(Golder) is submitting this Water Quality Monitoring Report, which documents the results of the compliance monitoring and corrective action monitoring results from the September 23 - 24, 2020, groundwater and surface water sampling and analysis event. At the closed MSW facility, No NC Appendix I inorganic constituents were reported at quantifiable concentrations that exceed applicable groundwater protection standards in the samples from downgradient monitoring wells during the September 2020 event. Cobalt and thallium were detected at estimated concentrations above their respective 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, during the 2020 second semi-annual water quality monitoring event, the cobalt and thallium concentrations are below their respective PQLs and are considered estimated; therefore, no further action is warranted. In the First Semi -Annual 2020 Water Quality Monitoring Report and Corrective Action Monitoring Report, a desktop study of the prevalence of cobalt and thallium in soil and sediment in the general proximity of the Henderson County MSW Landfill 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. Further, cobalt and thallium have periodically been detected in upgradient well MW-5. Therefore, the aforementioned exceedances are likely naturally occurring. At the closed 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 September 2020 event. Vinyl chloride was also detected at an estimated concentration below the PQL but above the NC 2L Standard at MW-7. 1,4-dioxane was detected at quantifiable concentrations above the NC 2L Standard in samples from one or more downgradient monitoring wells at the MSW landfill during the September 2020 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 closed C&D facility, No NC Appendix I inorganic constituents were reported at quantifiable concentrations that exceed applicable groundwater protection standards in the samples from downgradient monitoring wells. Cobalt was detected at estimated concentrations above the applicable groundwater standard in samples from downgradient wells. As described above, no further action is recommended for these estimated concentrations of cobalt. 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 above the NC 2L Standard in the samples from MW-11 and MW-12. In the First Semi -Annual 2020 Water Quality Monitoring Report and Corrective Action Monitoring Report, a desktop study of the prevalence of cobalt, thallium, iron, and manganese in soil and sediment in the general ,> GOLDER December 30, 2020 20147157.101 proximity of the Henderson County MSW Landfill 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 (Golder, 2020). Therefore, the aforementioned exceedances may be naturally occurring. At the C&D facility, one NC Appendix I VOC, vinyl chloride, was detected at a quantifiable concentration above the NC 2L Standard in the sample from downgradient well MW-13 during the September 2020 event. Vinyl chloride was also detected at an estimated concentration above the NC 2L Standard in the sample from downgradient well MW-12. 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 most likely landfill gas. Concentrations of VOCs at C&D wells are generally consistent or declining. 1,4-dioxane was detected at concentrations above the NC 2L Standard at MW-7 and AMW-1 D during this event. As mentioned above, 1,4-dioxane is not part of the approved monitoring plan but was analyzed per the May 29, 2018, NC DEQ memorandum. No NC Appendix I constituents were detected at concentrations above applicable surface water standards in the samples from surface water monitoring points during the September 2020 event. 1,4-dioxane was detected at a quantifiable concentration above the applicable surface water standard in the sample from BR-2 and at estimated concentrations above the applicable surface water standard in the samples from BR-1, BR-3, and SW-1. As mentioned above, 1,4-dioxane is not part of the approved monitoring plan but was analyzed per the May 29, 2018, NC DEQ memorandum. 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 March 2021. > GOLDER December 30, 2020 20147157.101 Table of Contents 1.0

summarizes the monitoring results from the September 23 — 24, 2020, groundwater and surface water sampling and analysis 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 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 > GOLDER December 30, 2020 20147157.101 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. 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. 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 each of the first semi-annual compliance event each year. 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 requires 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 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 Corrective Action Evaluation Report (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 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 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 CAER proposed that tetrachloroethene and trichloroethene be removed as a COC. The CAER was approved by the NC DEQ on September 9, 2020. ,> GOLDER December 30, 2020 20147157.101 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 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 Ieachate 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. 