(Golder) is submitting the enclosed Water Quality Monitoring Report, which documents the results of the August 25 - 27, 2021, compliance monitoring event and October 8, 2021, verification event. The facility consists of an active municipal solid waste (MSW) landfill and a closed construction and demolition debris (C&D) landfill, each with a permitted monitoring network of wells and surface water locations. The MSW facility reverted to detection monitoring for the first semi-annual 2018 water quality monitoring event after receiving approval from the North Carolina (NC) Department of Environmental Quality (DEQ) on June 5, 2018; in this same correspondence, statistically derived, site -specific groundwater protection standards (GPS) were approved for thallium and vanadium. Groundwater samples for the C&D landfill and the leachate sample were analyzed for 1,4-dioxane per the May 29, 2018, memorandum from the NC Department of Environmental Quality (DEQ). As approved by NC DEQ on January 4, 2021, wells MW-18R and MW-19 were replaced on May 13 - 14, 2021 with MW-18R2 and MW-19R, respectively, to locate the wells closer to the compliance boundary. At the MSW facility, two inorganic constituents (cobalt and vanadium) were detected at estimated concentrations above their respective groundwater standards [Interim Maximum Allowable Concentrations (IMACs)] in samples from one or more downgradient monitoring wells at the MSW landfill during this event. As these are estimated (i.e., non -quantifiable) concentrations below the method reporting limits, per 15A NCAC 02L .0202 (b)(1), no regulatory actions are required for estimated values below the reporting limits (a.k.a. Practical Quantitation Limits or PQLs) that are above groundwater standards. 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). Vanadium was detected at a quantifiable concentration above the groundwater standard from the French Drain sampling point during the August 2021 compliance event; however, the concentration was not confirmed during the October 2021 verification event as it was detected at an estimated concentration. In a September 12, 2008, correspondence from S&ME, Inc. the NC DEQ approved an alternate source demonstration (ASD) for naturally occurring thallium and vanadium. These exceedances were also previously reported in the November 30, 2018, ASD and 14-day notification, which provided evidence that cobalt and vanadium are naturally occurring. Alternate groundwater protection standards (GPS) for thallium and vanadium were approved by NC DEQ on June 5, 2018. Although some of the aforementioned detected concentrations are above their proposed site -specific GPS, as mentioned above, they are estimated below the PQL and no further action is warranted. Further, per NC Session Law 2021-153, references to IMACs are no longer applicable to solid waste facilities. 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 metal (thallium) was detected at an estimated concentration above the IMAC but below the PQL at MW-18R2 during this event. Also, the cobalt concentration at MW-18R2 was detected at a concentration above the PQL and was confirmed during verification sampling. Indicator parameters iron, manganese and total dissolved solids were also detected above their respective NC 2L Standards during this event: manganese at upgradient well MW-17 and downgradient wells MW-18R2 and MW-19R, andiron and total dissolved solids at MW-18R2. The concentrations of manganese, iron and total dissolved solids were confirmed in verification sampling of MW-18R2. k> GOLDER November 9, 2021 21456818.101 One Appendix I organic constituent (benzene) was detected in the sample from MW-18R2 at a concentration above the groundwater protection standard, which was confirmed during verification sampling. Also, 1,4-dioxane was also analyzed per the May 30, 2018, NC DEQ memorandum and detected at MW-18R2 and MW-19R at concentrations above the groundwater standard; this constituent is not part of the facility permit -required testing. NC Appendix I constituents were not detected during this event at concentration above the surface water standard. Constituent concentrations reported for the leachate samples collected during this sampling event are typical for leachate 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 for the MSW. Based on the confirmed benzene exceedance at MW-18R2 at the compliance boundary, the County will submit an Assessment Monitoring Work Plan February 7, 2022 for the closed C&D Landfill per Title 15A NCAC 13B. 0454.

