(S&ME) for the Moore County Landfill, North Carolina Solid Waste Permit No. 61-03. This CAER was prepared in accordance with the guidance document "Guidelines for Corrective Action Evaluation Reports" issued by the NC Department of Environmental Quality (NCDEQ) formerly known as the North Carolina Department of Environment and Natural Resources. 1.1 Site Description and Background The Moore County Landfill (the "facility") is located at 456 Turning Leaf Way in Aberdeen, North Carolina as shown on Figure 1. The facility is owned and operated by Moore County under Solid Waste Permit No. 63-01 issued by the NCDEQ-SWS. The facility encompasses approximately 314 acres and contains a municipal solid waste (MSW) transfer facility, a closed unlined MSW landfill and an active C&D landfill. The closed unlined MSW Landfill is located on the eastern side of the facility (comprising approximately 60 acres) and the active Construction and Demolition (C&D) Landfill is located on the western side of the facility. Several smaller Land Clearing and Inert Debris (LCID) landfill units are also present at the facility. The facility is bound to the west by Horse Creek and to the north and south by unnamed tributaries of Horse Creek. A power -line right-of-way transects the property and represents the eastern boundary of the closed MSW landfill. 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 on the southwestern side of the facility. The site is surrounded by wooded, agricultural, or rural residential properties. The Moore County MSW landfill began accepting solid waste in 1968 and stopped accepting waste before October 9, 1993. The landfill was capped and closed to avoid Resource Conservation and Recovery Act (RCRA) Subtitle D regulations under the NCAC 1313.1600 rules. The final closure was approved by NCDEQ in December 1996 and the County expressed their intent to comply with post -closure monitoring regulations in January 1997. In 1993, a transfer station was constructed at the facility to handle the County's solid waste stream. In September of 1993, Moore County entered into an agreement with Uwharrie Environmental, Inc. which later became Republic Services of North Carolina, LLC, granting the private company operation responsibilities at its transfer station. After closure of the MSW landfill in 1993, the County opened a C&D landfill under the existing solid waste permit #63-01. The County temporarily stockpiled C&D waste from approximately 1993 to 1996, until the current landfill C&D landfill was permitted and constructed. The County manages the C&D and LCID waste streams generated within Moore County and operates the C&D landfill. S&ME understands that at the request of the NCDEQ, the facility voluntarily commenced a corrective action program, specifically Monitored Natural Attenuation (MNA), due to groundwater impacts from volatile organic compounds (VOCs) at the closed unlined MSW landfill. The County also monitors water quality at the active C&D landfill in accordance with Title 15A of the North Carolina Administrative Code (NCAC) 1313. 0600 and the facility's approved modified Water Quality Monitoring Plan (WQMP). June 15, 2023 Corrective Actions Evaluation Report Moore County Landfill �r Aberdeen, North Carolina S&ME Project No. 4358-20-043D I 1.2 Compliance Monitoring History The MSW landfill was originally monitored by five monitoring wells which were installed in June 1987. The original MSW landfill monitoring network consisted of MW-1, MW-2, MW-3, MW-4, and MW-5. Monitoring wells MW-1, MW-2, MW-3, and MW-4 were used as the downgradient monitoring wells and MW-5 (side gradient of the MSW landfill) was used as the background well. The five original monitoring wells were located with the anticipation of expanding the MSW landfill; however, prior to the promulgation of the Subtitle D regulations, the County closed the MSW landfill. The County constructed the currently active C&D landfill to the west and down -gradient of the closed MSW landfill. Since the monitoring wells MW-3 and MW-4 are downgradient of the active C&D facility, monitoring wells MW-6 through MW-9 were added in March 1995 to monitor the area between the MSW and C&D facilities. Monitoring well MW-10 was also added to the monitoring network in March 1995 to monitor the groundwater down -gradient of the C&D landfill. Because the MSW landfill closed in October 1993, the County monitored the closed MSW landfill under the 15A NCAC 13B. 0600 Rules. Due to detections of VOCs in samples from monitoring wells downgradient of the closed MSW landfill and concerns of off -site migration expressed by the NCDEQ in January 1996, the County voluntarily proceeded with groundwater corrective action. In September 1996, additional monitoring wells were installed at the facility in an effort to delineate the horizontal and vertical extent of contamination, and to serve as monitoring points for the newly constructed C&D facility. The additional monitoring wells included MW-11S/D, MW-12S/D, MW-13S/D, MW-14, and MW-15. Monitoring wells MW-16S/D were later installed to replace MW-12S/D during an expansion of the C&D facility. A private water supply well at the Blake residence (PW-1), which is located upgradient of the facility, was added to the monitoring network in 1996, along with surface water monitoring points (SW-1 and SW-2). Following the approval of the CAER submitted in May 2012, two additional surface water monitoring points were added in order to better assess surface water quality and potential plume migration at the site. In October 2012, surface water points SW-3 and SW-4 were added to the compliance monitoring network and were sampled for the first time. In a letter dated October 6, 1999, the NCDEQ, in a response to low-level VOC detections and exceedances of methane above the lower explosive limit (LEL) along the northern property line, requested that the County perform a water quality assessment and explosive gas study in accordance with 15A NCAC 13B. 0402(3) to delineate the extent of VOC impacts to groundwater and the possibility of methane gas crossing the property line. A "Methane and Groundwater Quality Assessment Report" was submitted with an addendum to NCDEQ in December of 2000. In this report, HDR identified a confining unit at depth, which was reported to limit vertical groundwater contamination. In January 2005, NCDEQ 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 one or more of the following criteria were met: An increasing trend in contaminant concentrations was not originally predicted during remedy selection. Large increases in contaminant concentration in near -source wells are indicative of a new release. Identification of contaminants in monitoring wells located outside the original plume boundary. Evidence that contaminants may reach a receptor or other media (e.g., surface water) not previously expected to be reached. Contaminant concentrations are not decreasing rapidly enough to achieve the remediation objectives. Changes in surrounding land and/or groundwater which may adversely affect the protectiveness of MNA. June 15, 2023 Corrective Actions Evaluation Report Moore County Landfill Aberdeen, North Carolina S&ME Project No. 4358-20-043D ICI_ NCDEQ 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). A revised WQMP was prepared in July 2006 and approved October 13, 2006, by NCDEQ. 