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 11 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 11 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 2020 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 September 2020 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 0.26 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 ,> GOLDER December 30, 2020 20147157.101 where Vgw = average linear velocity (feet/year), K = hydraulic conductivity (feet/year), i = horizontal hydraulic gradient, and ne = effective porosity. The average estimated linear groundwater flow velocity under the 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 226 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 September 2020 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 September 2020 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-1 S, AMW-1 D, 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-1 S, 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 (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. > GOLDER December 30, 2020 20147157.101 2.2.3 Groundwater Elevation Measurements 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 fairly 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 September 2020 Groundwater and Surface Water Monitoring Event Personnel from Golder visited the facility on September 23 - 24, 2020, to purge and sample the 13 monitoring wells (Old MW-2, MW-5, MW-6, MW-7, MW-8, MW-10, MW-11, MW-12, MW-13, AMW-1 S, AMW-1 D, AMW-2S, and AMW-2D) at the closed MSW and C&D landfills and to sample four surface water monitoring points (BR-1, BR-2, BR-3, and SW-1). All 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 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 Laboratory Analysis Program The September 2020 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 September 24 and 25, 2020, in good condition and properly preserved. Additional MNA groundwater samples were shipped to Pace Analytical Energy Services, LLC (Pace) of Baton Rouge, Louisiana, under chain -of -custody control. The samples were received at the laboratory on September 24, 2020, in good condition and properly preserved. Groundwater samples from MW-5, MW-6, MW-7, MW-8, AMW-1S, AMW-2S, and Old MW-2 were analyzed for ferrous iron and hydrogen by Pace. ,> GOLDER December 30, 2020 20147157.101 2.4.1 Closed MSW Landfill Compliance Monitoring Groundwater samples from the compliance MSW wells and the assessment wells were analyzed for the NC Appendix I list of constituents plus mercury. Surface water samples BR-1, BR-2, BR-3, and SW-1, 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. 2.4.2 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; 1,4-dioxane; and indicator parameters specified in Title 15A NCAC 13B.0566. 2.4.3 Closed MSW Landfill Corrective Action Monitoring Groundwater samples from the MNA evaluation wells MW-5, MW-6, MW-7, MW-8, AMW-1S, AMW-2S, and Old MW-2 were analyzed for MNA parameters, which include 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 constituents -of -concern (COCs) from the CAP, which include benzene; 1,4-dichlorobenzene; 1,1-dichloroethane; methylene chloride; and vinyl chloride. LABORATORY AND FIELD QA/QC A field blank was collected by Golder personnel as part of the September 2020 groundwater and surface water sampling event. In addition to the field blank, laboratory -prepared trip blanks accompanied the volatile sample containers for the September 2020 sampling event to and from the laboratory. ENCO analyzed the field blank for the NC Appendix I list of parameters, mercury, iron, manganese, 1,4-dioxane, 2,4-D, and tetrahydrofuran. The trip blanks were analyzed for NC Appendix I VOCs and tetrahydrofuran. Reviews of the laboratory data were performed by Golder (Appendix B). Based on Golder's review of the laboratory data, estimated concentrations of copper and acetone were detected in the field blank. The following concentrations are considered blank -qualified: copper in the samples from MW-5, MW-6, MW-10, AMW-1 S, and AMW-2D; acetone at MW-8. 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 in Table 4, No NC Appendix I inorganic constituents were reported at quantifiable concentrations that exceed the applicable groundwater protection standards in the samples from downgradient monitoring wells during the September 2020 event. Cobalt and thallium were detected at estimated concentrations above their respective 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, during the 2020 second semi-annual water quality monitoring event, the cobalt and thallium concentrations are below their respective PQLs and are considered estimated; therefore, no further action is warranted. In the First Semi -Annual 2020 Water Quality Monitoring Report and Corrective Action Monitoring Report, a desktop study of the prevalence of cobalt and thallium in soil and sediment in the general proximity of the Henderson County MSW Landfill shows that cobalt and thallium occur naturally in stream sediment and is > GOLDER December 30, 2020 20147157.101 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 (Golder, 2020). Further, cobalt and thallium have periodically been detected in upgradient well MW-5. Therefore, the aforementioned exceedances are likely naturally occurring. As presented on Table 4, two NC Appendix I 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 September 2020 event. Vinyl chloride was detected at an estimated concentration that exceeded the NC 2L Standard in the sample from MW-7. 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. The concentrations of 1,4-dioxane can vary seasonally and will continue to be evaluated. As presented in Table 6, no NC Appendix I constituents were detected at concentrations above applicable surface water standards in the samples from surface water monitoring points during the September 2020 event. 