(Golder) is submitting the enclosed Water Quality Monitoring Report, which documents the results of the August 13 - 15, 2019, compliance monitoring event and the October 3, 2019, verification sampling event. The facility consists of an active municipal solid waste (MSW) landfill and a closed construction and demolition (C&D) landfill, each with a permitted monitoring network of wells and surface water locations. The MSW facility reverted back to detection monitoring from assessment monitoring before the first semi-annual 2018 water quality monitoring event after receiving approval from the North Carolina (NC) Department of Environmental Quality (DEQ) on February 2, 2018. In a follow-up correspondence dated June 5, 2018, statistically -derived, site -specific groundwater protection standards (GPS) were approved for thallium and vanadium. During this sampling event, no NC Appendix I organic or inorganic constituents were detected in samples from downgradient monitoring wells at the MSW landfill at quantifiable concentrations above groundwater standards. Two inorganic constituents (cobalt and vanadium) were detected at estimated concentrations above their respective groundwater standards in samples from one or more downgradient monitoring wells at the MSW landfill during the August 2019 sampling event. As presented, the detections of cobalt and vanadium are estimated (i.e., non -quantifiable) concentrations below the practical quantitation limit (PQL). Per 15A NCAC 02L .0202 (b)(1), no regulatory actions should be taken for estimated values below the PQLs that are above groundwater standards. In a correspondence sent to S&ME, Inc., dated September 12, 2008, the NC DEQ approved an alternate source demonstration (ASD) for thallium and vanadium as naturally occurring metals. Per 15A NCAC 02L .0202 (b)(3), concentrations of naturally occurring substances that exceed the NC 2L Groundwater Standards are exempt (i.e., not a violation of the standard). Further, site -specific groundwater protection standards (GPSs) were established for cobalt, thallium, and vanadium and the concentrations observed during the August 2019 sampling event were below their respective GPSs. In addition to the MSW landfill, Rowan County monitors groundwater at the closed C&D landfill for parameters listed in 15A NCAC 13B .0544 of the NCSWMR. One NC Appendix I organic constituent (benzene) was detected in samples collected from MW-18R and MW-19 at concentrations above the NC 2L Standard. Verification results from October 3, 2019 confirmed above -standard concentrations of benzene in samples collected from MW-18R and MW-19. As results are inconsistent with historical data, benzene concentrations will be verified during the next semi-annual sampling event to determine if further action (i.e., an assessment monitoring work plan) is warranted. Otherwise, field analytical data from the 2019 events are generally consistent with historical data. Two NC Appendix I inorganic constituents (cobalt and thallium) were detected in the samples from downgradient C&D monitoring wells at estimated concentrations above the groundwater standard but below the PQL. Cobalt was detected in samples from MW-18R and MW-19 and thallium was detected in samples from MW-18R at estimated concentrations above the groundwater standard but below the PQL. As presented, statistical analyses were previously used to establish a site -specific GPS for cobalt and thallium. The estimated concentrations of cobalt and thallium in samples from downgradient monitoring wells observed during the August 2019 sampling event are below the established site -specific GPS; therefore, no further action is necessary. J GOLDER October 2019 19123756.100 The indicator parameters iron and manganese were also detected in samples collected from MW-18R and MW-19 at quantifiable concentrations above their respective groundwater standards as they have been historically. The constituent 1,4-dioxane was detected at a concentration above the NC 2L Standard in the samples collected from MW-18R and MW-19 during this event; this constituent was analyzed per the May 30, 2018, memorandum and is not part of the facility permit -required testing at this time. Concentrations of detected NC Appendix I constituents were below applicable surface water standards during this sampling event with the exception of copper, which was detected at concentrations above the action level in samples collected from the upstream location SW-1 and downstream location SW-2. Because copper concentrations are similar upstream and downstream of the facility, they appear to be unrelated to facility operations and no further action is warranted. Constituent concentrations reported for the leachate samples collected during this sampling event are typical for Ieachate at this facility. Based on these results, Rowan County Environmental Services will continue monitoring the uppermost aquifer beneath this facility in accordance with the requirements of the Detection Monitoring Program as outlined in Title 15A NCAC 13B .1633 of the NCSWMRs for the MSW and the Detection Monitoring Program as outlined in Title 15A NCAC 13B .0544 of the NCSWMRs for the C&D facility. The next compliance monitoring event is tentatively scheduled for January 2020.

The Rowan County Landfill was permitted and is operated under the NC Solid Waste Permit (NCSWP) No. 80-03. The Rowan County Landfill consists of an active municipal solid waste (MSW) landfill, currently operated by Rowan County Environmental Services, and a closed construction and demolition (C&D) landfill. Rowan County (the County) has owned and operated the MSW and C&D landfills, which are co -located within the same property boundary, under permit No. 80-03 since 1989. The C&D landfill ceased accepting waste on June 30, 2008. The MSW landfill monitors water quality (i.e., groundwater, surface water, and leachate) semi-annually in accordance with Title 15A of the North Carolina Administrative Code (NCAC) Subchapter 13B .1633. The C&D landfill also monitors water quality (i.e., groundwater and surface water) semi-annually in accordance with 15A NCAC 13B .0544. 1.1 Site Description and Background The location of the facility is shown on the inlay on Drawing 1. As presented, the Rowan County solid waste facility is located approximately 1.5 miles southeast of the town of Woodleaf on Campbell Road in Rowan County, NC. The landfill facility covers approximately 355 acres of land and is bounded to the north by Campbell Road, to the south by Second Creek, and to the east and west by wooded, residential and agricultural properties. Surrounding land use is primarily rural residential, agricultural, or undeveloped and wooded. Access to the facility is via a driveway off of Campbell Road. As presented, the facility is comprised of an active Subtitle D MSW landfill unit and a closed C&D landfill unit (Drawing 1). Topographic elevations at the facility range from approximately 766 feet above mean sea level (AMSL) east of the existing scale house to approximately 635 feet AMSL at the edge of Second Creek along the southern property boundary. Stormwater drainage from the landfill and surrounding areas is directed by one of the two main drainage features toward Second Creek, which flows from the southwest to the northeast (S&ME October 2005). 1.2 Compliance Monitoring History Groundwater monitoring at the facility was initiated in December 1989 under the Detection Monitoring Program for MSW landfills. Currently, water quality monitoring is performed semi-annually at the MSW facility in accordance with the approved Water Quality Monitoring Plan (WQMP) and the NC Solid Waste Management Regulations (NCSWMR). The active MSW landfill monitoring network is currently comprised of 15 active monitoring wells (MW-1, MW-7, MW-9, MW-11, MW-12, MW-13, MW-16, MW-20, MW-23, MW-23A, MW-24R, MW-25, MW-26, MW-27, and MW-28R), which monitor the uppermost aquifer beneath the facility. Monitoring well MW-6, MW-27A, and MW-28 are monitored during each semi-annual sampling event for water levels only. Three monitoring wells (i.e., MW-17, MW-18R, and MW-19) monitor the C&D landfill located to the east of the active MSW landfill. Monitoring wells MW-3, MW-4, MW-5, MW-10, MW-18, MW-24, and MW-28 have been decommissioned. Following two consecutive assessment monitoring events without a detection of NC Appendix II constituents, the County requested to revert back to the Detection Monitoring Program, as governed by 15A NCAC 13B .1633 of the NCSWMR, following the completion of the July 2017 water quality monitoring event. NC DEQ approved the request in a correspondence dated February 2, 2018. The County was previously in Assessment Monitoring due ' GOLDER October 2019 19123756.100 to detections of tetrachloroethene and trichlorofluoromethane in samples from monitoring well MW-28. On July 11, 2017, MW-28R was installed as a replacement well for MW-28, as approved in a correspondence from NC DEQ dated December 13, 2016. Five surface water locations (SW-1 through SW-5) are also sampled during the semi-annual water quality monitoring events; SW-5 monitors surface water adjacent to the C&D landfill, the other four surface water locations monitor surface water surrounding the active MSW landfill; SW-1 is the upstream monitoring report. A French Drain is also sampled semi-annually to monitor a groundwater discharge point located underneath the Phase III landfill unit at the active MSW landfill. The locations of monitoring points within the current monitoring network are shown on Drawing 1. 