Box 1927, Carthage, North Carolina, 28327 (hard copy & electronic copy) GOLDER February 21, 2020 Project No. 19127453 Executive Summary On behalf of Moore County, Golder Associates NC, Inc. (Golder) is submitting the enclosed Water Quality Monitoring Report (Report), which documents the results of the November 19 - 21, 2019, assessment and corrective action water quality monitoring event, and the January 8, 2020, verification event, at the Moore County Landfill located in Aberdeen, North Carolina. The November 2019 water quality monitoring event was the fourth assessment monitoring event for the active construction and demolition (C&D) landfill groundwater compliance monitoring network in accordance with the approved Assessment Monitoring Work Plan. Groundwater samples collected from assessment monitoring wells (i.e., active C&D groundwater monitoring wells) during the November 2019 event were analyzed for Appendix I constituents plus previously detected Appendix II constituents (naphthalene and sulfide) and the indicator parameters required by the NC Department of Environmental Quality (DEQ) for C&D landfills [e.g., chloride, manganese, sulfate, iron, alkalinity, total dissolved solids (TDS), and tetrahydrofuran]. During the November 2019 water quality monitoring event, groundwater samples were also collected from monitoring wells associated with the upgradient closed municipal solid waste (MSW) landfill which is currently in corrective action. Per the currently approved Water Quality Monitoring Plan (HDR, July 2006) for the site with the exception of MW-8, all samples from the monitoring wells in the MSW compliance network are considered performance (i.e., MNA) monitoring wells and are currently analyzed for Appendix I volatile organic constituents (VOCs), Resource Conservation and Recovery Act (RCRA) metals, and an approved suite of MNA parameters (which includes chloride, ethane, ethene, methane, nitrate, sulfate, sulfide, total alkalinity, and total organic carbon). In addition, several active C&D monitoring wells including MW-4, MW-5, MW-11SR, MW-14, and MW-17S are also sampled for the same suite of MNA parameters. Samples from monitoring well MW-8 are analyzed for VOCs listed in Appendix I and RCRA metals. Surface water and groundwater samples from both facilities were also analyzed for 1,4-dioxane per the May 29, 2018, memorandum from the NC DEQ. During the November 2019 water quality monitoring event, four surface water samples were collected and analyzed for Appendix I VOCs listed and RCRA metals. A private water supply well located north of the landfill at the Blake residence (an adjacent property) was sampled and analyzed for Appendix I VOCs and RCRA metals. Three (3) inorganic constituents (iron, manganese, and vanadium) were detected at concentrations that exceeded their respective NC 2L Groundwater Standards in samples collected from one or more downgradient C&D monitoring wells during the November 2019 water quality monitoring event. Vanadium was detected at estimated concentrations below the practical quantitation limit (PQL) but above the groundwater standard. In general, the concentrations of detected inorganic constituents during the November 2019 sampling event are similar to historic results for the facility. Two (2) Appendix I organic constituents (benzene and vinyl chloride) were detected in samples from one or more downgradient monitoring C&D monitoring wells at concentrations that exceeded their respective NC 2L Groundwater Standards during this sampling event. Additionally, 1,4-dioxane was detected at concentrations above the NC 2L Groundwater Standard in samples from downgradient wells during this event; this constituent was analyzed per the May 30, 2018, memorandum and is not part of the facility permit -required testing. GOLDER February 21, 2020 Project No. 19127453 As presented, one (1) inorganic constituent (arsenic) was detected at concentrations exceeding the NC 2L Groundwater Standard and PQL in samples collected from one or more downgradient MSW monitoring wells during the November 2019 water quality monitoring event. Three (3) Appendix I organic constituents (benzene, 1,4-dichlorobenzene, and vinyl chloride) were detected at concentrations exceeding their respective NC 2L Groundwater Standards in samples collected from one or more downgradient MSW monitoring wells during this monitoring event. Additionally, 1,4-dioxane was detected at concentrations above the NC 2L Groundwater Standard in samples from downgradient MSW monitoring wells during this event. This constituent was analyzed per the May 30, 2018, memorandum and is not part of the facility permit -required testing. As presented, a verification re -sampling event was conducted on January 8, 2020 due to an anomalous concentration of benzene detected in sample from MW-15R during the November 2019 sampling event; the verification results did not confirm the benzene concentration. Four (4) surface water monitoring points were sampled during the November 2019 monitoring event. One (1) organic constituent (1,4-dioxane) was detected at quantifiable concentration above the surface water standard in samples collected from SW-1, SW-3, and SW-4 during the November 2019 water quality monitoring event. In general, VOC concentrations in groundwater at the site are declining and the number of constituents with detected concentrations above the applicable groundwater standards in the downgradient groundwater monitoring network are decreasing. As presented and based on the results summarized herein, Moore County plans to petition the SWS to return to a Detection Monitoring Program [15A NCAC 13B .0545(b)(9)] at the active C&D landfill through the submittal of an ASD addendum. Based on available data, impacts observed in groundwater at the C&D site appear to originate from the upgradient closed, unlined MSW landfill, which is currently in corrective action. The changes included in the recent Water Quality Monitoring Plan (Golder, 2019) and approved by NC DEQ in a communication dated January 2, 2020, will be incorporated into the next monitoring event (tentatively scheduled for April 2020). Based on the declining COC concentrations in groundwater, the County plans to continue with MNA unless an increase in VOC concentrations is observed or directed to proceed to an alternate groundwater remedy (i.e., Phase 11) by NC DEQ.

