(Golder) is submitting the enclosed Water Quality Monitoring Report (Report), which documents the results of the November 27 - 29, 2018, assessment and corrective action water quality monitoring event, and the February 13, 2019, verification event, at the Moore County Landfill located in Aberdeen, North Carolina. The November 2018 water quality monitoring event was the second 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 2018 event were analyzed for Appendix I constituents plus previously detected Appendix II constituents (naphthalene) 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 tetra hydrofu ran]. During the November 2018 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-16S 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. During the November 2018 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 also sampled and analyzed for Appendix I VOCs 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. As presented, four inorganic constituents (cobalt, iron, manganese, and vanadium) were detected at concentrations that exceed their respective NC 2L Groundwater Standards in samples collected from one or more downgradient C&D monitoring wells during the November 2018 water quality monitoring event. Cobalt and vanadium concentrations are estimated below their respective practical quantitation limits (PQLs). Concentrations are generally similar to historical data. Two Appendix I VOCs (benzene and vinyl chloride) were detected in samples from one or more downgradient monitoring wells at concentrations that exceed their respective NC 2L Groundwater Standards during this event. Additionally, 1,4-dioxane was detected at concentrations above the PQL and NC 2L 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. One Appendix II VOC (naphthalene) was detected at a concentration below the NC 2L Groundwater Standard in samples from monitoring wells MW-11SR and MW-14. Naphthalene was added as a detected Appendix II constituent for monitoring wells MW-11 SR and MW-14 per the approved Assessment Monitoring Work Plan. 4 GOLDER March 27, 2019 0739615018 As presented, one 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 2018 water quality monitoring event. Two NC Appendix I organic constituents (benzene 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 PQL and NC 2L 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. As presented, four surface water monitoring points were sampled during the November 2018 monitoring event. One organic constituent (1,4-dioxane) was detected at quantifiable concentration above the surface water standard in samples collected from SW-3 during the November 2018 monitoring event. Additionally, one organic constituent (toluene) was detected at an estimated concentration in samples from SW-4 during the November 2018 monitoring event. On February 13, 2019, Golder conducted a verification sampling event for SW-3 and SW-4; verification results confirmed the original 1,4-dioxane concentrations at SW-3 but not the toluene concentration at SW-4. Based on the results of the November 2018 water quality monitoring event, Moore County plans to continue monitoring groundwater and surface water at the facility in accordance with the approved Assessment Monitoring Work Plan at the active C&D landfill and the approved Water Quality Monitoring Plan at the closed MSW landfill. 4 GOLDER March 27, 2019 0739615018 Table of Contents 1.0 INTRODUCTION.............................................................................................................................................1 1.1 Site Description and Background.........................................................................................................1 1.2 Compliance Monitoring History............................................................................................................1 1.3 Hydrogeologic Setting..........................................................................................................................4 2.0 FIELD PROGRAM, MONITORING RESULTS, AND DISCUSSION.............................................................4 2.1 Visual Inspection Program...................................................................................................................5 2.2 Monitoring Well Network and Groundwater Elevation Measurements................................................5 2.3 November 2018 Water Quality Monitoring Event.................................................................................5 2.4 Laboratory Analysis Program...............................................................................................................6 2.5 February 2019 Verification Event.........................................................................................................7 3.0 LABORATORY AND FIELD QA/QC..............................................................................................................7 4.0 DATA EVALUATION......................................................................................................................................7 4.1 NC Groundwater Quality Standard Comparisons — C&D Landfill........................................................7 4.2 NC Groundwater Quality Standard Comparisons — MSW Landfill.......................................................8 4.3 NC Surface Water Quality Comparisons — C&D & MSW Landfills......................................................9 4.4 Alternate Source for Arsenic................................................................................................................9 4.5 Monitored Natural Attenuation Evaluation...........................................................................................9 5.0 CONCLUSIONS............................................................................................................................................10 6.0 REFERENCES..............................................................................................................................................10 TABLES TABLE 1 — SUMMARY OF HISTORICAL GROUNDWATER ELEVATION DATA TABLE 2 — SUMMARY OF ESTIMATED HORIZONTAL FLOW VELOCITIES TABLE 3 — SUMMARY OF WELL CONSTRUCTION INFORMATION TABLE 4 — SUMMARY OF HISTORICAL GROUNDWATER MONITORING RESULTS TABLE 5 — SUMMARY OF HISTORICAL GROUNDWATER FIELD PARAMETERS TABLE 6 — SUMMARY OF HISTORICAL SURFACE WATER MONITORING RESLTS TABLE 7 — SUMMARY OF HISTORICAL SURFACE WATER FIELD PARAMETERS TABLE 8 — SUMMARY OF MONITORED NATURAL ATTENUATION PARAMETERS GOLDER iv March 27. 