 Page 2

173 The apparatus shall be large enough to allow full immersion of the temperature probe. The apparatus is to be rinsed with water being tested prior to collecting sample. The probe must be placed in the apparatus immediately before the temperature changes. The apparatus must be shaded from direct sunlight and strong breezes before and during temperature measurement. The probe must be allowed to equilibrate for at least 1 minute before temperature is recorded. ph Preferably, ph is measured directly in-stream at centroid of flow and at mid-depth. Allow ph probe to equilibrate according to manufacturer s recommendations before ph is recorded to the nearest 0.01 standard unit without removing from the water. If the ph cannot be measured in-stream, it should be measured in an apparatus (i.e. bucket or beaker) using the precautions outlined in the Temperature section. Dissolved Oxygen DO is normally measured with DO meter, preferably at the centroid of flow and at mid-depth. The DO probe must equilibrate according to manufacturer s recommendations before DO is recorded. Some types of probes require sufficient flow of fresh water across the membrane to maintain accuracy and precision of DO analysis. If DO cannot be measured in-stream, it can be measured in an apparatus using the precautions outlined in the Temperature section. When taking DO measurements in an apparatus, either turn on the stirrer, if equipped, or physically move the probe in a gentle motion. This is also applicable to the deployment of DO probe in the down hole monitoring well. ORP The ORP shall be measured similar to the instructions provided in the ph section. In addition, temperature affects the stability of the ORP therefore readings should be taken before temperature can fluctuate. Turbidity In-situ turbidity samples are analyzed in the field using portable turbidity meter. Sample aliquots should be well mixed and portioned from the bulk parameters sample bottle or other unpreserved sample bottle. Manufacturer s procedure for the measurements shall be followed. Single or Multi-parameter Probe Use In Flow Through Cell For groundwater sample collections using a low-flow sampling technique, the following parameters must be measured in order to determine when wells stability has been achieved prior to sampling. The parameters being measured and their respective measurements must fall within the stated range for three consecutive readings. If the anticipated third reading of any individual parameter does not fall within the stated range, then process to achieve three consecutive readings for that parameter must be restarted. If, after four hours, stability has not been achieved for the parameters listed below, follow the guidelines in the sub-section Purge Volume vs. Stabilization Time. The following procedure shall be followed during the measurement using a multiparameter probe. EDR-SOP-16 Page 3

174 Water Level Drawdown <0.3 ft* ph ±0.1 unit Specific Conductance ±3% Temperature ±3% Dissolved Oxygen ±10% ORP ±10 mv Turbidity ±10% for values greater than 1 NTU *During pump start-up, drawdown may exceed the m (0.3 ft) target and then recover as flow-rate adjustments are made. In wells with short screens (i.e. 5 to 10 ft long) or when sampling for PHCs at the water table, it is much more important to limit the drawdown to less than m (0.3 ft). Measurements should be taken every 5 to 6 minutes. However, this interval is based upon the time it takes for purge water to replace one flow-through-cell volume (250 ml) and the time it takes to measure and record the data. If purge rate decreases or if the flow cell volume is increased, the time required for purge water replacement will increase. Similarly, if the flow cell volume decreases the time required for purge water replacement will decrease. Purge Volume vs. Stabilization Time In some cases, it may take considerable time to achieve stabilization of the water quality parameters. In other cases, they may never stabilize. However, as provided in USEPA guidance, the following options are available if stability has not been achieved after four hours of purging: continue purging until stabilization occurs, no matter how long it takes; discontinue purging, do not collect a sample and document the attempts to reach stabilization; discontinue purging, collect a sample and document the attempts to reach stabilization In situations where parameters do not stabilize, the sampler must document that low-flow purging and sampling could not be performed and document in the report how the samples were collected. While every effort should be taken to assure that all of the parameter stabilizes prior to sample collection, one should keep in mind that stabilization of some parameters may be more difficult to achieve than others. Also achieving stabilization of some parameters may be more important with respect to some contaminant types (e.g. metals vs. VOCs) than others. In addition, collection of accurate data aids in the evaluation of remediation technique being considered or implemented. For example, accurate DO measurements can aide whether groundwater is aerobic or anaerobic and thus helps determining whether monitored natural attenuation is a viable option for that particular site.

