1 Mr. Dan Emerson Construction Manager BRE Properties, Inc Shellmound Way, Ste. A Emeryville, CA ARCADIS U.S., Inc El Camino Real Suite D-21 Los Altos California Tel Fax Subject: Letter Report for the Phase II Environmental Site Assessment at 640 Veterans Boulevard, Redwood City, California ENVIRONMENT Dear Mr. Emerson: ARCADIS is pleased to submit this letter report to BRE Properties Inc. (BRE) describing the subsurface investigation conducted at the former Dodge Dealership located at 640 Veterans Boulevard, Redwood City, California (the Site). The Site is currently vacant and is comprised of one parcel that is3.63 acres in area. The Site is located in a mixed commercial and residential area. A Site Vicinity Map and Site Map are presented as Figures 1 and 2, respectively. This subsurface investigation included advancing eleven temporary soil borings and five temporary soil-vapor probes to further assess the potential presence of chemicals of potential concern (COPC) at the Site. A description of these activities and our assessment of the findings are provided below. : August 12, 2010 Contact: Chuck Pardini Phone: Chuck.pardini@arcadis-us.com Our ref: LC SITE BACKGROU The Site was formerly occupied by several automotive dealerships and contains four buildings which were constructed in the 1960s. These buildings are referred to as Buildings A through D. The former Site included offices, a showroom, vehicle service stations, car wash bays, an equipment room, a body shop, and a paint booth. Reportedly, two underground storage tanks (USTs), four aboveground storage tanks (ASTs), ten underground hydraulic hoists, two oil/water separators, one sump, and several chemical storage areas were used at the Site during the former automotive dealership operations. Reportedly, the two USTs were removed in 1988, and the underground hydraulic hoists were removed and replaced with eleven aboveground hoists (EarthTech, 2004). The exterior portions of the Site consist of asphalt-paved parking lots and driveways. According to the EarthTech 2004 report, seven groundwater monitoring wells (DC1 c:\documents and settings\lschan\local settings\temporary internet files\content.outlook\a8frgt6f\bre redwood city phase ii_vf (2).docx

2 Mr. Dan Emerson August 12, 2010 through DC7) were previously installed at the Site. However, neither the date of the well installation nor the purposes of the monitoring wells was provided to ARCADIS for review. ARCADIS noted five of the reported seven groundwater monitoring wells (DC1 through DC5) at the Site. These wells were found to be abandoned and sealed. The monitoring wells had been installed by others and EarthTech sampled four of the seven groundwater monitoring wells during previous groundwater investigations in 2004 (EarthTech, 2004). The results of this testing is discussed further below. A subsurface investigation was conducted at the Site by EarthTech, Inc. in Eight soil borings were advanced to depths up to approximately 10 feet below ground surface (bgs) for the collection of soil samples. In addition, four previously existing groundwater wells were sampled. According to the EarthTech Phase I Environmental Site Assessment and Limited Phase II Site Investigation Report dated June 2004, groundwater sampling results indicated limited or no impact, with the exception of the sample collected from well DC5, located in the eastern portion of the Site. The groundwater sample collected from well DC5 contained an estimated concentration of 340 micrograms per liter (ug/l) of total petroleum hydrocarbons as diesel (TPHd). Previous soil sampling results identified relatively low concentrations of hydrocarbon constituents near the oil/water separators and in the exterior chemical storage area located on the southeast side of Building D. Also, ethylbenzene and methyl tertiary butyl ether (MTBE), common gasoline additives, were detected in the car wash bay locations (EarthTech, 2004). According to the ARCADIS Phase I Environmental Site Assessment report conducted on July 22, 2010, previous soil sampling events have indicated low concentrations of hydrocarbon constituents near the oil/water separators in Buildings B and D and in the exterior chemical storage area located on the southeast side of Building D. Therefore, the potential impact to the soil and groundwater beneath the Site resulting from the former Site operations is identified as an environmental concern. In addition, the oil/water separators and the potential underground hoist observed in Buildings B and D should be removed in accordance with regulatory guideline (ARCADIS, 2010). The purpose of ARCADIS investigation was to assess the presence and magnitude of COPCs resulting from the former operations at the Site. 2.0 SITE HYDROGEOLOGY The direction of groundwater flow is reported to be to the east (Conestoga-Rovers & Associates, 2010).The lithology beneath the Site, based on the soils encountered in C:\Documents and Settings\lschan\Local Settings\Temporary Internet Files\Content.Outlook\A8FRGT6F\BRE Redwood City Phase II_vF (2).docx Page: 2/14

