(Golder) is submitting this Water Quality Monitoring Report, which documents the results of the compliance monitoring and corrective action monitoring results from the March 15 - 16, 2021 groundwater and surface water sampling and analysis event and the June 15, 2021 verification sampling event at the closed Henderson County closed municipal solid waste (MSW) and construction and demolition (C&D) Landfill. At the closed MSW facility, no North Carolina (NC) Appendix I inorganic constituents were reported at quantifiable concentrations that exceed groundwater protection standards in samples from downgradient monitoring wells. Cobalt and thallium were detected at estimated concentrations above their respective groundwater standards [i.e., NC 2L Interim Maximum Allowable Concentrations (IMACs)] in the samples from one or more downgradient monitoring wells. Per 15A NCAC 02L .0202 (b)(1), "where the standard (i.e., the NC 2L Standard) for a substance is less than the practical quantitation limit (PQL), the detection of that substance at or above the PQL constitutes a violation of the standard." For cobalt, the groundwater standard is 1 microgram per liter (ug/L) and the PQL is 10 ug/L. For thallium, the groundwater standard is 0.2 ug/L and the PQL is 2 ug/L. As presented, the cobalt and thallium concentrations are below their respective PQLs and are considered estimated; therefore, no further action is warranted. A desktop study using the United State Geological Survey National Geochemical Survey Database researched the prevalence of cobalt and thallium in soil and sediment in the general proximity of the Henderson County MSW Landfill was presented in the First Semi -Annual 2019 Water Quality and Corrective Action Monitoring Report dated July 15, 2019. The study shows that cobalt and thallium occur naturally in stream sediment and is likely to occur in subsurface soil at the Henderson County MSW Landfill at concentrations that would account for the concentrations of these constituents in groundwater. Therefore, the estimated exceedances likely originate from natural soils and rock. At the MSW facility, two NC Appendix I volatile organic constituents (VOCs), benzene and 1,4-dichlorobenzene, were detected at quantifiable concentrations that exceeded their respective NC 2L Standards in the samples from MW-7 at the MSW landfill during the March 2021 event. 1,4-dioxane was detected at quantifiable concentrations above the NC 2L Standard in the samples from MW-7 and AMW-1 D at the MSW landfill during the March 2021 event. 1,4-dioxane was analyzed per the May 29, 2018, memorandum from the NC Department of Environmental Quality (DEQ) and is not part of the approved monitoring plan. At the C&D facility, No NC Appendix I inorganic constituents were reported at concentrations that exceed the PQLs and groundwater protection standards in the samples from downgradient monitoring wells. Cobalt was detected at estimated concentrations above the IMAC in samples from MW-11 and MW-12. As described above, no further action is recommended for these estimated concentrations. Indicator parameter iron was reported at quantifiable concentrations above the NC 2L Standard in samples from downgradient monitoring wells MW-11 and MW-13. The indicator parameter manganese was reported at quantifiable concentrations above the NC 2L Standard in samples from downgradient monitoring wells MW-11, MW-12, and MW-13. Total Dissolved Solids was reported at a quantifiable concentration above the NC 2L Standard in the samples from MW-11 and MW-12 and sulfate was detected at a quantifiable concentration above the NC 2L Standard in the sample from MW-11. The concentrations of these indicator parameters are similar to historical results for the C&D facility monitoring wells. Jaa�!R June 25, 2021 20147157.102 The USGS National Geochemical Survey Database indicates that concentrations of cobalt, iron, and manganese in stream sediment samples within 25 miles of the facility likely contribute to the concentrations detected in groundwater samples from the C&D monitoring wells. Therefore, the aforementioned exceedances likely originate from natural soils and rock. At the C&D facility, vinyl chloride was detected at concentrations that exceeded the PQL and groundwater protection standard at downgradient monitoring well MW-13. Vinyl chloride was also detected at MW-12 at an estimated concentration above the groundwater protection standard. Constituent 1,4-dioxane was detected at a quantifiable concentration above the NC 2L Standard in the sample from MW-12. On September 28, 2010, the County submitted an Alternate Source Demonstration (ASD) to NC DEQ in response to VOC concentrations detected in samples from the closed C&D landfill downgradient monitoring wells. Based on the data and evaluations from the ASD, it was apparent that leachate from the C&D disposal unit is not the likely source of the VOC concentrations; data suggest that the source of the VOCs in samples from the monitoring wells is likely landfill gas. Concentrations of vinyl chloride samples from MW-12 and MW-13 have shown a declining trend for the last 7 years. Lead was detected at quantifiable concentrations above applicable surface water standards in the samples from surface water monitoring points BR-1 and SW-1 during the March 2021 event. Lead was also detected at estimated concentrations above applicable surface water standards in the samples from surface water monitoring points BR-2 and BR-3 during the March 2021 event. The surface water was relatively turbid at each of the sampling locations during the event and entrained sediment was likely biasing the lead concentrations high. Each surface water location was resampled for analysis of lead during a verification event on June 15, 2021. Lead was not detected above the method detection limit in any of the samples, which is consistent with historical data. No NC Appendix I VOCs were detected at concentrations above the applicable surface water standards. 1,4-dioxane was detected at a quantifiable concentration above the applicable surface water standard in the sample from BR-2, as it has been historically. Based on these results, the County will continue the implementation of groundwater corrective action at the MSW landfill for the unconsolidated aquifer in accordance with the approved Corrective Action Plan. Also based on the results, the County will continue monitoring the C&D landfill in accordance with the requirements of the Assessment Monitoring Program as outlined in Title 15A NCAC 13B.0545. The next compliance monitoring event for this facility is scheduled for September 2021.