The Moore County Landfill is comprised of two waste disposal areas: the active construction and demolition (C&D) landfill located on the western side of the facility and the closed municipal solid waste (MSW) landfill located on the eastern side of the facility. The facility is owned and operated by Moore County (the County) under North Carolina (NC) Solid Waste Permit No. 63-01 issued by the North Carolina Department of Environmental Quality [NC DEQ, formerly known as the NC Department of Environment and Natural Resources (NC DENR)]. 1.1 Site Description and Background The physical location of the Moore County Landfill is shown on the topographic map inlay on Drawing 1. The Moore County Landfill is located in the southwestern part of the Moore County between the towns of Pinehurst and Aberdeen, NC. The site is accessed from State Highway 5, located to the east of the facility. The facility is bound to the west by Horse Creek and to the north and south by unnamed tributaries of Horse Creek. The location of these surface water features is shown on Drawing 1. As presented on Drawing 1, topographic surface elevations at the facility range from approximately 460 feet above mean sea level (AMSL) along the eastern portion of the closed MSW landfill, to approximately 350 feet AMSL in the southwestern portion of the facility. The site is surrounded predominantly by wooded, agricultural, or rural residential properties. As presented, the Moore County Landfill is located on approximately 314 acres and contains a closed MSW landfill unit, an active C&D landfill unit, and several closed land clearing & inert debris (LCID) units. In conjunction with Moore County, Republic Services of NC, LLC operates a solid waste transfer station located on the southwestern portion of the property. The MSW landfill accepted waste from approximately 1968 to 1993 and was closed prior to October 1993, with final closure approval in December 1996; the County expressed their intent to comply with post -closure monitoring regulations in January 1997. The MSW landfill area encompasses approximately 60 acres, 12 of which have a clay cap. The County began transferring MSW in 1993. The County temporarily stockpiled C&D waste from approximately 1993 to 1996, until the current C&D landfill was permitted and built (HDR, 2005). 1.2 Compliance Monitoring History The first water quality monitoring event at the facility was conducted in June 1987 on five monitoring wells (MW-1 through MW-5). Monitoring well MW-5 acts as the facility background well and is located upgradient of the current C&D landfill. Monitoring wells MW-1 through MW-4 were the downgradient monitoring wells in the original groundwater monitoring network. Monitoring wells MW-6 through MW-9 were added in March 1995 to monitor the area between the MSW and the C&D landfill. Groundwater corrective action was initiated voluntarily due to concerns of off -site migration of volatile organic compounds (VOCs) detected in groundwater samples and methane gas. According to available records, concerns of off -site migration of VOCs were first expressed by the NC DEQ in a letter dated January 23, 1996. A private water supply well at the Blake residence (PW-1), located upgradient of the facility, was added to the groundwater monitoring network in 1996, along with upstream and downstream surface water monitoring points (SW-2 and SW-1, respectively). Additional monitoring wells were installed in September 1996 to delineate the nature and extent of groundwater impacts and to serve as monitoring points for the C&D facility. The monitoring wells installed in September 1996 included MW-11 S/D, MW-12S/D, MW-13S/D, and MW-14. Monitoring well GOLDER February 21, 2020 Project No. 19127453 MW-14 was installed upgradient of the C&D landfill (between the MSW and the C&D landfill) and was intended to act as the upgradient monitoring well for the C&D landfill (to differentiate groundwater impacts from the MSW landfill). Monitoring wells MW-11S/D, MW-12S/D, and MW-13S/D were to act as the downgradient monitoring network for the C&D landfill. Monitoring wells MW-16S/D were later installed to replace the downgradient monitoring wells MW-12S/D, which were abandoned during an expansion of the C&D facility. In November 1999, a work plan was submitted to NC DEQ by HDR Engineering Inc. of the Carolinas (HDR) to address off -site groundwater and methane migration concerns. After revisions, the work plan was initiated in March 2000 and water quality assessment activities were commenced. A clay confining unit was identified at depth, which was reported to limit vertical groundwater contamination. In January 2005, NC DEQ requested that Moore County complete an assessment of corrective measures (ACM) and select a remedy in accordance with 15A NCAC 2L .0106. HDR submitted the ACM in July 2005 with monitored natural attenuation (MNA) as the primary proposed remedy with a contingency plan for active landfill gas (LFG) remediation if increasing trends in VOCs were observed in groundwater. NC DEQ approved the recommendations in the ACM on November 21, 2005; however, they did not require a public hearing, as this was not required for this facility under the applicable regulations (HDR, 2005). In 2005, a shallow trench vent network consisting of a trench and 12 passive LFG vents were installed to address LFG migration concerns; this network was expanded with 12 additional LFG vents in 2007. Three in -waste passive gas vents (GV-30, GV-31, and GV-32) were installed in February 2014 as part of the Contingency Plan Update and Implementation Plan -Revised approved by NC DEQ on June 5, 2013. A revised Water Quality Monitoring Plan was prepared in July 2006 and approved October 13, 2006, by NC DEQ. This Plan includes monitoring of NC Appendix I VOCs and RCRA metals for all groundwater and surface water monitoring points, as well as "performance monitoring" (i.e., MNA) parameters for selected wells. In a letter from the NC DEQ dated April 18, 2008, Moore County received permission to eliminate hydrogen, carbon dioxide, and volatile fatty acids from the semi-annual monitoring list, and complete groundwater modeling annually. This letter also specified that the County collect the full suite of "performance monitoring parameters" in April and October 2011, and present a MNA Corrective Action Evaluation Report (CAER) after completion of the October 2011 sampling event. The CAER was submitted in May 2012 and NC DEQ granted the County permission to continue MNA for another five-year period at the end of which the County was required to submit another. In order to better assess surface water quality and potential offsite plume migration two additional surface water points (SW-3 and SW-4) were added to the compliance monitoring network upon approval of the CAER in May 2012. Moore County met with NC DEQ on March 10, 2016 to discuss groundwater impacts at the site and the effectiveness of the previously implemented corrective actions at the facility. In this meeting and in a follow-up, correspondence sent from NC DEQ on March 14, 2016, the Solid Waste Section (the Section) requested that Moore County commence assessment monitoring at the C&D landfill or submit an alternate source demonstration (ASD) to demonstrate the impacts observed in the C&D landfill monitoring network were from a source other than the C&D landfill. On February 28, 2017, the County submitted an ASD for the Active C&D Landfill, identifying the upgradient closed MSW landfill as the source of VOCs at downgradient C&D wells. In two letters dated September 28, 2017, the NC DEQ declined to issue a determination on the ASD for the Active C&D Landfill and requested Moore County implement landfill gas and groundwater corrective action at the closed MSW landfill, as well as commence assessment monitoring as detailed in 15A NCAC 13B .0545 at the active C&D landfill. The County submitted a response to these communications on October 26, 2017 and met with NC DEQ on November 30, 2017. Following this meeting, Moore County submitted a letter on December 6, 2017 GOLDER February 21, 2020 Project No. 19127453 confirming the County's intention to comply with the requests of NC DEQ and requesting an extension to comply. This request was approved by NC DEQ on December 11, 2017. Following the November 30, 2017 meeting with NC DEQ, the County submitted a 2nd CAER (detailing MNA corrective action from April 2012 — October 2016), a Landfill Gas Remediation Plan, a Groundwater Corrective Action Milestone Schedule (including the submission of the NC Solid Waste .0500 Groundwater Corrective Action Application), and an Assessment Monitoring Work Plan. In accordance with the Assessment Monitoring Work Plan, (approved by NC DEQ in a January 23, 2018, correspondence) replacement wells were installed for monitoring wells MW-11 S, MW-11 D, and MW-15 prior to the June 2018 water quality monitoring event. As approved, the replacement wells were sampled during the first assessment monitoring event for the active construction and demolition (C&D) landfill groundwater compliance monitoring network in June 2018. Groundwater samples collected from assessment monitoring wells (i.e., active C&D groundwater monitoring wells) during the June 2018 event were analyzed for the constituents listed in Appendix II and the indicator parameters required by NC DEQ for C&D landfills (e.g., chloride, manganese, sulfate, iron, alkalinity, total dissolved solids (TDS), and tetrahydrofuran. In addition, to further assess whether the groundwater impacts seen at the C&D landfill are attributable to the upgradient MSW landfill, monitoring wells MW-6 and MW-7 were also analyzed for Appendix II constituents. On February 20, 2019 in a letter submitted to NC DEQ by Golder Associates NC, Inc. (Golder) on behalf of Moore County, a request was made to decommission monitoring wells MW-16S and MW-16D and replace them in the groundwater monitoring network with the MW-17S an MW-17D which were installed recently in conjunction with the permitting of Cell VI. The request was approved by NC DEQ in a letter dated February 22, 2019. Monitoring wells MW-16S/D were last sampled in April 2019 prior to decommissioning on May 17, 2019. The November 2019 sampling event was the first sampling event in which monitoring wells MW-17S/D were sampled. During the November 2019 water quality monitoring event, groundwater monitoring was conducted at the closed MSW landfill in accordance with the approved Water Quality Monitoring Plan and Phase I of the Groundwater Corrective Action Milestone Schedule which was approved by NC DEQ on February 13, 2018. Phase I of the Groundwater Corrective Action Milestone Schedule included the following activities: Installation of the methane cut-off trench to the south of MW-15 (completed November 2, 2018) Replacement of MW-15 with MW-15R (completed June 1, 2018) Conversion of MW-15 to a compliance methane monitoring well (completed December 7, 2018) Continuation of MNA (as detailed in the approved Water Quality Monitoring Plan). Per the approved Water Quality Monitoring Plan (HDR, July 2006) for the site, with the exception of MW-8, all samples from the monitoring wells in the MSW compliance network are considered MNA performance monitoring wells and are currently analyzed for VOCs listed in Appendix I, Resource Conservation and Recovery Act (RCRA) metals, and an approved suite of MNA parameters (which includes chloride, ethane, ethene, methane, nitrate, sulfate, sulfide, total alkalinity, and total organic carbon). In addition, several active C&D monitoring wells including MW-4, MW-5, MW-11 SR, MW-14, and MW-17S are also sampled as MNA performance wells for the same suite of MNA parameters. Samples from monitoring well MW-8 are currently only analyzed for VOCs listed in Appendix I and RCRA metals. GOLDER February 21, 2020 Project No. 19127453 In accordance with the NC Solid Waste Rules and the approved Assessment