4 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April INTRODUCTION WESA, a division of BluMetric Environmental Inc. was retained by Westboro Mortgage Investment Corp. to conduct a terrain analysis and hydrogeological investigation for the proposed Riverbend Mixed Use Subdivision. The subject property is located on Part of Lots 7 and 8, Concession IV, former Township of Goulbourn, now the City of Ottawa, Ontario (Figure 1). Lands for the proposed development are bounded by Copeland Road and Franktown Road to the north and south, respectively, and by the existing Riverbend Golf Course and the Heron Lake Estates subdivision to the east and west respectively (Figure 2). The lands are bisected by the Jock River and consist primarily of former agricultural and/or pasture lands and lands formerly developed as part of the former Poplar Grove Golf Club (Paterson, 2009a). The total area of the proposed development is approximately 22 hectares (Ha). Currently, the areas proposed for development are zoned Open Space (O1A) and Rural Countryside (RU), which is to be amended as required as part of the approval process. The proposed development involves the subdivision of the property into 16 residential lots, ranging in size from 0.8 Ha to 1.2 Ha, and 5 commercial lots, ranging in size from 0.9 Ha to 1.5 Ha (Figure 2). It is proposed that the lots be privately serviced with individual water supply wells and Class 4 septic systems. 1.1 OBJECTIVE This report summarizes the results of a detailed investigation of the geology, physiography, and hydrogeology of the property proposed for subdivision. The results address the following concerns as outlined in the Ontario Ministry of the Environment and Climate Change s (MOECC) (formerly referred to as the Ministry of Energy and Environment (MOEE) and Ministry of Environment (MOE)) technical guideline, MOE Hydrogeological Technical Information Requirements for Land Development Applications, April 1995 and addendums : The suitability of soils for the installation of Class 4 septic systems and their capability to attenuate sewage effluent and prevent subsurface contamination. The ability of groundwater to provide adequate quantities of potable water. The development of a well-planned subdivision in light of any site development constraints present. The optimum design of private services. An Environmental Impact Assessment for the private sewage systems in accordance with MOECC technical guidelines. Page 1 WESA

5 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April METHODOLOGY The study was completed using a combination of background research and on site investigations. The MOECC documents Procedure D-5-4 Technical Guideline for Individual On-Site Sewage Systems: Water Quality Impact Risk Assessment last revised August 1995, Procedure D-5-5 Technical Guideline for Private Wells: Water Supply Assessment, last revised August 1996 as well as the Manual of Policy, Procedures and Guidelines for Onsite Sewage Systems dated May 1982 were used as the primary guidelines for assessment of the proposed development Background Data Review and Pre-Consultation Meeting The initial task completed involved the assembly and review of all available pertinent literature and maps, including previous studies on or in the vicinity of the property, which are used as supplemental data sources within the current investigation. The list of available reports is as follows: Phase I Environmental Site Assessment 8089 Franktown Road Part of Lots 7 & 8, Concession 4, Ottawa (Goulbourn), Ontario. Paterson Group Inc. December 4, (Paterson, 2009a) Terrain Analysis and Hydrogeological Study Proposed Residential Subdivision, Part of Lots 7 & 8, Concession 4, Ottawa (Goulbourn), Ontario. Paterson Group Inc. December 3, (Paterson, 2009b) Available MOECC water wells records, from the Water Well Information System (WWIS) were compiled for an area extending up to 1 km beyond the proposed licensed boundary (Figure 4). A total of 89 records were identified for this area and geographically referenced based on available information. The well record information was assessed to interpret local geology, hydrogeology, and to identify the water supply aquifers/sources currently being utilized. Several of these well records were eliminated from consideration based on information inferred to be inaccurate regarding reported well locations and well properties. Additional relevant geological and hydrogeological background information was obtained from relevant published sources. On October 20, 2014 a pre-consultation meeting was conducted with representatives of the Rideau Valley Conservation Authority (RVCA), City of Ottawa Policy Development and Urban Design Branch, Westboro Mortgage Investment Corp., Novatech Engineering Ltd. and BluMetric Environmental Ltd. The objective of the meeting was to review the proposed development plan and to ensure the hydrogeological assessment addressed all requirements and potential concerns of the municipality and its technical reviewers. It was noted in this meeting that a previous terrain and hydrogeological assessment of the property was completed and Page 2 WESA

6 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 submitted to the City of Ottawa (Paterson 2009b). It was agreed at this meeting that a standalone report would be prepared and that any supplemental data/information derived from the Paterson, 2009b report would be provided under one report cover. Specific items requested by RVCA to be included in the assessment included metals and herbicides/pesticides analysis for groundwater, nitrate loading assessment for proposed commercial use lots, and potential for water quality impact to the Jock River Drilling Program As part of the previous Terrain Analysis and Hydrogeological Study in 2009 (Paterson, 2009b), various test holes and test pits were completed across the property using a hand auger and backhoe, respectively, to assess site terrain conditions. The depth of overburden investigation ranged between 0.53 and 2.00 metres below ground surface (m bgs) and bedrock was not encountered at 2.00 metres at some site locations. Foour test wells (TW1 to TW4) were drilled on-site under Paterson s supervision to characterize the physical and chemical hydrogeology of the bedrock aquifer. The MOECC water well records for the four test wells constructed in 2009 are included within Appendix A. The test wells were constructed between September 24 and October 6, 2009 by an MOECC licensed well contractor (Air Rock Drilling Company Ltd. of Ottawa, Ontario). The associated test well locations are included on Figure 2, along with the Paterson, 2009b test hole locations TH1 to TH11 and test pit locations TH12 to TH15. The associated soil stratigraphic logs and grain size analyses are included in Appendix A. Excavation depths and observed water table depths for TH1 to TH15 are shown on Figure 3. Based on a review of the Paterson, 2009b findings, a supplemental drilling program was completed by WESA to further assess site terrain conditions and depth to bedrock across the property. The drilling program included the advancement of eight boreholes across the site to bedrock refusal. Three of the boreholes, each located in close proximity to an existing bedrock test well, were instrumented as overburden monitoring wells to assess static water table and vertical hydraulic gradient conditions. Prior to commencement of the drilling program, all investigation areas were cleared for subsurface utilities by Ottawa Valley Locate (OVL) of Ottawa, Ontario. A copy of the clearances is attached within Appendix B. WESA was on-site on November 22 and 23, 2014 to supervise the drilling activities, which were conducted by Aardvark Drilling Ltd. of Carleton Place, Ontario using a track mounted CME 75 drilling rig with hollow stem auger drilling equipment. Soil samples were collected using a 0.6 m long by 0.05 m diameter split-spoon sampler. The eight borehole locations, TH16 to TH23 are identified on Figure 2. The observed soil profiles at each borehole location are depicted on Figure 3. Each borehole was advanced to auger refusal (inferred as bedrock refusal) and completed to final depths ranging between 0.94 and 3.35 m bgs. The annular space of each borehole was backfilled with a combination of bentonite chips and native material, with the Page 3 WESA