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 NCDEQ 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 would collect the full suite of "performance monitoring parameters" in April and October 2011, and present a MNA CAER after completion of the October 2011 water quality monitoring event (WQME). The first MNA CAER was submitted to the NCDEQ on May 15, 2012, and in a letter dated August 30, 2012, the NCDEQ 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). On May 16, 2013, Joyce Engineering, Inc. submitted Contingency Plan Update and Implementation Plan - Revised which was approved by NCDEQ June 5, 2013. Three passive gas vents (GV-30, GV-31, and GV-32) were installed in February 2014. As a follow up to the installation of the passive gas vents a Contingency Plan Update Evaluation was submitted by Golder on March 16, 2015. In the Contingency Plan Update Evaluation letter, the County requested more time to assess the effectiveness of the passive gas vents. A meeting was held on March 10, 2016, to discuss the groundwater trends at the site and the effectiveness of the passive gas vents. During this meeting, Golder indicated it appeared that groundwater VOC concentration trends over time were declining. At this meeting and in a correspondence dated March 14, 2016, NCDEQ indicated that an Alternate Source Demonstration (ASD) would be required to address groundwater impacts in the C&D landfill monitoring wells. Since the beginning of the 2005 ACM activities, it was inferred that the VOC impacts in groundwater samples from C&D monitoring wells were due to the MSW landfill, as impacts were noted during the initial sampling event at the C&D facility. In two letters dated September 28, 2017, the NCDEQ-SWS indicated that they would not approve the ASD for VOCs at the C&D Landfill, at that time. They also requested that Moore County implement landfill gas and groundwater corrective action at the closed MSW landfill; and commence assessment monitoring at the C&D landfill pursuant to 15A NCAC 13B .0545. On December 6, 2017, after additional communications and a meeting with NCDEQ-SWS, Moore County submitted a letter confirming their intention to comply with the NCDEQ-SWS requests and requested an extension to comply, which was approved by NCDEQ-SWS on December 11, 2017. On behalf of Moore County, Golder submitted: CAER dated October 16, 2017, Assessment Monitoring Work Plan, dated January 5, 2018. Landfill Gas Remediation Plan dated January 31, 2018, Groundwater Corrective Action Milestone Schedule, dated January 31, 2018 (which included the submission of the NC Solid Waste .0500 Groundwater Corrective Action Application), and In accordance with Golder's Assessment Monitoring Work Plan, dated January 5, 2018, monitoring wells MW-11 SR, MW-11 DR, and MW-15R were subsequently installed to replace monitoring wells MW-11 S, MW-11 D, and MW-15. The replacement wells were sampled in June 2018, as part of the first assessment monitoring event for the C&D June 15, 2023 Corrective Actions Evaluation Report Moore County Landfill .� Aberdeen, North Carolina S&ME Project No. 4358-20-043D landfill. Groundwater samples collected from assessment monitoring wells were analyzed for constituents listed in North Carolina Appendix II and the C&D landfill indicator parameters required by NCDEQ-SWS (e.g., chloride, manganese, sulfate, iron, alkalinity, total dissolved solids (TDS), and tetrahydrofuran). Samples from monitoring wells MW-6 and MW-7 were also analyzed for Appendix II constituents, to further assess whether the groundwater impacts detected at the C&D landfill were attributable to the upgradient MSW landfill. In a letter dated February 22, 2018, NCDEQ approved a request made by Moore County to decommission monitoring wells MW-16S and MW-16D and replace them in the groundwater monitoring network with MW-175, MW-17D, and MW-18 which were to be installed in conjunction with the permitting of new Cell VI of the C&D landfill. Between May 31 and June 4, 2018, monitoring wells MW-175, MW-17D, and MW-18 were installed, and monitoring wells MW-16S and MW-16D were properly abandoned. Monitoring wells MW-17S and MW-17D were first sampled during the routine semi-annual monitoring event conducted during November 2019. Monitoring well MW-18 was first sampled during the routine semi-annual monitoring event conducted in April 2020. During the April 2020 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 NCDEQ-SWS 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, 2078) Replacement of MW-15 with MW-15R (completed June 1, 2018) Conversion of MW-15 to compliance methane monitoring well GP-18 (completed December 7, 2018) Continuation of MNA (as detailed in the approved Water Quality Monitoring Plan) In accordance with the approved Water Quality Monitoring Plan, dated December 10, 2019, hereafter referred to as the WQMP, monitoring wells in the MSW compliance network are corrective action MNA monitoring wells and are currently analyzed for VOCs listed in North Carolina Appendix I, 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, active C&D monitoring wells MW-4, MW-5, and MW-11SR are also sampled as corrective action MNA monitoring wells and analyzed for the same suite of MNA parameters. Analytical results for the April 2020 water quality monitoring event detected benzene at a concentration of 1.6 pg/L in monitoring well MW-18. Based on this apparent exceedance of the corresponding 2L Standard, a verification sampling event was conducted on June 5, 2020, with laboratory analyses reporting 1.2 pg/L Benzene. Based on the verified exceedance of the 2L Standard for benzene, an update of the Assessment Monitoring Program was required. On June 26, 2020, new monitoring well MW-19 was installed down -gradient (in the direction of contaminant migration) of monitoring well MW-18, near the facility boundary. Monitoring well MW- 19 was first sampled during October 2020, then monitored semi-annually thereafter. To date, benzene has not been detected at monitoring well MW-19. The facility is currently performing Phase I corrective measures, which include NCDEQ approved LFG remedies and groundwater remedies. Phase I remedies included installation of the methane cut-off trench near GP-18 and continuation of MNA for groundwater. The methane cut-off trench installed in 2018 was to serve dual purposes. The trench targeted reduction of the LEL conditions observed at GP-18. The local increase in venting of LFG could June 15, 2023 4 Corrective Actions Evaluation Report Moore County Landfill .� Aberdeen, North Carolina S&ME Project No. 4358-20-043D theoretically improve groundwater quality in the vicinity of MW-15R, by increasing the transfer of VOCs in LFG to the atmosphere, rather than to underlying groundwater. On behalf of Moore County, S&ME conducted additional site investigations focused on advancing knowledge of existing site conditions. As presented in S&ME's Waste Extents and Soil Cover System Thickness Assessment Report, dated June 30, 2022, and Landfill Gas Vent Installation Report, dated June 30, 2022, facility engineering controls that hold a potential to reduce contaminant mass transfers from landfill waste to groundwater, were considered for their potential contributions to long-term management of groundwater quality. S&ME performed limited assessments of the MSW landfill cover soil thickness, cover system surface topography, and waste extents. The relevant assessment findings include: The MSW cover system soils were observed to consist of three or more feet of soil, likely locally derived, overlying historically placed solid waste. Generally speaking, the observed soil cover system thickness was reasonable for a landfill closed during the early 1990s. A review of MSW landfill topography using 2021 site LIDAR survey data identified various subtle topographic low areas, likely related to settlement of waste over time. Several topographic low areas correlated with areas of observed temporary water ponding. With this information, Moore County initiated placement and grading of clean fill soils in select low areas, with a goal of improving positive storm drainage off the cover system. Restoring positive surface drainage off the landfill is expected to lessen water infiltration into the