1.3 Hydrogeologic Setting Geologically, the facility is located within the Charlotte Belt of the Piedmont Physiographic Province of NC (NCGS 1985). The Charlotte Belt is composed of Precambrian and Paleozoic bedrock, which is dominantly plutonic with plutons ranging from granite to gabbro. The oldest rocks in the Charlotte Belt are mafic gneisses, amphibolites, metagabbros and metavolcanic rocks, with lesser amounts of biotite gneiss, granitic gneiss, mica schist, quartzite and ultramafic rocks. Mica schists and mica hornblende gneisses locally have been intruded by granite. The rocks underlying the facility consist of mostly diorite, gabbro, and granite (NCGS 1985). The uppermost groundwater beneath the facility is present in a shallow, unconfined aquifer comprised of partially weathered, fractured, meta -volcanic rock. Groundwater occurs at depths ranging from near ground surface in valleys to more than 100 feet below grade on steep hills (S&ME October 2005). Depth -to -water measurements obtained during the August 2019 sampling event and summarized in Table 1 were used to prepare a groundwater surface contour map presented as on Drawing 1. As presented, groundwater in the uppermost aquifer beneath the facility generally flows to the southwest toward Second Creek. The groundwater surface contour map and interpreted flow directions are consistent with previously submitted groundwater surface contour maps for this facility. Based on the August 2019 groundwater surface contour map, the hydraulic gradient in the shallow aquifer underlying the facility averaged approximately 0.036. The average effective porosity of the shallow aquifer is estimated at 0.26 (S&ME October 2005). Using the above values, the estimated rate of groundwater flow for the uppermost aquifer beneath the facility was calculated using the following modified Darcy's Law equation: Ki Vyw n e where Vgw = average linear velocity (feet/year), K = hydraulic conductivity (feet/year), i = horizontal hydraulic gradient, and ne = effective porosity. As presented on Table 2, the average estimated linear groundwater flow velocity under the waste management units ranges from approximately 290 feet/year in the MSW area to approximately 520 feet/year in the C&D area, which is generally consistent with previous estimates. The linear velocity equation above makes the simplified assumptions of a homogeneous and isotropic aquifer. Therefore, this equation represents an estimated average value for the uppermost aquifer and does not account for heterogeneous and/or anisotropic conditions that are likely present in the uppermost aquifer at the facility. J GOLDER October 2019 19123756.100 2.0 FIELD PROGRAM, MONITORING RESULTS, AND DISCUSSION Field activities conducted as part of the August 2019 sampling event are discussed in the following sections. 2.1 Visual Inspection Program In order to determine if a potential release has occurred at the earliest possible time, the visual inspection program is used by sampling personnel at the Rowan County landfills. 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., leachate seeps), unexplained changes in soil characteristics, and any other change to the environment due to the waste management unit. During the August 2019 compliance monitoring event, no physical indicators were observed in the vicinity of the waste management areas. 2.2 Well Network and Groundwater Elevation Measurements As presented in Section 1.3 of this report, the current groundwater monitoring network at the Rowan County landfills (i.e., the active MSW and the closed C&D landfill) consists of 18 groundwater monitoring wells (i.e., 15 monitor groundwater at the MSW landfill and 3 monitor groundwater at the C&D landfill). Monitoring well construction information is summarized in Table 3 and the well locations are shown on Drawing 1. The network of monitoring wells was constructed to target the preferential flow path for groundwater underlying waste disposal areas. Water quality was monitored during the August 2019 water quality monitoring event (WQME) in accordance with the revised WQMP, which was approved by NC DEQ as part of the Phase IV expansion at the active MSW landfill in March 2013. Based on the WQMP monitoring wells MW-9 and MW-16 are the MSW landfill's background wells and are located hydraulically upgradient of the waste disposal area. Monitoring wells MW-1, MW-7, MW-11, MW-12, MW-13, MW-20, MW-23, MW-23A, MW-24R, MW-25, MW-26, MW-27, and MW-28R are located downgradient or side gradient of the waste disposal area and represent the facility's downgradient compliance wells. The C&D unit is monitored by upgradient well MW-17 and downgradient compliance wells MW-18R and MW-19. Depth -to -water measurements were recorded to the nearest 0.01 foot prior to initiating groundwater purging and sampling activities. The monitoring point summary and respective water level elevations for this event along with historical data are presented in Table 1. 2.3 August 2019 Groundwater and Surface Water Monitoring Event Personnel from Golder visited the facility on August 13 - 15, 2019, to purge and sample the 18 compliance groundwater monitoring wells. Samples were also collected for surface water monitoring locations and the facility's leachate pond. Surface water monitoring point SW-3 was dry during this event and no samples were obtained. Depth -to -water measurements were obtained from the network monitoring the wells to the nearest 0.01 foot using an electronic water level indicator prior to purging the wells. The groundwater monitoring wells were purged and sampled using dedicated bladder pumps and micro -purge procedures. Measurements of pH, specific conductivity, dissolved oxygen (DO), oxidation-reduction