178 SCOPE AND APPLICATION This SOP presents a description of the methods generally employed for the collection of surface and subsurface. Soil samples may be recovered from boreholes advanced either by direct-push drilling methods or split-spoon samplers using hollow or solid stem augers or from a stockpile. PRIOR PLANNING AND PREPARATION The following activities must be undertaken prior to undertaking a soil sampling program. i) Review the sampling and analysis plan, work program, project documents, and the health and safety requirements with the Project Manager (as per the brief-de / de-brief SOP). ii) iii) iv) Complete an equipment requisition form. Assemble all equipment and supplies. Obtain a site plan and any previous stratigraphic logs. Determine the exact number and location of boreholes to be installed and the depths of samples for chemical analysis. Contact the selected laboratory to arrange/determine: o Laboratory; o Glassware/ sample jars; o Cooler; o Shipping details; o Turnaround time; o Start date; and o Expected duration. v) Establish borehole locations in field using available landmark or by surveying methods if necessary. vi) vii) Arrange for utility clearance of franchised utilities and site utilities. Determine notification needs with the Project Manager. Have the regulatory groups, Client, landowner, Pinchin personnel, and laboratory been informed of the sampling event? viii) Determine the methods for handling and disposal of drill cuttings, wash waters, and spent decontamination fluids. PROCEDURES Once the prior planning and preparation activities are completed, the soil sampling program can proceed. Checklists for soil sampling activities are included in the Phase II Forms directory of the Pinchin EMS Drive (S:\Phase II Field Forms). The following typical series of events which takes place is listed below. However, since the collection of samples is very project- and contaminant-specific, this may be altered to accommodate certain requirements: Determine the exact location where a soil sample is to occur; EDR-SOP-19 Page 1

179 Bring necessary equipment and supplies to where the sample will be collected; Make any necessary observations required at this time. (i.e. location of sampling point, GPS or grid coordinates the appearance of ground surface, date, time, etc.); Confirm that the sampling location is the correct one; Prepare sample jars to be used, confirm that they are the right type, that sufficient sample will be collected, and that the sample IDs correspond with the sampling location; Use appropriate gloves (i.e. dedicated nitrile gloves for each sample); Confirm that the sampling equipment (corer, trowel, putty knife, etc.) is clean as per the decontamination procedures; Carryout whatever work is required to remove soil from the ground (i.e. drilling hole or digging test pit); Carry out field screening and measurement of field parameters, if necessary; Record readings and make observations about soil properties as required (discussed in further detail in subsequent sections); Replace gloves (if necessary); Inspect jars and confirm that they are clean, intact, and correct for the parameters to be analyzed; Collect sample in appropriate sampling jars. Combine soils at this point if collecting composite sample. Minimize headspace for VOC and semi-volatiles samples. Follow any additional sampling requirements as requested by the laboratory; Confirm that the sample IDs are correct on the sample containers and bags, record the time that the sample was collected on the sample jars; For glass sample jars, place jars in appropriate cooler with protective packing (i.e. bubble rap and foam) and ice or dry ice as per sampling and analysis plan; Record the time that samples were collected as well as the type of samples that were collected; Dispose of excess soil and other waste materials as per project work plan; Fill in hole, or if it must remain open, take appropriate protective measures (i.e. place a rigid object such as a piece of wood over the open hole and place a safety cone over top); and Continue on to the next sample. Sample Collection From a Sampler Advanced Via Drilling Rig The boring is advanced incrementally to permit intermittent or continuous sampling. Test intervals and locations are normally stipulated by the project engineer or geologist. Typically, the depth interval for sampling is 2.5 to 5 feet [0.75 to 1.5 m] or less in homogeneous strata with at least one test and sampling location at every change of strata. In some cases, samples are taken continuously. When conducting environmental sampling, always change gloves between collecting subsequent soil samples to prevent cross-contamination. All tools (e.g., samplers, spatulas, etc.) must be field cleaned prior to use on each sample. For SOPs regarding drilling methods, please refer to the Borehole Drilling SOP, found in the Pinchin EMS Drive labeled EDR-SOP-06 Borehole Drilling. EDR-SOP-19 Page 2