MSW waste and generation of landfill gas. Engineering controls that lessen water infiltration into the waste should diminish contaminant mass transfers from waste to groundwater, thereby enhancing the performance of MNA. A Frequency Domain Electromagnetic (FDEM) survey was employed to assess the lateral extents of the MSW landfill. The survey results found the extents to be similar to those historically depicted. The FDEM survey did result in recognition of a natural earth partition between two MSW landfill waste units. Given the sandy nature of site soils, this partition could represent a dominant local conduit for landfill gases migrating out of the adjacent waste units, then migrating northward toward gas monitoring point GP-18, the non -compliant northern property boundary monitoring point. It was hypothesized that installation of gas vent wells within this presumed gas migration conduit should relieve subsurface gas pressures and lessen the northward migration of landfill gases. In accordance with the NCDEQ approved Work Plan, new passive gas vent wells GV-35 and GV-36 were installed on June 16, 2022, as part of a gas vent pilot test. Quarterly landfill gas monitoring to date has indicated that these two new vent wells yield among the highest methane gas readings recorded at the facility. The pilot test is on -going. The October 2022 monitoring event included collection of samples for certain MNA analyses required for the five- year review CAER report, to be submitted in 2023. It is noted that several monitoring wells were replaced during this CAER 5-year review period. To simplify discussion, monitoring wells that were replaced will be referred to herein by the current well name (i.e., MW-11 S = MW-11 SR, MW-11 D = MW-11 DR, MW-13S = MW-13SR, MW-13D = MW-13DR, MW-15 = MW-15R. 1.3 Regulatory Status As stated above, the Moore County MSW Landfill stopped accepting waste before October 9, 1993, and the landfill was capped and closed by October 9, 1994; therefore, the facility was monitored under the 15A NCAC 13B June 15, 2023 Corrective Actions Evaluation Report Moore County Landfill Aberdeen, North Carolina S&ME Project No. 4358-20-043D ICI_ .0500 rules. As described above in Section 1.2, the facility commenced a groundwater corrective action program, specifically MNA, due to groundwater impacts from VOCs at the closed MSW landfill. In a letter dated April 18, 2008, NCDEQ requested that Moore County complete a MNA CAER after completion of the October 2011 WQME. The first MNA CAER prepared by Golder was submitted to the NCDEQ on May 15, 2012, and in a letter dated August 30, 2012, the NCDEQ granted the County permission to continue MNA for another five-year period at the end of which the County was required to submit another CAER. The second MNA CAER dated October 16, 2017, was prepared by Golder. This MNA CAER covers water quality monitoring for the period December 2017 through October 2022. 1.4 Aquifer Characteristics The facility is located within the Inner Coastal Plain Physiographic Province of North Carolina. The geologic units of this region range in age from the Cretaceous Period to the Tertiary Period. Based on the North Carolina Geologic Survey (NCGS) geologic map of North Carolina, the facility 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, Norman, and James, 1991). Prior assessment reports for the facility describe the subsurface mainly as silty sand (SM), poorly sorted sand (SP), and well sorted sand (SW) inter -bedded with discontinuous silt (ML) and clay (CL) lenses as defined by the Unified Soil Classification System (USCS). The discontinuous silt and clay lenses varied in thickness from one inch to several feet in facility borings. The lateral extents of these fine-grained lenses were not defined. The boring logs for monitoring wells installed at the facility can be found in Appendix I. A summary of monitoring well construction information is presented in Table 1. The uppermost groundwater beneath the facility is a shallow, unconfined aquifer comprised of primarily of sands mixed with relatively thin silt and clay seams. Beneath the facility, the uppermost aquifer is approximately 55 feet thick and underlain by a clay confining layer (HDR, 2005). This water table aquifer is recharged by precipitation infiltration, primarily in upland areas, with shallow groundwater discharging to local streams. Groundwater levels vary seasonally, declining during the summer when atmospheric conditions favor evaporation and plants transpire large amounts of water, and rising during the winter when plants are generally dormant. The MSW and C&D landfill units are located in upland areas that generally slope downward to the south toward Horse Creek. The waste management units occupy upland aquifer recharge areas. Water percolating through daily cover soils or final cover soil system interacts with waste and generates leachate. Leachate will percolate downward until it reaches the water table aquifer. Once leachate containing contaminants of concern (COC) enter the aquifer, characteristics of their migration in the aquifer are primarily governed by hydraulic pressure gradients and preferred flow paths within the aquifer media. In general, surface water and groundwater at the facility flows to the west and southwest toward Horse Creek, which is located along the western property boundary, representing the most significant local hydraulic boundary. Relative to the MSW and C&D landfill units, a lesser component of groundwater flow is presumed to the north and south toward adjacent minor unnamed tributaries of Horse Creek. Groundwater occurs at depths varying from approximately 6 to 34 feet below ground surface across the facility. Measurements of groundwater elevations obtained during the October 2022 monitoring event are summarized in Table 2 and were used to prepare a groundwater surface contour map presented as Figure 2. June 15, 2023 Corrective Actions Evaluation Report Moore County Landfill Aberdeen, North Carolina S&ME Project No. 4358-20-043D I A review of groundwater elevations at well nests MW-11 SR/MW-11 DR and MW-1 3SR/MW-1 3DR indicated vertical pressure gradients that suggest a relatively low downward flow component at these well locations. No nested wells pairs exist at the Horse Creek margin; however, it is reasonable to assume that the uppermost aquifer would exhibit an upward pressure gradient at Horse Creek, the most significant local hydraulic boundary. In April 2005 during the ACM study conducted by HDR seventeen, (17) groundwater monitoring wells (MW-1, MW-2, MW-3, MW-4, MW-5, MW-6, MW-7, MW-8, MW-9, MW-11S/D, MW-13S/D, MW-14, MW-15, and MW- 16S/D) were chosen to estimate of hydraulic conductivity for the upper aquifer sediments at the facility. Falling and rising head tests were applied to calculate the hydraulic conductivity values for well screen intervals representing the uppermost aquifer at the facility. Relying upon the HDR data, groundwater velocities are calculated for each semi-annual water quality monitoring event. Historically, 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 Golder and S&ME groundwater elevation contour maps prepared during this 5-year CAER review period were generally consistent with those previously submitted by Golder and HDR. Using site data collected, estimates for rates of groundwater flow for the uppermost aquifer beneath the monitored portion of facility were calculated using the following modified Darcy equation: Vaw = Ki/ne where Vgw = average linear velocity (feet/year), K = hydraulic conductivity (feet/year), i = horizontal hydraulic gradient, and ne = effective porosity. Five generalized flow paths were examined to estimate linear groundwater flow velocities within areas containing constituents of concern in groundwater (see Figure 2). The calculated linear velocities for these flow paths exhibited a range of 15 to 385 feet/year, with an average linear velocity of 111 feet/year, as shown on Table 3. The estimated average linear velocity of 161 feet/year for Pathway 1 was utilized in the BIOCHLOR modeling discussed in Section 2.0. The linear velocity equation makes simplifying assumptions of a homogeneous and isotropic aquifer. The range of linear velocity values observed are indicative of heterogeneous conditions present in the uppermost aquifer at the facility. The heterogeneous and anisotropic conditions imposed by site geologic conditions, include but are not limited to the discontinuous, relatively thin silt and clay lenses. 