R °V v June 25, 2021 1.0 INTRODUCTION 20147157.102 This report summarizes the monitoring results from the March 15 - 16, 2021, groundwater and surface water sampling and analysis event and the June 15, 2021 verification sampling event at the closed Henderson County Landfill in Henderson County, North Carolina in accordance with Title 15A of the North Carolina Administrative Code (NCAC) Subchapter 1313.1632 and NCAC Subchapter 1313.0544. The Henderson County Landfill, which consists of a closed municipal solid waste (MSW) and a closed construction and demolition (C&D) landfill, is maintained by the County under Permit No. 45-01 issued by the NC Department of Environment Quality (DEQ, formerly Department of Environment and Natural Resources). 1.1 Site Description and Background The location of the facility is shown on the inlay on Figure 1. As presented, the closed Henderson County Landfill is located approximately three miles northwest of the city of Hendersonville, off Stoney Mountain Road. The County maintains an approximately 120-acre landfill facility that consists of a closed, unlined C&D over MSW facility; a closed, unlined C&D facility; a closed, unlined facility formerly operated by the Tennessee Valley Authority (TVA); an active transfer station, and a customer convenience center. A white goods area, a yard waste disposal area, and a beneficial reuse area are also present on the property. Unpermitted waste was discovered along the eastern portion of the southern property boundary in 2011, during the construction of a road to the customer convenience center. The waste, which appears to consist of mainly C&D material, extends off -site to an adjacent parcel. The MSW facility is subject to Assessment Monitoring in accordance with .1634 of the Solid Waste Management Rules (SWMR) and the Transition Plan for the facility. The C&D facility is subject to water quality monitoring in accordance with the January 1, 2007, revision to the C&D Rules (.0544 of the SWMR) and is currently in Assessment Monitoring. Water quality monitoring is also required for the adjacent Tennessee Valley Authority (TVA) landfill. The facility has been in operation since the 1940s, beginning with the TVA landfill. In January 1998, the MSW facility ceased accepting MSW waste and began placing C&D waste over the MSW waste. After closure of the C&D-over-MSW area, a new C&D landfill began operation on the southeastern portion of the facility property. The C&D-over-MSW area was capped with a modified clay cap. The County ceased accepting waste at the stand-alone C&D landfill on June 30, 2008 and completed closure activities on June 30, 2009. The landfill is bounded to the north and east by residential and undeveloped wooded properties, to the south by Stoney Mountain Road and residential and wooded properties, and to the west by a tributary of Mill Pond Creek, a NC Department of Transportation maintenance yard, and a Henderson County School bus maintenance facility. Topographic relief at the landfill ranges from approximately 2170 to 2590 feet above mean sea level. Surface drainage from the facility is predominantly to the southwest toward several streams along the western and southern portions of the property. These features drain into Mill Pond Creek located southwest of the landfill. 1.2 Compliance Monitoring History The following sections summarize the compliance monitoring histories of the closed MSW landfill, the closed C&D landfill, and the closed TVA landfill. 1.2.1 Closed MSW Landfill Henderson County monitors water quality at the closed MSW landfill by sampling one upgradient background monitoring well (MW-5), and three downgradient monitoring wells (MW-6, MW-7, and MW-8) semi-annually. Samples from the wells have historically been analyzed for the NC Appendix II list for the first semi-annual event and the NC Appendix I list plus mercury during the second semi-annual event. Two assessment Jaa�!R June 25, 2021 20147157.102 monitoring wells (AMW-1 S and AMW-1 D) have also been monitored semi-annually since April 2002. Samples from the assessment wells have historically been analyzed for the NC Appendix I list plus mercury during each semi-annual event. Based on the documented exceedances of applicable groundwater standards for volatile organic compounds (VOCs), the County submitted an Additional Groundwater Assessment Proposed Work Plan to NC DEQ on September 26, 2008. NC DEQ approved the Work Plan on April 17, 2008, and the County submitted the Assessment Report on June 3, 2008. As part of the Assessment Report, assessment monitoring wells AMW-2S and AMW-2D were installed to further delineate the VOC plume. As part of this submittal, Camp Dresser & McKee (CDM) recommended that AMW-2S and AMW-2D continue to be sampled semi-annually. On September 17, 2009, representatives of the County and Golder met with NC DEQ and submitted a Groundwater Assessment Work Plan to NC DEQ to address continued assessment activities at the MSW and C&D facilities. During the meeting, it was verbally agreed that TVA well MW-9 would no longer be sampled and would remain for water level collection, and wells AMW-1 S, AMW-1 D, AMW-2S, and AMW-2D would be sampled for NC Appendix I constituents plus mercury. Follow-up emails were received on September 18, 2009, regarding approval to discontinue monitoring MW-9, and on February 2, 2010, regarding approval of reduced analytical parameters for the four assessment monitoring wells. In a letter to the County dated May 12, 2011, NC DEQ requested that MW-9 be sampled on an annual basis for NC Appendix I constituents to monitor the closed TVA landfill; currently the well is sampled during the first semi-annual compliance events of each year. Four downstream surface water monitoring points, BR-1, BR-2, BR-3, and SW-1, have been monitored semi-annually for NC Appendix I parameters. In July 2012, Henderson County submitted a Nature and Extent Study (NES) to the NC DEQ with the purpose of delineating the vertical and horizontal extent of those constituents identified in the groundwater samples at concentrations that exceed their respective groundwater standards. The NC DEQ granted approval of the NES on October 18, 2012. The October 18, 2012, approval letter of the NES required the County to initiate an Assessment of Corrective Measures (ACM) per the NCAC 15A NCAC 13B.1635 of the NC Solid Waste Management Rules. An ACM was submitted to the NC DEQ on April 15, 2013. The ACM was approved by NC DEQ on May 22, 2013, and the County held a public hearing to discuss the ACM and potential remedies for the site on August 15, 2013. A Corrective Action Plan (CAP) was submitted to the NC DEQ on June 24, 2015 and was approved on July 13, 2015. As specified in the CAP, monitored natural attenuation (MNA) was implemented as the corrective action along with a super aerated water (SAW) pilot test in the southwestern portion of the facility. A Corrective Action Evaluation Report (CAER) for the SAW pilot test was submitted to the NC DEQ on October 25, 2019. The 2019 CAER proposed that methylene chloride be removed as a constituent of concern (COC) and that SAW injections cease unless VOCs are detected above the NC 2L Standard in samples from groundwater monitoring wells screened in the partially weathered rock / fractured bedrock aquifer. The 2019 CAER was approved by the NC DEQ on November 5, 2019. A CAER for the MNA program was submitted to the NC DEQ on September 4, 2020. The 2020 CAER proposed that tetrachloroethene and trichloroethene be removed as COCs. The 2020 CAER was approved by the NC DEQ on September 9, 2020. 