180 Direct Push Sampling and Testing Procedure This method is used to obtain representative samples of the subsurface materials. The soil sampler is driven a total depth of 1.5 m during each sampling event. In some instances (with dense soil types) the sampler is only driven at 0.75 m intervals to provide a more representative sample. The soil sampler is then recovered from the borehole and brought to the surface, where the drillers helper retrieves the PVC sample liner and provides it to Pinchin personnel for logging and sampling. The driller s helper will cut the PVC sample liner using a special cutting tool and will advise Pinchin personnel with the following information: The total length in which the sampler was driven; At what depth the sample was obtained from; and Which is the top and which is the bottom of the sampler. Once the drillers helper has provided this information and the PVC sampler liner has be cut open, the sample liner is transferred to the geologist / engineer work surface. Note: A table made out of two sawhorses and a piece of plywood is appropriate, or a drum, both covered with plastic sheeting. Typically, a plastic table is provided for our use by our drilling crew. Note: Handle each sample liner with clean disposable gloves if environmental issues are being investigated. Measure and record the length of sample recovered making sure to discount any sloughed material that is present on top of the sample core. The sampler is then split into two (2) usually within the middle of the sampler and this will represent one (1) sample (i.e m to 0.76 m or S1 sample). Soil Description The criteria and procedures for identifying and describing soil include: i. Standard field identification method based on visual examination and manual tests; ii. A standard method of describing the soil by name and group symbol; iii. Verifying field description through inspection of representative soil samples by the person responsible for interpretation of subsurface conditions at the site; iv. Confirming descriptive information by laboratory determination of selected soil characteristics for representative soil samples; and v. Factual stratigraphic logs confirmed by the person responsible for interpreting the subsurface conditions. The stratigraphic log is a factual description of the soil at the borehole location and is relied upon to interpret the soil characteristics, and their influence and significance in the subsurface environment. The accuracy of the stratigraphic log is to be verified by the person responsible for interpreting subsurface conditions. An accurate description of the soil stratigraphy is essential for a reasonable understanding of the subsurface conditions. Confirmation of the field description by examination of representative soil samples by the project geologist, hydrogeologist, or geotechnical engineer (whenever practicable) is recommended. EDR-SOP-19 Page 3

181 The ability to describe and classify soil correctly is a skill that is learned from a person with experience and by systematic training and comparison of laboratory results to field descriptions. The description for natural undisturbed soil is recorded on the Borehole Log. The following information must be included on the borehole logs when collecting soil samples: A unique identification number of the borehole and or monitoring well (should one be installed); The date at which the soil samples were collected; A description of type and condition of geologic material encountered and or other material encountered. The use of the Unified Soil Classification System (USCS) group symbol(s) (e.g., SM) of primary soil components or dual and borderline symbols should be used; The soil color; The soil vapour measurement from field screening for volatile contaminants, including volatile organic compounds; The soil moisture content, using a qualitative description; The observations concerning the soil (i.e. staining, odours, discolouration, etc.); The identification of soil samples sent for laboratory analysis; The soil sample depths; The soil sampling methods; Evidence of free flowing product; The total depth drilled; They surveyed elevation of the well; and Any drilling refusal. Note: When describing observed odors, be specific in terms of general odor category and strength of odor noted. Odors may typically be chemical, petroleum or septic related. Avoid the use of subjective terms, such as slight, moderate, strong. Identification of specific chemical compounds (i.e., petroleum hydrocarbon) is acceptable; however, should be referenced as petroleum hydrocarbon-like staining or odour. Note: When describing vegetative matter presence in the soil column, do not use the term "organic" as this often leads to confusion with regard to organic chemical (i.e., PL or PHC) presence. The description of fill soil is similar to that of natural undisturbed soil except that it is identified as fill and not classified by USCS group, relative density, or consistency. EDR-SOP-19 Page 4