1.5 Contaminant Distribution The main COCs in groundwater at the facility are VOCs. Although inorganic constituents have been detected in groundwater samples above published standards, they appear to be naturally occurring based on available data and as presented in prior routine compliance monitoring reports. Groundwater and surface water analytical results from semiannual monitoring events from December 2017 through October 2022 are summarized in Table 4 and Table 5, respectively, along with the historical data available for the facility. The laboratory certificates -of -analysis, the chain of custody form, and laboratory data reviews for these sampling events were provided previously with corresponding Water Quality Monitoring Reports. Multiple Appendix I organic constituents were detected above the method detection limit (MDL) in samples from one or more downgradient monitoring wells during this CAER review period. Three of the Appendix I organic constituents were detected at concentrations that exceeded their respective 15A NCAC 02L Standards (21- Standards): benzene (in samples collected from MW-6, MW-7, MW-8, June 15, 2023 Corrective Actions Evaluation Report Moore County Landfill Aberdeen, North Carolina S&ME Project No. 4358-20-043D I MW-9, MW-11SR/DR, MW-13SR, MW-14, MW-15R, and MW-18), vinyl chloride (in samples from MW-6, MW-7, MW-11SR/DR, MW-14, MW-15R, MW-175, and MW-18), and 1,4-Dioxane (in samples from MW-2, MW-7, MW-8, MW-9, MW-11SR/DR, MW-13SR/DR, MW-14, MW-17SR/DR, MW-18, and MW-19). In November 2018, NCDEQ added 1,4-Dioxane to the monitored analyte list for North Carolina landfills. Since 1,4-Dioxane was added to the monitored parameter list, it has been detected at concentrations exceeding the corresponding 2L Standard. As presented in previous reports, including the 2005 ACM (submitted by HDR) and 2017 ACM (submitted by Golder), the groundwater contaminant source at the facility has been identified as leachate and landfill gas from the closed unlined MSW landfill. Historically VOCs, including the chlorinated alkanes, chlorinated alkenes, chlorinated benzenes, and benzene have been detected at relatively low concentrations at the facility. The contaminant plume originates underneath the closed MSW landfill and in general extends in the downgradient groundwater flow directions toward the west and southwest. Groundwater contamination has been detected to the north in samples from MW-15R, likely due to LFG and localized groundwater flow toward the northern drainage feature. It is believed that some of the VOC detections in groundwater at the facility, and especially in samples from wells MW-6 and MW-15R can be attributed to LFG present in and upgradient of those locations. The relatively high concentrations of methane detected in MW-6 and MW-15R are documented on Table 6. Figures 3 through 8 provide total VOCs isoconcentration contours for conditions observed during each fall semi- annual WQME, performed over the past five years. Due to the recent addition of 1,4-Dioxane, total VOC isoconcentration extents for November 2018 and thereafter, are not directly comparable with prior event extents. For regulatory compliance, the extents of 2L Standards exceedances are appropriate. Figure 9 depicts estimated isoconcentration contours for VOCs with 2L Standard exceedances reported during the October 2022 WQME. Based on the estimated extents of 2L Standard exceedances as shown in Figure 9, some off -site migration of VOCs above the 2L Standards was plausible during the last five-year period, north of wells MW-6 and MW-15R. 1.6 Description of Site Conceptual Model The groundwater contaminant source at the facility has been identified as leachate and LFG from the closed unlined MSW landfill. Water percolating through the cover soil system interacts with waste and generates leachate. Leachate will percolate downward until it reaches the water table aquifer. Once leachate containing COC enters the aquifer, characteristics of their migration in the aquifer are primarily governed by hydraulic pressure gradients and preferred flow paths within the aquifer media. LFG migrating horizontally in the vadose zone away from the landfill can also transport COCs in the vapor phase over relatively short distances. This can result in a gas -to -water phase transfer of low levels of VOCs to uppermost aquifer beyond the MSW landfill limits of waste. In general, surface water and groundwater at the facility flow to the west and southwest toward Horse Creek, which is located along the western property boundary, representing the most significant local hydraulic boundary. Relative to the MSW and C&D landfills, a lesser component of groundwater flow is predicted to the north and south toward adjacent minor unnamed tributaries of Horse Creek. Horse Creek west of the landfill is classified by NCDEQ as a WSII, Water Supply. Historic concentrations of VOCs in groundwater have been highest in samples from monitoring wells located immediately downgradient of the closed MSW landfill (e.g., MW-6, MW-7, and MW-14). Other relatively elevated concentrations of VOCs have been reported in samples collected from MW-11 SR, MW-11 DR, and MW-15R. The June 15, 2023 Corrective Actions Evaluation Report Moore County Landfill �r Aberdeen, North Carolina S&ME Project No. 4358-20-043D same suite of VOCs detected in MW-6 and MW-15R have been detected in samples collected from MW-11 SR and MW-11 DR, intimating that each of the three wells are downgradient of the same contaminant source area. In the 2017 CAER report, Golder stated that elevated VOC concentrations in the vicinity of monitoring well MW- 15R were likely related to LFG. In November 2018 a landfill gas cut-off trench was installed in an area between the MSW landfill and well MW-15R. During the last four monitoring events, no 2L Standard violations were reported for MW-15R. As discussed further in Section 2.3, it is plausible to attribute some of the recent improvements in groundwater quality at MW-15R to passive venting of LFG intercepted by the new gas cut -of trench. The historical presence of methane gas in MW-6 and MW-15 / GP-18 is recorded in Table 6. Two hydrogeologic cross -sections were prepared to depict subsurface conditions, general hydrogeologic characteristics of the aquifer, and recent COC concentrations (see Figure 10). Cross-section A -A' begins on the west side of the active C&D landfill and runs to east following a path through MW-19, MW-8, MW-13SR / MW- 13DR, and MW-6. Cross-section B-B' bisects an area between the MSW landfill and C&D landfill following a path through MW-6, MW-14, MW-7, MW-8, and MW-9. Cross -Section B-B' is oriented generally perpendicular to the direction of shallow groundwater flow. It includes an area of the historically high total VOC concentrations immediately down -gradient of MSW landfill source area. 2.0 Corrective Action Summary The approved MNA voluntary groundwater corrective action was initiated in April 2007. MNA was selected as an appropriate remedy due to the low risk to human health and the environment determined for the known groundwater impacts and the fact that the removal of the contaminant source (the closed, unlined MSW landfill) is not feasible. The data collected during the ACM showed that reducing geochemical conditions did exist and that natural absorption, biodegradation, and molecular dispersion (i.e., attenuation) of VOC was already occurring at the facility. Similar findings were reported by Golder in the 2017 CAER report. An evidence approach to support MNA as an acceptable remedy requires a suitable conceptual site model (CSM) based on site specific geologic, hydrogeologic, and geochemical conditions. Evaluations to be conducted include an assessment of known site contaminants and the presence or absence of degradation products. Site geochemical parameters are evaluated for indicators of a conducive environment and conditions that may limit the attenuation capacity of the effected aquifer. One of the primary lines of evidence involves a review of the groundwater plume behavior with a focus on changes in spatial distributions of contaminants and evaluations of decreasing concentration trends over time. Multiple lines of evidence are assessed to determine the overall effectiveness of the remedy. 