2019 DRAWINGS GROUNDWATER SURFACE CONTOUR MAP (NOVEMBER 27, 2018) RECENT VOC NC 2L GROUNDWATER EXCEEDANCES (NOVEMBER 2018) APPENDICES APPENDIX A GROUNDWATER AND SURFACE WATER SAMPLING LOGS [1$Li!ll-19 1K APPENDIX B NOVEMBER 2018 AND FEBRUARY 2019 GROUNDWATER AND SURFACE WATER CERTIFICATE -OF - ANALYSIS, CHAIN -OF -CUSTODY FORMS AND LABORATORY DATA REVIEW GOLDER March 27, 2019 0739615018 1.0 INTRODUCTION This report summarizes the monitoring results from the first semi-annual 2018 water quality monitoring event at the Moore County Landfill conducted November 27 - 29, 2018, and the February 13, 2019, verification event. 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 maintained by Moore County (the County) under 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 in the 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. Access to the site is 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. The Moore County Landfill comprises approximately 314 acres and contains a closed, unlined MSW unit, an active C&D 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 area encompasses approximately 60 acres, 12 of which have a clay cap. The County began transferring MSW waste in 1993. The County temporarily stockpiled C&D waste from approximately 1993 to 1996, until the current 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 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) which were detected in groundwater samples and methane gas. Concerns of off -site migration 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 monitoring network in 1996, along with upstream and downstream surface water monitoring points (SW-2 and SW-1). 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 include MW-11S/D, MW-12S/D, MW-13S/D, and MW-14. Monitoring well 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-11 S/D, MW-12S/D, and 4 GOLDER March 27, 2019 0739615018 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 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 trenching and venting network consisting of a trench and 12 passive LFG vents were installed to address LFG concerns; this network was expanded via 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 will 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 is required to submit another CAER (after the 2016 sampling events). In order to better assess surface water quality and potential offsite plume migration at the site 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 unlined 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 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. 4 GOLDER March 27, 2019 0739615018 Following the November 30, 2017 meeting with NC DEQ, the County submitted a 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 tetra hydrofu ran. 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. During the November 2018 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 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 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-11SR, MW-14, and MW-16S 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. Upon completion of the fourth background sampling event (i.e., second semi-annual sampling event in 2019), 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 (NC 2L IMAC Standards). In the case of metals, comparisons will also be made to background concentrations, as appropriate. Pending the results of 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 4 GOLDER March 27, 2019 0739615018 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. 1.3 Hydrogeologic Setting The facility is located in the inner Coastal Plain Physiographic Province of North Carolina. 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 2018 monitoring event are summarized in Table 1 and were used to prepare a 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 27, 2018, 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 5.59E-3 centimeters per second (cm/s), which is the average of the hydraulic conductivities calculated from slug tests from 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: Kxi Vgw n e where Vg,N = 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 301 feet/year, which is consistent with previous estimates (Table 2). 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. 2.0 FIELD PROGRAM, MONITORING RESULTS, AND DISCUSSION Field activities conducted for the November 2018 sampling event are discussed in the following sections. 4 GOLDER March 27, 2019 0739615018 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 2018 compliance monitoring event, no physical indicators of a potential release were observed in the vicinity of the waste management areas by the sampling personnel. 