7 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 exception of boreholes TH16, TH19 and TH23, which were completed as overburden monitoring wells identified as TW5, TW6 and TW7, respectively. Each monitoring well was constructed using 50 mm inside diameter (ID) PVC well risers and 50 mm ID 10-slot PVC well screens. A No. 3 silica sand pack was placed around the outside of the well screens in the annular space of the borehole. A bentonite clay seal was subsequently placed above the sand pack. The borehole logs summarizing soil profiles and overburden test well construction can be found within Appendix C. Overburden units on the property were identified based on the soil type and stratigraphy observed at each borehole completed under the supervision of WESA and using supplemental soil log data available in Paterson 2009b (soil logs provided in Appendix A). Terrain units for the top 1.5 m of overburden were mapped for the study area based on the distribution of the overburden units, the depth to bedrock and the water table, and consideration of physiographic features such as surface water bodies and bedrock outcrops present on the subject property. The hydraulic properties of the soils within the mapped terrain units were inferred from their geological characteristics (i.e. lithology, grain-size, sorting, etc.). The capacity of terrain units to effectively attenuate septic sewage effluent was assessed based on their geological and hydrogeological characteristics Baseline Static Water Level Elevations Baseline static groundwater elevations were collected on October 16, 2014 for the bedrock aquifer from each of the pre-existing on-site test wells (TW1 to TW4). Static groundwater elevations were also collected from each of the newly installed overburden monitoring wells (TW5 to TW7) on November 23, Due to the flowing artesian conditions observed at TW1 and TW4, the casing at these locations were temporarily extended using 5/8 outside diameter (OD) low density polyethylene (LDPE) tubing fitted to a sanitary well cap. The baseline water levels are summarized in Table 3 and discussed in Section of this report Aquifer Testing and Groundwater Sampling Program Aquifer Testing Program The viability of the local bedrock aquifer(s) as a water supply for the proposed subdivision development was evaluated through the completion of an aquifer testing program in conjunction with a groundwater sampling program at each of the four existing bedrock test well locations (TW1 to TW4). The design and methodology of the pumping tests followed the requirements described within Section 4.3 of MOECC Procedure D-5-5. Page 4 WESA

8 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 Constant discharge pumping tests were conducted by WESA on each of the four test wells between October 16 and 17, 2014 using 1/2 HP electric submersible pumps powered by portable gasoline generator. The 1 OD black polyethylene (PE) discharge tubing was extended at least 30 m in the downslope direction of each pumping well to minimize the potential for any artificial recharge of the aquifer. The submersible pump intake was set 1.5 metres above the bottom of each test well to provide a maximum amount of available drawdown. Prior to pumping, static water levels were collected at the pumping wells as well as observation wells where possible. Where flowing artesian conditions were encountered, static water levels were recorded prior to pump installation, which were assumed to represent initial water levels at time(t)=0. Each well was pumped at a constant discharge rate of 30.3 L/min (8 US gallons per minute) for a period of 6 hours. Water levels were recorded manually within each pumping well and within select observation wells. After 6 hours of pumping, the wells were allowed to recover and water levels were recorded over a period of 2 hours or until a minimum of 90% recovery was obtained. The aquifer testing data were analyzed using AquiferTest (2011.1) aquifer analysis software in conjunction with the Theis pumping, Agarwal, and Theis recovery analytical methods. Analytical methods were chosen given the following assumptions: Each test well draws water within the competent bedrock and the aquifer is isolated from near-surface hydraulic influences. Each test well is characterized by near surface static water levels or flowing artesian conditions, suggesting confined aquifer conditions. Due to insufficient drawdown observed within the observations wells for analyses, single well analyses were required. The potential for well bore storage and skin effects should be considered due to the nature of single well analyses. The raw water level data, as well as the associated graphs and analyses produced using the AquiferTest software for each pumping test are included within Appendix E, where applicable, along with the calculated values for transmissivity (T). Results are compared to aquifer test results presented in Paterson 2009b to assess for any possible change to aquifer conditions or well hydraulics. Groundwater Sampling Program A groundwater sampling program was conducted in conjunction with the aquifer testing program at each of the four test wells. All wells were shock chlorinated one week prior to testing, though maintenance of a high chlorine residual within test well TW1 was not possible due to the strong artesian flow conditions. Groundwater samples were collected on October 16 and 17, 2014 from the pump test discharge line after 3 and 6 hours of pumping, with the final sample collected just prior to the pump being shut off. Samples were analysed for the list of chemical and Page 5 WESA

April 2015 bacteriological parameters specified within MOECC Procedure D-5-5, and for additional selected metals parameters as specified by RVCA. Field measurements for temperature, ph, and conductivity were collected throughout the pumping tests using a YSI 556 MPS multi-parameter instrument calibrated at the beginning of each day. In addition, free chlorine residual measurements were collected in the field using a Hach Colorimeter II Chlorine instrument and field turbidity measurements were collected using a Hach 2100P Turbidimeter. In addition to the sampling program described above, and as requested by RVCA, a groundwater sample was collected on November 7, 2014 from bedrock test well TW1, which is located adjacent to the Riverbend Golf Course, for mercury, orthophosphate, pesticides and herbicides analysis. Furthermore, nitrate species parameter sampling was attempted for overburden monitoring wells TW5 and TW7 on December 9, Collection of groundwater from TW5 was obstructed due to the presence of ice, while TW7 was successfully sampled. An existing residential subdivision, referred to as Heron Lake Estates is located adjacent to the western boundary of the proposed Riverbend mixed use subdivision. Heron Lake Estates was approved for development in the mid 1980 s and no terrain and hydrogeological assessment reports for this development could be located within City of Ottawa files. Water supply well sampling was conducted within the Heron Lake Estates development by WESA using information from available MOECC water well records as its basis. Two existing water supply wells located within Heron Lake Estates were identified with matching MOECC water well records indicating similar hydrogeological conditions to be encountered for water supply wells constructed within the proposed Riverbend development. The intent of the sampling program was communicated to the Community Association by telephone and to the selected residences by mail correspondence. Groundwater quality sampling was completed for the two wells, (1 Lakewood Drive and 9 Lakewood Drive), for comparison to the test well sampling results and to assess for any indications of water quality degradation resulting from residential development on private servicing within the Heron Lake Estates property. All collected groundwater samples were submitted to Maxxam Analytics Inc. of Ottawa, Ontario (Maxxam) under strict chain of custody (COC) procedures. Maxxam is accredited for the applicable analyses under the Canadian Association for Laboratory Accreditation Inc. (CALA) and the Standards Council of Canada (SCC), which are equivalent accreditations. Samples were stored at a temperature less than 4 o C in a cooler during shipment to the laboratory for chemical analyses. The relevant laboratory certificates of analysis are included as Appendix F. Results from the water quality analyses are summarized within Tables 1 and 2 in comparison with the current Ontario Drinking Water Standards, Objectives and Guidelines (MOECC, 2006) and the criteria prescribed within MOECC Procedure D-5-5.