182 It is necessary to identify and group soil samples consistently to determine the subsurface pattern or changes and non-conformities in soil stratigraphy in the field at the time of drilling. The stratigraphy in each borehole during drilling is to be compared to the stratigraphy found at the previously completed boreholes to ensure that pattern or changes in soil stratigraphy are noted and that consistent terminology is used. Visual examination, physical observations, and manual tests (adapted from ASTM D2488, visual-manual procedures) are used to classify and group soil samples in the field and are summarized in this subsection. ASTM should be reviewed for detailed explanations of the procedures. Visual-manual procedures used for soil identification and classification include: Visual determination of grain size, soil gradation, and percentage fines; Dry strength, dilatancy, toughness, and plasticity (thread or ribbon test) tests for identification of inorganic fine grained soil (e.g., CL, CH, ML, or MH); and Soil compressive strength and consistency estimates based on thumb indent and pocket penetrometer methods. The three main soil divisions are: coarse-grained soil (e.g., sand and gravel), fine-grained soil (e.g., silt and clay), and soil with high natural organic matter content (e.g., peat and marl). A brief description of the criteria, procedures, and terminology used to identify and describe coarse and fine-grained soil is presented here. Coarse Grained Soil The USCS group symbols for coarse-grained soil are primarily based on grain or particle size, grain size distribution (gradation), and percent fines (silt and clay content). Coarse-grained soil is made up of more than 50 percent, by weight, sand size, or larger (75 μm diameter, No. 200 sieve size or larger). It is noted that there are other definitions for coarse grained or coarse textured soil and for sand size - such as soil having greater than 70 percent particles equal to or greater than 50 μm diameter (after "Guidelines for Contaminated Sites in Ontario") or 60 μm diameter ("Canadian Foundation Manual"). Descriptions for grain size distribution of soil include; poorly graded (i.e., soil having a uniform grain size, SP and GP) and well graded (i.e., poorly sorted; having wide range of particle sizes with substantial intermediate sizes, SW and GW). Coarse grained soils are further classified based on the percentage of silt and clay it contains (fines content). Coarse-grained soils containing greater than 12 percent fines are commonly described as dirty. This description arises from the soil particles that adhere when the soil is rubbed between the hands or adhere to the sides of the jar after shaking or rolling the soil in the jar. The jar shake test which results in segregation of the sand and gravel particles is also used as a visual aid in determining gravel and sand percentages. Examples of the group symbol, name, and adjectives used to describe the primary, secondary, and minor components of soil are; GW - Sandy Gravel (e.g., 70 percent gravel and 30 percent sand) or Sandy Gravel trace silt (less than 10 percent silt), and SF - Sand, uniform. EDR-SOP-19 Page 5

183 Relative density is an important parameter in establishing the engineering properties and behavior of coarsegrained soil. Relative density of non-cohesive (granular) soil is determined from standard penetration test (SPT) blow counts (N values) (after ASTM Method D1586). The SPT gives a reliable indication of relative density in sand and fine gravel. N values in coarse grained soil are influenced by a number of factors that can result in overestimates of relative density (e.g., in coarse gravel and dilatant silty fine sand) and can be conservative and underestimate the relative density (e.g., sand below the groundwater table and uniform coarse sand). These effects will be assessed by the project geotechnical specialist, if necessary, and need not be taken into account by field personnel. Other dynamic methods, such as modified SPT and cone penetration tests, are used on occasion to supplement or replace the SPT method for certain site-specific conditions. The details of all modifications to the SPT or substitute methods should be recorded as they are required to interpret test results and correlate to relative density. Fine Grained Soil A soil is fine grained if it is made up of half or more of clay and silt (i.e., fines greater than 50 percent by weight passing the 75 μm (No. 200) sieve size). A description of visual-manual field methods and criteria (after ASTM D2488) that are used to further characterize and group fine grained soil (e.g., CL, CH, ML, or MH) including dry strength, dilatancy, toughness, and plasticity (thread or ribbon test) follows: CRITERIA FOR DESCRIBING DRY STRENGTH Description Criteria None The dry specimen crumbles into powder with mere pressure of handling. Low Medium High Very High The dry specimen crumbles into powder with some finger pressure. The dry specimen breaks into pieces or crumbles with considerable finger pressure. The dry specimen crumbles into powder with finger pressure. Specimen will break into pieces between thumb and a hard surface. The dry specimen cannot be broken between the thumb and a hard surface. CRITERIA FOR DESCRIBING DILATANCY Description Criteria None No visible change in small wetted specimen when rapidly shaken in palm of hand. Slow Rapid Water appears slowly on the surface of the specimen during shaking and does not disappear or disappears slowly upon squeezing. Water appears quickly on the surface of the specimen during shaking and disappears quickly upon squeezing or stretching. EDR-SOP-19 Page 6

