GOLDER April 22, 2019 19116638.101 Executive Summary Golder Associates NC, Inc. (Golder) is submitting the enclosed Water Quality Monitoring Report, which documents the results of the January 30 - 31, 2019, semi-annual compliance monitoring event at the Waste Industries of High Point Construction and Demolition Landfill. One North Carolina (NC) Appendix I inorganic constituent (cobalt at MW-6) was detected at quantifiable concentration above the applicable groundwater standard during the January 2019 event. Cobalt, vanadium, and thallium were detected at one or more wells at estimated concentrations below the practical quantitation limits (PQLs) but above applicable groundwater standards during this event. As the concentrations are below their respective PQLs, no further action is warranted. Indicator parameters iron, manganese, and total dissolved solids (TDS) were detected at quantifiable concentrations above their respective NC 2L Standards in samples from one or more downgradient wells during this event, as they have been during previous events. As presented in previous reports and alternate source demonstrations (ASDs), based on published soil and stream sediment metals data for Guilford County and North Carolina, the barium, cobalt, vanadium, iron, and manganese concentrations reported in the groundwater samples were visually compared to and are generally within natural background concentrations. One NC Appendix I organic compound, benzene, was detected above the NC 2L Standard in samples from groundwater monitoring wells MW-2 and MW-6 during the January 2019 event. Additionally, 1,4-dioxane was detected in the samples from MW-2, MW-3, MW-5, MW-6, MW-8, AMW-1, and AMW-2 at quantifiable concentrations above the groundwater protection standard; this constituent was analyzed per the May 30, 2018, NC Department of Environmental Quality (DEQ) memorandum and is not part of the facility permit -required testing. No NC Appendix I inorganic or organic constituents were detected at concentrations that exceeded applicable surface water standards during the January 2019 event. 1,4-Dioxane was reported above the applicable surface water standard in upstream monitoring point SW-3 and downstream surface water monitoring points SW-2 and SW-4. Because 1,4-dioxane was detected in the upstream monitoring point at a similar concentration, it appears that the source in surface water is not the landfill unit, and no further action is warranted. Based on these results, the facility will continue groundwater monitoring in accordance with the requirements of the Assessment Monitoring Program as outlined in Title 15A NCAC 13B .0545. Waste Industries proposes to install an additional background monitoring well facilitate meaningful statistical comparisons to some of the downgradient wells and further evaluate concentrations of inorganic constituents. The next event is tentatively scheduled for July 2019.

The active C&D Landfill is owned and operated by Waste Industries under Permit No. 41-16 issued by the NC Department of Environmental Quality (DEQ). 1.1 Site Description and Background The location of the facility is shown on the inlay on Figure 1. As presented, the Waste Industries of High Point C&D Landfill is located along Riverdale Road within the city limits of Jamestown in Guilford County, NC. The site consists of approximately 154 acres, of which, approximately 17.2 acres is currently permitted as the Phase 1 and Phase 2 waste units. There are three small unnamed streams that traverse the site and flow into an unnamed tributary of Richland Creek, which forms the southern property boundary as shown on Figure 1. The first unnamed tributary is a southwest trending stream that forms the northwestern property boundary. The second tributary is a southwest trending drainage in the center of the property and lies just east of the Phase 2 waste unit. The third tributary is a southwest trending drainage in the eastern portion of the site. A large man-made pond is located near the eastern property boundary. A small storm water basin was constructed in the northwest corner of the facility and a larger storm water basin was constructed along the southwestern part of the site during the construction of Phase 1. Topographic surface elevations at the facility range from approximately 700 to 820 feet above mean sea level. The western portion of the site mainly consisted of trees and heavy brush before Phase 1 of the C&D landfill was constructed. Now, most of that area consists of landfill operations. The eastern portion of the site has historically been used for agricultural purposes. A reclamation facility is located at the northernmost part of the site. A large portion of the surrounding properties are agricultural, sparse residential, or owned by the City of High Point for operations associated with Kersey Valley Landfill. 