Monitoring Work Plan, upon completion of the fourth assessment background sampling event (i.e., the November 2019 sampling event), a report will be submitted to NC DEQ in accordance with 15A NCAC .0545(b)(7) to be sealed by a licensed geologist as part of the semi-annual report. The concentrations of constituents listed in Appendix II for each background monitoring event will be compared to established 15A NCAC 02L. 0202 groundwater quality standards (NC 2L Groundwater Standards) and interim maximum allowable concentration standards (IMAC Standards). In the case of metals, comparisons will also be made to background concentrations, as appropriate. Pending the results of assessment background sampling, the County may petition the SWS to return to a Detection Monitoring Program [15A NCAC 13B .0545(b)(9)] through submittal of an ASD addendum, request selective Assessment Monitoring for a subset of wells impacted by VOCs and/or a subset of constituents listed in Appendix II for analysis [15A NCAC .0545(b)(6)], or will begin the process to implement an ACM for landfill gas to groundwater impacts [15A NCAC 13B .0545(c)] per the approved Assessment Monitoring Work Plan. The results of this evaluation are presented in Section 5.0 of this report. 1.3 Hydrogeologic Setting The facility is located in the inner Coastal Plain Physiographic Province of NC. The geologic units of this region are relatively young, dating from the Cretaceous to the Tertiary period (NCGS, 1985). The site is underlain by sands, silts, and clays of the Middendorf Formation, which generally consist of intercalated, lenticular, thick - bedded, light-colored sands and clays (mudstones) with local concentrations of clay-clast conglomerates (NCGS, 1985 and Sohl and Owens, 1991). The uppermost groundwater beneath the facility is present in a shallow, unconfined aquifer comprised of sands mixed with thin clay seams and larger seams of fine sand. The uppermost aquifer at the site is approximately 55 feet thick and underlain by a clay confining layer (HDR, 2005). Groundwater occurs at depths varying from approximately 5 to 38 feet below ground surface across the entire site. Measurements of groundwater elevations obtained during the November 2019 water quality monitoring event are summarized in Table 1 and were used to prepare the groundwater surface contour map presented on Drawing 1. Surface water and groundwater at the site generally flows to the west and southwest toward Horse Creek, which is located along the western property boundary. Limited surface water and groundwater flows to the north and south to unnamed tributaries of Horse Creek located along the northern and southern property boundaries. Based on the November 19, 2019 groundwater surface contour map, the hydraulic gradient in the shallow aquifer underlying the site, as measured along the conceptual flow path shown on the contour map was calculated to be approximately 0.018 feet per foot. Groundwater velocities were calculated using a hydraulic conductivity of 3.19 x 10-3 centimeters per second (cm/s), which is the average hydraulic conductivity for the uppermost aquifer as calculated from slug tests performed at the facility. An effective porosity of 0.35 was selected for the shallow aquifer at the site based on typical effective porosity values for similar soil types (HDR, 2005). The groundwater surface contour map and interpreted flow directions are generally consistent with previously submitted interpretations for this facility. 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: GOLDER February 21, 2020 Project No. 19127453 where V9W = average linear velocity (feet/year), K = hydraulic conductivity (feet/year), i = horizontal hydraulic gradient, and ne = effective porosity. The average estimated linear groundwater flow velocity under the waste management units is approximately 174 feet/year, which is slower than previous estimates (Table 2). The inconsistency in the current calculated groundwater flow velocity with previous estimates is due to a change in the hydraulic conductivity value used. The hydraulic conductivity value selected for this calculation incorporates new slug test data from test performed in correlation to the recent submittal of a Design Hydrogeologic Report (Golder, 2019) which was prepared for the proposed Cell VI horizontal expansion. The range of groundwater flow is expected to vary depending on topographic and hydrogeologic conditions. The linear velocity equation above makes the simplified assumptions of a homogeneous and isotropic aquifer. Therefore, this equation represents a presumptive estimated 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. FIELD PROGRAM, MONITORING RESULTS, AND DISCUSSION Field activities conducted for the November 2019 sampling event are discussed in the following sections 2.1 Visual Inspection Program In order detect a potential release at the earliest possible time; a visual inspection program is used at the Moore County closed MSW and active C&D landfills by the sampling personnel. This program includes the examination of physical indicators such as potential water table mounding beneath the waste management unit, visible signs of stress in the onsite 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 November 2019 compliance monitoring event, no physical indicators of a potential release were observed in the vicinity of the waste management areas by Golder sampling personnel. 