An active municipal solid waste (MSW) landfill, operated by Rowan County Environmental Services, and a closed construction and demolition (C&D) landfill are located within the property boundary. Rowan County (the County) has owned and operated the MSW and C&D landfill under permit No. 80-03 since 1989. The C&D landfill located on site ceased accepting waste on June 30, 2008. The County monitors water quality (i.e., groundwater, surface water, and leachate) at the MSW landfill semi-annually in accordance with Title 15A of the North Carolina Administrative Code (NCAC) Subchapter 13B .1633. The County also monitors water quality (i.e., groundwater and surface water) at the C&D landfill semi- annually in accordance with 15A NCAC 13B .0544; the C&D facility closed in 2008. 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 375 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 discussed, the facility is comprised of an active Subtitle D MSW landfill unit, a closed C&D landfill unit, and a closed land clearing inert debris (LCID) 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. Wells MW-18R and MW-19 are scheduled to be replaced prior to the second semi-annual 2021 compliance monitoring event as approved by the NC DEQ on January 4, 2021. Monitoring wells MW-3, MW-4, MW-5, MW-10, MW-18, and MW-24 have been decommissioned. Following two consecutive Assessment Monitoring event without a detection of NC Appendix II VOCs, the County reverted to the Detection Monitoring Program during the August 2018 monitoring event as governed by 15A NCAC 13B .1633 of the NCSWMR, after receiving approval from the NC DEQ to revert to detection monitoring. The County was previously in Assessment Monitoring due 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 correspondence from NC DEQ dated December 13, 2016. After the Y aaL D!P November 9, 2021 21456818.101 completion of a second sampling event of MW-28R on November 1, 2017, a request was made to the NC DEQ to revert to detection monitoring after two consecutive monitoring events without the detection of volatile organic compounds (VOCs) in the replacement monitoring well MW-28R. The request to revert back to detection monitoring for the first semi-annual 2018 water quality monitoring event was approved by NC DEQ on June 5, 2018. On May 13 — 14, 2021, MW-18R2 and MW-19R were installed as replacement wells for MW-18R and MW- 19 closer to the compliance boundary as approved in correspondence with NC DEQ dated January 8, 2021. Five surface water locations (SW-1 through SW-5) are also sampled; 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 2021 sampling event and summarized in Table 1 were used to prepare a groundwater surface contour map presented as an overlay 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 2021 groundwater surface contour map, the hydraulic gradient in the shallow aquifer underlying the facility averaged approximately 0.035. 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 U9W 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 169 feet/year in the MSW area to approximately 509 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 4 aaL D5P November 9, 2021 21456818.101 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. 2.0 FIELD PROGRAM, MONITORING RESULTS, AND DISCUSSION Field activities conducted as part of the August 2021 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 in the vicinity of monitoring locations. During this compliance monitoring event, no physical indicators of a potential release were observed in the vicinity of the waste management areas by the sampling personnel. 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 17 groundwater monitoring wells (i.e., 14 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 2021 water quality monitoring event (WQME) in accordance with the revised WQMP, which was approved by NC DEQ as part of the Life of Site Permit Renewal in May 2021. 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-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-18R2 and MW-19R. 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 2021 Groundwater and Surface Water Monitoring Event Personnel from Golder visited the facility on August 25 - 27, 2021, to purge and sample the 17 compliance groundwater monitoring wells. Samples were also collected for surface water monitoring locations, French Drain and the facility's leachate pond. 