2.1 Physical and Chemical Changes In the Aquifer and Plume Characteristics A review of data collected indicates that there have been no significant changes to the field geochemical characteristics of the aquifer during the CAER evaluation period, excluding seasonal variations. There have been changes in the contaminant plume over the CAER five-year monitoring period. Since implementation of the MNA corrective measure, the number of constituents exceeding corresponding 2L Standards has declined along with the number of wells containing a 2L Standard exceedance. For calendar year 2022, the number of constituents at the facility exceeding the 2L Standard declined to two, excluding 1,4-Dioxane added to the monitored analyte list June 15, 2023 Corrective Actions Evaluation Report Moore County Landfill �r Aberdeen, North Carolina S&ME Project No. 4358-20-043D for landfills in 2018. Table 7 provides a summary of the constituents of concern, the locations where they have been detected, and changes to these lists over time. The overall size of the total VOC plume is estimated to fluctuate some over time. As discussed in Section 1.5, total VOC isoconcentration extents for November 2018 and thereafter, are not directly comparable with prior event extents due to the addition of 1,4-Dioxane. Furthermore, given the relatively low concentrations of the COC, some of the apparent fluctuations may be attributed to short-term variances due to normal sampling variations and the ability to accurately quantify contaminant concentrations. Except for 1,4-dioxane, the groundwater COC data set largely suggests trends of overall declining concentrations over time as described further herein. As presented by Golder in the 2017 CAER document, the facility's organic constituents can be divided into two main groups: aromatic and aliphatic organic compounds. The aromatic compounds previously presented for the facility included 1,4-dichIorobenzene; benzene; and chlorobenzene, and the aliphatic compounds identified include 1,1-Dichloroethane; 1,2-Dichloroethane, cis 1,2-Dichloroethene (cDCE); Tetrachloroethene (PCE); Trichloroethene (TCE); and Vinyl Chloride (VC). The new COC for this CAER evaluation period was 1,4-Dioxane, which falls into the aliphatic organic compound group. Literature suggests that 1,4-Dioxane was used as a solvent stabilizer, it is often found in association with releases of other chlorinated solvents. The detection of 1,4-Dioxane does not represent evidence of a new release. 2.1.1 Aromatic Compounds In most cases, aromatic VOCs are readily susceptible to the natural attenuation processes in aerobic environments. Aromatic VOCs degrade slower in the anaerobic conditions found in the subsurface at the facility. Under anaerobic conditions, aromatic VOCs may provide a carbon source for stimulation of biological degradation of chlorinated aliphatic compounds. Therefore, under the mixed -plume scenario present at the facility, natural biodegradation processes for both contaminant classes may be stimulated at the facility (USGS, 2006). 2.1.2 Aliphatic Compounds Aliphatic VOCs are relatively soluble and mobile in groundwater, generally recalcitrant to degradation in aerobic environments, especially when compared to aromatic VOCs. Due to the relatively recalcitrant nature of aliphatic VOCs, higher concentrations may be found further downgradient in groundwater than aromatic VOCs when similar source masses are involved. Unlike aromatic VOCs, biodegradation rates for most aliphatic VOCs are relatively higher in anaerobic aquifer conditions, as compared to aerobic aquifer conditions. Published literature indicates that reductive dechlorination can occur by sequential dechlorination from tetrachloroethene (PCE) —> trichloroethene (TCE) —> cis 1,2-dichloroethene (cDCE) —> vinyl chloride (VC) —> ethene. In anaerobic environments, the highest concentrations of parent compounds PCE and TCE tend to be near the source, with degradation products or daughter products (e.g., such as cDCE, VC, and ethene) located downgradient from the source. During the biodegradation process, the chlorinated hydrocarbon is used as an electron acceptor and chlorine atoms are removed and replaced with hydrogen atoms. In this case biodegradation is an electron donor limited process, controlled by the availability of carbon sources such as organic matter in the aquifer matrix or aromatic VOCs as indicated above. Chlorinated hydrocarbons can also undergo biodegradation through use as an electron doner. In this case the rate of reductive dechlorination is controlled by the availability of electron acceptors such as nitrate, ferric iron, sulfate, or via co -metabolic processes. June 15, 2023 10 Corrective Actions Evaluation Report Moore County Landfill Aberdeen, North Carolina S&ME Project No. 4358-20-043D I Literature reports indicate that the dechlorination sequence can be inhibited or interrupted at the cDCE to VC chloride stage and VC to ethene stage if the aquifer is characterized by weakly reductive conditions. Data obtained during this assessment indicates that suitable conditions exist in site groundwater. In the case of landfills, the degradation of PCE and TCE to daughter products often occurs at or near waste units, which typically produce anerobic conditions. Degradation of chlorinated VOCs in groundwater can produce concurrent plumes of parent compounds and daughter products, with the VC plume generally extending farthest from the source area. When degradation is occurring within the waste mass, clear indications of the degradation sequence can be obscured due to the introduction of the degradation products at the point of release. Given that the source areas for the subject release are within the landfill waste, source area monitoring wells are non-existent. This limitation required that the MNA evaluations make assumptions regarding source concentrations and if the source concentration is constant or decays over time. Based on the monitoring data obtained, the facility exhibits characteristics indicative of reductive dechlorination and biodegradation occurring, suggesting that MNA is an effective remedy. Although 1,4-Dioxane is considered resistant to naturally occurring biodegradation processes, there is some evidence that intrinsic biodegradation can take place under suitable site conditions (Adamson, D et. al. 2015). Published literatures suggest that MNA may be possible when 1,4-Dioxane concentrations are less than 150 microgram per liter (pg/L). The sample size for the groundwater analytical data set for 1,4-Dioxane at the subject site is relatively small. Given an anticipated relatively low attenuation rate, long-term groundwater plume monitoring data is essential. Additional monitoring data is needed to perform an adequate evaluation of MNA as an effective remedy for 1,4-Dioxane. 