2.2 Monitoring Well Network and Groundwater Elevation Measurements As presented, there are two groundwater monitoring well networks at the site - one network to monitor groundwater beneath the active C&D landfill and one to monitor groundwater beneath MSW landfill. One background monitoring well, MW-5, provides background data for both groundwater monitoring networks. The approved active C&D landfill groundwater monitoring network consists of eight downgradient monitoring wells (MW-4, MW-11SR, MW-11 DR, MW-13S, MW-13D, MW-17S, and MW-17D) and one additional upgradient monitoring well (MW-14) which monitors groundwater between the adjacent upgradient MSW landfill and the C&D landfill. The closed MSW landfill groundwater monitoring network consists of eight downgradient monitoring wells (MW-1, MW-2, MW-3, MW-6, MW-7, MW-8, MW-9, and MW-15R). In addition, four C&D monitoring wells (MW-4, MW-11 S, MW-14, and MW-17S) are also used as "performance" or "MNA" monitoring wells to assess groundwater impacts from the MSW landfill. Available monitoring well construction information for each groundwater monitoring well is summarized on Table 3 and the well locations are shown on Drawing 1. The groundwater monitoring well locations were selected to yield groundwater samples representative of the conditions in the uppermost aquifer underlying the facility; to monitor for potential releases from the landfill units; and to assess the progress of natural attenuation. As presented, two upstream (SW-1 and SW-2) and two downstream (SW-3 and SW-4) surface water monitoring points, and one private water well (PW-1) are also monitored in accordance with the approved monitoring plan. GOLDER February 21, 2020 Project No. 19127453 Depth -to -water measurements are recorded to the nearest 0.01 foot prior to initiating groundwater purging and sampling activities. The respective groundwater elevations for this event as well as historical groundwater elevation data are presented in Table 1. As presented, recent groundwater elevation data for the groundwater monitoring well network indicate that the hydraulic head level in the uppermost aquifer beneath the facility is fairly consistent, with temporal variation from the long-term average limited to approximately 3 - 12 feet (plus or minus). The range in fluctuation appears to be greatest in the upgradientisidegradient monitoring wells (e.g., MW-5). The range of water table fluctuation in the downgradient compliance wells varies depending on their location, relative to the hydraulic discharge boundary. 2.3 November 2019 Water Quality Monitoring Event Personnel from Golder mobilized to the facility from November 19 - 21, 2019, to purge and sample the seventeen (17) groundwater monitoring wells, to sample four (4) surface water monitoring points, and to sample the Blake residence water well (i.e., PW-1). The monitoring wells were purged and sampled using a portable peristaltic or submersible bladder pump and micro -purge procedures. During the micro -purging process stabilization measurements of temperature, pH, specific conductivity, turbidity, dissolved oxygen, and oxidation reduction potential (ORP) were recorded on approximately 2 to 5-minute intervals, depending on the flow cell volume, system volume, and well yield. Generally, the purge rate for each well was matched to the yield of the monitoring well, as determined by continuously monitoring the depth to the water. Purge rates of up to 300 milliliters per minute were used during the November 2019 sampling event. Each monitoring well was purged until stabilization of the water quality parameters. Prior to sampling, the laboratory -supplied sample containers were prepared. Each sample container was labeled with the sample identification number, sampling personnel, date and time of sample collection, project name and number, and requested chemical analyses. The "performance" or "MNA" monitoring wells identified above were also analyzed for ferrous iron in the field using a HACH field measurement kit. The required groundwater samples were collected directly from the peristaltic or submersible portable pump discharge tubing into the pre -labeled, laboratory -supplied, pre -preserved sample containers after purging was completed based on stabilization of the water quality parameters. After collection, the samples were placed in a cooler on ice, under chain -of -custody control. A summary of the November 2019 groundwater analytical results as well as a summary of the historical groundwater analytical results for the Moore County Landfill are presented in Table 4. The completed groundwater sampling logs are presented in Appendix A. Included in each log is a description of the sampling equipment, methods, location, field observations, and a record of the water quality measurements. A summary of the stabilized groundwater field parameters recorded at the time of sampling is included in this report as Table 5. The surface water samples were collected directly from the stream, by lowering the sample container into the stream flow with the bottle opening facing downstream, the bottles were filled carefully to prevent overflow and to minimize turbidity. Measurements of pH, specific conductivity, temperature, turbidity, dissolved oxygen, and oxygen reduction potential were measured directly from the stream and recorded during the collection of the surface water samples. After collection, the samples were placed in a cooler on ice, under chain -of -custody GOLDER February 21, 2020 Project No. 19127453 control. A summary of the November 2019 surface water analytical results as well as a summary of the historical surface water analytical results for the Moore County Landfill are presented in Table 6. The surface water sampling logs are presented in Appendix A. Included in each log is a description of the sampling equipment, methods, sample location, field observations, and water quality measurements. A summary of the field parameters recorded at the time of surface water sampling is included in this report as Table 7. The sample collected from the Blake residence water well (PW-1) was collected from an outside spigot at the well house by allowing the water to purge for approximately 5 minutes before the sample bottles were filled. As with the groundwater and surface water sampling, a sampling log was completed at the time of sampling describing the sampling equipment, methods, sample location, field observations, and water quality measurements. The completed sampling log is also included in Appendix A and the field parameters recorded at the time of sampling are summarized on Table 5. 