3 Mr. Dan Emerson August 12, 2010 the eleven soil borings, consists primarily of clayey sands and sandy clays to a depth of approximately 3 feet bgs; clays and silty clays from approximately 3 to 10 feet bgs; and interbedded clayey sands, clayey silts, and silty clays from approximately 10 to 28 feet bgs. Groundwater was first encountered between approximately 10 and 14 feet bgs in borings B-2 and B-10, but was also first encountered at a specific location at depths as great as 22 feet in boring B INVESTIGATION METHODOLOGY To facilitate assessment of the possible presence of COPCs, soil, soil-vapor, and groundwater samples were collected on July 29 and 30, This Section describes the methodologies used for the subsurface investigation tasks performed at the Site. 3.1 Pre-Field Activities Prior to subsurface field activities, ARCADIS submitted the appropriate subsurface drilling permit application and obtained the subsurface drilling permit from the San Mateo County Environmental Health Services Division (SMCEHS). ARCADIS notified the SMCEHS two days prior to commencing drilling activities. ARCADIS prepared a Site-specific health and safely plan (HASP) for use by our employees, a copy of which was available to subcontractors for reference. ARCADIS also marked the Site and notified Underground Service Alert (USA) three days in advance of the work and subcontracted a private utility locator, Cruz Brothers Locators Inc. (Cruz), to identify possible subsurface utilities that may be in the vicinity of the proposed soil borings and soil-vapor probe locations. Copies of the HASP and drilling permit were retained on site at all times during the field activities. The fieldwork was monitored to ensure that appropriate health and safety procedures were followed. No health and safety related problems were encountered during the field activities. 3.2 Boring Advancement On July 29 and 30, 2010, ARCADIS contracted PeneCore Drilling (PeneCore) to advance eleven soil borings, B-1 through B-11, throughout the Site. The boring locations were selected in consideration of the former uses in specific areas of the C:\Documents and Settings\lschan\Local Settings\Temporary Internet Files\Content.Outlook\A8FRGT6F\BRE Redwood City Phase II_vF (2).docx Page: 3/14

4 Mr. Dan Emerson August 12, 2010 Site. In addition, PeneCore advanced five boreholes within the former paint booth and paint shop locations for the soil-vapor survey Boring Locations Eleven direct push soil borings (B-1 through B-11) were advanced at the Site. Following is the rationale for each sampling location: Two soil borings, B-1 and B-5, were advanced in the vicinity of the former oilwater separators and soil samples were collected at approximate depths of 5 and 10 feet bgs. One additional surface soil sample was collected at an approximate depth of feet bgs from soil boring B-1 due to the strong hydrocarbon odor noted during advancing this boring. Five soil borings, B-2, B-3, B-4, B-6, and B-7, were advanced in the vicinity of the former locations identified as chemical and/or drum storage areas. samples were collected near the ground surface (approximately 1 to 2 feet bgs), as well as at approximate depths of 5 and 10 feet, to assess the presence of COPC. Two soil borings, B-8 and B-9, were advanced in the vicinity of the former underground hoists and soil samples were collected at approximate depths of 5 and 10 feet bgs. The 10-foot samples were collected at that depth because that depth is presumed to be below the depth of the bottoms of the former hoists. One soil boring, B-10, was advanced in the former UST area and soil samples were collected at approximate depths of 5 and 10 feet bgs. The 10- foot samples were collected at that depth because that depth is presumed to be below the depth of the bottoms of the former USTs. One soil boring, B-11, was advanced near the pad-mounted transformer and soil samples were collected at the surface and approximately 5 feet bgs to assess the potential presence of polychlorinated biphenyls (PCBs). Five soil-vapor borings, SG-1 through SG-5, were advanced to an approximate depth of 5 feet bgs in the former paint shop and paint booth areas located in the northwestern portion of the Site.