2.2 Monitoring Well Network and Groundwater Elevation Measurements As presented, there are two 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-11DR, MW-13S, MW-13D, MW-16S, and MW-16D) 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-11S, MW-14, and MW-16S) are also used as "performance" or "MNA" monitoring wells to assess groundwater impacts from the MSW landfill. Available monitoring well construction information for all site monitoring wells is summarized on Table 3 and the well locations are shown on Drawing 1 The 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. 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 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 upgradient/sidegradient background monitoring well MW-5. The range in fluctuation in the downgradient compliance wells varies depending on their location, relative to the hydraulic discharge boundary. 2.3 November 2018 Water Quality Monitoring Event Personnel from Golder visited the facility from November 27 - 29, 2018, to purge and sample the seventeen (17) groundwater monitoring wells; to sample the four (4) surface water monitoring points; and to sample the Blake residence water well 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 4 GOLDER March 27, 2019 0739615018 approximately 2 to 5-minute intervals, depending on the purge rate. In general, the purge rate for each well was matched to the yield of the monitoring well, as determined by continuously monitoring the depth to the water, up to a maximum purge rate of 300 milliliters per minute. Purging was continued 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. The groundwater sampling logs are presented in Appendix A. Included in each log is a description of the sampling equipment, method, location, field observations, and water quality measurements. 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 control. The surface water sampling logs are presented in Appendix A. Included in each log is a description of the sampling equipment, method, location, field observations, and water quality measurements. 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. 2.4 Laboratory Analysis Program The November 2018 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 2018 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-16S 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 Department of Environmental Quality (DEQ). Per the laboratory receipt summaries, which can be 4 GOLDER March 27, 2019 0739615018 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 February 2019 Verification Event Golder personnel visited the facility on February 13, 2019, to resample SW-3 and SW-4 to verify VOC concentrations observed during the November 2018 event. Samples were collected utilizing techniques as those described above. After collection, the samples were placed in a cooler on ice, under chain -of -custody control. A copy of the sampling logs are included in Appendix A. Included on the logs is a description of the sampling equipment, sampling method, field observations, location, and water quality measurements. 3.0 LABORATORY AND FIELD QA/QC A field blank was collected by Golder personnel as part of the November 2018 groundwater and surface water sampling event. In addition to the field blank, a laboratory -prepared trip blank accompanied the volatile sample containers for the November 2018 sampling event and February 2019 verification event to and from the laboratory. ENCO analyzed the field blank for Appendix I VOCs plus Detects and RCRA metals, and the trip blank for Appendix I VOCs. Reviews of the laboratory data were performed by Golder personnel and are included in Appendix B. Based on Golder's review of the laboratory results copper was detected in one or more of the blanks during the November 2018 sampling event at an estimated concentration. Based on the review of laboratory information by Golder personnel, none of the samples collected during the November 2018 event were blank qualified. 4.0 DATA EVALUATION The results of the data evaluations are presented in the following sections. 4.1 NC Groundwater Quality Standard Comparisons — C&D Landfill As presented in Table 4, four inorganic constituents (cobalt, iron, manganese, and vanadium) were detected at concentrations that exceed their respective NC 2L Groundwater Standards in samples collected from one or more downgradient C&D monitoring wells during the November 2018 water quality monitoring event. The following is a summary of the inorganic NC 2L Groundwater Standard or Interim Maximum Allowable Concentration (IMAC) exceedances during the November 2018 sampling event in the active C&D landfill groundwater monitoring network: Cobalt NC 2L or IMAC 1.0 ug/L (IMAC) NC 2L Groundwater ..

Denotes estimated concentration below the PQL 4 GOLDER March 27, 2019 0739615018 Cobalt and vanadium were detected at estimated concentrations above the IMAC standard but below the PQLs in all the samples presented above as exceedances. Per 15A NCAC 02L .0202 (b)(1), "where the standard for a substance is less than the practical quantitation limit (PQL or MRL), the detection of that substance at or above the PQL constitutes a violation of the standard." As referenced, the cobalt and vanadium concentrations detected during the November 2018 sampling event do not constitute violations of the IMAC standards. Two organic constituents (benzene and vinyl chloride) listed in Appendix I of 40 CFR 258, 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.

The following is a summary of the inorganic NC 2L Groundwater Standard or IMAC exceedances during the November 2018 sampling event in the closed MSW landfill groundwater monitoring network: Two organic constituents (benzene and vinyl chloride) listed in Appendix I of 40 CFR 258, 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 this monitoring event.