2.1.3 Geochemistry Analysis of geochemical or indicator parameters (including chloride, dissolved oxygen, ethane, ethene, ferrous iron, methane, nitrate, oxygen reduction potential, total alkalinity, total organic carbon, sulfate, sulfide, and volatile fatty acids) was performed on samples from the "performance monitoring" or MNA monitoring wells. A summary of the results from the geochemical or indicator parameter monitoring can be found in Table 8 (field parameter) and Table 9 (laboratory analytical results). To assess the possibility that chlorinated (aromatic and aliphatic) VOCs are naturally attenuating at the site, geochemical parameters were evaluated based on criteria presented in the Technical Protocol for Evaluating Natural Attenuation of Chlorinated Solvents in Ground Water, Table 2.3 (EPA, 1998). The BIOCHLOR model software includes a form (e.g., score card) which utilizes the same criteria and scoring system. Relying upon field and laboratory data for the October 2022 WQME, score cards were completed for site monitoring wells MW-4, MW-6, MW-8, MW-9, MM-11SR, and MW-15R, and are presented in Appendix II. Site conditions for October WQMEs over the last 5 years report generally similar conditions. The screening protocol scores for wells MW-4, MW-6, MW-8, MW-9, MW-11SR, and MW15R can be interpreted to indicate that there is adequate, too strong evidence for anaerobic biodegradation of chlorinated organics. The field measured dissolved oxygen (DO) concentrations fluctuated over time but were generally between the 0.1 and 0.5 milligrams per liter (mg/L) and oxygen reduction potential (ORP) was generally less than 50 milli -volts (mV) in monitoring wells MW-6, MW-7, MW-8, MW-9, MW-11SR, and MW-15R. Literature reports that ORP levels less than 50 mV indicate that the reductive pathway is possible. Additionally, in general, concentrations of ferrous June 15, 2023 11 Corrective Actions Evaluation Report Moore County Landfill Aberdeen, North Carolina S&ME Project No. 4358-20-043D I iron reported for monitoring wells MW-2, MW-6, MW-7, MW-8, MW-9, MW-11SR, and MW-15R support the presence of a reducing geochemical environment. As noted in the previous section, a reducing geochemical environment is generally supportive of reductive dechlorination (i.e., biodegradation) of chlorinated VOCs. The biological process of methanogenesis can produce methane associated with reductive dechlorination. This process typically occurs relatively close to the contaminant source area. Dissolved methane concentrations greater than 0.5 mg/L have been reported in groundwater samples from monitoring wells MW-6, MW-7, MW-8, MW-9, MW-11SR, and MW-15R. Observed methane concentrations greater than 0.5 mg/L could indicate reductive dechlorination of chlorinated VOCs. Since dissolved methane can also be associated with landfill gas migrating through the vadose zone, this additional source needs to be considered. Most groundwater monitoring wells at the site are not monitored for methane gas. Methane gas is monitored at MW-6 and GP-18 and has been detected above the lower explosive limit for methane in these wells. The process of sulfate reduction typically occurs further from the source area, when compared with methanogenesis. Reported sulfate concentrations were generally below 20 mg/L in monitoring wells MW-1, MW 2, MW-3, MW-6, MW-7, MW-9, MW-11 SR, and MW-15R. Concentrations of sulfate greater than 20 mg/L can inhibit reductive dechlorination. Similarly, nitrate concentrations greater than 1 mg/L can inhibit reductive dechlorination. Nitrate in groundwater monitoring wells MW-1, MW-3, MW-6, MW-7, MW-8, MW-9, MW-11SR, and MW-15R were generally not reported above 1 mg/L. Chloride in groundwater is generally non -reactive. Chloride should accumulate in groundwater in areas where reductive dechlorination is occurring. During the current MNA evaluation period, chloride has been routinely detected at concentrations greater than 2 times the background concentration in samples from MW-2, MW-4, MW-6, MW-7, MW-8, MW-9, and MW-11SR, providing evidence of reductive dechlorination of chlorinated COCs. In areas of reductive dechlorination of chlorinated VOCs, there should be a positive correlation between zones of microbial activity and increased alkalinity. Increases in alkalinity result from the dissolution of minerals in the aquifer matrix, which is driven by the production of carbon dioxide by the metabolism of microorganisms. The alkalinity of groundwater samples was determined by laboratory analysis for total alkalinity during the MNA evaluation period. The data presented in Table 9 provide evidence for total alkalinity concentrations for wells MW-2, MW-4, MW-6, MW-7, MW-8, MW-9, MW-11 SR, and MW-15R down -gradient of the source area being elevated at least two times the background values well MW-5. Similarly, analytical results summarized in Table 9 also show elevated concentrations of dissolved carbon dioxide in downgradient wells MW-3, MW-4, MW-6, MW- 7, MW-8, MW-9, MW-11SR, and MW-15R when compared with background well MW-5, providing additional supporting evidence of biodegradation of chlorinated VOCs. The sequential reduction of PCE -> TCE -> cDCE -> VC is suggested by the groundwater analytical data obtained for the facility. PCE, TCE, cDCE, and VC were detected during the early years of groundwater monitoring at concentrations that exceeded their corresponding 2L standards. Ethene is the anticipated final daughter product of reductive dechlorination of VC. MNA performance monitoring for ethene has resulted in only two estimated detections. VC concentrations in wells near the MSW source area have declined overtime, with the last two years reporting most VC detections in the 2 pg/L or less range. The relatively low VC concentrations currently observed coupled with detection limits of 1 pg/L and greater for ethene, may give reason for the non -detection of ethene, thus the absence of ethene as an indicator parameter is not a concern. Under these conditions, the utility of ethene is limited as this indicator parameter to support the reductive dechlorination of VC. June 15, 2023 12 Corrective Actions Evaluation Report Moore County Landfill Aberdeen, North Carolina S&ME Project No. 4358-20-043D ICI Based on the evaluations presented above, facility geochemical parameters indicate adequate to strong evidence for anaerobic biodegradation of chlorinated VOCs and suggest that anaerobic biodegradation of the chlorinated VOCs is naturally occurring. Furthermore, the presence of aromatic hydrocarbons within the plume and the generally reducing geochemical conditions also allow for the degradation of aromatic hydrocarbons as a carbon source during biological degradation of chlorinated aliphatic hydrocarbons. It is recognized that biodegradation processes can slow as chlorinated VOCs and aromatic hydrocarbon concentrations diminish with time. 2.1.4 BIOCHLOR Model Based on historic groundwater analytical data, the highest groundwater contaminant concentrations have generally occurred in the northern portion of the contaminant plume, immediately west of the MSW landfill. This area also exhibited greater horizontal extents of total VOCs as indicated on Figures 3 through 8; therefore, this area was selected for a performance evaluation of MNA utilizing the BIOCHLOR model. Monitoring wells MW-6, MW-11 SR, and MW-4 represent the modeled plume centerline, chosen due to the position of the wells, simulating the estimated groundwater flow from the MSW landfill source area to Horse Creek, the dominant local groundwater discharge point. The prior CAER report utilized MW-15R as a