1.2.2 Closed C&D Landfill The County monitors water quality at the C&D facility by sampling one upgradient monitoring well (MW-10), and three downgradient monitoring wells (MW-11, MW-12, and MW-13) semi-annually. Samples from the wells have been analyzed for the NC Appendix I list plus mercury and indicator parameters. On September GOLoDER 4 June 25, 2021 20147157.102 28, 2010, the County submitted an Alternate Source Demonstration (ASD) to NC DEQ in response to VOC concentrations detected in samples from the closed C&D landfill downgradient monitoring wells. Based on the data and evaluations from the ASD, it was apparent that leachate from the C&D disposal unit is not the likely source of the VOC concentrations. Additionally, the data suggest that the source of the VOCs in samples from the monitoring wells is likely landfill gas. On May 12, 2011, NC DEQ issued a letter to the County to initiate an Assessment Monitoring Program at the C&D facility. The County submitted an Assessment Monitoring Work Plan to NC DEQ on September 21, 2011 and sampled the C&D landfill monitoring wells for the NC Appendix II list of constituents during the September 2011. Prior to the September 2012 compliance monitoring event, NC DEQ allowed the County to sample the C&D wells for the NC Appendix I list of constituents plus 2,4-D after conducting two baseline NC Appendix II sampling events 1.3 Hydrogeologic Setting Geologically, the facility is located within the Chauga Belt of the Blue Ridge Physiographic Province of NC (NCGS, 1985 and 2004). The Chauga Belt is comprised of Cambrian intrusive metamorphic rocks of monzonitic to granodioritic origin. The Chauga Belt is considered a low-grade metamorphic part of the Inner Piedmont Belt and is bordered to the west by the Brevard thrust fault zone. The facility is underlain primarily by the Henderson Gneiss which is a medium -gray, biotite granite augen composed of microcline, oligoclase, quartz, biotite, and minor amounts of muscovite, epidote, and titanite (Butler and Secor, 1991). The topography of the area is characterized by rolling, rounded hills with broad valleys and moderately steep ravines typically containing streams. The uppermost groundwater beneath the facility is present in a shallow, unconfined aquifer comprised of partially weathered, fractured, metamorphic intrusive rock. Topographic relief at the site ranges from an elevation of approximately 2590 feet above mean sea level (AMSL) along the eastern property boundary and slopes downward to the southwest to an approximate elevation of 2170 feet AMSL along the western property boundary. As a result of the varying topographic relief at the site, groundwater occurs at depths of ranging from approximately 6 to 55 feet below grade. Depth -to -water measurements obtained during the March 2021 monitoring event are summarized in Table 1 and were used to prepare a groundwater surface contour map presented as an overlay on Figure 1. As presented, the groundwater flow in the uppermost aquifer beneath the site is generally toward the southwest toward a tributary of Mill Pond Creek, which is located along the western property boundary of the site. The groundwater contour map and interpreted flow directions are generally consistent with previously submitted groundwater contour maps and flow directions. Based on the March 2021 groundwater surface contour map, the average hydraulic gradient in the shallow aquifer underlying the MSW landfill was calculated to be approximately 0.09 foot/foot (Table 2). The hydraulic gradient underlying the C&D landfill was calculated to be approximately 0.28 foot/foot (Table 2). A hydraulic conductivity of 1.26E-04 centimeters/second is used based on an average of previous hydraulic conductivities calculated for specific wells (CDM, October 2008). An estimated effective porosity of 0.15 was used for the shallow aquifer to represent a range from saprolite to fractured rock (CDM, December 2008). 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. Jaa�!R June 25, 2021 20147157.102 The average estimated linear groundwater flow velocity under the MSW landfill is approximately 74 feet/year, which is generally consistent with previous estimates (Table 2). The average estimated linear groundwater flow velocity under the C&D landfill is approximately 247 feet/year (Table 2). The range of groundwater flow is expected to vary depending on the hydrogeologic unit in which it occurs. However, 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 March 2021 and June 2021 sampling events are discussed in the following sections. 2.1 Visual Inspection Program To detect a potential release at the earliest possible time, the visual inspection program is used by sampling personnel at the closed Henderson County 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., leachate seeps), unexplained changes in soil characteristics, and any other change to the environment due to the waste management unit. During the compliance monitoring event, no physical indicators of a potential release were observed in the vicinity of the waste management area. 2.2 Well Network and Groundwater Elevation Measurements The following sections summarize the water quality networks and groundwater elevation measurements for the closed MSW landfill, the closed C&D landfill, and the closed TVA landfill. 