1.2 Compliance Monitoring History Groundwater monitoring at the facility was initiated in October 2003 after approval of the Groundwater Monitoring Plan by the NC DEQ. Currently the facility's monitoring network is comprised of eight monitoring wells (MW-1, MW-2, MW-3, MW-4S, MW-5, MW-6, MW-7S, and MW-8), which monitor the uppermost aquifer beneath the facility. Monitoring wells MW-7S and MW-8 were installed in July 2006 to monitor the Phase 2 expansion at the facility. Two assessment monitoring wells, AMW-1 and AMW-2, were installed in December 2016. In addition to the groundwater monitoring points, the facility's monitoring network includes four surface water sampling points, SW-1 and SW-3, which are upstream from the waste area, and SW-2 and SW-4, which are downstream monitoring points. These points are sampled in conjunction with the groundwater monitoring wells in accordance with the facility's permit. Vinyl chloride and benzene were detected in the sample from downgradient monitoring well MW-2 at concentrations above their respective reporting limits and NC 2L Standards during the July 2014 sampling event. On February 3, 2015, an Alternate Source Demonstration was submitted in response to this detection that provided evidence that an unidentified source other than the waste unit is likely responsible for the volatile organic GOLDER April 22, 2019 19116638.101 compounds (VOCs) detected in the samples from MW-2. On March 2, 2015, NC DEQ issued a response letter that allowed an additional six months to assess potential sources of VOCs. Benzene was detected in the sample from MW-2 at a concentration above the SWSL and NC 2L Standard during the August 2015 sampling event and the facility transitioned to an Assessment Monitoring Program. An Assessment Monitoring Notification and Work Plan (Work Plan) was submitted to the NC DEQ on December 7, 2015, and was approved on January 28, 2016. The approved Work Plan stated that samples from groundwater monitoring wells MW-1 and MW-2 would be analyzed for the NC Appendix II list of constituents during the first semi-annual water quality monitoring event of 2016 and during subsequent events, MW-1 and MW-2 would be analyzed for NC Appendix I list of constituents plus detected NC Appendix II constituents. No additional NC Appendix II constituents were detected in the samples from MW-1 and MW-2 during the February 2016 event and therefore, future events will be analyzed for the NC Appendix I list of constituents. Benzene was detected in the sample from MW-6 at a concentration above the SWSL and NC 2L Standard during the July 2016 sampling event. Based on the July 2016 monitoring results, an Assessment Monitoring Notification and Work Plan Addendum (Addendum) was submitted to the NC DEQ on October 21, 2016, and was approved on October 31, 2016. The approved Addendum stated that assessment monitoring wells, AMW-1 and AMW-2, would be installed downgradient of MW-2 and MW-6, respectively. The Addendum also stated that samples from groundwater monitoring wells MW-6, AMW-1, and AMW-2 would be analyzed for the NC Appendix II list of constituents during the first semi-annual water quality monitoring event of 2017 and during subsequent events, MW-6, AMW-1, and AMW-2 would be analyzed for NC Appendix I list of constituents plus detected NC Appendix II constituents. Assessment monitoring wells AMW-1 and AMW-2 were installed in December 2016 in accordance with the Addendum and sampled for the first time during the January 2017 event. As part of ongoing remedial efforts, Waste Industries completed final soil cap construction for Phases 1 and 2 in July 2017. Additionally, 14 in waste passive landfill gas vents were installed, some of which are located in proximity to areas of known VOC groundwater contamination at groundwater monitoring wells MW-2, MW-6, and MW-8. Based on average horizontal groundwater flow rates for the facility which are relatively low, it could take more than 25 years for groundwater located below the landfill gas vents to travel to the impacted groundwater monitoring wells. Waste industries is continuing to evaluate the effects of the recently installed soil cap and landfill gas vents on groundwater quality along the western waste boundary at MW-2, MW-6, and MW-8 prior to evaluating any additional remedies. 1.3 Hydrogeologic Setting Geologically, the facility is located within the Carolina Slate Belt of the Piedmont Physiographic Province of North Carolina (NCGS, 1985). Generally, the Carolina Slate Belt consists of Late Proterozoic to Cambrian volcanic and greenschist-facies metasedimentary rocks intruded by plutonic suites (Butler and Secor, 1991). The site geology is characterized by a regional -scale felsic intrusive complex, which consists mainly of white to gray, fine- to coarse -grained, massive to foliated metamorphosed granitic rock. The region is characterized by regional and small scale Mesozoic diabase dikes. The uppermost groundwater beneath the facility is present in a shallow, unconfined aquifer comprised of saprolite, partially weathered rock (PWR), and granitic bedrock. Groundwater occurs at depths of approximately 25 feet below grade along the northern upgradient side of the waste disposal area, and at a depth of less than 10 feet below grade along the perimeter downgradient boundary. Depth to water measurements, obtained during the GOLDER April 22, 2019 19116638.101 January 2019 monitoring event and summarized in Table 1, were used to