184 CRITERIA FOR DESCRIBING TOUGHNESS Description Criteria Low Only slight pressure is required to roll the thread near the plastic limit. The thread and the lump are weak and soft. Medium High Medium pressure is required to roll the thread to near the plastic limit. The thread and the lump have medium stiffness. Considerable pressure is required to roll the thread to near the plastic limit. The thread and the lump have very high stiffness. CRITERIA FOR DESCRIBING PLASTICITY Description Criteria Nonplastic A 1/8-inch (3 mm) thread cannot be rolled at any water content. Low Medium High The thread can barely be rolled and the lump cannot be formed when drier than the plastic limit. The thread is easy to roll and not much time is required to reach the plastic limit. The thread cannot be rerolled after reaching the plastic limit. The lump crumbles when drier than the plastic limit. It takes considerable time rolling and kneading to reach the plastic limit. The thread can be re-rolled several times after reaching the plastic limit. The lump can be formed without crumbling when drier than the plastic limit. Examples of group symbol identification based on visual-manual procedures and criteria for describing finegrained soil are: Group Symbol Dry Strength Dilatancy Toughness Plasticity ML None to low Slow to rapid Low or thread cannot be formed Slight CL Medium to high None to slow Medium Low MH Low to medium None to slow Low to medium Low CH High to very high None High High A requirement for positive classification by USCS group symbols (as described in ASTM D2487) is laboratory determination of particle size characteristics, liquid limit, and plasticity index. The need for this type of testing will be determined by the project geologist, hydrogeologist, or geotechnical engineer. A statement of qualification (method used) is required if group symbols are not determined by appropriate laboratory testing. EDR-SOP-19 Page 7

185 Examples of name terminology that accompanies the group symbols are ML - Sandy Silt (e.g., 30 percent sand) and CL- Lean Clay with sand (e.g., 15 to 29 percent sand). The USCS group symbols require the use of Lean Clay (CL) and Fat Clay (CH), depending on the plasticity of the soil. Classifications such as silty clay can only be used for a very narrow set of conditions, and should probably only be used if Atterberg Limit results are available. The Lean and Fat Clay designations are not universally used, but strict adherence to the USCS requires their use. The correlation between N value and consistency for clays is rather unreliable. It is preferable to determine consistency using more appropriate static test methods, particularly for very soft to stiff clay soil. N value estimates of consistency are more reasonable for hard clay. Chemical Description During soil examination and logging, the sampler shall carefully check for the presence of light or dense Non- Aqueous Phase Liquids (PL). PL may be present in gross amounts or present in small/minute quantities. The adjectives and corresponding quantities used when describing PL within a soil matrix are as follows: Visual Description Fraction of Soil Pore Volume Containing PL Saturated >0.5 Some Trace <0.25 A complete description of PL must describe the following: Color; Quantity; Density (compared to water, i.e., light/floats or heavy/sinks); Odor (if observed); and Viscosity (i.e., mobile/flowable, non-mobile/highly viscous-tar like). The presence of an "iridescent sheen" by itself does not constitute 'PL presence', but may be an indicator that PL is close to the area. PL presence within a soil matrix may be confirmed by placing a small soil sample within water, shaking, and observing for PL separation, i.e., light or dense, from the soil matrix. Trace amounts of PL are identified/confirmed by a close visual examination of the soil matrix, i.e., separate soil by hand (wearing disposable gloves) and perform a careful inspection of the soil separation planes / soil grains for PL presence. Often during the sample examination with a knife, an iridescent sheen will be noted on the soil surface (i.e., clay/silts) if the knife has passed through an area of PL. There are a number of more complicated tests available to confirm/identify PL presence. EDR-SOP-19 Page 8