10 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April PHYSICAL SETTING 2.1 SITE PHYSIOGRAPHY AND DRAINAGE The subject property is located within the Smiths Falls Limestone Plains physiographic region, with localized physiographic landforms such as beaches on-site, as well as sand plains and peat and muck landforms in the surrounding properties (Chapman & Putnam, 2007). Based on the available topographic maps and observations noted during various site visits, the site topography is generally flat to undulating and gently slopes towards the Jock River. The maximum relief across the subject property is estimated to be less than 2 metres. Site drainage is controlled by local topography, with precipitation inferred to be primarily infiltrating into the shallow overburden along with some localized overland flow towards the Jock River, which flows from northwest to southeast across the site. No notable low lying areas or standing water conditions were observed during various site visits conducted between October and December, SITE GEOLOGY This section describes the surficial and bedrock geology of the study area. Information was obtained from published federal and provincial geologic maps and reports. Additional information is provided based on the results of the WESA on-site drilling program and the Paterson, 2009b data included in Appendix A. 2.3 SURFICIAL GEOLOGY Based on the available geologic maps, the surficial geology of the site is primarily composed of sandy silt to silty sand textured till material, with some occurrences of organic deposits, modern alluvial deposits and coarse textured glaciomarine deposits. Bedrock outcrops are also present beyond the subject property boundaries. The on-site surficial geology is generally consistent with that of the surrounding lands, including the properties associated with the Heron Lake Estates Subdivision (OGS, 2010) Based on the investigation results summarized on Figure 3, the overburden thickness over bedrock across the site ranges between 0.6 m in the southern portion of the site to 3.4 m in the northern portion, with some variations throughout the property. The potential occurrence of bedrock outcrop identified within the available surficial geology maps (OGS, 2010) for the southern portion of the site was investigated on site and no bedrock outcrops were observed. Based on investigation data, the bedrock depth in this site area ranges from 0.6 m to 1.5 m. Page 7 WESA

11 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 Where present, the overburden material in the southern portion of the site was observed to be relatively homogenous in vertical and horizontal extent and generally consisted of topsoil overlaying fine sand/silt with some/trace gravel. Paterson, 2009b collected a soil sample for grain size analysis from what is interpreted by WESA to be the overburden material described above. The results of the grain size analysis, provided in Appendix A, indicates a grain size distribution of 77% sand, 21% silt/clay and 2% gravel, which is consistent with field observations made during the WESA site assessment. In the northern portion of the subject property and north of the Jock River, the overburden material was observed to generally consist of topsoil overlaying sandy/silty clays and/or clayey sands/silts. A grain size analysis is proved in Paterson 2009b, from what is interpreted by WESA to be the overburden material described by WESA as sandy/silty clays and/or clayey sands/silts. The results of the grain size analysis, provided ins Appendix A, indicates a grain size distribution of 61% sand, 35% silt/clay and 4% gravel, which is consistent with field observations made during the WESA site assessment. Gravel and angular bedrock fragments were generally observed near the bedrock surface throughout the site where bedrock was encountered. Borehole logs associated with test holes advanced in 2014 under WESA s supervision can be found within Appendix C Bedrock Geology The subject property and surrounding lands are underlain by limestone of the Oxford Formation of the Paleozoic Period (GSC, 1979). MOECC water well records for the four bedrock test wells (TW1 to TW4) report the presence of limestone to a depth of at least 30 m bgs. Published mapping suggests a small portion of the subject property in the northeastern corner, as well as adjacent land to the northeast of the site may be underlain by shale of the Rockcliffe Formation, also of the Paleozoic Period (GSC, 1979). Shale is reported in well record , located 500 m north of the proposed development. 2.4 TERRAIN UNITS Two major overburden stratigraphic units were identified and characterized based on the observations, sampling results and interpretations associated with the on-site drilling and excavation programs conducted by Paterson in 2009 and by WESA in 2014, as described in Section above. For the purposes of terrain unit mapping as screening criteria for septic system design, the overburden material composition and presence of bedrock up to 1.5 m from ground surface was used to identify and map terrain units. Page 8 WESA

12 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 The estimated areal extent of the various identified terrain units are mapped within Figure 5 based on the available information. It should be noted that variations in subsurface investigation methodology (hand auger vs back hoe vs drill rig) and/or localized variations in bedrock surface topography are considered to be likely and could limit the accuracy of interpolations between data points. A generalized safety factor for unit thickness of -/+ 0.5 m has been used to reduce the probability of under/over estimating the terrain unit thickness available at each of the associated lot properties. General approximations of hydrogeological properties were inferred based on the results of the grain size analyses as well as other physiographic features described in Section 2.1 above. Based on the available information and interpretations, a terrain unit map delineating the spatial distribution of the terrain units was generated as Figure 5. Lot classification based on terrain units provides a basis for assessing lot specific conditions affecting Class 4 septic system design. Topsoil was encountered at ground surface at every test hole or test pit completed by both Paterson and WESA, and was typically observed to be between 0.05 and 0.3 m thick. Each underlying terrain unit is described below: Shallow Fine Sand/Silt over Bedrock (SM/BR) The shallow sand/silt over bedrock (SM/BR) terrain unit is composed primarily of the overburden unit described in Section as fine sand/silt with some/trace gravel. The results associated with the grain size sample collected by Paterson in 2009 and interpreted by WESA to be representative of the SM/BR terrain unit, the material is composed of 77% sand, 21% silt/clay and 2% gravel, which is generally consistent with field observations made by WESA (Paterson, 2009b). According to the Unified Soil Classification System, the sample would be classified as silty sand (group symbol: SM). In addition to material composition, this terrain unit was identified and delineated based on its thickness overlaying the bedrock surface. Based on the available bedrock surface depth data summarized in Figure 3, the overall thickness of this terrain unit is notably less than 1.5 metres, generally between 0.6 and 1.3 m. Typical percolation time (T) ranges for various soil types are listed in the Manual of Policy, Procedures and Guidelines for On-Site Sewage Systems (MOECC, 1982). Based on the overall physical properties (grain size, compaction, density) of the material encountered within the fine sand/silt terrain unit described above, the associated percolation time (T) can be estimated to range between 8 to 20 min/cm, with medium to low permeability (MOECC, 1982). Page 9 WESA

13 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 Clayey Silty Sand Unit (SC) The clayey silty sand (SC) terrain unit is composed primarily of the overburden unit described in Section as fine sandy/silty clays and/or clayey fine sands/silts. The results associated with the grain size sample collected by Paterson in 2009 and interpreted by WESA to be representative of the SM/BR terrain unit, the material is composed of 61% sand, 35% silt/clay and 4% gravel, which is generally consistent with field observations made by WESA (Paterson, 2009b). According to the Unified Soil Classification System, the sample would be classified as clayey silty sand (group symbol: SC). In addition to material composition, this terrain unit was identified and delineated based on its thickness overlaying the bedrock surface. Based on the available bedrock surface depth data summarized in Figure 3, the overall thickness of this terrain unit is greater than 1.5 metres, generally between and 1.3 m. Based on the overall physical properties (grain size, compaction, density) of the material encountered within the clayey silty sand terrain unit described above, the associated T-times can be estimated to range between 30 to 50 min/cm, with medium to low permeability (MOECC, 1982). Clayey Silty Sand Over Bedrock Unit (SC/BR) Similarly to the SC terrain unit, the sandy/silty clay over bedrock (SC/BR) terrain unit is composed primarily of the overburden unit described in Section as fine sandy/silty clays and/or clayey fine sands/silts. The associated grain size distribution and hydrogeological properties are interpreted to be comparable to the SC terrain unit described above. The SC/BR unit is distinguished from the SC unit based on the overall overburden unit thickness, which is generally less than 1.5 m and between 0.6 and 1.2 m based on the available bedrock surface depth data summarized in Figure 3. Based on the overall physical properties (grain size, compaction, density) of the material encountered within the clayey silty sand over bedrock (SC/BR) terrain unit described above, the associated T-times can be estimated to range between 30 to 50 min/cm, with medium to low permeability and is comparable to the PT value estimated for the (MOECC, 1982).