1,4-dioxane was detected at a quantifiable concentration above the applicable surface water standard in the sample from BR-2. 1,4-dioxane was also detected at estimated concentrations above the applicable surface water standard in the samples from BR-1, BR-3, and SW-1. As mentioned above, this parameter is not part of the facility's approved monitoring plan. 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 September 2020 event. Cobalt was reported at an estimated concentration above the IMAC in the samples from downgradient wells MW-11 and MW-13. As presented, during the 2020 second semi- annual water quality monitoring event, the cobalt concentrations mentioned above were reported below the PQL and are considered estimated; no further action is required as described above. 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 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. In the First Semi -Annual 2020 Water Quality Monitoring Report and Corrective Action Monitoring Report, a desktop study of the prevalence of cobalt, thallium, iron, and manganese in soil and sediment in the general proximity of the Henderson County MSW Landfill 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 (Golder, 2020). Therefore, the aforementioned exceedances may be naturally occurring. As presented in Table 8, one NC Appendix I VOC, vinyl chloride, was detected at a quantifiable concentration above the NC 2L Standard in the sample from downgradient well MW-13 during the September 2020 event at the C&D landfill. Vinyl chloride was also detected at an estimated concentration above the NC 2L Standard in the sample from downgradient well MW-12. As presented, during the 2020 second semi-annual water quality monitoring event, the vinyl chloride concentration mentioned above in downgradient monitoring well MW-12 was reported below the PQL and is considered estimated; no further action is required as described above. ,> GOLDER December 30, 2020 20147157.101 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 VOCs at C&D wells are generally consistent or declining. 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. The concentrations of 1,4-dioxane can vary seasonally and will continue to be evaluated. 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 eleventh MNA background event was performed during the September 2020 semi-annual water quality event. A CAER for the MNA program was submitted to the NC DEQ on September 4, 2020. The CAER proposed that tetrachloroethene and trichloroethene be removed as a COC. The 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 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 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 The eleventh MNA sampling event was performed during the September 2020 event. Per the CAPMP, monitoring well Old MW-2 was sampled in addition to the MSW compliance monitoring wells. 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. The sample from Old MW-2 was also analyzed for the COCs from the CAP, which include benzene; 1,4-dichlorobenzene; 1,1-dichloroethane; methylene chloride; and vinyl chloride. These constituents were analyzed in the other wells as part of the NC Appendix I list 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 September 2020 event. No other COCs were detected at concentrations above the NC 2L Standards during the September 2020 event. Vinyl chloride was detected at an estimated concentration that exceeded the NC 2L Standard in the sample from MW-7. ,> GOLDER December 30, 2020 20147157.101 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 September 2020 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, MW-7, MW-8, and Old MW-2 received scores of 16, 16, 18, and 15, respectively, indicating adequate evidence for anaerobic biodegradation of chlorinated organics (EPA, 1999). The natural attenuation screening protocol forms are included in Appendix C. 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 September 2020 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 60-year simulation period was selected for the model, representing the time at which waste was first placed in the landfill (the original source). The September 2020 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, trichloroethene, and ethene were not detected in samples from downgradient monitoring wells MW-6, MW-7, MW-8, and Old MW-2 during the September 2020 monitoring event, the BIOCHLOR model could not be calibrated; however, the absence of tetrachloroethene, trichloroethene, in these downgradient samples could be considered evidence of biodegradation. Vinyl chloride and dichloroethene were detected in the sample from MW-7 during the September 2020 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 if 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. 5.2 Super Aerated Water Pilot Test Sampling Results The last 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 (i.e. AMW-1 D and AMW-2D) during the September 2020 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 > GOLDER December 30, 2020 20147157.101 Assessment Monitoring Program as outlined in Title 15A NCAC 13B.1634. MNA monitoring events have been performed as outlined in the approved CAP. Per the October 25, 2019 CAER, 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. 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. The data suggest that the source of the VOCs detected in these monitoring wells is most likely landfill gas. 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 March 2021. r.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.