5 Mr. Dan Emerson August 12, 2010 Three soil borings (B-2, B-7, and B-10) were drilled to a depth where first encountered groundwater is reached and groundwater samples were collected at B-2-W, B-7-W, and B-10-W, respectively. Groundwater was first encountered between approximately 10 and 14 feet bgs in borings B-2 and B-10, but was also first encountered at depths as great as 22 feet in boring B-7. The approximate locations of the soil borings are shown on Figure Boring Advancement and Sample Collection The first five feet at each soil boring location was cleared using a hand auger. The soil boring was then advanced with a direct push drilling rig to the desired depth, under the supervision of ARCADIS field staff working under the direction of a State of California-registered Professional Geologist. Three soil borings (B-2, B-6, and B-7) were further advanced to approximate depths of between 13 and 15 feet bgs. The soil samples collected at depths between 13 to 15 feet bgs were analyzed for metals only. Also, three groundwater samples, B-2-W, B-7-W, and B-10-W, were collected from soil borings B-2, B-7, and B-10. These soil borings were advanced to approximate depths of between 15 and 28 feet bgs to collect the groundwater samples. cores were continuously collected in acetate sleeves for logging and potential sample collection. cores collected from each boring were visually and manually classified in accordance with the Unified Classification System (USCS) and Munsell color chart. The ARCADIS field staff noted and recorded the USCS and Munsell information, along with other notable sample features such as organic vapor concentrations obtained using a photoionization detector, field observations of staining, odors, or other soil characteristics, on field boring logs. samples collected for potential chemical analysis were collected in acetate sleeves, sealed with Teflon tape and plastic end caps, labeled, and placed in an ice-chilled cooler. After reaching the depth of groundwater in soil borings B-2, B-7, and B-10, a temporary well casing was installed to allow the collection of a grab groundwater sample. Prior to sampling, ARCADIS personnel measured the depth to groundwater in each boring. Groundwater samples were then collected from each boring with a C:\Documents and Settings\lschan\Local Settings\Temporary Internet Files\Content.Outlook\A8FRGT6F\BRE Redwood City Phase II_vF (2).docx Page: 5/14

6 Mr. Dan Emerson August 12, 2010 checked valve sampler and polyethylene tubing, and decanted into laboratorysupplied bottles that were sealed, labeled, and placed in an ice-chilled cooler. and groundwater samples selected for chemical analysis were transported to Torrent oratory Torrent oratory, Inc. (Torrent), a State of California Department of Health Services-certified laboratory for analysis. All samples were requested for a three-day turnaround time analysis. After advancing each soil boring to the total depth and collecting soil and grab groundwater samples, each soil boring was properly backfilled with neat cement grout on the same day as the borehole was advanced. Following completion of soil vapor sample collection activities, the sampling tube was removed from each probe. The bentonite and sand was cleared from each borehole, which was then properly backfilled with neat cement grout. cuttings and water used for cleaning were stored on site in 55-gallon California Department Of Transportation (DOT)-approved drums, pending profile, and will be disposed at an appropriately-permitted off-site facility. Two drums of soil and one drum containing water used for cleaning were generated during this investigation Vapor Survey On July 29, 2010, five temporary shallow soil-vapor probes were advanced, each to an approximate depth of 5 feet bgs. The probes were installed in general accordance with the Interim Final Guidance for the Evaluation and Mitigation of Subsurface Vapor Intrusion to Indoor Air published by the Department of Toxic Substances Control (DTSC) dated December 15, 2004 (Revised February 7, 2005). ARCADIS contracted PeneCore to perform the soil-vapor probe installation, under the supervision of ARCADIS field staff working under the direction of a State of California-registered Professional Geologist Vapor Probe Locations Five temporary soil-vapor probes (SG-1 through SG-5) were advanced to further assess the presence of volatile organic compounds (VOCs) in shallow soil vapor beneath the former paint booth and paint shop areas. The approximate locations of temporary soil-vapor probes are shown on Figure 3.