14 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April HYDROGEOLOGY Regional Hydrogeology The proposed development is located within the Jock River sub-watershed. Regional groundwater flow is inferred to be from the northwest to southeast towards the Rideau River based on the regional topography and watershed catchment area. Based on the available physiographic, surficial geology and information obtained from the MOECC well records (summarized in Appendix A), there is no evidence to suggest that there exists a notable groundwater aquifer within the overburden in the surrounding area of the site. The majority of identified water supply wells are completed to depths ranging between 11 and 30 m bgs, with some wells completed to depths up to 61 m bgs. Major water bearing zones were reportedly encountered between 10 and 45 m bgs. Very shallow or flowing static water levels were also generally reported, which suggest the presence of confining aquifer conditions and strong upward vertical gradients within the bedrock unit. As part of an ambient groundwater geochemistry study in southern Ontario completed by the Ontario Geological Survey (OGS, 2014), two bedrock test wells were constructed within a 5 km radius of the proposed subdivision development. These wells identified as 12-AG-070 and 12-AG-073 are located approximately 4.2 km from the Site to the southwest and northeast, respectively. Test well 12-AG-070 was drilled to a depth of m bgs and identified an overburden thickness of 0.61 m, while test well 12-AG-073 was drilled to a depth of m bgs and identified an overburden thickness of 1.22 m. The results from groundwater samples collected from these test wells in June, 2012 as part of the ambient groundwater geochemistry study are reproduced herein as Appendix D along with the applicable Ontario Drinking Water Standards. These results suggest that the presence of acceptable water quality within the bedrock aquifer unit in the area surrounding the proposed subdivision Site Hydrogeology Based on site topography, the inferred groundwater flow direction within the shallow overburden on site is towards the Jock River following local ground surface and bedrock surface topography. The local bedrock groundwater flow direction is inferred to follow regional groundwater flow direction from northwest to southeast towards the Rideau River as described in Section The local site hydrogeology was characterized using information obtained from the pre-existing bedrock test wells TW1 to TW4 installed under supervision of Paterson (Paterson, 2009b) in conjunction with the results associated with the additional drilling activities completed by WESA Page 11 WESA

April 2015 in 2014, which included the installation of overburden monitoring wells TW5 to TW7. The locations of all investigation wells can be found within Figure 2. A summary of test well construction details along with baseline static water level data collected by WESA in October and November, 2014 can be found within Table 1 below.

F Indicates the presence of flowing artesian conditions TOC Top of Casing TPVC Top of PVC standpipe A water table within the overburden unit was observed during the completion of subsurface investigation activities and at the three overburden monitoring well locations. Observations suggest that the overburden water table depth is variable throughout the site. Where present, the water table depth was observed to range between 0.2 m (TW5 on Nov 23, 2014) to 1.1 m below ground surface in the southern portion of the site characterized by a shallow bedrock surface (<1.5 m bgs) and between 0.6 to 1.8 m below ground surface in the northern portion of the site in areas characterized by a deeper bedrock surface (>1.5 m bgs). Test holes completed along the eastern subdivision boundary south of the Jock River generally did not report any notable evidence of water in the overburden, with the exception of TH9. The available information suggests that the water table within the overburden is likely perched on the bedrock surface, which is interpreted to represent an impermeable lower boundary. This shallow perched water table is interpreted to be primarily recharged by precipitation infiltrating into the subsurface. There is no evidence to suggest that there exists a notable or sensitive aquifer within the shallow overburden unit. Observations were completed during the fall season when water table conditions are typically at a high though potentially higher water table conditions may occur in the spring due to the freshet. Comparison of water levels observed for the bedrock test wells and the overburden monitoring wells indicates a strong upward vertical gradient for groundwater flow between overburden and bedrock. The higher static pressure within the bedrock aquifer compared to the overburden water table at the site is considered protective of any downward migration of potential impacts derived near surface.

16 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 Based on information in the MOECC water well records (Appendix A), Test well TW1 (Block 21) was completed to a depth of 24.4 m bgs, with reported major water bearing zones intersected at depths of 20.7 m bgs and 22.9 m bgs. Test well TW2 (Block 18) was completed to a depth of 30.5 m bgs, with reported major water bearing zones intersected at depths of 17.1 m bgs and 28.3 m bgs. Test well TW3 (Lot 4) was completed to a depth of 18.3 m bgs, with one reported major water bearing zone intersected at a depth of 14.9 m bgs. Test well TW2 (Block 18) was completed to a depth of 27.4 m bgs, with reported major water bearing zones intersected at depths of 17.1 m bgs, 23.5 m bgs and 25.9 m bgs. Air Rock Drilling reported flowing artesian conditions at all test wells with the exception of TW2, which exhibited non-flowing artesian conditions (static water level above ground surface but below top of casing). This suggests that strong confining aquifer conditions are present within the bedrock aquifer throughout the site, with strong upward vertical hydraulic gradients. The on-site hydrogeological conditions described above are generally consistent with the data collected as part of Aquifer Testing To evaluate whether the on-site bedrock aquifer was suitable for the development of private well water supplies, aquifer testing was conducted by WESA on the four bedrock test wells (TW1 to TW4), constructed across the site in Based on the available data, the construction of these wells is typical of water supply wells found within the adjacent Heron Lake Estates subdivision and representative of those wells recommended for construction in the proposed development. The water level data and observations associated with the pumping tests can be found within Appendix E. The analyses of the data collected during testing can be found within Appendix E and are summarized within Table 2 below. Page 13 WESA

Flowing artesian conditions were observed prior to the start of pumping and were observed throughout the duration of the test. As a result, the collected data could not be analyzed to determine aquifer properties. The aquifer test results indicate that test wells TW1, TW2, TW3 and TW4 produced well over the minimum required volume of water for a 4-bedroom residence (18.75 L/min, 6,750 L/day) with sustained pumping rates well above peak water demand rates as per Procedure D-5-5. No drawdown was recorded at test well TW1, while TW2 and TW4 exhibited 90% recovery within 2 minutes of pump shut off. Test well TW3 recovered to 90% within 80 minutes. Consequently, all test wells demonstrated recovery rates well within acceptable parameters without evidence of aquifer mining. All observation wells monitored showed no appreciable change in static water levels in response to pumping of other site wells. The average transmissivity values obtained for the test wells ranged between 0.64 and 2.3 m 2 /d, indicating highly transmissive aquifer conditions with potential yield in excess of requirements for the proposed development. Based on the results of the aquifer testing program the long-term sustainability of the site bedrock aquifer is considered acceptable for the proposed residential development. Further, the testing that was completed at a minimum 30.3 L/min (i.e. over 10,000 L pumped in 6 hours) indicates more than adequate yield for most small-scale commercial development uses. In the event that large scale water takings (>50,000 L pumped in one day) are deemed necessary, a more detailed assessment would be required from the proponent during the MOECC Permit To Take Water Page 14 WESA

18 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 (PTTW) application process. Details on recommended well design and construction for future water supply wells throughout the proposed subdivision are included within Section 3.2 below. 2.6 WATER QUALITY Overburden Unit Based on the available information, there is no potential for the construction of suitable water supply wells within the on-site overburden unit. Therefore, no samples were collected for drinking water parameter analysis. However, a sample was collected from overburden test well TW7 on December 9, 2014 for nitrate species parameters. TW7 is located on Block 21, a proposed commercial lot located immediately adjacent to the existing golf course and the previous location of additional holes/fairways from the golf course. The analytical results suggested that nitrate and nitrite parameter concentrations were below the laboratory detection limits, while ammonia and TKN were measured at relatively low concentrations. Based on the low ammonia concentration, the TKN concentration is inferred to be predominantly composed of organic nitrogen, whose source is inferred to be typically naturally occurring in the form of plant residue and compost (Freeze and Cherry, 1979). Furthermore, there is no evidence to suggest that groundwater within the on-site shallow overburden unit has been adversely impacted from the activities associated with the adjacent golf course or previous property use as a golf course. Bedrock Aquifer Groundwater samples were collected by WESA at test wells TW1 to TW4 in conjunction with the aquifer testing program on October 16 and 17, 2014 to characterize local and site bedrock groundwater quality conditions. Additional samples were collected from two water supply wells located within the adjacent Heron Lake Estates subdivision on December 9, Samples were submitted for laboratory analysis as described in Section All well water quality sampling results are provided in Table 3 (General Chemistry and Metals) and Table 4 (Pesticides and Herbicides) and are compared against the standards and objectives for applicable parameters listed in Procedure D-5-5, the Ontario Drinking Water Standards (ODWS, June 2003, revised 2006), and the maximum reasonably treatable concentrations (as outlined in Procedure D-5-5) for each water quality parameter analysed, where available. Laboratory certificates of analyses for sampling completed in 2014 are provided in Appendix F. Well water quality sampling data from Paterson, 2009b is included in Table 3 for assessment of any potential change in well water quality over the past five years. Page 15 WESA