LF Lab ID: CD13380 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 Total Xylenes; however this analyte was detected in the CRL standard, verifying instrument sensitivity. The LCS exhibited a high bias for 1, 1 -Dichloroethene, Bromomethane, Carbon disulfide, and Vinyl chloride; 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, 4-Methyl-2-pentanone, Acetone, Acrylonitrile, Benzene, Bromochloromethane, Bromodichloromethane, Bromomethane, Carbon disulfide, Chloroethane, Chloroform, Chloromethane, cis- 1,2-Dichloroethene, Idomethane, trans-1,4-Dichloro-2-butene, Trichloroethene, Trichlorofluoromethane, Vinyl acetate, and Vinyl chloride; however, these analytes were not detected in the associated samples. The spike recoveries for Benzene, Chlorbenzene, Toluene, and Trichloroethene were outside control limits for the MS and MSD samples, the precision between duplicate spikes of Benzene, Chlorobenzene, Toluene, and Trichloroethene exceeded acceptance criteria. The QC batches were approved based on acceptable LCS recovery of these analytes. The spike recovery for 1,1-Dichloroethene was outside control limits for the MS and MSD samples, the precision between duplicate spikes of 1, 1 -Dichloroethene exceeded acceptance criteria; however, this analyte was not detected in the associated samples. The 8151 A spike recovery for 2,4-D was outside control limits for the MS sample, the precision between duplicate spikes of 2,4-D exceeded acceptance criteria. The QC batch was approved based on acceptable LCS recovery of this analyte. The spike recovery for Arsenic was outside control limits for the Post Digestion spike sample. The QC batch was approved based on acceptable LCS recovery of this element. 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 54 Of 5J (� �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. 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.

LF MNA Lab ID: CD13382 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 high bias for 1,1-Dichloroethene and Vinyl chloride; however, these analytes were not detected in the associated samples. The Continuing Calibration Verification (CCV) exhibited a high bias for 1, 1 -Dichloroethene, Benzene, Trichloroethene, and Vinyl chloride; however, these analytes were not detected in the associated samples. The spike recoveries for Benzene, Chlorobenzene, Toluene, and Trichloroethene were outside control limits for the MS and MSD samples, the precision between duplicate spikes of Benzene, Chlorobenzene, Toluene, and Trichloroethene exceeded acceptance criteria. The QC batches were approved based on acceptable LCS recovery of these analytes. The spike recovery for 1, 1 -Dichloroethene was outside control limits for the MS and MSD samples, the precision between duplicate spikes of 1, 1 -Dichloroethene exceeded acceptance criteria; however, this analyte was not detected in the associated samples. The Method Blank (MB) had a positive result for Nitrate and Nitrite. Detections of this analyte should be considered to have a possible high bias if the concentration in the sample is not greater than ten times that of the detection in the MB. The LCS exhibited a high bias for Nitrite; any reported result should be considered estimated. The spike recoveries for Nitrate, Nitrite, and Sulfate were outside control limits for the MS and/or MSD samples, the precision between duplicate spikes of Nitrate exceeded acceptance criteria. 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 Sample 4501-Old MW-2 was reanalyzed out of hold for Nitrite due to the LCS and spike recoveries exceeding acceptance criteria, both results are reported. 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.

