' GOLDER November 8, 2019 19116638.102 Executive Summary Golder Associates NC, Inc. is submitting the enclosed Water Quality Monitoring Report, which documents the results of the July 10 - 11, 2019, semi-annual compliance monitoring event and the October 4, 2019, verification sampling event at the Waste Industries of High Point Construction and Demolition Landfill. Two NC Appendix I inorganic constituents were detected at quantifiable concentrations above the applicable groundwater standards and practical quantitation limits (PQLs) in samples from one or more groundwater monitoring wells during the July 2019 event. Barium was detected at quantifiable concentrations above the NC 2L Standard in samples from MW-2 and MW-6 during the event. Cobalt was detected at quantifiable concentrations above the NC 2L Interim Maximum Allowable Concentration (IMAC) in samples from MW-2, MW-6, and AMW-2 during the event. Additional background inorganic concentration data are being collected during the semi-annual events from piezometer P-3 to evaluate the recent detections in samples from downgradient wells in accordance with the Assessment Monitoring Work Plan Addendum 2, dated November 8, 2019. The July 2019 event was the first background sampling event for P-3. Cobalt, vanadium, and thallium were detected in samples from one or more wells at estimated concentrations below the 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. Benzene was detected above the NC 2L Standard in samples from groundwater monitoring wells MW-2, MW-6, and AMW-2 during the July 2019 event. Verification sampling was performed for benzene at AMW-2 on October 4, 2019; the benzene concentration was confirmed. No other NC Appendix I organic constituents were detected in samples from groundwater wells above applicable water quality standards. Additionally, 1,4-dioxane was detected in the samples from MW-2, MW-5, MW-6, MW-8, AMW-1, and AMW-2 at quantifiable concentrations above the groundwater protection standard. Constituent 1,4-dioxane 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 July 2019 event. The constituent 1,4-dioxane was reported above the applicable surface water standard in upstream monitoring point SW-3 and downstream surface water monitoring point SW-4. Because 1,4-dioxane was detected in the upstream monitoring point at a similar concentration, it appears that the 1,4-dioxane source in surface water is not the landfill unit, and no further action is warranted. 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 volatile organic compound groundwater contamination at groundwater monitoring wells MW-2 and MW-6. Due to the relatively low horizontal groundwater flow rates for the facility, 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. J GOLDER November 8, 2019 19116638.102 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. During the July 2019 event, Waste Industries sampled piezometer P-3, which is located upgradient of the waste unit, to collect additional inorganic constituent data to further evaluate concentrations of inorganic constituents recently detected in samples from downgradient wells. The next event is tentatively scheduled for January 2020.