potential (ORP), temperature, turbidity, and depth -to -water were recorded each time the flow -cell volume was replaced depending on the purge rate. In general, the purge rate for each well was matched to the yield of the monitoring ' GOLDER October 2019 19123756.100 well, as determined by continuously monitoring the depth to water, up to a maximum purge rate of 300 milliliters per minute. Micro -purging was continued until stabilization was indicated by the field parameters. Prior to sampling, the laboratory -supplied sample containers used to collect the water samples detailed above 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 micro -purge groundwater samples were collected directly from the dedicated bladder pump discharge lines in the labeled, laboratory -supplied, pre -preserved sample containers after purging was completed based on stabilization of the field parameters. After collection, the sample containers were placed in a cooler on ice, under chain -of -custody control. Copies of the sampling logs detailing the sample ID, the personnel collecting the samples, the sampling location, the sampling equipment, the sampling method, general field observations, and field parameters are presented in Appendix A. Typically, the surface water samples and the French Drain groundwater samples are collected by lowering the sample containers directly into the surface water flow with the container opening facing away from the stream flow, taking care to prevent the overflow of the sample containers and to minimize sample induced turbidity. If necessary (i.e., if access to the sample point was limited) a stainless -steel dipper is lowered into the surface water flow and filled. The water sample collected in the dipper is then transferred directly to the provided appropriate sample containers. The leachate samples were collected directly from the leachate pond. Measurements of pH, conductivity, temperature, turbidity, DO, and ORP were recorded during the collection of the surface water samples directly from the point of sampling, and measurements of pH, specific conductivity, and temperature were recorded for the leachate sample from a separate sampling container. 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 sample ID, sampling personnel, sampling equipment, sampling location, sampling method, field observations, and water -quality measurements. 2.4 October 2019 Verification Event Golder personnel visited the facility on October 3, 2019, to verify the concentrations of benzene detected in samples collected from monitoring wells MW-18R and MW-19 during the August 2019 water quality monitoring event. Samples were collected utilizing techniques as described above. After collection, the samples were placed in a cooler on ice under chain -of -custody control. As presented, copies of the sampling logs are included in Appendix A. Included on the logs is a description of the sampling equipment, sampling method, field observations, location, and water quality measurements. 2.5 Laboratory Analysis Program The groundwater, surface water, and leachate samples collected on August 13 - 15, 2019, from the active MSW landfill were delivered by courier to Environmental Conservation Laboratories, Inc. (ENCO) of Cary, NC under chain -of -custody control for analysis of NC Appendix I constituents plus 1,4-dioxane. Groundwater samples collected on August 13 — 15, 2019 and October 3, 2019 from the closed C&D landfill were analyzed for the listed NC Appendix I constituents plus 1,4-dioxane, tetrahydrofuran, and the additional required C&D parameters required by NCAC 13B.0544. Surface water samples collected were analyzed for NC Appendix I plus 1,4-dioxane J GOLDER October 2019 19123756.100 per Solid Waste Section (SWS) policy requirements. The samples collected were received at the laboratory on August 16, 2019 and October 4, 2019 respectively, 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 August 2019 groundwater sampling event. In addition to the field blank, a laboratory -prepared trip blank accompanied the volatile organic compound (VOC) sample containers for the sampling event to and from the laboratory. ENCO analyzed the field blank for the same constituents as the groundwater samples, and the trip blank for NC Appendix I VOCs. A review of the laboratory data was performed by Golder personnel (included in Appendix 8). Barium and copper were detected at estimated concentrations in one more of the blanks. No other NC Appendix I organic or inorganic constituents were detected in the blank samples during this monitoring event. The following results are considered blank - qualified: copper at MW-20. No other data qualification was necessary. 4.0 DATA EVALUATION The results of the data evaluations are presented in the following sections. 