186 Pinchin typically utilizes organic vapor detection results, visual examination, soil/water shake testing, and chemical analysis, to confirm PL presence. The more complex techniques may be incorporated on sites where clear colorless PL is present and its field identification is critical to the program. Representative portions of the soil sample must be retained for geologic record following description. Place the soil portions into labeled, sealable sample containers (usually mason jars) without destroying any apparent stratification. Chemical Sample Preparation and Packaging Subsurface soil samples are usually "grab samples", used to characterize the soil at a specific depth or depth interval (e.g., 2 to 4 feet). On occasion, composite samples are collected from a borehole over a greater depth interval (e.g., 5 to 15 feet). The following describes the collection of grab samples for chemical analysis (all soil from one split spoon). Clayey Soils Discard upper and lower ends of sample core (3 inches ±); Use a precleaned stainless steel knife; Cut the remaining core longitudinally; Remove soil (with a sample spoon) from the center portion of the core and place in a precleaned stainless steel bowl; Remove large stones and natural vegetative debris; and Homogenize the soil and place directly into the sample jars. Note: Samples for VOC analysis must not be homogenized. Collect soil from the length of the center portion of the core and place in the sample container. Completely fill the container. No air space (headspace) should remain. Sandy Soils As sandy soils have less cohesion than clayey soils, it is not easy to cut the core longitudinally to remove the center of the sample. Therefore, with a stainless steel spoon, scrape away surface soils, which have likely contacted the sampler and then sample the center portion of the soil core. Note: All soil samples collected for chemical analysis shall be placed immediately in a cooler with ice. All soil samples shall be recorded in the log book, and labeled appropriately. For analysis of low level VOCs (typically 1 to 200 μg/kg) soil is sealed in a specially prepared vial with a solution of sodium bisulfate. For higher levels of VOCs, the soil is placed in a vial with a volume of methanol. This method increases the complexity of collecting soils and makes it imperative that the sampler and contracted laboratory work closely together. Geotechnical/Hydrogeologic Sample Preparation and Packaging EDR-SOP-19 Page 9