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. 1-01 Result may be biased high due to positive results in the associated method blank at a concentration above the MDL and/or greater than one-half the MRL. 1-02 Result may be biased high. Associated laboratory control sample (LCS) exceeded the upper control limit. QB-01 The method blank had a positive result for the analyte; however, the concentration in the method blank is less than 10% of the sample result. There is minimal impact to the data. QB-02 The method blank contains analyte at a concentration above the MDL and/or greater than one-half the MRL. The analyte was not detected in the sample. QH-02 Sample analyzed in hold but had QC exceedances. Sample reanalysis was performed out of hold confirming original result. Both results reported. 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-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits. QM-19 The spike recovery was outside acceptance limits for the MS and/or MSD. QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there is no impact.

TM Laboratory blank is interference -free. The Method Blank (MB) had a positive result for Nitrate and Nitrite. Detections of this analyte should be considered to have a possible high bias if the concentration in the sample Is not greater than ten times that of the detection in the MB. The LCS exhibited a high bias for Nitrite; any reported result should be considered estimated. The spike recoveries for Nitrate, Nitrite, and Sulfate were outside control limits for the MS and/or MSD samples, the precision between duplicate spikes of Nitrate exceeded acceptance criteria. 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. TM Surrogate recoveries are provided for each analytical method, where applicable, TM Surrogate recoveries for each method are within the acceptable limits (i,e., at least 50% of the surrogates were within range). TM MS/MS❑/LCS data results are provided for each analytical method. TM MS/MSD/LCS recoveries for each method are within the acceptable limits (i.e., at least 1 of the 3 were within range). f The 8260D LCS exhibited a high bias for 1,1-131chloroethene and Vinyl chloride; however, these analytes were not detected in the associated samples. The Continuing Calibration Verification (CCV) exhibited a high bias for 1,1-Dichloroethene, Benzene, Trichloroethene, and Vinyl chloride; however, these analytes were not detected in the associated samples. The spike recoveries for Benzene, Chlorobenzene, Toluene, and Trichloroethene were outside control limits for the M5 and MSC samples, the precision between duplicate spikes of Benzene, Chlorobenzene, Toluene, and Trichloroethene exceeded acceptance criteria. The QC batches were approved based on acceptable LCS recovery of these anslytes. The spike recovery for 1,1-131chloroethene was outside control limits for the MS and MSD samples, the precision between duplicate spikes of 1,1-Dichloroethene exceeded acceptance criteria; however, this analyte was not detected in the associated samples.

TM Trip, field and/or equipment, and laboratory blank results have all been reported. Ali 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 10X 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 lox 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.

LF C&D Lab ID: CD13381 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 high bias for 1, 1 -Dichloroethene, Acetone, Bromomethane, Trichloroethene, and Vinyl chloride; however, these analytes were not detected in the associated samples. The Continuing Calibration Verification (CCV) exhibited a high bias for 1,1-Dichloroethene, Acetone, Benzene, Bromochloromethane, Bromomethane, Carbon disulfide, Chloroethane, Idomethane, Trichlorofluoromethane, Vinyl acetate, and Vinyl chloride; however, these analytes were not detected in the associated samples. The spike recovery for 1,1-Dichloroethene was outside control limits for the MS and MSD samples; however, this analyte was not detected in the associate samples. The 8151A precision between duplicate spikes of 2,4-D exceeded acceptance criteria. The QC batch was approved based on acceptable LCS recovery of this analyte. The spike recoveries for Chloride and Sulfate were outside control limits for the MS samples. The QC batches were approved based on acceptable LCS recovery of these analytes. Quality Control Remarks The 8151A surrogate spike recovery of 2,4-DCAA was outside of acceptance criteria. 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.

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.