19 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 A review of the analytical data summarized in Tables 3 indicate similar water quality between the 2009 and 2014 well water sampling event dates. Most parameters analysed in 2014 were found at levels below the acceptable Procedure D-5-5 objective and the ODWS standard during both rounds (3-hour and 6-hour marks during pump testing) of groundwater sampling. Most tested parameters showed a slight decrease in concentration levels (i.e. an improvement in water quality) from the initial sampling at 3-hours of pumping to the subsequent sampling after 6-hours of pumping. This observation is attributed to the wells not having been actively pumped in nearly five years and an additional extended period of pumping may result in further improvement in well water quality. In some cases, the 2014 sampling results exceed MOECC Procedure D-5-5 objectives, but are within the maximum reasonably treatable concentrations as outlined in MOECC Procedure D-5-5. A discussion of specific water quality parameters identified at levels exceeding the comparison standards is provided as follows. Hardness Hardness is an aesthetic water quality parameter. The hardness levels obtained for all test wells on the proposed development property and two existing water supply wells tested for the Heron Lake Estates subdivision exhibited hardness concentrations greater that the ODWS operational guideline of 100, but are less than the Procedure D-5-5 objective of 500. Observed hardness values for test well samples collected in 2014 ranged from 250 at TW4 to 360 at TW2. Hardness concentrations obtained for the wells tested within Heron Lake Estates also fall within this range. Elevated hardness at these measured concentrations can be easily addressed through conventional water softener/conditioner treatment to prevent scaling of plumbing fixtures. A separate untreated water line is recommended for water used for consumption since a water softener using sodium chloride brine will boost sodium levels in the water supply. Microbiological Parameters The 2014 groundwater quality results associated with test well TW1 indicate the ODWS standard of 0 ct/100 ml was exceeded for the 3 hour sample (13 ct/100 ml) and the 6 hour sample (1 ct/100 ml). The water quality sampling data from Paterson, 2009b reports 0 ct/ml at this time. As noted previously in this report, TW1 has artesian flow conditions and at a pumping rate of 30.3 L/min for six hours the well continued to have artesian flow. Although each well was shock chlorinated prior to aquifer testing and sample collection, the strong artesian flow conditions at TW1 did not permit the maintenance of a chlorine residual in this well for any length of time. It is concluded based on satisfactory results from other test wells and historical results for TW1 that a potable supply can be constructed. If TW1 cannot be properly shock chlorinated and/or if further pumping of the well does not produce an acceptable Page 16 WESA

20 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 microbiological sampling result, the well should be sealed and abandoned and an alternate well supply be constructed. Total Dissolved Solids (TDS) Test well TW2 was the only well location to exceed the ODWS standard of 500 for total dissolved solids (TDS). TDS levels of 554 after 3 hours of pumping and 518 after 6 hours of pumping were obtained. TDS is an aesthetic objective (i.e. not health-related) and is of concern regarding potential corrosion of plumbing fixtures at levels above 500 and can be an indicator of mineralized water. The term total dissolved solids refers mainly to the inorganic substances dissolved in water, the principal constituents being chloride, sulphate, calcium, magnesium and bicarbonates. At TW2, concentrations of each of these parameters were marginally elevated but still well below their respective ODWS standards. When compared to the TDS results associated with other on-site test wells, as well as adjacent water supply wells, the results for TW2 indicate that groundwater below 27 m bgs is potentially susceptible to elevated TDS concentrations. Of note, the measured TDS for TW2 decreased by 36 over 3 hours and further pumping may reduce the level below the ODWS standard. Iron Slightly elevated iron concentrations were measured above the applicable ODWS criteria at all test well and adjacent water supply wells, with the exception of TW4. Iron is an esthetic (not a health-related) parameter and at the measured concentrations (<1 ), can be readily treated in conjunction with hardness through the use of conventional water softeners or treated on its own through various commercially available iron removal system, as stated within MOECC Procedure D-5-5. Turbidity Lab turbidity was measured at concentrations greater than the applicable ODWS aesthetic objective of 5 NTU at test wells TW2 and TW3 as well as at both water supply wells from the adjacent Heron Lake Estates subdivision. Field turbidity was measured at above 5 NTU only at test well TW2. As per MOECC Procedure D-5-5, elevated turbidity can represent an indicator of poor well construction. Although turbidity is not a health-related parameter in itself, particular attention should be given to bacteriological parameters where elevated turbidity is present. There were no ODWS criteria exceedances for bacteriological parameters measured at TW2, TW3 or both water supply wells which had elevated turbidity. Turbidity levels measured at test wells TW2 and TW3 were observed to decrease as pumping continued, most notably at TW2, to concentrations marginally exceeding the applicable criteria. The discrepancy between laboratory and field turbidity values is attributed to iron precipitation in laboratory samples after sample Page 17 WESA

21 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 collection. As indicated previously, iron was identified at levels exceeding the comparison standards for all sample location with the exception of TW4. Summary The results from the groundwater supply assessment for the proposed subdivision development indicate that well water supplies with acceptable water quantity and water quality can be obtained for the residences and commercial properties in the proposed development. The only observed water quality issues are of an operational or aesthetic nature related to hardness, TDS, iron (marginal) and turbidity (marginal). The hardness and iron issues can be addressed as needed through the installation of conventional water softeners (or manganese greensand filters where only iron is an issue). The removal of iron through treatment will result in reduced turbidity levels in water supplied to the end user. To reduce concerns related to slightly elevated TDS concentrations, water supply wells are recommended to be constructed no deeper than 27 m bgs. Water quality analytical results for the wells that have been tested are not considered indicative of GUDI (groundwater under direct influence of surface water) well conditions. This conclusion is supported by the strong artesian bedrock aquifer conditions that suggest no hydraulic connection between the bedrock aquifer and the Jock River located several metres lower in elevation compared to the proposed development property. 3.0 DESIGN RECOMMENDATIONS The following sections outline recommendations for well and septic system design for the proposed development. It is the purpose of this report to assess development feasibility at the proposed density. Recommendations are based on proposed four-bedroom homes privately serviced by individual wells and Class 4 type sewage systems. A discussion of recommended procedures for well and septic system construction is also included. 3.1 LOT SIZE AND DRAINAGE The proposed development involves the subdivision of approximately 22 hectares (Ha) into 16 residential lots and 5 commercial lots with a minimum lot size of 0.8 Ha (Figure 2). The average lot size for the proposed development is on the order of 0.95 hectares. Drainage has not been identified as a key concern for the proposed development given site relief and natural drainage towards the Jock River. Shallow water levels measured within the overburden wells TW5 to TW7 suggest a perched or seasonally perched water table within the shallow overburden Page 18 WESA