4.1 North Carolina Groundwater and Surface Water Quality Standard Comparisons 4.1.1 MSW Facility Two inorganic constituents (cobalt and vanadium) were detected at estimated concentrations above their respective groundwater standards in samples collected from one or more downgradient and upgradient monitoring points at the MSW landfill during this event. As these are estimated (i.e., non -quantifiable) concentrations below the PQLs, per the 15A NCAC 02L .0202 (b)(1), no regulatory actions should be taken for estimated values below the PQLs that are above groundwater standards. In addition, a correspondence sent to S&ME on September 12, 2008 approved an ASD for thallium and vanadium as naturally occurring metals native to the site soils and groundwater. Per 15A NCAC 02L .0202 (b)(3), concentrations of naturally occurring substances that exceed the NC 2L Groundwater Standards are exempt (i.e., not a violation of the standard). At the request of NC DEQ in a February 2, 2018, letter, the GPS for thallium and vanadium was revised and approved subsequently approved in a correspondence dated June 5, 2018. Cobalt and vanadium concentrations are below previously approved and statistically -derived, site -specific groundwater protection standards (GPSs). 4.1.2 C&D Facility One NC Appendix I organic constituent (benzene) was detected in samples collected from MW-18R and MW-19 at concentrations above the NC 2L Standard. Verification samples collected from MW-18R and MW-19 on October 3, 2019 confirmed the above -standard concentrations of benzene at MW-18R and MW-19. As the results are inconsistent with historical data, benzene concentrations will be verified during the next semi-annual sampling event to determine if further action (i.e., an assessment monitoring work plan) is warranted. Otherwise, analytical results from the August 2019 water quality monitoring event is generally consistent with historical data. Two NC Appendix I inorganic constituent (cobalt and thallium) were detected in the samples collected from downgradient C&D monitoring wells at estimated concentrations above the groundwater standard but below the PQL. Cobalt was detected in samples from MW-18R and MW-19 and thallium was detected in samples from MW-18R at estimated concentrations above the groundwater standard but below the PQL. As the concentrations of cobalt and thallium are estimated (i.e., non -quantifiable) below the PQLs, per the 15A NCAC 02L .0202 (b)(1), ' GOLDER October 2019 19123756.100 no regulatory actions should be taken for estimated values below the PQLs that are above groundwater standards. Indicator parameters iron and manganese were also detected at MW-18R and MW-19 at quantifiable concentrations above their respective groundwater standards as they have been previously. The constituent 1,4- dioxane was detected at a concentration above the NC 2L Standard in the samples collected from MW-18R and MW-19 during this event; this constituent was analyzed per the May 30, 2018, memorandum and is not part of the facility permit -required testing at this time. 4.1.3 Surface Water Concentrations of detected Appendix I constituents were below applicable surface water standards during this sampling event except for copper, which was detected at concentrations above the action level at upstream location SW-1 and downstream location SW-2. Because copper concentrations are similar upstream and downstream of the facility, they appear to be unrelated to waste activities and no further action is warranted. 5.0 CONCLUSIONS Based on the results summarized herein, Rowan County Environmental Services will continue monitoring the uppermost aquifer beneath this facility in accordance with the requirements of the Detection Monitoring Program as outlined in Title 15A NCAC 13B .1633 at the MSW landfill and the Detection Monitoring Program as outlined in Title 15A NCAC 13B.0544 at the C&D landfill. The next compliance monitoring event is tentatively scheduled for January 2020. 6.0 REFERENCES Resolve (Resolve Environmental Services, P.A.), December 2004.

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 73 PROJECT NARRATIVE Date: 28 August 2019 Client: Golder Associates, Inc. (G0007) Project: Rowan County Active Landfills Lab ID: CC12924 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 Precision between duplicate spikes of 1,4-Dioxane exceeded acceptance criteria for the 8260D SIM ID MS and MSD samples. The QC batch was approved based on acceptable LCS recovery of this analyte. The 8260D LCS sample exhibited a high bias for 2-Butanone and the Continuing Calibration Verification sample (CCV) showed a high bias for 1,1,1-Trichloroethene, 1,2-Dichloroethene, 2-Butanone, 4-Methyl-2-pentanone, Acetone, Acrylonitrile, Bromodichloromethane, Carbon Tetrachloride, cis-1,3-Dichloropropene, Methylene chloride, trans- 1,4-Dichloro-2-buteneTrichlorofluoromethane, Vinyl acetate, and Vinyl chloride; however, these analytes were not detected in the associated samples, reducing the impact of the deviation. 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. Sample SW-3 was not submitted for analysis, as the source was dry at the time of collection. 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.