One organic constituent (1,4-dioxane) was detected at quantifiable concentration above the surface water standard in samples collected from SW-3 during the November 2018 monitoring event; this constituent was analyzed per the May 30, 2018, memorandum and is not part of the facility permit -required testing. Additionally, one organic constituent (toluene) was detected at an estimated concentration in samples from SW-4 during the November 2018 monitoring event. On February 13, 2019, Golder conducted a verification sampling event to assess the VOC concentrations in SW-3 and SW 4. The results of the resampling event confirmed the detection of 1,4-dioxane in SW-3 but not toluene at SW-4. 4.4 Alternate Source for Arsenic Arsenic appears to be naturally occurring based on previously collected data for this site. 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. A 9; Monitored Natural Attenuation Evaluation A series of monitoring wells within the constituent -of -concern VOC plumes shown on Drawing 2 were selected for a performance evaluation of MNA processes. Monitoring wells MW-4, MW-6, MW-11SR, and MW-15R were selected since they form a relatively straight line, are situated approximately parallel to groundwater flow (Drawing 1), and correlate with the study performed by HDR in the Water Quality Monitoring Plan (2006). The November 2018 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 and MW-11 SR received scores greater than 20, which indicates strong evidence for anaerobic biodegradation of chlorinated organics (EPA, 1999). Monitoring well MW-15R received a score of 19, which indicates adequate evidence for anaerobic biodegradation of chlorinated organics (EPA, 1999). Monitoring well MW 4 received a score of 10, which indicates there is limited evidence for anaerobic biodegradation of chlorinated organics. The MNA evaluation worksheets and natural attenuation screening protocol forms are included in Appendix E. Based on the results of the screening protocol, there is evidence that natural attenuation is occurring at the site; therefore, modeling was performed on the November 2018 data to simulate remediation by natural attenuation using a screening model called BIOCHLOR (EPA, 2000). Monitoring wells MW-4, MW-6, MW-11SR, and MW-15R were used in the model. Modeling parameters for advection, dispersion, and modeled area were the same as previous models performed for the site, so that model results could be compared. 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 2018 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), dichloroethene (DCE), and vinyl chloride (VC) over time with no degradation to concentrations where sequential 1st order decay is occurring. The plots are provided in Appendix E. The centerline plots can be used to forecast the contaminant plume size over time. 4 GOLDER March 27, 2019 0739615018 Because PCE and TCE were not detected in samples from downgradient monitoring wells MW-4, MW-6, MW-11 S, and MW-15 during the November 2018 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-11S, and MW-15 plots on or below the 1 st 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 will likely continue. According to the current data, it is 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). These more aerobic conditions in the furthest downgradient well will not likely impact the MNA at the site as VC and possibly DCE can both degrade co -metabolically and can be directly oxidized to carbon dioxide under aerobic conditions (EPA, 2000). 5.0 CONCLUSIONS As presented and based on the results summarized herein, Moore County Landfill will monitor the uppermost aquifer beneath the active C&D landfill in accordance with the approved Assessment Monitoring Work Plan. 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, following the completion of the second semiannual water quality monitoring event at the C&D landfill in 2019, 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 County will also continue to monitor the upper most aquifer beneath the MSW landfill in accordance with the approved Water Quality Monitoring Plan (HDR, July 2006) and the approved Groundwater Corrective Action Milestone Schedule. Following the completion of the second semiannual water quality monitoring event at the MSW landfill in 2019 (and prior to December 31, 2019), the County plans to submit a corrective action evaluation report in accordance with the approved Groundwater Corrective Action Milestone Schedule to evaluate the Phase I remedy. 6.0 REFERENCES Golder Associates NC, Inc.