22 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 unit. Drainage improvements along access roadways should further reduce any impacts on residence, septic system and well placement due to seasonal high water table conditions. The proposed residential lot sizes are considered sufficient for a privately serviced 4-bedroom residence with a conventional fully raised leaching bed sewage system, which is typically designed for a hydraulic loading of up to 3000 L/d. The proposed commercial lots are considered sufficient for septic systems where maximum design hydraulic loadings are no greater than 4,500 L/d and where the wastewater produced from the establishment consists solely of sewage of domestic use origin. 3.2 WELL DESIGN The construction of water supply wells must, as a minimum, comply with the specifications of Ontario Reg. 903 (and subsequent amendments), and municipal requirements, if any. Based on the results from the hydrogeological investigation described within Sections 2.1 to 2.5 above, the limestone bedrock aquifer is characterized by suitable quantity and quality for the construction of water supply wells throughout the proposed subdivision at depths of up to approximately 27 m bgs. However, it should be noted that flowing artesian well conditions are expected to occur throughout the site. In order to meet the applicable regulatory requirements described within O.Reg 903, it is recommended that flowing packer systems be installed within each well. The purpose of these systems is to prevent the occurrence of uncontrolled flow discharging above the top of the well casing to the ground surface, which may compromise the integrity of the well. Conventional flowing packers can be lowered into the well casing upon well completion and are typically installed above the pitless adaptor, which should be installed below the frost line at a minimum of 1.5 m bgs. Where bedrock is encountered at depths above 1.5 m bgs, it may be necessary to import additional fill to attain the necessary depth for the pitless adaptor and discharge line alternatively to trenching bedrock from the well to the residence. Figure 6 shows a typical recommended well design with a conventional flowing well packer system. An example brochure of a flowing packer system that would be suitable for use within the proposed subdivision is included as Appendix G. The annular space between the well casing and the drilled hole should be sealed with high early strength cement grout, prepared with 4% bentonite. The objective of the procedure is to prevent contamination of the bedrock aquifer via infiltration through the well annular space. Further to this, Ontario Reg. 903 (as amended by O.Reg. 128/03) now requires the well contractor to install a suitable sealant around the base of the well casing where it intersects the bedrock. The following recommendations provide additional measures to ensure a water supply well is protected from surface derived contaminants: Page 19 WESA

23 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 a. A 25.4 cm (10 in.) diameter hole should be drilled through the overburden and at least 1 m (3.3 ft.) into competent (i.e. un-weathered) bedrock. b. New steel casing, 15.3 cm (6 in.) in diameter, should be installed in the drilled hole. Casing must be a minimum of 6 m in length. c. Ontario Reg. 903 well placement requirements and grouting procedures should be followed to ensure that surface derived contaminants cannot enter the well. d. When the grout has set (24 hours for quick set cement, 72 hours for a regular cement), drilling can continue until a suitable water supply is obtained. The cement must be dry before drilling is continued. Disturbance of partially set grout can either cause fractures to form in the grout, or separation between the grout and the bounding materials. This could create a pathway for contamination between the overburden and the bedrock aquifer. e. Wells should be completed with a vented well cap and pitless adaptor, and casing must extend at least 40 cm (16 inches) above ground surface. It is recommended that newly constructed wells be pumped for a minimum of 12 hours after construction to ensure adequate well development and to reduce groundwater turbidity to acceptable levels before connection to the residences plumbing system. The installation of conventional groundwater heat pumps is potentially feasible within the proposed subdivision based on the available flow information and assessed aquifer transmissivity. Any open loop system design would need to accommodate the artesian flow conditions on site which can be problematic with freezing during winter months. Based on the available information collected throughout the hydrogeological investigation, it is recommended that on-site test well TW1 be abandoned due to potential deficiencies in well integrity and well maintenance, which likely resulted in some water quality degradation over time as noted within Section 2.5. It is not recommended that these test wells be re-purposed as water supply wells for residences within the proposed subdivision. Furthermore, shallow overburden test wells TW5 to TW7 should also be abandoned. The well abandonments should be carried out in accordance with O. Reg. 903 by an MOECC licenced well contractor. 3.3 SEPTIC SYSTEM DESIGN Class 4 sewage systems should be constructed on each lot according to the Ontario Building Code (2012). The Code and Guide for Sewage Systems stipulates that a separation of 0.9 m (2.85 ft.) must exist between the bottom of the absorption trenches or filter surface and any underlying impermeable material and/or the highest seasonal water table. Consequently, a terrain unit characterized by a minimum overburden material thickness of 1.5 m with suitable permeability Page 20 WESA

24 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 and percolation times that is not intersected by the highest seasonal water table is required for the construction of in-ground septic beds. Based on the general requirements discussed above, fully raised tile beds are necessary for all lots situated within the fine sand/silt over bedrock (SM/BR) and clayey silty sand over bedrock (SC/BR) terrain units as the required soil thickness is not available for in-ground beds and perched groundwater levels shallower than 1.5 m bgs were observed within the overburden test wells. In-ground or partially raised beds may be constructed for lots which are located within the clayey silty sand (SC) terrain unit based on generally acceptable percolation times, soil thickness and overburden groundwater levels. However, spring (high flow) water table data would need to be collected since it is possible that the water table may rise to less than 1.5 mbgs in these areas following the spring freshet or heavy rainfall events. Furthermore, percolation tests on individual lots to assess their suitability would also be required in conjunction with a lot-specific engineered design before construction approvals can be obtained. Fully raised tile bed construction is shown for all lots on the Lot Development Plan on Figure 7 to show that all lots are adequate in size to permit this type of tile bed design. The construction of these beds will require the use of imported fill with a percolation time of 10 min/cm. Note: a 10 minute/cm percolation time is used so that the clearances to structures data in table B of the 2012 OBC can be used. If a T time of less than 10 minutes is used, then the distances must be increased. In order to meet the OBC requirements, the distribution pipes must be 0.9 metres above the highest expected water table level, it may be necessary to import additional fill to attain the necessary elevation for the distribution lines. The topsoil over the tile bed area must be stripped away and the fill should be placed over the bedrock or unacceptable soil such that a minimum of 0.9 metres separates the bottom of the absorption trenches and the bedrock or unacceptable soil surface. A minimum thickness of 0.3 metres of stone must be used for the absorption trench which is overlain by a minimum 0.3 m of additional sand fill. The total height of the leaching bed mound will be 1.5 metres from the bedrock, unacceptable soil surface, and water table. The side slopes of the leaching bed mound will be shaped to shed water and the slope shall not be greater than one unit vertically to 4 units horizontally. In locations where an acceptable unsaturated topsoil is less than 0.25 metres thick, fill will be required to ensure that an unsaturated mantle 0.25 metres thick extends for 15 metres down gradient from the outer distribution pipe. The Building Code states that the minimum total length of distribution pipe is determined by the following formula: Page 21 WESA