7 Mr. Dan Emerson August 12, Vapor Probe Installation and Sample Collection Upon reaching an approximate depth of 5 feet bgs at each probe location using a hand auger, a slotted sampling tube was inserted into the borehole. The borehole was filled with sand and topped with at least two feet of hydrated bentonite to inhibit surface air from entering the boring annular space. ARCADIS conducted the soilvapor sampling on July 30, 2010 after approximately 24 hours of equilibration. Each soil-vapor probe was purged of at least three casing volumes. The soil-vapor sample was then collected in the laboratory-supplied one-liter evacuated Summa canister at a approximate flow rate of 167 milliliter per minute (ml/min) using a flow regulator. A leak test was performed using isopropyl alcohol (IPA) as the leak check compound while sampling. After the sampling period was completed, the flow regulator was closed and sample collection ceased. Summa canister vacuum readings were documented at the beginning and end of each sample collection. The collected soilvapor canisters were then transported to Torrent for analysis of VOCs including the selected leak check compound by ed States Environmental Protection Agency (U.S. EPA) Test TO SUMMARY OF LABORATORY ALYTICAL RESULTS results for the recent soil, groundwater, and soil-vapor samples collected at the Site are summarized in Tables 1 through 4, respectively. The laboratory analytical reports and Chain-of-Custody documentation for the recent investigation are included in Appendix C. Summaries of the results from the investigation activities for soil, groundwater, and soil vapor are presented below. 4.1 A summary of VOCs and hydrocarbon analytical results for soil samples collected from the Site during this investigation is presented in Table 1. A summary of metals and PCBs analytical results is presented in Table 2. The soil analytical results are compared to the San Francisco Regional Water Quality Control Board (RWQCB) Environmental Screening Level (ESL), assuming the current or potential use of groundwater as a source of drinking water, Residential Exposure Scenario, and California Environmental Protection Agency (CalEPA) California Human Health Screening Levels (CHHSL) for residential land use.

8 Mr. Dan Emerson August 12, VOCs and Total Hydrocarbons Petroleum Hydrocarbons (TPH) Analyses boring B-1, located in the vicinity of the oil-water separator in the eastern portion of the Site, indicated the presence of TPH as gasoline (TPHg) at 3,400 mg/kg in the sample collected between approximately 1.0 and1.5 feet bgs, and at 510 mg/kg in the sample collected between approximately and 5.5 feet bgs. Both of these concentrations are above the TPHg ESL value of 83 mg/kg. However, TPHg was not detected in the deeper sample (approximately 10.0 to10.5 feet bgs) at the B-1 location. In addition, the polycyclic aromatic hydrocarbon (PAH) 2-methylnaphthalene was detected in soil boring B-1 at the 1.0 to 1.5-foot depth and the to 5.5 foot depth at concentrations of 3.4 mg/kg and 1.1 mg/kg, respectively. Both of these concentrations are above the ESL value for 2-methyl-naphthalene of 0.25 mg/kg. However, the PAH 2-methyl-naphthalene was not detected at the foot bgs in depth. boring B-7, located in the former drum/garbage storage area in the northwestern portion of the Site, indicated the presence of TPH as motor oil (TPHmo) at 620 mg/kg in the 1.0 to 1.5-foot sample. This concentration is above the respective TPHmo ESL value of 370 mg/kg. However, TPHmo was detected at a concentration of 9.2 mg/kg at the to 5.5-foot depth. None of the soil samples analyzed indicated the presence of VOCs above their respective regulatory screening levels during this subsurface investigation. Ethylbenzene and MTBE concentrations detected during the subsurface investigation in 2004 near the oil/water separators were not detected during this Phase II investigation Metals and PCB Analyses Antimony was detected in soil borings B-2 and B-4 at a depth of approximately 1.0 to 1.5 feet bgs at concentrations of 6.4 mg/kg and 12 mg/kg, respectively. The antimony concentrations detected in borings B-2 and B-4 were above its ESL value of 6.3 mg/kg, but below its CHHSL value of 30 mg/kg. Nickel was detected in soil borings B-8 and B-10 at a depth of approximately to 5.5 at concentrations of 210 mg/kg and 150 mg/kg, at or above the ESL value of 150 mg/kg but below the CHHSL value of 1,600 mg/kg. All other metal concentrations detected were below their regional background levels (LBNL, 2004), laboratory method detection limits, and/or their respective screening levels.