prepare a groundwater surface contour map presented on Figure 1. Surface water and groundwater at the site generally flows south to southwest towards a tributary of Richland Creek. Richland Creek is approximately 1300 feet south of the site and flows to the Deep River, which is approximately 0.5 miles from the site. Groundwater beneath the site flows in three distinguishable and vertically interconnected hydrogeologic units; saprolite, PWR, and bedrock. The groundwater surface contour map and interpreted flow directions are consistent with previously submitted interpretations for this facility. Based on the January 30, 2019, groundwater contour map, the average hydraulic gradient in the shallow aquifer underlying the site, as measured along the conceptual flow path shown on the contour map, was calculated to be approximately 0.042 feet per foot (Table 2). Groundwater velocities were calculated using a hydraulic conductivity of 1.37E-05, which is the geometric mean of the hydraulic conductivities for each of the hydrogeologic units present at the facility. The estimated effective porosity of the shallow aquifer is expected to range from 0.20 (saprolite) to 0.09 (fractured rock). The effective porosity of the fractured rock was used in calculations to provide a conservative estimate of groundwater flow. Using the above values, the estimated rate of groundwater flow for the uppermost aquifer beneath the facility was calculated using the following modified Darcy equation: V9w = KI/ne where V9w = average linear velocity (feet/year), K = hydraulic conductivity (feet/year), i = horizontal hydraulic gradient, and ne = effective porosity. The average estimated linear groundwater flow velocity under the waste management unit is approximately 6.5 feet/year, which is generally consistent with previous estimates (Table 2). The range of groundwater flow is expected to vary depending on the hydrogeologic unit in which it occurs. The linear velocity equation above makes the simplified assumptions of a homogeneous and isotropic aquifer. Therefore, this equation represents a likely average value for the uppermost aquifer and does not account for heterogeneous and/or anisotropic conditions that may be present in the uppermost aquifer at the facility. 2.0 FIELD PROGRAM, MONITORING RESULTS AND DISCUSSION Field activities conducted for the January 2019 sampling event are discussed in the following sections. 2.1 Visual Inspection Program In order to ensure that a potential release is detected at the earliest possible time, the visual inspection program is used by Golder personnel at the Waste Industries of High Point C&D Landfill. This program includes physical indicators such as potential water table mounding beneath the waste management unit, physical examination of any stresses in biological communities, visible signs of leachate migration (i.e., Ieachate seeps), unexplained changes in soil characteristics, and any other change to the environment due to the waste management unit. During the January 2019 compliance monitoring event no physical indicators of a potential release were observed in the vicinity of the waste management areas. 2.2 Well Network and Groundwater Elevation Measurements The current approved network of groundwater monitoring wells at the facility consists of eight compliance monitoring wells and two assessment monitoring wells. Monitoring well construction information is summarized 4 GOLDER April 22, 2019 19116638.101 on Table 3 and the well locations are shown on Figure 1. The well locations were selected to yield groundwater samples representative of the conditions in the uppermost aquifer underlying the facility, and to monitor for potential releases from the landfill unit. Two upstream (SW-1 and SW-3) and two downstream (SW-2 and SW-4) surface water monitoring points are also monitored and are shown on Figure 1. Monitoring well MW-1 is the facility's background well and is located hydraulically upgradient of the waste disposal area. Monitoring wells MW-2, MW-3, MW-4S, MW-5, MW-6, MW-7S, MW-8, AMW-1, and AMW-2, are located downgradient of the waste disposal area and represent the facility's downgradient wells. The well locations were selected to yield groundwater samples representative of the conditions in the uppermost aquifer underlying the facility and monitor for potential releases from the landfill unit. Depth -to -water measurements were recorded to the nearest 0.01 foot prior to initiating groundwater purging and sampling activities. The respective groundwater level elevations for this event are presented in Table 1 along with historical water level data. As presented, the data indicate that the hydraulic head level in the uppermost aquifer beneath the facility is fairly consistent, with temporal variation from the long-term average limited to approximately 5 feet (plus or minus). As expected, the range in fluctuation appears to be greater in the upgradient well MW-1, as this well is located in a groundwater recharge area. The range in fluctuation in downgradient compliance wells, which are located near groundwater discharge areas, is much less, presumably due to the stabilizing effect of the hydraulic discharge boundary. 