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 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. Y aaL D!P November 9, 2021 21456818.101 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. The surface water samples, and the French drain groundwater samples were 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 2021 Verification Event Golder personnel visited the facility on October 8, 2021, to re -sample MW-18R2 and French Drain to verify the concentrations of vanadium at the French Drain and the concentrations of benzene, cobalt, manganese, iron, total dissolved solids atMW-18R2, which were detected in samples collected during the August 2021 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 2021, 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, the leachate sample was also analyzed for 1,4-dioxane. Groundwater samples collected from the closed C&D landfill were analyzed for the listed NC Appendix I constituents plus 1,4-dioxane, tetra hyd rofu ran, and the additional required C&D parameters under NCAC 13B.0544. Surface water samples were analyzed for NC Appendix 1, SW-5 is last analyzed for 1,4- dioxane. The samples were received at the laboratory on August 25, August 27 and August 30, 2021 in good condition and properly preserved. aaL 5P November 9, 2021 21456818.101 3.0 LABORATORY AND FIELD QA/QC A field blank was collected by Golder personnel as part of the August 2021 groundwater sampling event. In addition to the field blank, a laboratory -prepared trip blank accompanied the VOC sample containers for the sampling event to and from the laboratory. ENCO analyzed the field blank and method blanks 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 B). 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 [Interim Maximum Allowable Concentrations (IMACs)] in samples from one or more downgradient monitoring wells at the MSW landfill during this event. As these are estimated (i.e., non - quantifiable) concentrations below the method reporting limits, per 15A NCAC 02L .0202 (b)(1), no regulatory actions are required for estimated values below the reporting limits (a.k.a. PQLs) that are above groundwater standards. 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). Vanadium was detected at a quantifiable concentration above the groundwater standard from the French Drain sampling point during this event; however, metals concentrations are likely biased high by entrained sediment as evidenced by elevated field turbidity. This concentration was estimated below the PQL during the verification event and no further action is warranted. In a September 12, 2008, correspondence from S&ME, Inc. the NC DEQ approved an alternate source demonstration (ASD) for naturally occurring thallium and vanadium. These exceedances were also previously reported in the November 30, 2018, ASD and 14-day notification, which provided evidence that cobalt and vanadium are naturally occurring. Alternate groundwater protection standards for thallium and vanadium were approved by NC DEQ on June 5, 2018. Although some of the aforementioned detected concentrations are above their proposed site -specific GPS, as mentioned above, they are estimated below the PQL and no further action is warranted. Further, per NC Session Law 2021-153, references to IMACs are no longer applicable to solid waste facilities. 4.1.2 C&D Facility One NC Appendix I metal (thallium) was detected at an estimated concentration above the IMAC standard but below their respective PQLs at MW-18R2 during this event. Cobalt was detected at a quantifiable concentration above IMAC at MW-18R2. Verification samples from MW-18R2 on October 8, 2021 confirmed the above -standard concentrations of cobalt at MW-18R2. Indicator parameters iron, manganese and total dissolved solids (TDS) were also detected above their respective NC 2L Standards during this event (manganese at upgradient well MW-17 and downgradient wells MW-18R2 and MW-19; iron and TDS at MW-18R2). Verification samples from MW-18R2 on October 8, 2021 confirmed the above -standard concentrations of iron, manganese and total dissolved solids at MW-18R2 Y aaL D!P November 9, 2021 21456818.101 One NC Appendix I organic constituent (benzene) was detected in the sample from MW-18R2 at a concentration above the groundwater protection standard. Verification samples collected from MW-18R2 on October 8, 2021 confirmed the above -standard concentrations of benzene at MW-18R2. Also, 1,4-dioxane was analyzed per the May 30, 2018, memorandum and concentrations at MW-18R2 and MW-19R are above the groundwater standard and generally consistent with recent concentrations; this constituent is not part of the facility permit -required testing. 4.1.3 Surface Water NC Appendix I inorganic or organic constituents were not detected in the surface water sampling locations above the surface water standard during this sampling event. 5.0 CONCLUSIONS 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 for the MSW. Based on the confirmed exceedance of benzene at the compliance boundary at MW-18R2, the County will submit an Assessment Monitoring Work Plan by February 7, 2022 for the closed C&D Landfill per Title 15A NCAC 13B. 0454.