9 Mr. Dan Emerson August 12, 2010 Arsenic and vanadium were detected above their screening levels. However, the arsenic and vanadium concentrations were detected below their average background levels. Arsenic was detected at concentrations ranging from 2.5 mg/kg to 5.3 mg/kg, which is within the concentration range for naturally occurring arsenic of 0.6 mg/kg to 11 mg/kg (University of California-Riverside, 1996). Vanadium was detected at concentrations ranging from 20 to 160 mg/kg, which is within the concentration range for naturally occurring vanadium of 200 mg/kg. The three soil samples (B-2, B-6, and B-7) collected between approximately 13 to 15 feet bgs did not indicate the presence of metals at concentrations that are not expected to pose an environmental concern to the Site. PCB concentrations were not detected in soil boring B-11, located in the vicinity of the transformer, above the laboratory method detection levels and/or its respective regulatory screening levels. 4.2 Groundwater As shown in Table 3, the recent grab groundwater analytical results are compared to the ESLs for residential land use, assuming groundwater is a drinking water source. VOCs and TPH were not detected in any of the grab groundwater samples above analytical detection limits except MTBE. MTBE was detected in the B-2-W sample at 0.92 micrograms per liter (µg/l) and the B-10-W sample at 3.9 µg/l. The reported MTBE concentrations were below the corresponding ESL value of µg/l. TPHd concentration detected during the subsurface investigation in 2004 near the former underground hydraulic hoists location was not detected during this Phase II investigation Vapor results for the five temporary soil-vapor probes (SG-1 through SG-5) were advanced to further assess the presence of volatile organic compounds (VOCs) in shallow soil vapor beneath the former paint booth and paint shop areas. -vapor analytical results were shown and summarized in Table 4. The soil-vapor analytical results are compared to the ESL and the California Human Health Screening Levels (CHHSLs) developed by CalEPA for residential, for evaluation of potential vapor intrusion into future residential uses.