25 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 where: L = QT 200 L = total length of distribution pipe (m) Q = total daily design sanitary sewage flow (L) T = the design percolation time (min/cm) The design sanitary sewage flow for a four-bedroom dwelling in the proposed subdivision development is assumed to be 3000 L/d, which is 1000 L/d more than the value listed in the 2012 Ontario Building Code and will allow for additional plumbing fixtures to be used. Based on the above equation, the minimum total length of distribution pipe for a raised bed with an imported fill T time of 10 minutes/cm is 150 metres. The approximate footprint of the leaching bed lateral pipes, based on design regulations in the Ontario Building Code and a total distribution pipe length of 150 m, is 240 m 2 (i.e. 10 lengths of 15 m). The approximate footprint of a fully raised leaching bed with 1:4 side slopes and mantle is 1000 m 2. For the purposes of this investigation, the maximum daily sanitary sewage flow associated with the proposed commercial lots is set at 4,500 L/day. This flow rate is considered adequate for most potential commercial operations that may be proposed for these lots. A calculation made based on a conventional fully raised system design (formula provided previously) indicates that the minimum total length of distribution pipe for a raised bed with an imported fill T time of 10 minutes/cm and a maximum daily flow rate of 4,500 L/d is 225 metres. The approximate footprint of the leaching bed lateral pipes, based on design regulations in the Ontario Building Code and a total distribution pipe length of 225 m, is 360 m 2 (i.e. 12 lengths of m). The approximate footprint of a fully raised leaching bed with 1:4 side slopes and mantle is 1200 m 2. Wherever possible, leaching beds should be located down gradient from any nearby wells or surface water bodies. Site specific percolation tests will be required for installation of partially raised or in-ground leaching bed systems. For most municipalities, an engineer approved design is required for any system design other than a fully raised tile bed system. The Building Code stipulates minimum clearances for in-ground and raised tile beds. Table 5 gives clearances for the various types of beds that may be constructed within the proposed subdivision.

April 2015 Table 5: Tile Bed Clearances Surface Feature Water supply well with a watertight casing to a depth of 6 m Any other water supply well (including dug wells) Minimum Clearance (m) In-ground Partially Raised Fully Raised Surface water body Structures Lot boundaries The attached lot development plan (Figure 7) has been produced with a fully raised tile bed design, showing that fully raised beds (i.e. the bed design with the largest space requirements) with capacity of 3000 litres/day can be constructed on each residential lot and 4500 litres/day systems can be constructed on each commercial lot. Please note that this plan does not preclude the installation of partially raised beds, in-ground beds or small footprint systems if appropriate site conditions exist. Any septic system design other than a conventional fully raised bed system must be determined on a lot by lot basis and in conjunction with any additional approval requirements from local inspectors. With respect to the commercial lots it is a recommendation that systems with tertiary treatment be required, providing the benefit of a smaller septic system footprint while being protective any potential impacts to the Jock River. The proposed location of water supply wells and septic systems is based on assumed residence locations. WESA recognizes that the final placement of water supply wells and septic systems will depend on the location of each residence and will be adjusted accordingly. It is important to ensure that septic systems are placed at appropriate distances from the surface features listed in Table 5, and down gradient of domestic water supply wells. 4.0 IMPACT ASSESSMENT FOR SUBSURFACE SEWAGE The MOECC requires that an impact assessment be performed for proposed developments that are to be serviced by individual subsurface sewage systems in non-designated areas. The purpose of this study is to protect the environment and public health by ensuring that the development utilizing subsurface sewage systems proceeds at a density and scale that will not result in, or cause degradation of, groundwater resources in exceedance of acceptable limits (MOECC, 1995). The following impact assessment is based on the site specific physical setting of the site as outlined in this report and the hydrogeological investigation performed. This impact assessment is based on the MOECC s Procedure D-5-4: Technical Guideline for Individual On-Site Sewage Systems: Water Quality Impact Risk Assessment (last revision August 1996) (MOECC, 1995). Page 23 WESA

27 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April GENERAL EVALUATION The subject property associated with the proposed subdivision is located on Part of Lots 7 and 8, Concessions IV, former Township of Goulbourn, now the City of Ottawa, Ontario (Figure 1). No municipal water or sewage systems are available or planned for this area. The proposed development complies with Ontario Regulation 358 in that holding tanks will not be used to store sewage. Recommendations pertaining to individual sewage system design based on the Building Code have been previously discussed in Section 3.0 of this report. Background nitrate-nitrogen levels in groundwater were determined from groundwater samples collected in fall of 2014 from overburden test well TW7, as well as bedrock test wells TW1 to TW4, which are each located on the proposed development. The analytical results indicated that nitrate concentrations were below laboratory detection limits (<0.01 ) for all sampling locations, which is well below the Ontario Drinking Water Standards (ODWS) maximum allowable concentration of 10. All other nitrogen forms (inorganic ammonia and nitrite, and organic total Kjeldahl nitrogen) were also non-detect or detected at low levels well below the ODWS standards prescribed. Nitrate concentrations measured within the active domestic water supply wells located within the adjacent Heron Lake Estates subdivision were also below laboratory detection limits. Since the adjacent subdivision is characterized with comparable development density and anticipated well construction as the proposed Riverbend subdivision, nitrogen impacts are not anticipated to be of notable concern for the proposed new development as it relates to drinking water quality. It is thought that the low levels of nitrogen compounds detected result from small amounts of naturally-occurring organic material present in the groundwater. Based on the results of the Mississippi Valley Source Protection Area Highly Vulnerable Aquifer (HVA) mapping study (Golder, 2003), the site is situated within the area identified as being associated with a highly vulnerable aquifer on a regional scale. However, the results of the hydrogeological assessment presented herein indicate the proposed development site is not located in a hydrogeologically sensitive area. There were no notable exposures of fractured bedrock observed across the site. The overburden material is not considered highly permeable (generally clayey/silty fine sands). Although soil cover thickness was observed to be highly variable (between 0.6 and 3.4 m thick), it is inferred that the bedrock surface and upper bedrock unit represent a hydraulic boundary isolating the perched groundwater within the overburden material from the bedrock water supply aquifer. This determination is supported by the strong upward vertical groundwater flow gradient and confining aquifer conditions which have been identified as protective of the bedrock aquifer in this site assessment. Page 24 WESA

28 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 At least 2.0 m of native overburden materials containing some clay (Figure 5) was observed for those proposed lots in closest proximity and/or adjacent to the Jock River (Blocks 19 to 21 and Lots 8 to 10). These soil conditions are considered acceptable in mitigating any potential input to the Jock River from the onsite sewage systems. The Riverbend Golf Course is an active golf course, located adjacent to the proposed subdivision, represents a potential source of nitrate or nitrogen due to the potential use of fertilizers. However, based on the low background nitrate-nitrogen levels identified within the groundwater samples and the hydrogeological characteristics of the subject property, groundwater at the site is not believed to be susceptible to contamination. 4.2 THREE STEP ASSESSMENT PROCESS As per Procedure D-5-4 every proposed development involving individual on-site sewage systems requires an assessment of the groundwater impact potential to ensure that the combined effluent discharges from all the individual on-site sewage systems in a development will have a minimal effect on the groundwater and the present or potential use of the adjacent property. For the purposes of the assessment, the ODWS of 10 for nitrate as nitrogen is used as an indicator of groundwater impact potential. The assessment involves a three step process, with the need to advance to the next step dependent upon on the conditions defined in the previous step. Page 25 WESA