2.2.1 Closed MSW Landfill The network of groundwater monitoring wells at the closed Henderson County MSW landfill consists of one upgradient monitoring well (MW-5) and three downgradient monitoring wells (MW-6, MW-7, and MW-8). Four assessment monitoring wells (AMW-1S, AMW-1D, AMW-2S, and AMW-2D) are also monitored during each semi-annual monitoring event. Four surface water monitoring points (BR-1, BR-2, BR-3, and SW-1) are monitored semi-annually. Monitoring well and surface water point locations are shown on Figure 1. Compliance wells MW-5, MW-6, MW-7, and MW-8; assessment wells AMW-1 S and AMW-2S; and corrective action monitoring well Old MW-2 are also sampled semi-annually as part of the MNA corrective action. Monitoring wells MW-5, MW-6, MW-7, MW-8, AMW-1S, AMW-2S, and Old MW-2 are screened in the shallow, unconfined aquifer. Monitoring wells AMW-1 D and AMW-2D are screened in fractured bedrock. Available groundwater monitoring well construction information is summarized in Table 3. TVA Well MW-9 is sampled annually (during each first semi-annual event) to monitor groundwater downgradient of the closed TVA landfill. The well is screened in the shallow, unconfined aquifer. 2.2.2 Closed C&D Landfill The network of groundwater monitoring wells at the closed C&D landfill consists of one upgradient monitoring well (MW-10), and three downgradient monitoring wells (MW-11, MW-12, and MW-13). Downgradient monitoring wells MW-10, MW-11, and MW-12 are screened in the shallow, unconfined aquifer. Monitoring well MW-13 is screened in fractured bedrock. The four wells are screened to target the preferential flow path for groundwater underlying the closed C&D waste disposal areas. e aa R June 25, 2021 2.2.3 Groundwater Elevation Measurements 20147157.102 Depth -to -water measurements were recorded to the nearest 0.01 foot prior to initiating groundwater purging and sampling activities. A summary of the current and available historical water level elevations is presented in Table 1. As presented, the data indicate that the hydraulic head level in the uppermost aquifer beneath the facility is consistent, with temporal variation from the long-term average ranging from approximately 2 to 12 feet (plus or minus). As expected, the range in fluctuation is greatest in the upgradient wells MW-5 and MW-10, as these wells are located in groundwater recharge areas. The range of fluctuation in downgradient compliance wells, which are located closer to groundwater discharge areas, is less, presumably due to the stabilizing effect of the hydraulic discharge boundary. 2.3 March 2021 Groundwater and Surface Water Monitoring Event Personnel from Golder visited the facility on March 15 - 16, 2021, to purge and sample the 14 monitoring wells (Old MW-2, MW-5, MW-6, MW-7, MW-8, MW-9, MW-10, MW-11, MW-12, MW-13, AMW-1S, AMW-1D, AMW-2S, and AMW-21D) and to sample four surface water monitoring points (BR-1, BR-2, BR-3, and SW-1). Monitoring wells were purged and sampled using dedicated bladder pumps and low flow techniques. Measurements of pH, specific conductivity, turbidity, dissolved oxygen, temperature, and oxidation reduction potential were recorded after each system volume collected during the purge with field -calibrated instruments to monitor for stabilization of water quality. The purge rate 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 approximately 300 milliliters per minute. Purging was continued until stabilization was indicated by the field parameters. The groundwater samples were collected directly from the bladder pump discharge line in the labelled, laboratory -supplied, pre -preserved sample containers after purging was completed. Each sample container was labelled with the sample identification number, sampling personnel, date and time of sample collection, project name and number, and requested chemical analyses. The surface water samples were collected by lowering the sample containers into the stream flow with the opening facing away from the current flow, taking care to prevent the overflow of the sample containers and to minimize sample -induced turbidity. Measurements of temperature, pH, specific conductivity, dissolved oxygen, oxidation reduction potential, 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 water quality measurements. 2.4 June 2021 Surface Water Verification Monitoring Event Personnel from Golder visited the facility on June 15, 2021, to sample four surface water monitoring points (BR-1, BR-2, BR-3, and SW-1) to verify the March 2021 analytical results for lead. The surface water samples were collected by implementing the same procedures described in Section 2.3. 2.5 Laboratory Analysis Program The March 2021 groundwater and surface water samples were shipped to Environmental Conservation Laboratories, Inc. (ENCO) of Cary, NC under chain -of -custody control. The samples were received at the laboratory March 16 and 17, 2021, in good condition and properly preserved. Additional groundwater samples were shipped to Pace Analytical Energy Services, LLC (Pace) of Pittsburgh, Pennsylvania under chain -of -custody control. The samples were received at the laboratory on March 16, G O..__ June 25, 2021 20147157.102 2021, in good condition and properly preserved. Groundwater samples from MW-5, MW-6, MW-7, MW-8, AMW-1 S, AMW-2S, and Old MW-2 were analyzed for ferrous iron and hydrogen by Pace. The June 2021 surface water samples were shipped to ENCO under chain -of -custody control. The samples were received at the laboratory on June 16, 2021, in good condition and properly preserved. 2.5.1 Closed MSW Landfill Compliance Monitoring Groundwater samples from the compliance MSW wells and the assessment wells were analyzed for the NC Appendix II list of constituents. Surface water samples were analyzed for the NC Appendix I list of constituents. Samples were also analyzed for 1,4-dioxane per the May 29, 2018, NC DEQ memorandum. 2.5.2 Closed C&D Landfill Compliance Monitoring Groundwater samples from the closed C&D facility were analyzed for the NC Appendix I list of constituents, 2,4-D, tetrahydrofuran, and indicator parameters specified in Title 15A NCAC 13B.0566. Samples were also analyzed for 1,4-dioxane per the May 29, 2018, NC DEQ memorandum. 2.5.3 Closed MSW Landfill Corrective Action Monitoring Groundwater samples from the MNA evaluation wells MW-5, MW-6, MW-7, MW-8, AMW-1 S, AMW-2S, and Old MW-2 were analyzed for the MNA parameters which included nitrate, nitrite, ferrous iron, sulfate, sulfide, alkalinity, chloride, methane, ethane, ethene, carbon dioxide, and hydrogen. The sample from Old MW-2 was also analyzed for the COCs from the CAP, which include benzene; 1,4-dichlorobenzene; 1,1-dichloroethane; and vinyl chloride. 