10 Mr. Dan Emerson August 12, 2010 The primary VOC detected in soil-vapor samples, benzene, was observed in the samples collected from all the sample locations, at concentrations ranging from 41.0 micrograms per cubic meter (µg/m 3 ) in SG-4 to 56.0 µg/m 3 in SG-3. All the soilvapor samples indicated benzene concentrations exceeding the corresponding CHHSL value of 36.2 µg/m 3. QUALITY ASSURANCE/ QUALITY CONTROL MEASURES ARCADIS implemented standard Quality Assurance/Quality Control (QA/QC) measures during the sample collection, transport, and chemical analytical process. The QA/QC measures consisted of evaluating laboratory performance of surrogate spike recovery, matrix spike/matrix spike duplicate (MS/MSD), method blank, and laboratory control spike (LCS) analyses. The primary objective of these QA/QC measures is to ensure that resulting analytical data are reproducible, are of adequate quality for their intended use, and are representative of actual conditions. IPA, the leak check compound, used during soil-vapor sampling was not detected in any soil-vapor samples. 6.0 UERGROU UTILITY ASSESSMENT Based on the utility locating results by Cruz, two rectangular shaped, metallic objects were identified and marked at the former USTs area. One rectangular shaped, metallic object was approximately 10 feet by 5 feet and the other one was approximately 5 feet by 3 feet. These rectangular metallic objects were detected at the former USTs area located in the southeastern portion of the Site. Although the former USTs were reportedly removed from the Site, the metallic objects identified at the former USTs locations during this investigation may indicate that the USTs potentially remain at the Site. Several other metallic features, possibly utility lines, were detected throughout the Site. 7.0 CONCLUSIONS A RECOMMEATIONS Previous soil sampling events have indicated low concentrations of hydrocarbons near the oil/water separators in Buildings B and D and in the exterior of the chemical storage area located on the southeast side of Building D. Therefore, on July 29 and 30, 2010, ARCADIS collected soil, groundwater, and soil-vapor samples across the Site to further assess the COPCs at the Site.

11 Mr. Dan Emerson August 12, 2010 The samples collected at soil boring location B-1, located in the vicinity of the oil-water separator in the eastern portion of the Site, suggest that surface soils have been impacted by TPHg at concentrations above ESLs. samples collected at an approximate depth of 10 feet bgs to 10.5 feet bgs, did not indicate TPHg at concentrations above the ESL. The PAH 2-methyl-naphthalene was also detected in soil boring B-1 at depths of approximately 1.0 to 1.5 feet bgs and to 5.5 feet bgs at concentrations above the respective ESL value. However, 2-methyl-naphthalene was not detected at the foot bgs in depth. Both TPHg and PAH concentrations were observed to decrease in the deeper samples at each location. The surface soil samples collected from boring B-7, located at the former drum/garbage storage area in the northwestern portion of the Site, indicated TPHmo above the TPHmo ESL. However, TPHmo was detected at a lower concentration at approximately to 5.5 feet, below the TPHmo ESL value. Therefore, it appears that the impacted soil appears to be limited to shallow soils. TPH and PAH concentrations detected within samples obtained from soil boring B-7 were below their laboratory method detection limits and/or their respective screening levels. Antimony and nickel concentrations were detected in four soil samples collected at the Site above their respective ESL values. However, the concentrations were present below their residential CHHSL values. The three deeper soil samples collected at between approximate depths of 13 and 15 feet bgs did not indicate the presence of metals at concentrations that are expected to pose an environmental concern to the Site. All other metal concentrations detected were below their regional background levels, laboratory method detection limits and/or their respective screening levels. None of the soil samples analyzed indicated the presence of VOCs above their respective regulatory screening levels during this subsurface investigation. Ethylbenzene and MTBE concentrations detected during the subsurface investigation in 2004 near the oil/water separators were not detected during this Phase II investigation. PCBs were not detected at soil boring B-11, located in the vicinity of the transformer, at concentrations above the laboratory method detection levels and/or its respective regulatory screening levels during this subsurface investigation. VOCs and TPH were not detected in any of the grab groundwater samples above analytical detection limits, except the fuel oxygenate MTBE. MTBE was detected in samples B-2-W and B-10-W; however, the reported MTBE concentrations were C:\Documents and Settings\lschan\Local Settings\Temporary Internet Files\Content.Outlook\A8FRGT6F\BRE Redwood City Phase II_vF (2).docx Page: 11/14

12 Mr. Dan Emerson August 12, 2010 below the corresponding ESL value. TPHd, detected during the subsurface investigation in 2004 near the former underground hydraulic hoists location, was not detected during this Phase II investigation. Confirmation of the presence/absence of the potential USTs cannot be confirmed without direct physical evidence. If a UST is exposed during construction, it should be removed in accordance with regulatory guidelines, and additional soil sampling is recommended to evaluate subsurface soil conditions at the UST locations. 8.0 LIMITATIONS The opinions and recommendations presented in this report are based upon the scope of services, information obtained through the performance of the services, and the schedule as agreed upon by ARCADIS and the party for whom this report was originally prepared.