2.4 Laboratory Analysis Program The November 2019 groundwater and surface water samples were submitted to Environmental Conservation Laboratories, Inc. (ENCO) of Cary, NC under chain -of -custody control for analysis. As presented, in accordance with the Assessment Monitoring Work Plan groundwater samples collected from the assessment monitoring wells (i.e., active C&D groundwater monitoring wells) during the November 2019 event were analyzed for the constituents listed in Appendix I and detected Appendix II constituents as well as the indicator parameters required by NC DEQ for C&D landfills [e.g., chloride, manganese, sulfate, iron, alkalinity, total dissolved solids (TDS), and tetrahydrofuran]. Per the currently approved Water Quality Monitoring Plan (HDR, July 2006) for the site with the exception of MW-8, all samples from the monitoring wells in the MSW compliance network are considered performance (i.e., MNA) monitoring wells and are currently analyzed for Appendix I VOCs, Resource Conservation and Recovery Act (RCRA) metals, and an approved suite of MNA parameters (which includes chloride, ethane, ethene, methane, nitrate, sulfate, sulfide, total alkalinity, and total organic carbon). In addition, several active C&D monitoring wells including MW-4, MW-5, MW-11 SR, MW-14, and MW-17S are also sampled for the same suite of MNA parameters. Samples from monitoring well MW-8 are analyzed for Appendix I VOCs and RCRA metals. Surface water and groundwater samples were also analyzed for 1,4-dioxane per the May 29, 2018, memorandum from the NC DEQ. Per the laboratory receipt summaries, which can be found at the end of each laboratory certificate -of -analysis in Appendix B, each sample was received at the laboratory in good condition and was properly preserved. 2.5 January 2020 Verification Event Golder personnel mobilized for a second time to the facility on January 8, 2020 to re -sample MW-15R. The verification re -sampling event was conducted to verify an anomalous concentration of benzene observed in monitoring well MW-15R during the November 2019 sampling event. The verification samples from MW-15R were collected utilizing the same methods and procedures as were used during the November 2019 sampling event. After the verification sample was collected, the samples were placed in a cooler on ice, under chain -of - custody control, and sent via carrier to ENCO laboratory in Cary, NC for analysis. A copy of the sampling log is included in Appendix A. As with the November 2019 sampling event, included on the sampling log is a description of the sampling equipment, sampling method, field observations, location, and water quality measurements. GOLDER February 21, 2020 Project No. 19127453 3.0 LABORATORY AND FIELD QA/QC To provide quality assurance and quality control (QA/QC), a field blank was collected by Golder personnel during the November 2019 water quality monitoring event. During the initial sampling event in November 2019 and during the verification sampling event performed in January 2020, a laboratory -prepared trip blank accompanied the volatile organic sample containers throughout the trip from the laboratory, to the site, and eventually back to the laboratory for analysis. ENCO analyzed the field blank for Appendix I VOCs plus Detects and RCRA metals, and the trip blanks for Appendix I VOCs. Reviews of the laboratory data were performed by Golder personnel and are included in Appendix B. DATA EVALUATION The results of the analytical data evaluations are presented in the following sections. A summary of the November 2019 as well as the available historical analytical results is included in Table 4. NC Groundwater Quality Standard Comparisons — C&D Landfill Three (3) inorganic constituents (iron, manganese, and vanadium) were detected at concentrations that exceed their respective NC 2L Groundwater Standard or IMAC in samples collected from one or more downgradient C&D monitoring wells during the November 2019 water quality monitoring event. Below is a summary of the inorganic exceedances of the NC 2L Groundwater Standards (or IMACs) within the active C&D landfill groundwater monitoring network during the November 2019 sampling event. ..

MW-14 is located upgradient of the C&D landfill (between the MSW and the C&D landfill) Vanadium was detected at an estimated concentration above the IMAC but below the PQL. Per 15A NCAC 02L .0202 (b)(1), "where the 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." As referenced, the vanadium concentration detected during the November 2019 sampling event does not constitute a violation of the standard. Two (2) organic constituents (benzene and vinyl chloride) listed in Appendix I, and one additional organic constituent (1,4-dioxane), were detected in samples from one or more downgradient monitoring wells at concentrations exceeding their respective NC 2L Groundwater Standards during this monitoring event.

Below is a summary of the inorganic exceedances of the NC 2L Groundwater Standard within the closed MSW landfill groundwater monitoring network during the November 2019 sampling event. Three (3) organic constituents (benzene, 1,4-dichlorobenzene, and vinyl chloride) listed in Appendix I, and one additional organic constituent (1,4-dioxane) were detected at concentrations exceeding their respective NC 2L Groundwater Standards in samples collected from one or more downgradient MSW monitoring wells during the November 2019 monitoring event. As presented, a verification re -sampling event was conducted in January 2020 to verify an anomalous concentration of benzene observed in monitoring well MW-15R during the November 2019 sampling event. The results of the verification re -sampling of MW-15R did not confirm the anomalous concentration; however, benzene was also detected above the NC 2L Groundwater Standard during the verification sampling event.