3.0 LABORATORY AND FIELD QA/QC A field blank was collected by Golder personnel as part of the March 2021 groundwater and surface water sampling event. In addition to the field blank, laboratory -prepared trip blanks accompanied the volatile sample containers for the March 2021 sampling event to and from the laboratory. ENCO analyzed the field blank for the NC Appendix II list of parameters; iron; manganese; 1,4-dioxane, and tetrahydrofuran. The trip blanks were analyzed for NC Appendix II VOCs and/or tetrahydrofuran. Reviews of the laboratory data were performed by Golder (Appendix B). Based on Golder's review of the laboratory data, no 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 for the Closed MSW Landfill As presented on Table 4, cobalt and thallium were detected at estimated concentrations above their respective NC 2L Interim Maximum Allowable Concentrations (IMACs) in the samples from MW-7, MW-8, and AMW-1 S. Cobalt was also detected at an estimated concentration above the IMAC in the sample from TVA well MW-9. Per 15A NCAC 02L .0202 (b)(1), "where the standard (i.e., the NC 2L Standard) for a substance is less than the practical quantitation limit (PQL), the detection of that substance at or above the PQL constitutes a violation of the standard." For cobalt, the groundwater standard is 1 microgram per liter (ug/L) and the PQL is 10 ug/L. For thallium, the groundwater standard is 0.2 ug/L and the PQL is 2 ug/L. As presented, the cobalt and thallium concentrations mentioned above were reported below the PQL and are considered estimated; no further action is recommended for estimated concentrations. A desktop study of the prevalence of cobalt and thallium in soil and sediment in the general proximity of the Henderson County MSW Landfill using the United State Geological Survey (USGS) National Geochemical 4`' GO..DE June 25, 2021 20147157.102 Survey Database was presented in the First Semi -Annual 2019 Water Quality and Corrective Action Monitoring Report dated July 15, 2019. The study showed that cobalt and thallium occur naturally in stream sediment and is likely to occur in subsurface soil at the Henderson County MSW Landfill at concentrations that would account for the concentrations of these constituents in groundwater. Therefore, the aforementioned exceedances likely originate from natural soils and rock. As presented on Table 4, two NC Appendix II VOCs (benzene and 1,4-dichlorobenzene) were detected at quantifiable concentrations that exceeded the respective NC 2L Standards in the sample from downgradient monitoring well MW-7 at the MSW landfill during the March 2021 event. The constituent 1,4-dioxane was detected at quantifiable concentrations above the NC 2L Standard in samples from MW-7 and AMW-1 D. This constituent was analyzed per the May 29, 2018, NC DEQ memorandum for all permitted landfills; this constituent is not required by regulation or the facility permit. As presented in Table 6, lead was detected at quantifiable concentrations above the surface water standard in the samples from surface water monitoring points BR-1 and SW-1 during the March 2021 event. Lead was also detected at estimated concentrations above applicable surface water standards in the samples from surface water monitoring points BR-2 and BR-3 during the March 2021 event. The surface water samples were relatively turbid at each of the sampling locations and entrained sediment was likely biasing the lead concentrations high. Each surface water location was resampled for analysis of lead during a verification event on June 15, 2021; lead was not detected above the method detection limit in any of the samples, which is consistent with historical data. No NC Appendix I VOCs were detected at concentrations above the applicable surface water standards. 1,4-dioxane was detected at a quantifiable concentration above the applicable surface water standard in the sample from BR-2 as it has been historically. 4.2 North Carolina Groundwater Standard Comparisons for the Closed C&D Landfill As presented in Table 8, no NC Appendix I inorganic constituents were reported in samples collected from monitoring wells at quantifiable concentrations that exceeded applicable groundwater standards at the C&D landfill during the March 2021 event. Cobalt was reported at estimated concentrations above the IMAC in the samples from downgradient wells MW-11 and MW-13. Per 15A NCAC 02L .0202 (b)(1), "where the standard (i.e., the NC 2L Standard) for a substance is less than the practical quantitation limit (PQL), the detection of that substance at or above the PQL constitutes a violation of the standard." For cobalt, the groundwater standard is 1 microgram per liter (ug/L) and the PQL is 10 ug/L. As presented, the cobalt concentrations mentioned above are below the PQL and are considered estimated and therefore, no further action is warranted. The indicator parameter iron was reported at quantifiable concentrations above the NC 2L Standard in samples from downgradient monitoring wells MW-11 and MW-13. The indicator parameter manganese was reported at quantifiable concentrations above the NC 2L Standard in samples from downgradient monitoring wells MW-11, MW-12, and MW-13. Total Dissolved Solids (TDS) was reported at a quantifiable concentration that exceeded the NC 2L Standard in the samples from MW-11 and MW-12 and sulfate was detected at a quantifiable concentration above the NC 2L Standard in the sample from MW-11. The concentrations of these indicator parameters are similar to historical results for the C&D facility monitoring wells. A desktop study of the prevalence of cobalt, iron, and manganese in soil and sediment in the general proximity of the Henderson County MSW Landfill using the USGS National Geochemical Survey Database was presented in the First Semi -Annual 2019 Water Quality and Corrective Action Monitoring Report dated July 15, 2019. The study showed that cobalt and thallium occur naturally in stream sediment and is likely to 4 aa�!R June 25, 2021 20147157.102 occur in subsurface soil at the Henderson County MSW Landfill at concentrations that would account for the concentrations of these constituents in groundwater. Therefore, the aforementioned exceedances likely originate from natural soils and rock. As presented in Table 8, one NC Appendix I VOC, vinyl chloride, was detected at a quantifiable concentration above the NC 2L Standard from downgradient well MW-13 during the March 2021 event at the C&D landfill, as it has been historically. Vinyl chloride was also detected at an estimated concentration above the NC 2L Standard in the sample from downgradient well MW-12 during the event. Per 15A NCAC 02L .0202 (b)(1), "where the standard (i.e., the NC 2L Standard) for a substance is less than the practical quantitation limit (PQL), the detection of that substance at or above the PQL constitutes a violation of the standard." The groundwater standard for vinyl chloride is 0.03 micrograms per liter (ug/L) and the PQL for cobalt is 10 ug/L. As presented, the vinyl chloride concentration in the sample from MW-12 was reported below the PQL and is considered estimated. On September 28, 2010, the County submitted an ASD to NC DEQ in response to VOC concentrations detected in samples from the closed C&D landfill downgradient monitoring wells. Based on the data and evaluations from the ASD, it was apparent that leachate from the C&D disposal unit is not the likely source of the VOC concentrations. Additionally, the data suggest that the source of the VOCs in samples from the monitoring wells is most likely landfill gas. Concentrations of vinyl chloride samples from MW-12 and MW-13 have shown a declining trend for the last 7 years. 