187 When a sample is collected for geotechnical or hydrogeologic properties, the sample needs to be prepared and packaged in a manner to maintain its physical properties. Soil samples are usually grab samples, collected from a specific depth or depth interval (e.g., 2 to 4 feet). On occasion, composite samples are collected from the borehole over a greater depth interval (e.g., 5 to 15 feet). The following describes the collection of grab samples for geotechnical or hydrogeologic purposes for two common samplers, the split spoon and the thin wall samplers. Split Spoon Sample Following completion of PID screening, remove and dispose of soil at the top of the sample that is obviously sloughed material not representative of the soil at the sampled depth. Measure length of sample and record as the recovered length. If cohesive, perform pocket penetrometer reading and describe soil. Carefully transfer sample onto a sheet of aluminum or tin foil taking care to maintain structure and bedding of the soil sample as much as possible. This may not be possible with non-cohesive soils with low silt or clay contents. The sample may need to be packaged in three 6- to 8-inch segments. Roll the sample in the tin foil and fold over the ends to seal. Wrap in a second layer of tin foil. Identify the top, middle, and bottom segments with a T, M, and B using an indelible marker. For each segment, record the "up" direction with an arrow. Place the foil wrapped sample in a plastic bag and write the sample identification on the bag using an indelible marker. Storing the sample in foil, as opposed to a jar, has the advantage of retaining the soil's in-place structure and preventing loss of moisture. If the soils are sandy and it is not possible to retain the soils structure by rolling it in tin foil, packaging the sample in a jar is also acceptable, provided the jar is filled to eliminate air space that could result in the soil sample drying out. Thin Wall (Shelby Tube) Sample Remove any sloughed material from the top of the sample using a knife or similar long bladed instrument. If it is not possible to distinguish sloughed soil from intact soil, do not remove. Following removal of sloughed material, measure the tube length and the air space in the tube above the sample and record the difference as the sample recovery. In the unusual circumstance that there is also air space at the bottom of the sample, subtract this as well and record this latter measurement as a separate entry. Seal the top and bottom of the sample with wax (wax is normally provided and prepared by the driller) and first pour the liquefied wax into the top of the sample to a thickness of about 1 inch. Once this is cooled, remove approximately 1/2 inch of soil from bottom of sample (unless there is already a cavity at bottom of sample) and seal similarly. Fill the remaining air space above the sample with loose soil to prevent the sample from shifting in the tube, and then cap both ends of the sample with plastic caps. Tape the caps on using duct tape. Write the sample identification number on the cap using an indelible marker. Shelby tubes containing soft clays and wet silts need to be handled with care to avoid damage to the sample. Keep samples in an upright position at all times EDR-SOP-19 Page 10

188 and transport either in a specifically designed cushioned box or position in your vehicle with cushioning under and around the individual tubes. Communication of Field Findings Field findings should be communicated frequently with the office technical staff (usually the Project Manager) responsible for the program. This communication allows the office staff: to confirm that the investigation meets the intent of the Work Plan; to alter procedures and sampling protocol if soil conditions are markedly different from those assumed; and to assist in determining screening intervals for piezometers or monitoring wells. Call office staff no later than the completion of the first borehole, and sooner if possible. Be prepared to discuss the results by faxing the field logs beforehand (wherever possible) and by having a copy of the field log in hand when on the telephone. Call after each borehole and call before leaving the site. FOLLOW-UP ACTIVITIES The following shall be performed once field activities are complete. Double check Work Plan to ensure all samples have been collected and confirm this with the Project Manager, discuss sample selection as appropriate; Equipment shall be cleaned and returned to the equipment administrator and the appropriate forms dated and signed (i.e., equipment use, consumable field supplies); Complete water disposal (if required), and cleaning fluid disposal requirements per the Work Plan; Notify the contract laboratory as to when to expect the samples. The chain-of-custody and covering letter, indicating the parameters and number of samples, shall be enclosed in the sample cooler; After conducting a brief / de-brief session with the Project Manager, file all field notes and forms in the Pinchin project folder; and Return site/well keys (if applicable).

The C6-C10 fraction is calculated using toluene response factor. The C10 - C16, C16 - C34, and C34 - C50 fractions are calculated using the average response factor for n-c10, n-c16, and n-c34. Gravimetric Heavy Hydrocarbons are not included in the Total C16-C50 and are only determined if the chromatogram of the C34 - C50 hydrocarbons indicates that hydrocarbons >C50 are present. Total C6 - C50 results are corrected for BTEX and PAH contributions. This method complies with the Reference Method for the CWS PHC and is validated for use in the laboratory. nc6 and nc10 response factors are within 30% of Toluene response factor. nc10, nc16 and nc34 response factors are within 10% of their average. C50 response factor is within 70% of nc10 + nc16 + nc34 average. Linearity is within 15%. Extraction and holding times were met for this sample.