One organic constituent (1,4-dioxane) was detected at quantifiable concentration above the surface water standard in samples collected from SW-1, SW-3, and SW-4 during the November 2019 monitoring event; this GOLDER February 21, 2020 Project No. 19127453 constituent was analyzed per the May 30, 2018, memorandum and is not part of the facility permit -required testing. 4.4 Alternate Source for Arsenic Based on previously collected data for this site, arsenic appears to be naturally occurring. The site -specific soil data presented in the Second Semi -Annual 2016 Water Quality Monitoring Report indicate that concentrations detected in naturally occurring soils on site can account for those measured in groundwater samples. Therefore, data support that above -standard concentrations of arsenic are naturally occurring. 4.5 Monitored Natural Attenuation Evaluation As presented as part of the corrective action program for the closed MSW landfill, additional "performance" or MNA parameters are collected to document natural attention. A summary of the "performance" or MNA parameters is included in this report as Table 8. Following each second semi-annual water quality monitoring event, a series of select monitoring wells disseminating from the highest historical VOC concentrations (i.e., MW-6, MW-15) towards the hydraulic discharge feature (i.e., Horse Creek) are used to evaluate the natural attenuation process. The select groundwater monitoring wells include MW-4, MW-6, MW-11SR, and MW-15R. These monitoring wells were selected because of their location relative to each other and the groundwater plume. As presented, the monitoring wells are situated along a relatively straight line parallel to groundwater flow (see Drawing 1) and follow a path from the highest historical concentrations of VOCs towards the hydraulic discharge feature. These select monitoring wells also correlate with the study performed by HDR in the Water Quality Monitoring Plan (2006). The November 2019 analytical results for these select monitoring wells were evaluated using the Environmental Protection Agency (EPA)'s natural attenuation screening protocol (1999). To assist in the screening process the MNA results were first incorporated into Table 9 which acts as a summary of the results and provides a basic qualitative evaluation of the potential for biological degradation (or attenuation) of VOCs. The assimilated data was then processed quantitatively using the EPA's natural attenuation screening protocol worksheets. Based on the EPA's screening protocol worksheets, monitoring wells MW-6, MW-11 SR, and MW-15R received scores greater than 20, which indicates strong evidence for anaerobic biodegradation of VOCs. Monitoring well MW-4 received a score of 11, which indicates limited evidence for anaerobic biodegradation of VOCs (EPA, 1999). The EPA natural attenuation screening protocol worksheets are included as Figures 1— 4. Based on the results of the screening protocol, there is strong evidence that natural attenuation is occurring at the site. Since there is strong evidence that natural attenuation is occurring via the biodegradation of VOCs, the EPA's BIOCHLOR modeling software was used to simulate remediation by natural attenuation at the site. Current and historical results from monitoring wells MW-4, MW-6, MW-11 SR, and MW-15R were input into the modeling software. Modeling parameters for advection, dispersion, and the plume area were also input. The modeling parameters for advection, dispersion, and the plume area were determined to be the same as previous models performed for the site, allowing a direct comparison to previous results. A 50-year simulation period was selected for the model, representing the time at which waste was first placed in the landfill (the original source). The November 2019 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 (PCE), trichloroethene (TCE), GOLDER 10 February 21, 2020 Project No. 19127453 dichloroethene (DCE), and vinyl chloride (VC) over time with no degradation to concentrations where sequential 1 st order decay is occurring. The centerline plots can be used to forecast the contaminant plume size over time. A summary of the results of the BIOCHLOR model are provided on Figure 5. Because PCE and TCE were not detected in samples from downgradient monitoring wells MW-4, MW-6, MW-11SR, and MW-15R during the November 2019 monitoring event, the BIOCHLOR model could not be calibrated; however, the absence of PCE and TCE in these downgradient samples could be considered evidence of biodegradation. The concentration of DCE in the samples from MW-4, MW-6, MW-11SR, and MW-15R plots on or below the 1st order sequential decay curve. In both samples, the cis-1,2-DCE variety was the prominent form of DCE indicating that the detections represent daughter products of TCE. The centerline plot for VC shows concentrations in samples from MW-6, MW-11S, and MW-15 plot below the 1st order sequential decay curve. 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 of VOCs will continue. According to the current data, the plume size has stabilized, as indicated by the BIOCHLOR model. There is evidence that more aerobic conditions exist in the monitoring well furthest from the contaminant plume (MW-4). Aerobic conditions in the furthest downgradient well are not likely to impact natural attenuation at the site as DCE and VC both degrade co - metabolically and can be directly oxidized to carbon dioxide under aerobic conditions (EPA, 2000). Currently, the three primary constituents -of -concern (COCs) at the site are benzene, 1,4-dichlorobenzene (1,4- DCB), and VC. An iso-concentration map for each current COC has been included in this report as Drawing 2. The COC 1,4-DCB was not detected above the NC 2L Groundwater Standard in groundwater at the site during the November 2019 sampling event. Both benzene and VC typically degraded faster under the proper aerobic conditions; however, both will degrade anaerobically if the right conditions exist. A review of the historical concentrations of both benzene and VC show that concentrations of both COCs have decreased over time. 5.0 CONCLUSIONS In general, VOC concentrations in groundwater at the site are declining and the number of constituents with detected concentrations above the applicable groundwater standards in the downgradient monitoring network are decreasing. As presented and based on the results summarized herein, Moore County plans to petition the SWS to return to a Detection Monitoring Program [15A NCAC 13B .0545(b)(9)] at the active C&D landfill through the submittal of an ASD addendum. It is the County's belief that impacts observed in groundwater at the site originate from the upgradient closed MSW landfill which is currently in corrective action. The changes included in the recent Water Quality Monitoring Plan (Golder, 2019) and approved by NC DEQ in a communication dated January 2, 2020, will be incorporated into the next monitoring event (tentatively scheduled for April 2020). Based on the declining COC concentrations in groundwater, the County plans to continue with MNA unless an increase in VOC concentrations is observed or directed to proceed to an alternate groundwater remedy (i.e., Phase II) by NC DEQ.