2.3 January 2019 Groundwater and Surface Water Monitoring Event Personnel from Golder visited the facility on January 30 - 31, 2019, to purge and sample monitoring wells MW-1, MW-2, MW-3, MW-4S, MW-5, MW-6, MW-7S, MW-8, AMW-1, and AMW-2, and to sample surface water monitoring points SW-1, SW-2, SW-3, and SW-4. Depth -to -water measurements were obtained from the network monitoring wells and additional wells (MW-4D and MW-7D) to the nearest 0.01 foot using an electronic water level indicator prior to purging the wells. Compliance monitoring wells were purged and sampled using low -flow sampling techniques from dedicated bladder pumps. Assessment monitoring wells were purged and sampled using low -flow sampling techniques from portable bladder or peristaltic pumps. Measurements of temperature, pH, specific conductivity, dissolved oxygen (DO), oxidation-reduction potential (ORP), and turbidity were recorded on approximately 3- to 5-minute intervals during the purge, depending on the purge rate. In general, the purge rate was matched to the yield of the monitoring well, as determined by continuously monitoring the depth -to -water, not allowing the purge rate to exceed 350 milliliters per minute. Purging was continued until stabilization was indicated by the field parameters. Prior to sampling, the laboratory -supplied sample containers were prepared. Each sample container was labeled with the sample identification number, sampling personnel, date and time of sample collection, project name and number, and requested chemical analyses. The required groundwater samples were collected directly from the dedicated bladder pump discharge lines into the labeled, laboratory -supplied, pre -preserved sample containers after purging was completed based on stabilization of field parameters. The surface water samples were collected directly from the stream flow, by lowering the sample containers into the stream flow with the opening facing away from the current flow, taking care to prevent the over flow of the sample containers and to minimize sample -induced turbidity. Measurements of temperature, pH, specific conductivity, DO, ORP, and turbidity were recorded during the collection of the surface water samples. 4 GOLDER April 22, 2019 19116638.101 After collection, the samples were placed in a cooler on ice, under chain -of -custody control. Copies of the sampling logs are presented in Appendix A. Included in each log is a description of the sampling equipment, sampling location, sampling method, field observations, and field measurements. 1_4 Laboratory Analysis Program The January 2019 groundwater and surface water samples were shipped to Environmental Conservation Laboratories, Inc. (ENCO) of Cary, NC under chain -of -custody control for analysis. As presented, the January 2019 groundwater samples from MW-1, MW-2, MW-3, MW-4S, MW-5, MW-6, MW-7S, MW-8, AMW-1, and AMW-2 were analyzed for the NC Appendix I list of constituents plus the C&D indicator parameters specific to 15A NCAC 13B .544(a)(1)(D). The surface water samples at the facility were analyzed for the NC Appendix I list of constituents. Groundwater and surface water samples were also analyzed for tetrahydrofuran, as required in a memo issued by NC DEQ dated June 25, 2010. Surface water and groundwater samples were analyzed for 1,4-dioxane per the May 29, 2018, memorandum from the NC DEQ. The samples were received at the laboratory on January 31, 2019, and February 1, 2019, in good condition and properly preserved. 3.0 LABORATORY AND FIELD QA/QC A field blank was collected by Golder personnel as part of the January 2019 sampling event. ENCO analyzed the field blank for the NC Appendix I list of constituents plus iron; manganese; mercury; 1,4-dioxane; and tetrahydrofuran. In addition to the field blank, a laboratory -prepared trip blank accompanied the volatile sample containers to and from the laboratory and was analyzed for NC Appendix I VOCs plus 1,4-dioxane and tetrahydrofuran. ENCO analyzed the laboratory blanks for the same parameters analyzed for the groundwater samples. A review of the laboratory data was performed by Golder personnel and is included in Appendix B. Tetrahydrofuran was detected at quantifiable concentrations in one or more of the lab blanks during the January 2019 event. Based on data reviews performed by Golder, no data qualification was necessary. 