26 : 8/4/2010 Client: Project: 640 Veterans Blvd Work Order: CASE RRATIVE Comments for method S_6010BCAM17, A MS/MSD, QC ID Note:The % recoveries for Barium, Beryllium, Chromium, Lead and Nickel are outside of laboratory control limits but are within % RPD limits. A post digestion spike was anlayzed and all elements were recovered within control limits indicating the poor MS/MSD recoveries are likely due to the heterogenity of the sample. The associated LCS/LCSD % recoveries and % RPD are within limits. No corrective action required. REVISIONS: Per client request, sample -003 removed from hold on 8/5/10 and analyzed for TPH as gasoline. Rev 1 (8/6/10) Page 2 of 109

123 DEFINITIONS: oratory s and Definitions Accuracy/Bias (% ) - The closeness of agreement between an observed value and an accepted reference value. Blank (/aration Blank) -MB/PB - An analyte-free matrix to which all reagents are added in the same volumes/proportions as used in sample processing. The method blank is used to document contamination resulting from the analytical process. Duplicate - a field sample and/or laboratory QC sample prepared in duplicate following all of the same processes and procedures used on the original sample (sample duplicate, LCSD, MSD) oratory Control Sample (LCS ad LCSD) - A known matrix spiked with compounds representative of the target analyte(s). This is used to document laboratory performance. Matrix - the component or substrate that contains the analyte of interest (e.g., - groundwater, sediment, soil, waste water, etc) Matrix Spike (MS/MSD) - Client sample spiked with identical concentrations of target analyte (s). The spiking occurs prior to the sample preparation and analysis. They are used to document the precision and bias of a method in a given sample matrix. Detection Limit () - the minimum concentration of a substance that can be measured and reported with a 99% confidence that the analyte concentration is greater than zero Practical Quantitation Limit () - a laboratory determined value at 2 to 5 times above the that can be reproduced in a manner that results in a 99% confidence level that the result is both accurate and precise. s reflect all preparation factors and/or dilution factors that have been applied to the sample during the preparation and/or analytical processes. Precision (%RPD) - The agreement among a set of replicate/duplicate measurements without regard to known value of the replicates Surrogate (S) or (Surr) - An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical process, but which is not normally found in environmental samples. Surrogates are used in most organic analysis to demonstrate matrix compatibility with the chosen method of analysis Tentatively Identified Compound (TIC) - A compound not contained within the analytical calibration standards but present in the GCMS library of defined compounds. When the library is searched for an unknown compound, it can frequently give a tentative identification to the compound based on retention time and primary and secondary ion match. TICs are reported as estimates and are candidates for further investigation. s: the unit of measure used to express the reported result - mg/l and (equivalent to PPM - parts per million in liquid and solid), ug/l and ug/kg (equivalent to PPB - parts per billion in liquid and solid), ug/m3, mg.m3, ppbv and ppmv (all units of measure for reporting concentrations in air), % ( equivalent to ppm or 1,000,000 ppb), ug/wipe ( concentration found on the surface of a single Wipe usually taken over a 100cm2 surface) LABORATORY QUALIFIERS: B - Indicates when the anlayte is found in the associated method or preparation blank D - Surrogate is not recoverable due to the necessary dilution of the sample E - Indicates the reportable value is outside of the calibration range of the instrument but within the linear range of the instrument (unless otherwise noted) Values reported with an E qualifier should be considered as estimated. H- Indicates that the recommended holding time for the analyte or compound has been exceeded J- Indicates a value between the method and and that the reported concentration should be considered as estimated rather the quantitative - Not N/A - Not Applicable NR - Not recoverable - a matrix spike concentration is not recoverable due to a concentration within the original sample that is greater than four times the spike concentration added R- The % RPD between a duplicate set of samples is outside of the absolute values established by laboratory control charts S- Spike recovery is outside of established method and/or laboratory control limits. Further explanation of the use of this qualifier should be included within a case narrative X -Used to indicate that a value based on pattern identification is within the pattern range but not typical of the pattern found in standards. Further explanation may or may not be provided within the sample footnote and/or the case narrative. Page 99 of 109