Unless otherwise noted in an attached project narrative, all samples were received in acceptable condition and processed in accordance with the referenced methods/procedures. Results for these procedures apply only to the samples as submitted. The analytical results contained in this report are in compliance with NELAC standards, except as noted in the project narrative if applicable. This report shall not be reproduced except in full, without the written approval of the Laboratory. This report contains only those analyses performed by Environmental Conservation Laboratories. Unless otherwise noted, all analyses were performed at ENCO Cary. Data from outside organizations will be reported under separate cover. If you have any questions or require further information, please do not hesitate to contact me. Sincerely, Stephanie Franz For Meghan K Shea 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 56 PROJECT NARRATIVE Date: 13 December 2019 Client: Golder Associates, Inc. (G0007) Project: Moore Co LF Lab ID: CC18640, CC19666 Overview (� �Eo www.encolabs.com Environmental Conservation Laboratories, Inc. (ENCO) analyzed all submitted samples in accordance with the methods referenced in the laboratory report. Any particular difficulties encountered during sample handling by ENCO are discussed in the QC Remarks section below. Quality Control Samples The spike recovery of 1,4-Dioxane was outside of control limits for the 8260D SIM MS and MSD samples. The QC batch was approved based on acceptable LCS recovery of this analyte. The 8260D Continuing Calibration Verification sample (CCV) exhibited a high bias for 1,1,1-Trichloroethane, 1,1-Dichloroethane, Acetone, Acrylonitrile, Benzene, Bromochloromethane, Carbon Disulfide, Carbon Tetrachloride, Chloroform, Chloromethane, cis- 1,2-Dichloroethene, lodomethane, trans- 1,2-Dichloroethene, Trichloroethene, Trichlorofluoromethane, Vinyl Chloride, and Tetrahydrofuran. The LCS sample also exhibited a high bias for Bromochloromethane. However, these analytes were not detected in the associated samples, reducing the impact of the deviation. The spike recovery of Iron was outside of control limits for the 601 OD MS, MSD, and Post Spike samples. The QC batch was approved based on acceptable LCS recovery of this element. The spike recoveries of Alkalinity, Chloride, Sulfate, and Sulfide were outside of control limits for the MS or 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 project arrived in acceptable conditions. The samples were not checked for residual chlorine, as it is not required. The analytical data presented in this report are consistent with the methods as referenced in the analytical report. Any exceptions or deviations are noted in the QC remarks section of this narrative or in the Flags/Notes and Definitions section of the report.

I Page 51 of 56 (� �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. QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there is no impact.

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 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. NTT 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. y Antimony: 2x in MW-13D, MW-13S, MW-11 DR, MW-17D and Field Blank Thallium: 2x in MW-13D, MW-13S, MW-11 DR, MW-17D and Field Blank ➢ Alkalinity 2x in MW-11 DR NTT The report provides the reporting limit for each constituent.

Any particular difficulties encountered during sample handling by ENCO are discussed in the QC Remarks section below. Quality Control Samples The spike recovery of 1,4-Dioxane was outside of control limits for the 8260D SIM ID MS and MSD samples. The QC batch was approved based on acceptable LCS recovery of this analyte. The spike recovery of Trichloroethene was outside of control limits for the 8260D LCS sample, indicating a possible high bias; however, this analyte was not detected in the associated sample, reducing the impact of the deviation. The Continuing Calibration Verification sample (CCV) exhibited a high bias for 1,1-Dichloroethene, Carbon disulfide, and Trichlorofluoromethane; however, these analytes were not detected in the associated samples. Precision between duplicate analyses of Methane exceeded acceptance criteria for the RSK-175 analysis. The QC batch was approved based on acceptable LCS recovery of this analyte. The spike recoveries of Iron and Mercury were outside of control limits for the MS, MSD, and/or Post spike samples. The QC batches were approved based on acceptable LCS recovery of these elements. The spike recoveries of Alkalinity, Chloride, Nitrate/Nitrite (NOx), Nitrite, Sulfate, Sulfide, and TOC were outside of control limits for the MS and/or MSD samples, and precision between duplicate TDS analyses exceeded acceptance criteria. 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 residual chlorine, as it is not required. The analytical data presented in this report are consistent with the methods as referenced in the analytical report.

I Page 81 Of 92 (� �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-02 The RPD and/or percent recovery for this QC spike sample cannot be accurately calculated due to the high concentration of analyte present in the sample. 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. 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.

The spike recovery of Trichloroethene was outside of control limits for the 8260D LCS sample, indicating a possible high bias; however, this analyte was not detected in the associated sample, reducing the impact of the deviation. The Continuing Calibration Verification sample (CCV) exhibited a high bias for 1,1-Dichloroethene, Carbon disulfide, and Trichlorofluoromethane; however, these analytes were not detected in the associated samples. Precision between duplicate analyses of Methane exceeded acceptance criteria for the RSK- 175 analysis. The QC batch was approved based on acceptable LCS recovery of this analyte. j- The spike recoveries of Iron and Mercury were outside of control limits for the MS, MSD, OLDER ASSOCIATES NC, INC.

Notes: 5.0 DATA REPORTING NTT All analytical reporting associated with the event was performed by the contracted lab NTT 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. NTT 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 1 Ox 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. ➢ Total Alkalinity as CaCO3: 2x in MW-2, MW-14, & MW-6 ➢ Total Alkalinity as CaCO3: 5x in MW-11SR ➢ Total Alkalinity as CaCO3: 10x in MW-9 ➢ Thallium: 2x in MW-4, MW-5, MW-11SR, MW-14, & MW-17S ➢ Antimony: 2x in MW-4, MW-5, MW-11SR, MW-14, & MW-17S ➢ Methane: 10x in MW-6, MW-9, MW-14, & MW-15SR ➢ Sulfate as SO4: 2x in MW-17S ➢ Nitrate: 5x in MW-4 ➢ Methane: 5x in MW-7 ➢ Chloride: 2x in MW-9 NTT The report provides the reporting limit for each constituent.

I Page 6 Of 8 (� �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.

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. NTT 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. NTT The report provides the reporting limit for each constituent. NTT The results were reported at or below their proper reporting limits. Those that are not reported correctly are listed below (by constituent) with the proper reporting limit listed beside them.