The C6-C10 fraction is calculated using toluene response factor. The C10 - C16, C16 - C34, and C34 - C50 fractions are calculated using the average response factor for n-c10, n-c16, and n-c34. Gravimetric Heavy Hydrocarbons are not included in the Total C16-C50 and are only determined if the chromatogram of the C34 - C50 hydrocarbons indicates that hydrocarbons >C50 are present. Total C6 - C50 results are corrected for BTEX and PAH contributions. This method complies with the Reference Method for the CWS PHC and is validated for use in the laboratory. nc6 and nc10 response factors are within 30% of Toluene response factor. nc10, nc16 and nc34 response factors are within 10% of their average. C50 response factor is within 70% of nc10 + nc16 + nc34 average. Linearity is within 15%. Extraction and holding times were met for this sample.

Gravimetric Heavy Hydrocarbons are not included in the Total C16-C50 and are only determined if the chromatogram of the C34 - C50 hydrocarbons indicates that hydrocarbons >C50 are present. Total C6 - C50 results are corrected for BTEX and PAH contributions. This method complies with the Reference Method for the CWS PHC and is validated for use in the laboratory. nc6 and nc10 response factors are within 30% of Toluene response factor. nc10, nc16 and nc34 response factors are within 10% of their average. C50 response factor is within 70% of nc10 + nc16 + nc34 average. Linearity is within 15%. Extraction and holding times were met for this sample.

The C10 - C16, C16 - C34, and C34 - C50 fractions are calculated using the average response factor for n-c10, n-c16, and nc34. Gravimetric Heavy Hydrocarbons are not included in the Total C16 - C50 and are only determined if the chromatogram of the C34 - C50 Hydrocarbons indicated that hydrocarbons >C50 are present. Total C6-C50 results are corrected for BTEX and PAH contributions. This method complies with the Reference Method for the CWS PHC and is validated for use in the laboratory. nc6 and nc10 response factors are within 30% of Toluene response factor. nc10, nc16 and nc34 response factors are within 10% of their average. C50 response factor is within 70% of nc10 + nc16 nc34 average. Linearity is within 15%. Extraction and holding times were met for this sample.

The C10 - C16, C16 - C34, and C34 - C50 fractions are calculated using the average response factor for n-c10, n-c16, and nc34. Gravimetric Heavy Hydrocarbons are not included in the Total C16 - C50 and are only determined if the chromatogram of the C34 - C50 Hydrocarbons indicated that hydrocarbons >C50 are present. Total C6-C50 results are corrected for BTEX and PAH contributions. This method complies with the Reference Method for the CWS PHC and is validated for use in the laboratory. nc6 and nc10 response factors are within 30% of Toluene response factor. nc10, nc16 and nc34 response factors are within 10% of their average. C50 response factor is within 70% of nc10 + nc16 nc34 average. Linearity is within 15%. Extraction and holding times were met for this sample.

The C6-C10 fraction is calculated using toluene response factor. The C10 - C16, C16 - C34, and C34 - C50 fractions are calculated using the average response factor for n-c10, n-c16, and n-c34. Gravimetric Heavy Hydrocarbons are not included in the Total C16-C50 and are only determined if the chromatogram of the C34 - C50 hydrocarbons indicates that hydrocarbons >C50 are present. Total C6 - C50 results are corrected for BTEX and PAH contributions. This method complies with the Reference Method for the CWS PHC and is validated for use in the laboratory. nc6 and nc10 response factors are within 30% of Toluene response factor. nc10, nc16 and nc34 response factors are within 10% of their average.

The C6-C10 fraction is calculated using toluene response factor. The C10 - C16, C16 - C34, and C34 - C50 fractions are calculated using the average response factor for n-c10, n-c16, and n-c34. Gravimetric Heavy Hydrocarbons are not included in the Total C16-C50 and are only determined if the chromatogram of the C34 - C50 hydrocarbons indicates that hydrocarbons >C50 are present. Total C6 - C50 results are corrected for BTEX and PAH contributions. This method complies with the Reference Method for the CWS PHC and is validated for use in the laboratory. nc6 and nc10 response factors are within 30% of Toluene response factor. nc10, nc16 and nc34 response factors are within 10% of their average. C50 response factor is within 70% of nc10 + nc16 + nc34 average. Linearity is within 15%. Extraction and holding times were met for this sample.