157 DEFINITIONS: oratory s and Definitions Accuracy/Bias (% ) - The closeness of agreement between an observed value and an accepted reference value. Blank (/aration Blank) -MB/PB - An analyte-free matrix to which all reagents are added in the same volumes/proportions as used in sample processing. The method blank is used to document contamination resulting from the analytical process. Duplicate - a field sample and/or laboratory QC sample prepared in duplicate following all of the same processes and procedures used on the original sample (sample duplicate, LCSD, MSD) oratory Control Sample (LCS ad LCSD) - A known matrix spiked with compounds representative of the target analyte(s). This is used to document laboratory performance. Matrix - the component or substrate that contains the analyte of interest (e.g., - groundwater, sediment, soil, waste water, etc) Matrix Spike (MS/MSD) - Client sample spiked with identical concentrations of target analyte (s). The spiking occurs prior to the sample preparation and analysis. They are used to document the precision and bias of a method in a given sample matrix. Detection Limit () - the minimum concentration of a substance that can be measured and reported with a 99% confidence that the analyte concentration is greater than zero Practical Quantitation Limit () - a laboratory determined value at 2 to 5 times above the that can be reproduced in a manner that results in a 99% confidence level that the result is both accurate and precise. s reflect all preparation factors and/or dilution factors that have been applied to the sample during the preparation and/or analytical processes. Precision (%RPD) - The agreement among a set of replicate/duplicate measurements without regard to known value of the replicates Surrogate (S) or (Surr) - An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical process, but which is not normally found in environmental samples. Surrogates are used in most organic analysis to demonstrate matrix compatibility with the chosen method of analysis Tentatively Identified Compound (TIC) - A compound not contained within the analytical calibration standards but present in the GCMS library of defined compounds. When the library is searched for an unknown compound, it can frequently give a tentative identification to the compound based on retention time and primary and secondary ion match. TICs are reported as estimates and are candidates for further investigation. s: the unit of measure used to express the reported result - mg/l and (equivalent to PPM - parts per million in liquid and solid), ug/l and ug/kg (equivalent to PPB - parts per billion in liquid and solid), ug/m3, mg.m3, ppbv and ppmv (all units of measure for reporting concentrations in air), % ( equivalent to ppm or 1,000,000 ppb), ug/wipe ( concentration found on the surface of a single Wipe usually taken over a 100cm2 surface) LABORATORY QUALIFIERS: B - Indicates when the anlayte is found in the associated method or preparation blank D - Surrogate is not recoverable due to the necessary dilution of the sample E - Indicates the reportable value is outside of the calibration range of the instrument but within the linear range of the instrument (unless otherwise noted) Values reported with an E qualifier should be considered as estimated. H- Indicates that the recommended holding time for the analyte or compound has been exceeded J- Indicates a value between the method and and that the reported concentration should be considered as estimated rather the quantitative - Not N/A - Not Applicable NR - Not recoverable - a matrix spike concentration is not recoverable due to a concentration within the original sample that is greater than four times the spike concentration added R- The % RPD between a duplicate set of samples is outside of the absolute values established by laboratory control charts S- Spike recovery is outside of established method and/or laboratory control limits. Further explanation of the use of this qualifier should be included within a case narrative X -Used to indicate that a value based on pattern identification is within the pattern range but not typical of the pattern found in standards. Further explanation may or may not be provided within the sample footnote and/or the case narrative. Total Page Count: 27 Page 24 of 27