1,4-dioxane was detected at a quantifiable concentration above the NC 2L Standard in the sample from MW-12. Samples were analyzed for 1,4-dioxane per the May 29, 2018, NC DEQ memorandum; this constituent is not required by regulation or the facility permit. 5.0 CORRECTIVE ACTION PERFORMANCE MONITORING A Corrective Action Performance Monitoring Plan (CAPMP) was approved as part of the CAP by the NC DEQ on July 13, 2015. Per the CAPMP, MNA background sampling began during the September 2015 semi-annual water quality event and the ninth MNA background event was performed during the March 2020 semi-annual water quality event. A request to modify the MNA parameter list was submitted to the NC DEQ on July 26, 2017 and was approved on September 19, 2017. The modified MNA list consists of sampling alkalinity, carbon dioxide, chloride, ethane, ethene, methane, hydrogen, ferrous iron, nitrate, and sulfate, semi-annually and sampling biological oxygen demand (BOD), chemical oxygen demand (COD), nitrite, sulfide, total organic carbon (TOC), and volatile fatty acids (VFAs), semi-annually every three years and were sampled during the March 2020 event. A CAER for the MNA program was submitted to the NC DEQ on September 4, 2020. The 2020 CAER proposed that tetrachloroethene and trichloroethene be removed as COCs. The 2020 CAER was approved by the NC DEQ on September 9, 2020. A CAER for the SAW pilot test was submitted to the NC DEQ on October 25, 2019. The CAER proposed that methylene chloride be removed as a COC and that SAW injections cease unless VOCs are detected above the NC 2L Standard in samples from groundwater monitoring wells screened in the partially weathered rock / fractured bedrock aquifer. The CAER was approved by the NC DEQ on November 5, 2019. 5.1 Monitored Natural Attenuation The MNA sampling results and evaluation are described below. 5.1.1 Monitored Natural Attenuation Sampling Results During the March 2021 event, the samples from MW-5, MW-6, MW-7, MW-8, AMW-1 S, AMW-2S and Old MW-2 were analyzed for the modified MNA parameter list above. A summary of the MNA parameters is included as Table 10 and the certificates -of -analyses are included in Appendix B. GO__ June 25, 2021 20147157.102 The sample from Old MW-2 was also analyzed for the revised COC list, which include benzene; 1,4-dichlorobenzene; 1,1-dichloroethane; and vinyl chloride. These constituents were analyzed in the other wells as part of the NC Appendix I and II lists of constituents for the routine semi-annual water quality monitoring. A summary of the COCs is included as Table 11 and the certificates -of -analyses are included in Appendix B. Benzene and 1,4-dichlorobenzene were detected at quantifiable concentrations that exceeded their respective NC 2L Standards in the sample from downgradient monitoring well MW-7 during the March 2021 event. No other COCs were detected at concentrations above the NC 2L Standards during the March 2021 event. 5.1.2 Monitored Natural Attenuation Sampling Evaluation Monitoring wells MW-7, MW-6, MW-8, and Old MW-2 were selected for a performance evaluation of MNA processes to adhere to the NC DEQ guidance document titled MNA Excerpt from Examples of Approved Groundwater Corrective Measures for Solid Waste Management Facilities. These wells have been selected because they are located in the area identified for corrective action by MNA in the June 2015 CAP. The March 2021 analytical data for these wells were evaluated using the Environmental Protection Agency (EPA)'s Natural Attenuation Screening Protocol (1999). Based on the EPA's screening protocol, monitoring wells MW-6 received a score of 6, Old MW-2 received a score of 8, MW-7 received a score of 9, and MW-8 received a score of 14, indicating limited evidence for anaerobic biodegradation of chlorinated organics (EPA, 1999). The natural attenuation screening protocol forms are included in Appendix C. It should be noted that the scoring is biased low due to abbreviated MNA list that the samples were analyzed for during the March 2021 event. Based on the results of the screening protocol, there is evidence that natural attenuation is occurring at the site; therefore, modelling was performed on the March 2021 data to simulate remediation by natural attenuation using a screening model called BIOCHLOR (EPA, 2000). Monitoring wells MW-7, MW-6, MW-8, and Old MW-2 were used in the model. Modelling parameters for advection, dispersion, and modelled area were the same as previous models performed for the site, done as part of an MNA evaluation in the NES. A 61-year simulation period was selected for the model, representing the time at which waste was first placed in the landfill (the original source). The March 2021 results represent current conditions at the facility and therefore, the model was calibrated to the current sample results by adjusting the biotransformation data within a prescribed range specified by literature values within the BIOCHLOR program. Once the model was calibrated a forecasted model was created by changing the simulation period to 100 years to assess the size of the contaminant plume in the future. BIOCHLOR generates plots that compare concentrations of tetrachloroethene, trichloroethene, dichloroethene, vinyl chloride, and ethene over time with no degradation to concentrations where sequential 1st order decay is occurring. The plots are provided in Appendix C. The centerline plots can be used to forecast the contaminant plume size over time. Because tetrachloroethene and trichloroethene were not detected in samples from downgradient monitoring wells MW-7, MW-6, MW-8, and Old MW-2 during the March 2021 monitoring event, the BIOCHLOR model could not be calibrated; however, the absence of tetrachloroethene and trichloroethene in these downgradient samples could be considered evidence of biodegradation. Vinyl chloride and ethene were not detected in samples from these wells during the March 2021 event. Dichloroethene was detected in the sample from MW-7. The results from these plots indicate that natural attenuation is occurring at the site and that as long as conditions at the site continue to be strongly anaerobic, biodegradation will likely continue. According to the current data, it is likely that the plume size has stabilized, as indicated by the BIOCHLOR model. 