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. QL-02 The associated laboratory control sample exhibited high bias; since the result is ND, there is no impact. QM-10 LCS/LCSD were analyzed in place of MS/MSD. QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits.

DC 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. ➢ Field Blank: • Barium @ 2.69 ug/L (J) - none • Copper @ 2.38 ug/L (J), add B flags to the following: ■ MW-20 @ 2.11 ug/L (J) DC 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. ➢ Antimony and Thallium (2x) DC The report provides the reporting limit for each constituent. DC The results were reported at or below their proper reporting limits (i.e., MDLs with SWSLs reported). Those that are not reported correctly are listed below (by constituent) with the proper reporting limit listed beside them. State if the reporting limit error is due to dilutions. DC No organic or organic constituents were reported above their respective NC 2L Drinking Water Standards/GWPS in wells, or field/equipment/trip blanks, or above applicable surface water standards in surface water points. NC 2L/GWPS/MCL/IMAC Exceedances ➢ Cobalt (NC 2L IMAC = 1 ug/L) • MWA @ 2.18 ug/L (J) • MW-20 @ 6.41 ug/L (J) • MW-28R @ 3.54 ug/L (J) ➢ Vanadium (NC 2L IMAC = 0.3 ug/L) • MW-9 @ 2.56 ug/L (J) • MW-25 @ 7.26 ug/L (J) • MW-23A @ 5.07 ug/L (J) ➢ Copper (SW Standard 7 ug/L) • SWA (upstream) @ 22.9 ug/L • SW-2 @ 17.4 ug/L DC No inorganic or organic constituents were detected in a well or surface water point at quantified concentrations outside of their historical range (more than 5X previous GOLDER ASSOCIATES NC, INC.

Parameters Lab ID: CC12925 Overview 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 8260D Continuing Calibration Verification sample (CCV) exhibited a high bias for 1,1,1-Trichloroethane, 1,2-Dichloroethane, Chloroethane, and Trichlorofluoromethane; however, these analytes were not detected in the associated samples, reducing the impact of the deviation. LCS/LCSD were analyzed in place of the MS/MSD for the 8260D SIM analysis for 1,4-Dioxane. The spike recoveries of Alkalinity and Chloride were outside of control limits for the MS and MSD samples. The QC batches were approved based on acceptable LCS recovery of these analytes. Quality Control Remarks No Comments Other Comments The detections of Benzene in samples MW-18R and MW-19 were confirmed by reanalysis. The results of the reanalysis are available upon request. 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.

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-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.

DC Surrogate recoveries for each method are within the acceptable limits (i.e., at least 50% of the surrogates were within range). DC MS/MSD/LCS data results are provided for each analytical method. DC MS/MSD/LCS recoveries for each method are within the acceptable limits (i.e., at least 1 of the 3 were within range). ➢The 8260D Continuing Calibration Verification sample (CCV) showed a high bias for 1,1,1- Trichloroethene, 1,2-Dichloroethene, Chloroethane and Trichlorofluoromethane; however, these analytes were not detected in the associated samples, reducing the impact of the deviation. ➢ LCS/LCSD were analyzed in place of the MS/MSD for the 8260D SIM analysis for 1,4-Dioxane. ➢The spike recovery of Alkalinity and Chloride were outside of control limits for the MS and MSD samples. The QC batches were approved based on acceptable LCS recovery of these analytes. 4.0 ANALYTE LISTS/METHODS DC The proper number of constituents are present for each analyte list as identified above (including detects where applicable). DC Proper analytical methods were used for analysis. 5.0 DATA REPORTING DC All analytical reporting associated with the event was performed by the contracted lab. DC 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 INC.

I Page 13 Of 16 (� �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. QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there is no impact.

DC 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. DC 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. ➢ Antimony and Thallium (10x) DC The report provides the reporting limit for each constituent. DC The results were reported at or below their proper reporting limits (i.e., MDLs with SWSLs reported). Those that are not reported correctly are listed below (by constituent) with the proper reporting limit listed beside them. State if the reporting limit error is due to dilutions. DC No organic or organic constituents were reported above their respective NC 2L Drinking Water Standards/GWPS in wells, or field/equipment/trip blanks, or above applicable surface water standards in surface water points. DC No inorganic or organic constituents were detected in a well or surface water point at quantified concentrations outside of their historical range (more than 5X previous concentrations or first-time detections).