4.0 DATA EVALUATION 4.1 North Carolina Groundwater and Surface Water Quality Standard Comparisons Analytical results and field parameters for the January 2019 groundwater samples are summarized in Tables 4 and 5 along with available historical data. As presented in Table 4, one NC Appendix I inorganic constituent (cobalt at MW-6) was detected at a quantifiable concentration above the practical quantitation limit (PQL) and groundwater standard during the January 2019 event. Cobalt was also detected at estimated concentrations below the PQL, but above the groundwater standard, in the samples from MW-2, MW-8, AMW-1, and AMW-2. Vanadium was detected at estimated concentrations below the PQL, but above the groundwater standard in the samples from upgradient well MW-1 and downgradient wells MW-4S and MW-7S. Thallium was detected at estimated concentrations below the PQL, but above the groundwater standard in samples from upgradient well MW-1 and downgradient wells MW-2, MW-3, MW-4S, MW-7S, AMW-1, and AMW-2. As the concentrations are estimated (i.e., non -quantifiable) concentrations below the method reporting limits, per the 15A NCAC 02L .0202 (b)(1), no regulatory actions should be taken for estimated values below the reporting limits (a.k.a. PQLs) that are above groundwater standards. The indicator parameters iron, manganese, and total dissolved solids (TDS) were detected at quantifiable concentrations above their respective NC 2L Standards in samples from one or more downgradient wells during this event. One NC Appendix I VOC, benzene, was detected at quantifiable concentrations above the NC 2L 4 GOLDER April 22, 2019 19116638.101 Standard in the samples from MW-2 and MW-6 during the January 2019 event. Additionally, 1,4-dioxane was detected in the samples from MW-2, MW-3, MW-5, MW-6, MW-8, AMW-1, and AMW-2 at quantifiable concentrations above the groundwater protection standard; this constituent was analyzed per the May 30, 2018, NC Department of Environmental Quality (DEQ) memorandum and is not part of the facility permit -required testing. Analytical results and field parameters for the January 2019 surface water samples are summarized in Tables 6 and 7 along with available historical data. No NC Appendix I constituents were reported at concentrations above applicable surface water standards during the event. 1,4-Dioxane was reported above the applicable surface water standard in upstream monitoring point SW-3 and downstream surface water monitoring points SW-2 and SW-4. Because 1,4-dioxane was detected in the upstream monitoring point at a similar concentration, it appears that the source in surface water is not the landfill unit, and no further action is warranted. 5.0 CONCLUSIONS As part of ongoing remedial efforts, Waste Industries completed final soil cap construction for Phases 1 and 2 in July 2017. Additionally, 14 in waste passive landfill gas vents were installed, some of which are located in proximity to areas of known VOC groundwater contamination at groundwater monitoring wells MW-2 and MW-6. Based on average groundwater flow rates presented in Section 1.3 and Table 2, it could take more than 25 years for groundwater located below the landfill gas vents to travel to the impacted groundwater monitoring wells. Waste Industries continues to evaluate the effects of the recently installed soil cap and landfill gas vents on groundwater quality along the western waste boundary at MW-2 and MW-6 prior to evaluating additional remedies. Waste Industries proposes to install an additional background monitoring well (MW-9) facilitate meaningful statistical comparisons to some of the downgradient wells and further evaluate concentrations of inorganic constituents. The proposed location is shown on Figure 1. The facility will continue monitoring in accordance with the requirements of the Assessment Monitoring Program as outlined in Title 15A NCAC 13B.0545, the Work Plan, and Addendum. The next groundwater monitoring event is tentatively scheduled for July 2019. 6.0 REFERENCES Butler, J. Robert and Secor, Donald T., Jr., 1991, The Central Piedmont, in Horton, J.

(G0007) Project: WI of High Point LF, LLC Lab ID: CCO0957 Overview (� �Eo www.encolabs.com Environmental Conservation Laboratories, Inc. (ENCO) analyzed all submitted samples in accordance with the methods referenced in the laboratory report. Any particular difficulties encountered during sample handling by ENCO are discussed in the QC Remarks section below. Quality Control Samples For the 8260D SIM analysis for 1,4-Dioxane, LCS/LCSD were analyzed in place of the MS/MSD. Tetrahydrofuran was detected in the 8260D Method Blank. Detections of this analyte should be considered to have a possible high bias if the concentration in the associated sample is not greater than ten times that of the detection in the Method Blank. The reported concentration of Tetrahydrofuran is within historical range for this sampling point. The spike recovery of Trichloroethene was outside of control limits for the 8260D MS sample. The QC batch was approved based on acceptable LCS recovery of this analyte. The spike recoveries of Iron and Manganese were outside of control limits for the 6010D MSD and Post Spike samples. The QC batch was approved based on acceptable LCS recovery of these elements. The spike recoveries of Chloride and Sulfate were outside of control limits for the MS sample. The QC batch was approved based on acceptable LCS recovery of these analytes. Quality Control Remarks No Comments Other Comments All samples received under this work order arrived in acceptable conditions. The samples were not checked for residual chlorine, as it is not required. The analytical data presented in this report are consistent with the methods as referenced in the analytical report. Any exceptions or deviations are noted in the QC remarks section of this narrative or in the Flags/Notes and Definitions section of the report.