(G0007) Project: Moore Co LF Lab ID: C1317731, CB18520, CB18713 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 recoveries of 1, 1 -Dichloroethene, Benzene, Chlorobenzene, Toluene and Trichloroethene were outside of control limits, and precision between duplicate spikes exceeded acceptance criteria. The QC batches were approved based on acceptable LCS recovery of these analytes. The LCS sample exhibited a high bias for Trichloroethene; however, this analyte was not detected in the associated samples. LCS/LCSD were analyzed in place of MS/MSD for the 8260C SIM analysis for 1,4-Dixoane. The spike recoveries of Iron, Mercury, and Silver were outside of control limits for the 601 OD (7470 for Mercury) MS, MSD, and/or Post Spike samples. The QC batch was approved based on acceptable LCS recovery of these elements. The spike recovery of Sulfide was outside of control limits for the MS sample,. The QC batch was approved based on acceptable LCS recovery of this analyte. Quality Control Remarks No comments Other Comments All samples received under this 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 56 Of 63 (� �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. 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-10 LCS/LCSD were analyzed in place of MS/MSD. QM-12 Precision between duplicate samples was outside acceptance limits. QR-05 The RPD value for the sample duplicate or MS/MSD was outside of QC acceptance limits. QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there is no impact.

Proper EPA SW-846 analytical methods were used for analysis. DATA REPORTING BD All analytical reporting associated with the event was performed by the contracted lab BD 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 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. Field Blank: Copper @ 2.26 (J) ug/L BD It is clear from the laboratory report that samples have or have not been diluted during analysis, and if the samples have been diluted, the result is reported as a multiple of the dilution (e.g., a sample diluted 10x resulting in an analytical detection of 1.0 should be reported as 10). Those that have been diluted are listed below with the dilution factor. Antimony and Thallium (5X): MIN-13S, MIN-11DR, MIN-13D, MIN-16D, Field Blank BD The report provides the reporting limit for each constituent.

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. QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable LCS recovery.

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. ➢ Field Blank: Copper @ 2.26 (J) ug/L TM It is clear from the laboratory report that samples have or have not been diluted during analysis, and if the samples have been diluted, the result is reported as a multiple of the dilution (e.g., a sample diluted 10x resulting in an analytical detection of 1.0 should be reported as 10). Those that have been diluted are listed below with the dilution factor. ➢ Mercury x 1.25 TM The report provides the reporting limit for each constituent. TM 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. State if the reporting limit error is due to dilutions. TM No inorganic or organic constituents were reported above their respective NC 2L Drinking Water Standards or IMAC standards in wells, surface points, or field/equipment/trip blanks. ➢ Lead (NC 2L = 15 uq/L) • Blake Res @ 23.7 uh/L TM No quantifiable inorganic or organic constituents were detected in a well or surface water point at concentrations outside of their historical range (more than 5X previous concentrations or first-time detections).

(G0007) Project: Moore County LF Lab ID: C1317733, CB18519, CB18712 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 recoveries of 1, 1 -Dichloroethene, Benzene, Chlorobenzene, Toluene and Trichloroethene were outside of control limits, and precision between duplicate spikes exceeded acceptance criteria. The QC batches were approved based on acceptable LCS recovery of these analytes. The LCS sample exhibited a high bias for Trichloroethene; however, this analyte was not detected in the associated samples. LCS/LCSD were analyzed in place of MS/MSD for the 8260C SIM analysis for 1,4-Dixoane. The spike recoveries of Iron, Mercury, and Silver were outside of control limits for the 601 OD (7470 for Mercury) MS, MSD, and/or Post Spike samples. The QC batch was approved based on acceptable LCS recovery of these elements. The spike recoveries of Nitrite, Nitrate/Nitrite (NOx), Sulfide, and TOC were outside of control limits for the MS and/or MSD samples, and precision between duplicate analyses of Sulfide and TDS exceeded acceptance criteria. The QC batches were approved based on acceptable LCS recovery of these analytes. Quality Control Remarks The 8260C SIM internal standard exceeded acceptance criteria for MW-2. The reported result should be considered estimated. 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 77 Of 87 (� �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. QI-02 Internal standard outside acceptance limits. Samples results are considered estimated. 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-10 LCS/LCSD were analyzed in place of MS/MSD. QM-12 Precision between duplicate samples was outside acceptance limits. QR-05 The RPD value for the sample duplicate or MS/MSD was outside of QC acceptance limits. QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there is no impact.