well immediately down -gradient of the source area for the BIOCHLOR modeling performed. It is S&ME's opinion that MW-6 is more representative of the groundwater flow path assessed, thus MW-15R was not utilized in the BIOCHLOR modeling for this CAER report. Furthermore, S&ME believed that the gas cut-off trench installed in November 2018, immediately south of MW- 15R has had localize influence on groundwater quality, thus use of MW-15R in the model could result in model predictions that were not representative of the flow -path assessed. The start date for the site model was 1968, the year when waste was reportedly first placed in the closed MSW landfill. Historically, the first model simulations associated with the MNA evaluation were performed after the October 2007 WQME; therefore, the model was calibrated at 39 years and then projected to 100 years. Each subsequent model was calibrated based on the same concept and the model was calibrated using a duration period (time in years) equal to the difference between the modelled scenario year and 1968. The initial model created in October 2007 showed the simulated biodegradation of PCE, TCE, DCE, and VC. After October 2007, there were no detections of PCE or TCE in the monitoring wells along the modeled plume centerline. Since PCE and TCE were not detected after 2007, the original model was considered to be calibrated for PCE and TCE during the October 2007 modeling event and the values for their 1 st order decay coefficient were used throughout. The BIOCHLOR modeling program generates plots that compare concentrations of PCE, TCE, cDCE, VC, and ethene over time with no degradation, to concentrations where sequential 1 st order biological attenuation is occurring. For this CAER report review period (December 2017 — October 2022), the model was run with 49-year and 100-year simulations, for wells MW-6, MW-11 SR, and MW-4, using PCE, TCE, DCE, VC, and ethene as the modeled constituents. Several model runs were performed using source area concentrations and primary model inputs that were consistent with prior modeling efforts conducted by others. The output results did not show reasonable calibration. Considering groundwater analytical results for the last five years, for wells immediately down gradient of the MSW source area, S&ME inferred that source area concentrations have likely diminished. Improvements to model calibration were achieved utilizing lower source concentrations. Consistent with prior modeling efforts, source concentrations applied in the model were considered constant for the duration of each modeled scenario. For the centerline wells there were several non -detections of modeled constituents in October 2022. The detection limit was relied upon when non -detections were reported. The data input page and the associated constituent plots for the 49-years and 100 years simulations are provided in Appendix III. June 15, 2023 13 Corrective Actions Evaluation Report Moore County Landfill �r Aberdeen, North Carolina S&ME Project No. 4358-20-043D In summary, the results of the BIOCHLOR modeling conducted annually from December 2017 through October 2022 predict concentrations of DCE and VC that plot on or below the sequential first order decay curve in each model run, indicating that degradation of the constituents is occurring. PCE, TCE, and ethene were generally not detected during the last 5 years, therefore, they can no longer be assessed with the model. The BIOCHLOR model outputs exhibit concentrations that decline to non -detectable concentrations before the end of the graphs, which represent the location of Horse Creek. There appears to be little to no difference between the curves on the 49-year and 100-year simulations, indicating the contaminant plume is currently at or near a steady state condition and changes in its downgradient expanse should be limited. The October 2022 isoconcentration contours suggest the potential for off -site migration of VOCs to the north near MW-15R. In this area a limited separation distance exists between the edge of waste and the property line. As discussed in Section 2.1.5, there are trends of improving groundwater VOC concentrations at MW-15R. The benzene plume in the vicinity of monitoring wells MW-18 and MW-19, is estimated to be near the eastern property line. As discussed in Section 2.1.5 below, concentrations at MW-19 appear to be generally stable. 2.1.5 Trends in Contaminant Concentrations The evidence approach to support MNA as an acceptable remedy indicates that trends of decreasing COC concentrations over time, should be considered a primary line of evidence. Appendix IV presents the intra-well concentration trend graphs for analytes exceeding 2L Standards (i.e., benzene, vinyl chloride, and 1,4-Dioxane) during the December 2017 through October 2022, CAER evaluation period. The chart formats developed include: Five Benzene charts, each with a group of wells that occur along one of the five conceptual flow paths originating at or near the MSW landfill and ending near Horse Creek. Five VC charts, each with a group of wells that occur along one of the five conceptual flow paths originating at or near the MSW landfill and ending near Horse Creek. cDCE charts to depict the daughter product of PCE and TCE. One chart for wells that are directly adjacent to the MSW landfill and another chart for wells that are directly adjacent to the C&D landfill. Charts for PCE and TCE were not prepared due to the number of non -detections. 1,4_Dioxane charts. One chart for wells that are directly adjacent to the MSW landfill and another chart for wells that are directly adjacent to the C&D landfill. In general, the charts for benzene, cDCE, and VC depict overall trends of declining concentration with time. For some wells, segments of the benzene, cDCE, and VC charts where concentrations have declined to relatively low -levels or concentrations approach method detection limits, make it difficult to discern a trend. These occurrences likely reflect natural temporal variability and/or limitation of laboratory analytical accuracy, thus they do not necessarily indicate that MNA is no longer a viable remedy. Benzene and Vinyl Chloride were present at concentrations greater than the corresponding 2L Standards during this CAER evaluation period. During the CAER review period, concentrations for cDCE were less than the corresponding 2L Standard. Concentration trends for 1,4-Dioxane over time are generally less obvious. Published literature reports that detections of 1,4-Dioxane by routine analytical methods may be complicated by the compound's relatively high solubility in water and chlorinated VOC interferences. The population of the 1,4-Dioxane data set is relatively small due to its introduction in 2018, thus the data set is of lower statistical power. June 15, 2023 14 Corrective Actions Evaluation Report Moore County Landfill Aberdeen, North Carolina S&ME Project No. 4358-20-043D ICI_ The trend charts provide a powerful qualitative visual analysis of intra-well COC concentrations over time. As an additional evaluation tool, the Mann -Kendall statistical test was also applied to analyze trends in concentrations over time for the same data set. This statistical test assesses if there is a monotonic upward or downward trend of the variable of interest (COC concentrations) over time. A monotonic upward (downward) trend means that the variable consistently increases (decreases) through time, but the trend may not be linear. The Mann -Kendall test is broadly accepted by many regulatory agencies since it applies a quantitative evaluation to trends in concentrations over time. However, like most statistical tests, the user must consider inherent limitations associated with the test method. For the current CAER period evaluations, the tests were