4a o!R June 25, 2021 20147157.102 5.2 Super Aerated Water Pilot Test Sampling Results The most recent SAW pilot test injection occurred in March 2019. SAW injections have ceased unless VOCs are detected above the NC 2L Standard in samples from groundwater monitoring wells screened in the partially weathered rock / fractured bedrock aquifer (AMW-1 D and AMW-2D). As presented in Table 11, no COCs were detected at concentrations above their respective groundwater standards in samples from groundwater monitoring wells screened in the partially weathered rock / fractured bedrock aquifer during the March 2021 event. The certificates -of -analyses for each event are included in Appendix B. 6.0 CONCLUSIONS Due to the presence of VOCs above applicable groundwater standards, Henderson County will continue to monitor the uppermost aquifer beneath the MSW landfill in accordance with the requirements of the Assessment Monitoring Program as outlined in Title 15A NCAC 13B.1634. MNA monitoring events have been performed as outlined in the approved CAP. SAW pilot test injections are no longer required unless VOCs are detected above the NC 2L Standards in samples from groundwater monitoring wells screened in the partially weathered rock / fractured bedrock aquifer. Benzene and 1,4-dichlorobenzene in the sample from MW-7 were the only NC Appendix II VOCs detected at quantifiable concentrations above groundwater standards in samples from MSW downgradient wells during the March 2021 event. An ASD was submitted to NC DEQ on September 28, 2010, to address the source of the VOCs in samples from the closed C&D landfill wells. Based on the data and evaluations from the ASD, it is apparent that leachate from the C&D unit is not the likely source of the VOC concentrations that have been detected in the C&D landfill downgradient monitoring wells. Additionally, the data suggest that the source of the VOCs detected in these monitoring wells is most likely landfill gas. However, a letter from NC DEQ dated May 12, 2011, instructed the County to initiate an Assessment Monitoring Program for the C&D facility. Vinyl chloride in the sample from MW-13 was the only NC Appendix I VOC that was detected at a quantifiable concentration above groundwater standards in samples from C&D downgradient monitoring wells during the March 2021 event. Based on the results summarized herein, the County will continue the implementation of groundwater corrective action at the MSW landfill in accordance with the approved CAP. The County will also continue monitoring the C&D landfill in accordance with the requirements of the Assessment Monitoring Program as outlined in Title 15A NCAC 13B.0545. The next compliance monitoring event for this facility is tentatively scheduled for September 2021. 7.0 REFERENCES Butler, J.R., and D.T. Secor, Jr., 1991. The Central Piedmont (Chapter 4) in J.W.

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, Amanda L. Gaines 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 97 PROJECT NARRATIVE Date: March 31, 2021 Client: Golder Associates, Inc. (G0007) Project: Henderson Co. LF Lab ID: CE02068 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 1,1,1-Trichloroethane and Chloroform; however these analytes were detected in the CRL standard, verifying instrument sensitivity. The LCS exhibited a high bias for 2-Butanone and Isobutyl alcohol; however, these analytes were not detected in the associated samples. The Continuing Calibration Verification (CCV) exhibited a high bias for 1, 1, 1 -Trichloroethane, 1, 1 -Dichloroethane, 1,1-Dichloroethene, 1, 1 -Dichloropropene, 1,2-Dichloropropane, 1,2-Dichloroethane, , 2,2-Dichloropropane, 2-Butanone, 3-Chloropropene, 4-Methyl-2-pentanone, Acetone, Acetonitrile, Acrolein, Acrylonitrile, Benzene, Bromochloromethane, Bromomethane, Carbon disulfide, Carbon Tetrachloride, Chloroethane, Chloroform, Chloromethane, Chloroprene, cis- 1,2-Dichloroethene, cis-1,3-Dichloropropene, lodomethane, Isobutyl alcohol, Methacrylonitrile, Methyl Methacrylate, Methylene chloride, Propionitrile, Tetra hyd rofu ran, trans- 1,2-Dichloroethene, Trichloroethene, Trichlorofluoromethane, Vinyl acetate, and Vinyl chloride; however, these analytes were not detected in the associated samples. The spike recoveries for Chlorobenzene, Trichloroethene, 1, 1 -Dichloropropene, Bromochloromethane, Chlorobenzene, lodomethane, Methylene chloride, Trichloroethene, and Vinyl chloride were outside control limits for the MS and/or MSD samples, the precision between duplicate spikes of Chloroprene exceeded acceptance criteria. The QC batches were approved based on acceptable LCS recovery of these analytes. The spike recoveries for 2-Butanone and Isopropyl alcohol were outside control limits for the MS and/or MSD samples; however, these analytes were not detected in the associated samples. The 8270E Continuing Calibration Verification (CCV) exhibited a high bias for 7,12-Dimethylbenz(a)anthracene, Chlorobenzilate, Methapyrilene, and Phenacetin; however, these analytes were not detected in the associated samples. The 8151 A precision between duplicate spikes of 2,4-D exceeded acceptance criteria. The QC batches were approved based on acceptable LCS recovery of these analytes. The spike recoveries for Arsenic, Iron, and Manganese were outside control limits for the MS, MSD, and/or Post Digestion spike samples. The QC batches were approved based on acceptable LCS recovery of these elements. Quality Control Remarks The 8081 B surrogate spike recovery of Decachlorobiphenyl was outside of acceptance criteria. The samples were approved based on the recoveries of other surrogate standards 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 88 of 97 (� �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. 1-06 The associated laboratory control sample exhibited low bias; the reported result should be considered to be a minimum estimate. 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. QM-08 Post -digestion spike did not meet method requirements due to confirmed matrix effects (dilution test). QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits. QS-03 Surrogate recovery outside acceptance limits QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there is no impact.