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 November 8, 2019 19116638.102 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. Additional background inorganic concentration data are being collected during the semi-annual events from piezometer P-3 to evaluate the recent detections in samples from downgradient wells in accordance with the Assessment Monitoring Work Plan Addendum 2, dated November X, 2019. The July 2019 event was the first background sampling event for P-3. 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. Due to the relatively low horizontal groundwater flow rates for the facility, 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 J GOLDER November 8, 2019 19116638.102 below grade along the perimeter downgradient boundary. Depth to water measurements, obtained during the July 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 July 10, 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: VgW = KI/ne where VgW = 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 6.6 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 July 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 July 2019 compliance monitoring event no physical indicators of a potential release were observed in the vicinity of the waste management areas. ' GOLDER November 8, 2019 19116638.102 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. One piezometer, which is located hydraulically upgradient of the waste disposal area, is being monitored to collect additional background metals data. Monitoring well construction information is summarized 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. Piezometer P-3 is located hydraulically upgradient of the waste disposal area and is being monitored to collect additional background metals data. 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 July 2019 Groundwater and Surface Water Monitoring Event Personnel from Golder visited the facility on July 10 - 11, 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, AMW-2, and piezometer P-3 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. Surface water monitoring point SW-2 was dry during the event and was unable to be sampled. 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, 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 ' GOLDER November 8, 2019 19116638.102 number, and requested chemical analyses. The required groundwater samples were collected directly from the 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. 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. 2.4 October 2019 Verification Groundwater Monitoring Event Golder personnel visited the facility on October 4, 2019, to re -sample AMW-2 to verify the benzene concentration detected during the July 2019 event. The well was purged and sampled utilizing the same techniques as those described above. After collection, the sample was placed in a cooler on ice, under chain -of -custody control for analysis. A copy of the sampling log is presented in Appendix A. Included in the log is a description of the sampling equipment, sampling method, field observations, location, and water quality measurements 2.5 Laboratory Analysis Program The July 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 July 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). Piezometer P-3 was analyzed for the NC Appendix I metals plus iron, manganese, and mercury. 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 July 11, 2019, and July 12, 2019, in good condition and properly preserved. The October 4, 2019, sample from AMW-2 was shipped to ENCO under chain -of -custody control for analysis to be analyzed for benzene. The sample was received at the laboratory on October 8, 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 July 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. Barium, copper, manganese, and methylene chloride were reported at estimated concentrations in the field blank and based on Golder's review of the laboratory data the follow detections are considered blank - qualified: Copper in samples from MW-1, MW-2, MW-4S, MW-8, AMW-1, P-3, SW-1, SW-3, and SW-4; manganese in samples from MW-1, MW-3, and MW-7S; and methylene chloride in the sample from MW-8. ' GOLDER November 8, 2019 19116638.102 4.0 DATA EVALUATION 4.1 North Carolina Groundwater and Surface Water Quality Standard Comparisons Analytical results and field parameters for the July 2019 groundwater samples are summarized in Tables 4 and 5 along with available historical data. As presented in Table 4, two NC Appendix I inorganic constituents were detected at quantifiable concentrations above the applicable groundwater standards and practical quantitation limits (PQLs) in samples from one or more groundwater monitoring wells during the July 2019 event. Barium was detected at quantifiable concentrations above the NC 2L Standard in samples from MW-2 and MW-6 during the event. Cobalt was detected at quantifiable concentrations above the NC 2L Interim Maximum Allowable Concentration (IMAC) in samples from MW-2, MW-6, and AMW-2 during the event. Additional background inorganic concentration data is being collected during the semi-annual events from piezometer P-3 to evaluate the recent concentrations in samples from downgradient wells. The July 2019 event was the first background sampling event for P-3 Cobalt was also detected at estimated concentrations below the PQLs, but above the IMAC, in samples from MW-8 and AMW-1. Thallium was detected at estimated concentrations below the PQLs, but above the IMAC, in samples from upgradient well MW-1 and assessment well AMW-2. Vanadium was detected at estimated concentrations below the PQLs, but above the IMAC, in samples from MW-6 and MW-7S during this event. 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. Indicator parameter iron was detected at quantifiable concentrations above its NC 2L Standard in samples from upgradient piezometer P-3 and downgradient wells MW-2, MW-4S, MW-5, MW-6, MW-8, AMW-1, and AMW-2. Indicator parameter manganese was detected at quantifiable concentrations above its NC 2L Standard in samples from MW-2, MW-4S, MW-5, MW-6, MW-8, AMW-1, and AMW-2. Indicator parameter total dissolved solids (TDS) was detected at quantifiable concentrations above its NC 2L Standard in samples from MW-2, MW-6, MW-8, and AMW-2. 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. Benzene was detected above the NC 2L Standard in samples from groundwater monitoring wells MW-2, MW-6, and AMW-2 during the July 2019 event. The concentration at AMW-2 was confirmed during a verification sampling event performed on October 4, 2019. No other NC Appendix I organic constituents were detected in samples from groundwater wells above applicable water quality standards. Additionally, 1,4-dioxane was detected in the samples from MW-2, MW-5, MW-6, MW-8, AMW-1, and AMW-2 at quantifiable concentrations above the NC 2L Standard. Constituent 1,4-dioxane was analyzed per the May 30, 2018, NC Department of Environmental Quality (DEQ) memorandum and is not part of the facility permit -required testing. As stated in Section 1.2, a final soil cap was completed for Phases 1 and 2 and 14 gas vents were installed into the landfill in July 2017. Due to the relatively low flow rates downgradient of the landfill, the effects of these improvements on water quality are still being evaluated. Analytical results and field parameters for the July 2019 surface water samples are summarized in Tables 6 and 7 along with available historical data. No NC Appendix I inorganic or organic constituents were detected at ' GOLDER November 8, 2019 19116638.102 concentrations that exceeded applicable surface water standards during the July 2019 event. The constituent 1,4-dioxane was reported above the applicable surface water standard in upstream monitoring point SW-3 and downstream monitoring point 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 During the July 2019 event, Waste Industries sampled piezometer P-3, which is located upgradient of the waste unit, to collect additional inorganic constituent data to further evaluate concentrations of inorganic constituents recently detected in samples from downgradient wells. 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 January 2020. 6.0 REFERENCES Butler, J. Robert and Secor, Donald T., Jr., 1991, The Central Piedmont, in Horton, J.

Unless otherwise noted in an attached project narrative, all samples were received in acceptable condition and processed in accordance with the referenced methods/procedures. Results for these procedures apply only to the samples as submitted. The analytical results contained in this report are in compliance with NELAC standards, except as noted in the project narrative if applicable. This report shall not be reproduced except in full, without the written approval of the Laboratory. This report contains only those analyses performed by Environmental Conservation Laboratories. Unless otherwise noted, all analyses were performed at ENCO Cary. Data from outside organizations will be reported under separate cover. If you have any questions or require further information, please do not hesitate to contact me. Sincerely, Stephanie Franz Project Manager Enclosure(s) FINAL This report relates only to the sample as received by the laboratory, and may only be reproduced in full. I Page 1 of iJJ PROJECT NARRATIVE Date: 25 July 2019 Client: Golder Associates, Inc. (G0007) Project: WI of High Point, LLC Lab ID: CC11262, CC11861 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 The spike recovery of 1,4-Dioxane was outside of control limits for the 8260D MS and MSD samples due to high concentrations of analyte in the source sample. The batch was approved based on acceptable LCS recovery of this analyte. LCS/LCSD were analyzed in place of the MS/MSD for some of the submitted samples. The spike recoveries of Iron, Manganese, and Mercury were outside of control limits for the 601 OD (7470 for Mercury) MS, MSD, and/or Post Spike samples. The QC batches were approved based on acceptable LCS recovery of these elements. The spike recovery of Chloride was outside of control limits for the MS sample. The QC batch was approved based on acceptable LCS recovery of this analyte. Quality Control Remarks The surrogate spike recovery of Toluene-d8 exceeded acceptance criteria for the 8260D SIM analysis for 1,4-Dioxane for the Trip Blank. 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. Sample SW-2 was not submitted for analysis, as the source was dry at the time of analysis. 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.

I Page 58 Of 65 (� �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. [CALC] Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses. 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. QM-17 Matrix spike recovery was outside acceptance limits due to high concentrations of analyte in source sample.

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. [CALC] Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses. 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).