29 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 Step One: Lot Size Considerations The average lot size for the proposed development is on the order of 0.95 hectares, with a minimum lot size of 0.8 Ha. As previously discussed in Section 4.1, the site is not considered hydrogeologically sensitive. However, based on the average size of the lots, system isolation considerations should be evaluated based on the requirements of Procedure D-5-4. As discussed in Section 3.3, the lot development plan recommends that leaching beds be located down gradient of adjacent wells and property boundaries and that the separation distance between individual on-site systems be maximized in order to optimize the attenuative capabilities of each lot. Step Two: System Isolation Considerations Based on findings from the drilling and excavation program, the most probable groundwater receiver for sewage effluent is considered to be limited to the shallow overburden deposits. The overburden material is not considered highly permeable (generally clayey/silty fine sands) and there were no notable exposures of fractured bedrock observed across the site. Although soil cover was observed to be highly variable (between 0.6 and 3.4 m thick), it is inferred that the bedrock surface and/or upper bedrock unit represents a sufficient hydraulic boundary isolating the perched groundwater within the overburden material from the deep bedrock water supply aquifer. This determination is supported by the relatively strong upward vertical gradients and confining aquifer conditions identified by the measured baseline water levels. The lower hydraulic or physical boundary of the groundwater receiving the sewage effluent is considered to be the upper bedrock surface or upper metre of the bedrock unit, which is encountered at depths ranging between 0.6 and 3.4 m bgs. As discussed in Section and 2.4.2, major water bearing zones were generally encountered on a regional scale (based on MOE well records) at depths between 10 and 45 m bgs, and on a local scale (based on the onsite drilling program) between 15 and 28 m bgs, which suggests that the uppermost water supply aquifer boundary is expected to be found between approximately 10 and 20 m bgs. There is no evidence to suggest that that the upper bedrock zone is significantly fractured or represents a potential water supply aquifer. Based on the above observations, the proposed groundwater resource will be separated from the Class 4 sewage systems by at least 10 to 20 m of competent bedrock. Sewage effluent is considered to be hydrogeologically isolated from the existing supply aquifer based on the reasons outlined above. The higher static pressure within the bedrock aquifer compared to the overburden water table at the site is considered protective of any downward migration of Page 26 WESA

30 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 potential impacts derived near surface. Therefore, the deep bedrock aquifer that will be intersected by future water supply wells, as recommended within Section 3.2, is not considered to be notably sensitive. This conclusion is corroborated by the absence of nitrate impacts observed within the water quality results associated with existing water supply wells sampled as part of this investigation and located within the adjacent Heron Lake Estates subdivision, which is characterized with a comparable development and well density as the proposed Riverbend subdivision. The Jock River represents a potential surface water receptor in some areas of the proposed subdivision, however leaching beds are to be located at a sufficient distance (>18 metres) away as per Table 5 and the applicable regulations. This will ensure that sewage effluent does not enter the watercourse with nitrate-nitrogen concentrations greater than 10. In addition, it is recommended that leaching beds be located down gradient of adjacent wells and that the separation distance between individual on-site systems be maximized in order to optimize the attenuative capabilities of each site. Assuming the recommendations made herein are followed in conjunction with meeting the applicable guidelines and regulations (O. Regs. 358 and 903), the potential for notable adverse impacts, as defined as nitrate concentrations in exceedance of 10, to the Jock River as a result of the proposed septic system operations is low. Therefore, it is WESA s professional opinion that the requirements of step two of the assessment process described within Procedure D-5-4 are met and Step 3 of the assessment is not required. With respect to the commercial lots it is a report recommendation that systems with tertiary treatment be required, providing the benefit of a smaller septic system footprint while being protective any potential impacts to the Jock River. Based on the findings of this groundwater impact assessment it is our opinion that the sewage effluent from the proposed onsite septic systems is hydrogeologically isolated from the water supply aquifer utilized by onsite and adjacent water supply wells. 5.0 SUMMARY AND CONCLUSIONS A terrain analysis and hydrogeological investigation was completed for the proposed Riverbend Mixed Use Subdivision located on Part of Lots 7 and 8, Concessions IV, former Township of Goulbourn, now the City of Ottawa, Ontario (Figures 1 and 2). The purpose of the study was to assess the suitability of the property for development of 16 residential and 5 commercial lots to be individually serviced. Information was gathered through a combination of background research and onsite investigations. Page 27 WESA

31 CB Terrain Analysis and Hydrogeological Assessment Proposed Riverbend Mixed Use Subdivision Westboro Mortgage Investment Corp. April 2015 The on-site overburden material was characterized throughout the site based on the background data review as well as on-site drilling and excavation programs completed by Paterson in 2009 (Paterson, 2009b) and by WESA in The overburden thickness was determined to be variable across the site and ranging between 0.6 and 3.4 metres, while the overburden material was generally classified as fine sand/silt or clayey silty sand. The resulting information was compiled to reveal three major terrain units for the proposed subdivision property. These consisted of a fine sand/silt over bedrock (SM/BR) unit; a clayey silty sand (SC) unit; and clayey silty sand over bedrock (SC/BR) unit. Four bedrock test wells were drilled by Paterson in 2009 and were constructed similarly to water supply wells located in the adjacent existing subdivision based on the available MOECC well records. WESA conducted 6-hour pumping tests at 8 USGPM on all four test wells, in conjunction with groundwater sample collection. The results revealed that the water quantity and quality associated with the bedrock aquifer encountered at depths of up to 27 metres below ground surface (m bgs) is suitable to be used for residential and/or small scale commercial drinking water supply. It is recommended that all newly constructed wells for the proposed subdivision be constructed as indicated within Figure 6. The use of flowing packers (such as the Well Buster) is recommended where flowing artesian well conditions are observed in order to satisfy the requirements of O.Reg Furthermore, it is recommended that newly constructed wells be pumped for a minimum of 12 hours after construction to ensure adequate well development and to reduce groundwater turbidity to acceptable levels before connection to the residences plumbing system. In the event that test well TW1 cannot be properly shock chlorinated and/or if further pumping of the well does not produce an acceptable microbiological sampling result, it is recommended that test well TW1 not be re-purposed as water supply wells for residences within the proposed subdivision and that TW1 be sealed and abandoned in accordance with O. Reg. 903 and a replacement well be constructed for supply. Several recommendations for private services, including well design and sewage systems, have been included in this report. These recommendations are based on the Ontario Building Code (2012) and all applicable regulations, guidelines, policies, and procedures, as well as results of the field investigations. A groundwater impact assessment was performed for the site, based on MOECC Procedure D-5-4. The results of this assessment indicate that there will be no adverse impact to the groundwater resource on property or off property with the proposed private sewage system servicing of the development.

All methodologies comply with this document and are validated for use in the laboratory. The methods and techniques employed in this analysis conform to the performance criteria (detection limits, accuracy and precision) as outlined in the Protocol for Analytical Methods Used in the Assessment of Properties under Part XV.1 of the Environmental Protection Act. The CWS PHC methods employed by Maxxam conform to all prescribed elements of the reference method and performance based elements have been validated. All modifications have been validated and proven equivalent following the 'Alberta Environment Draft Addenda to the CWS-PHC, Appendix 6, Validation of Alternate Methods'. Documentation is available upon request. Maxxam has made the following improvements to the CWS-PHC reference benchmark method: (i) Headspace for F1; and, (ii) Mechanical extraction for F2-F4. Note: F4G cannot be added to the C6 to C50 hydrocarbons. The extraction date for samples field preserved with methanol for F1 and Volatile Organic Compounds is considered to be the date sampled. Maxxam Analytics is accredited for all specific parameters as required by Ontario Regulation 153/04. Maxxam Analytics is limited in liability to the actual cost of analysis unless otherwise agreed in writing. There is no other warranty expressed or implied. Samples will be retained at Maxxam Analytics for three weeks from receipt of data or as per contract. * RPDs calculated using raw data. The rounding of final results may result in the apparent difference. (1) This test was performed by Maxxam Analytics Mississauga (2) Dissolved Organic Carbon (DOC) present in the sample should be considered as non-purgeable DOC. (3) Values for calculated parameters may not appear to add up due to rounding of raw data and significant figures.