TM Proper EPA SW-846 analytical methods were used for analysis. 5.0 DATA REPORTING TM All analytical reporting associated with the event was performed by the contracted lab. TM 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 S 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. TM 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 lax 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. r Antimony and Thallium 2x in all points TM The report provides the reporting limit for each constituent. TM The results were reported at or below their proper reporting limits (i.e., MDLs with PQLs reported). Those that are not reported correctly are listed below (by constituent) with the proper reporting limit listed beside them_ Mate if the reporting limit error is due to dilutions. TM No inorganic 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.

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 1, 1 -Dichloroethane, Trichloroethene, and Vinyl chloride; however, these analytes were not detected in the associated samples. The spike recoveries for Chlorobenzene and Trichloroethene were outside control limits for the MS and/or MSD samples. The QC batches were approved based on acceptable LCS recovery of these analytes. The LCS exhibited a high bias for Nitrite; however, these analytes were not detected in the associated samples. The spike recoveries for Chloride, Nitrate/Nitrite, and Sulfate were outside control limits for the MS and/or MSD samples. The QC batches were approved based on acceptable LCS recovery of these analytes. Quality Control Remarks The precision between duplicate samples for Carbon dioxide was outside of acceptance limits. 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.

I Page 16 of 19 (� �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. 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. QM-12 Precision between duplicate samples was outside acceptance limits. QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there is no impact.

TM Surrogate recoveries for each method are within the acceptable limits (i.e., at least 50% of the surrogates were within range). TM MS/MSD/LCS data results are provided for each analytical method. TM MS/MSDILCS recoveries for each method are within the acceptable limits (i.e., at least 1 of the 3 were within range). r The 8260D Continuing Calibration Verification (CCV) exhibited a high bias for 1,1-Dichlaroethane, Trichloroethene, and Vinyl chloride; however, these analytes were not detected in the associated samples. The spike recoveries for Chlorobenzene and Trichloroethene were outside control limits for the MS and/or MSD samples, The CSC batches were approved based on acceptable LCS recovery of these analytes. f The LCS exhibited a high bias for Nitrite; however, these analytes were not detected in the associated samples. The spike recoveries for Chloride, Nitratefttrfte, and sulfate were outside control limits for the MS and/or MSD samples. The QC batches were approved based on acceptable LCS recovery of these analytes. The precision between duplicate samples for Carbon dioxide was outside of acceptance limits. 4.0 ANALYTE LISTS/MF-THQDS TM The proper number of constituents are present for each analyte list as identified above (including detects where applicable). TM proper EPA SW-845 analytical methods were used for analysis. 510 DATA REPORTING TM All analytical reporting associated with the event was performed by the contracted lab. COLDER ASSOCIATES INC, QUALITY ASSURANCE & QUALITY CONTROL LABORATORY DATA REVIEW C O L D E R Page 3 of 3 k> MEMBER OF WSP TM 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 '13' 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. TM 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. Chloride: 2x @ MW-7 Total Alkalinity 5x @ MW-7, MW-8 TM The report provides the reporting limit for each constituent TM 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. TM No organic constituents were reported above their respective SWSLs, and no inorganic 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. TM No inorganic and 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), TM Other report issues/Communications with laboratory/etc.: aceAnalyfical LELAP CERTIFICATE NUMBER: 01955 DOD-ELAP ACCREDITATION NUMBER: 74960 ANALYTICAL RESULTS PERFORMED BY Pace Analytical Gulf Coast 7979 Innovation Park Dr. Baton Rouge, LA 70820 (225) 769-4900 Report Date 03/17/2021 Report Y 211031583 �1��i �1��i �1��i �1��i �1��i �1��i �1��i �1��i �1��i III Project Henderson Co / 20147157.101 Deliver To Additional Recipients David Reedy NONE Golder Associates 5B Oak Branch Dr Greensboro, NC 27407 336-852-4904 PJLA Tcstiog 114U ELAP Pace Gulf Coast Report#: 221031582 Page 1 of 13 0-1?

LF C&D Lab ID: CE02069 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. The 8260D LCS exhibited a low bias for 1,1,1-Trichloroethane and Chloroform; however these analytes were detected in the CRL standard, verifying instrument sensitivity. The LCS exhibited a high bias for 2-Butanone; however, this analyte were not detected in the associated samples. The Continuing Calibration Verification (CCV) exhibited a high bias for 2-Butanone, lodomethane, and Tetrahydrofuran; however, these analytes were not detected in the associated samples. The spike recoveries for Chlorobenzene, lodomethane, and Trichloroethene were outside control limits for the MS and/or MSD samples, the precision between duplicate spikes of 1,2-Dibromethane and lodomethane exceeded acceptance criteria. The QC batches were approved based on acceptable LCS recovery of these analytes. The spike recovery for 2-Butanone was outside control limits for the MS and/or MSD sample; however, this analyte was not detected in the associated samples. The precision between duplicate spikes of 2,4-D exceeded acceptance criteria. The QC batches were approved based on acceptable LCS recovery of this analyte. The spike recoveries for arsenic and Manganese were outside control limits for the MS, MSD, and/or Post Digestion spike samples. The QC batches were approved based on acceptable LCS recovery of these elements. The spike recoveries for Chloride and Sulfate were outside 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 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 29 Of 32 (� �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. 1-06 The associated laboratory control sample exhibited low bias; the reported result should be considered to be a minimum estimate. 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. QM-08 Post -digestion spike did not meet method requirements due to confirmed matrix effects (dilution test). QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits. QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there is no impact.

TM Proper EPA SW-846 analytical methods were used for analysis. 5.0 DATA REPORTING TM All analytical reporting associated with the event was performed by the contracted lab. TM 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. TM 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 1Ox 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.