GROUNDWATER CONTOURS ARE BASED ON LINEAR INTERPOLATION BETWEEN AND EXTRAPOLATION FROM KNOWN DATA, TOPOGRAPHIC CONTOURS, AND KNOWN FIELD CONDITIONS. THEREFORE, GROUNDWATER CONTOURS MAY NOT REFLECT ACTUAL GROUNDWATER CONDITIONS. 5. GROUNDWATER CONTOUR LINES SHOW THE WATER TABLE SHAPE AND ELEVATION. THESE CONTOURS ARE INFERRED LINES FOLLOWING THE GROUNDWATER SURFACE AT A CONSTANT ELEVATION ABOVE SEA LEVEL. THE GROUNDWATER FLOW DIRECTION IS GENERALLY PERPENDICULAR TO THE GROUNDWATER SURFACE CONTOURS, SIMILAR TO THE RELATIONSHIP BETWEEN SURFACE WATER FLOW AND TOPOGRAPHIC CONTOURS. 6.

(G0007) Project: Rowan County Active Landfills Lab ID: CE11488 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 8260D LCS exhibited a low bias for 1,2-Dichloropropane and Vinyl chloride; however these analytes were detected in the CRL standard, verifying instrument sensitivity. The spike recovery for Toluene was outside control limits for the MS sample. The QC batch was approved based on acceptable LCS recovery of this analyte. Quality Control Remarks No Comments Other Comments All samples received under this work order arrived in acceptable conditions. The samples were not checked for 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.

I Page 60 Of 66 (� �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. A-07 Analyte biased low in LCS but detected in the reporting limit standard. Since the analyte in the associated sample was not detected, there is no impact on data quality. QL-02 The associated laboratory control sample exhibited high bias; since the result is ND, there is no impact. 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.

Any particular difficulties encountered during sample handling by ENCO are discussed in the QC Remarks section below. Quality Control Samples The 8260D LCS exhibited a high bias for Toluene; however, this analyte was not detected in the associated samples. The Continuing Calibration Verification (CCV) exhibited a high bias for 2-Hexanone, Chloroethane, and trans- 1,4-Dichloro-2-butene; however, these analytes were not detected in the associated samples. The spike recoveries for Chlorobenzene and Toluene were outside control limits for the MS and/or MSD samples; however, these analytes were not detected in the associated samples. The spike recovery for Alkalinity was outside control limits for the MS and MSD samples. The QC batch was approved based on acceptable LCS recovery of this analyte. Quality Control Remarks No Comments Other Comments All samples received under this work order arrived in acceptable conditions. The samples were not checked for chlorine, as it is not required.

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-07 The spike recovery was outside acceptance limits for the MS and/or MSD.

(G0007) Project: Rowan County Landfill Leachate Lab ID: CE11484 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 8260D Continuing Calibration Verification (CCV) exhibited a high bias for 2-Hexanone, Chloroethane, and trans- 1,4-Dichloro-2-butene; however, these analytes were not detected in the associated samples. The spike recovery for Phosphorus was outside control limits for the MSD sample. The QC batch was approved based on acceptable LCS recovery of this analyte. Quality Control Remarks No Comments Other Comments Sample 8003-L1 for 8260D was processed at a dilution due to matrix interference, resulting in elevated reporting limits All samples received under this work order arrived in acceptable conditions. The samples were not checked for 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. QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there is no impact. R-04 The Reporting Limits for this analysis are elevated due to sample foaming. FINAL This report relates only to the sample as received by the laboratory, and may only be reproduced in full.

GOLDER ASSOCIATES NC, INC. QUALITY ASSURANCE & QUALITY CONTROL G O L D E R LABORATORY DATA REVIEW MEMBER OF WSP Page 3 of 3 *> 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. ➢ All VOCs including, Antimony, Thallium (10x); 1,4-dioxane (20x) 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). DC Other report issues/Communications with laboratory/etc.: ➢ Sample 8003-L1 for 8260D was processed at a dilution due to matrix interference, resulting in elevated reporting limits. 2�SQ pCCgF ENCO Laboratories 9e0 Accurate.

I Page 7 Of 1 O (� �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.