J The reported value is between the laboratory method detection limit (MDL) and the laboratory method reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable. U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. E The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is based on the low point of the calibration curve, when applicable, sample preparation factor, dilution factor, and, in the case of soil samples, moisture content. PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL. N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater confidence) to make a "tentative identification". P Greater than 25% concentration difference was observed between the primary and secondary GC column. The lower concentration is reported. QB-02 The method blank contains analyte at a concentration above the MDL, but since it was not detected in the sample, there is no impact on data quality. QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable LCS recovery. QM-08 Post -digestion spike did not meet method requirements due to confirmed matrix effects (dilution test). QM-10 LCS/LCSD were analyzed in place of MS/MSD.

(G0007) Project: WI of High Point, LLC Lab ID: CC00958, CCO1648 Overview (� �Eo www.encolabs.com Environmental Conservation Laboratories, Inc. (ENCO) analyzed all submitted samples in accordance with the methods referenced in the laboratory report. Any particular difficulties encountered during sample handling by ENCO are discussed in the QC Remarks section below. Quality Control Samples Tetrahydrofuran was detected in the 8260B Method Blank; however, this analyte was not detected in the associated samples, reducing the impact of the deviation. For the 8260D analysis for 1,4-Dixoane, LCS/LCSD were analyzed in place of the MS/MSD. The spike recoveries of Iron and Manganese were outside of control limits for the 6010D MSD and Post Spike samples. The QC batch was approved based on acceptable LCS recovery of these elements. The spike recoveries of Alkalinity, Chloride, and Sulfate were outside of control limits for the MS and/or MSD samples. The QC batches were approved based on acceptable LCS recovery of these analytes. Quality Control Remarks No Comments Other Comments All samples received under this work order arrived in acceptable conditions.

I Page 60 Of 67 (� �Eo www.encolabs.com FLAGS/NOTES AND DEFINITIONS B The analyte was detected in the associated method blank. D The sample was analyzed at dilution. J The reported value is between the laboratory method detection limit (MDL) and the laboratory method reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable. U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. E The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is based on the low point of the calibration curve, when applicable, sample preparation factor, dilution factor, and, in the case of soil samples, moisture content. PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL. N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater confidence) to make a "tentative identification". P Greater than 25% concentration difference was observed between the primary and secondary GC column. The lower concentration is reported. 0-01 This compound is a common laboratory contaminant. QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable LCS recovery. QM-08 Post -digestion spike did not meet method requirements due to confirmed matrix effects (dilution test). QM-10 LCS/LCSD were analyzed in place of MS/MSD. QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there is no impact.

EV Proper EPA SM 2540C-1997 analytical methods were used for analysis. 5.0 DATA REPORTING EV All analytical reporting associated with the event was performed by the contracted lab. EV Trip, field and/or equipment, and laboratory blank results have all been reported. All detects for blanks are listed below by constituent. All laboratory method blanks, if any, have been 'flagged' with a 'B' where detected in other samples as appropriate and a laboratory narrative was provided. If the sample was flagged by the laboratory and is not within 5X of the concentration in the blank (or 1 OX for commonly detected laboratory contaminants -acetone, methylene chloride and phthalates), list below with explanation if flags should be removed. If flags need to be added for samples, also list below. GOLDER ASSOCIATES NC, INC. QUALITY ASSURANCE & QUALITY CONTROL G O L D E R LABORATORY DATA REVIEW Page 4of5 IL No data qualification needed based on blank detections EV It is clear from the laboratory report that samples have or have not been diluted during analysis, and if the samples have been diluted, the result is reported as a multiple of the dilution (e.g., a sample diluted 10x resulting in an analytical detection of 1.0 should be reported as 10). Those that have been diluted are listed below with the dilution factor. ➢AII wells and SW points, Antimony and Thallium- 2x ➢1,4-Dioxane — AMW-2 and MW-6 (5x) ➢Total Alkalinity as CaCO3 — MW-1 (2x), MW-2 (10x), AMW-2 (5x), MW-6 (10x), MW-8 (5x) ➢Sulfate as SO4 — MW-1 and MW-6 (3x) ➢MW-6 Chloride — MW-6 (3x) and MW-8 (2x) EV The report provides the reporting limit for each constituent.