constrained to data obtained between October 2015 through October 2022. This protocol made the Mann -Kendall test results more rigorous by excluding more substantial concentration changes present in the full historic data set. As recommended for the Mann Kendall test, non -detection values were modified for the test. Concentrations reported as non -detections were converted to values'/z of the reporting limit. The Mann -Kendall test indicated the following intra-well trends: MW-4: VC (NA), cDCE (S), Benzene (AND), and 1,4-Dioxane (NTD). MW-6: VC (D), cDCE (D), Benzene (D), and 1,4-Dioxane (D). MW-7: VC (NTD), cDCE (NTD), Benzene (D), and 1,4-Dioxane (NTD). MW-9: VC (NA), cDCE (S), Benzene (S), and 1,4-Dioxane (NTD). MW-14: VC (S), cDCE (D), Benzene (D), and 1,4-Dioxane (NTD). MW-15R: VC (S), cDCE (NTD), Benzene (D), and 1,4-Dioxane (NA). MW-11SR: VC (D), cDCE (D), Benzene (NTD), and 1,4-Dioxane (D). MW-11 DR: VC (D), cDCE (D), Benzene (NTD), and 1,4-Dioxane (D). MW-13SR: VC (NA), cDCE (S), Benzene (D), and 1,4-Dioxane (1). MW-13DR: VC (AND), cDCE (D), Benzene (NA), and 1,4-Dioxane (NTD). MW-18: VC (D), cDCE (D), Benzene (D), and 1,4-Dioxane (S). MW-19: VC (NA), cDCE (NA), Benzene (AND), and 1,4-Dioxane (S). S = Stable, D = Decreasing, I = Increasing, NTD = No Trend Discernable, AND = All Non -Detects, NA = No trend suggested due to a high percentage of non -detections. The Mann -Kendall tests contained in Appendix V generally indicated stable or declining concentrations of the COCs at the wells evaluated, with some trends not discernable due to a high percentage of non -detections. A high percentage of non -detections of COCs is a favorable and desired outcome. As mentioned in the discussion of time vs concentration charts, detections of relatively low concentrations and/or concentrations approximating the respective reporting limits are conditions that hamper analyses of trends over time. These occurrences likely reflect either natural temporal variability and/or limitations of laboratory analytical accuracy, thus they do not necessarily indicate that MNA is no longer a viable remedy. The Mann -Kendall test was performed on the 1,4-dioxane data set as an initial screening tool. The Mann -Kendall test requires at least four data points to perform the calculations. However, it is S&ME opinion that the current 1,4-dioxane data set does not have adequate statistical power to provide for reliable conclusions and associated decision making. June 15, 2023 15 Corrective Actions Evaluation Report Moore County Landfill .� Aberdeen, North Carolina S&ME Project No. 4358-20-043D 2.2 Refining the Conceptual Model After completing the initial phase of the MNA performance evaluation period, the original conceptual model presented in the 2005 ACM submitted by HDR, in the 2012 and 2017 CAER reports, and the one presented in Section 1.5 of this report remain accurate depictions of site conditions. In the last five years there has been a growing number of low-level detections of certain VOCs at the facility, which makes it increasingly difficult to accurately assess recent trends in concentrations over time, given that some of the variances observed between monitoring events may not be statistically significant. This and other factors limit the functionality of the BIOCHLOR model to accurately simulate some of the more recent site conditions. This is a common challenge when concentrations of COCs approach the laboratory MDLs. This technical limitation need not overshadow the fact that an increase in the number of low-level detections is a positive outcome. Assessing trends in COC concentrations over time is considered a primary line of evidence for evaluations of MNA. The BIOCHLOR model was run for the CAER review period with results indicating simulated biodegradation of COCs as first -order biotransformation. Furthermore, site geochemical data and indicator parameters provide secondary evidence of subsurface conditions that are favorable for biodegradation to occur at the facility. There is some evidence that Total Organic Carbon (TOC) concentrations decrease with increased distance from the source, with the more apparent area for this occurrence located west of wells MW-8 and MW-9, represented by wells MW-1, MW-2, and MW-3. Since reductive dechlorination is often limited by the amount of available organic carbon, such as provided for in MSW landfill leachate and consumed by the biodegradation process; a slower rate of biodegradation away from the landfill (i.e., an organic carbon source) is expected. Wells MW-1, MW-2, MW-3, MW-8, and MW-9 report cDCE and VC concentrations less than the corresponding 2L Standard, thus lower TOC concentrations in this area have had no impact on groundwater quality compliance. VC and cDCE are among the final reductive dechlorination compounds produced and can be more recalcitrant daughter compounds when compared with other compounds involved earlier in the process. Stalling of the dechlorination process at the cDCE or VC steps can occur where site conditions are less suitable for supporting the process. A review of site geochemistry data collected indicates suitable conditions for reductive dechlorination. VC has been detected in down -gradient well MW-18 but not in well MW-19, located further downgradient. S&ME believes that VC detected at MW-18 migrated from the MSW landfill and the area represented by well MW-14. The simplified groundwater flow paths depicted in Figure 2 cannot fully capture heterogeneous aquifer subtleties that influence groundwater flow beneath the facility. The presence of relatively low concentrations of VC in down - gradient monitoring well MW-18 does not indicate that MNA is an unsuitable corrective measure, rather it likely indicates a slower degradation rate for VC, and that additional travel distances from the source area may be necessary to achieve CAP cleanup goals. Groundwater contamination detected to the north in samples from MW-15R, is likely due to LFG and a minor component of groundwater flow toward the northern drainage feature. It is believed that some of the VOC detections in groundwater at the facility, and especially in samples from wells MW-6 and MW-15R can be attributed in part to LFG present in and upgradient of those locations. Recent trends in COC concentrations over time at well MW-15R are noteworthy. Well MW-15R is in the immediate vicinity of the passive LFG cut-off trench installed in November 2018, as part of an LFG remediation plan. Groundwater analytical results received after November 2018, indicate a higher percentage of non -detections of June 15, 2023 16 Corrective Actions Evaluation Report Moore County Landfill Aberdeen, North Carolina S&ME Project No. 4358-20-043D ICI_ VC and the last four monitoring events reported consistently lower concentrations of benzene. Although additional time vs concentration data is needed to substantiate this opinion, it appears plausible to attribute all or part of the apparent improvements in groundwater quality at MW-15R to passive venting of LFG intercepted by the cut-off trench. Recognizing the potential benefits of enhanced LFG management discussed in Section 1.2, Moore County initiated a pilot test in 2022. The pilot test involved localized improvements to the MSW cover system and installation of two additional passive gas vents that tapped into transmissive vadose zone sandy sediments forming a partition between two MSW landfill units. At this time, it is premature to forecast benefits the cover system improvements and/or the additional venting of LFG from the new vents wells may provide. 2.3 Corrective Action Method Evaluation The MNA corrective action evaluations conducted provide evidence that biodegradation is occurring and that there is a reduction in contaminant concentrations (with respect to chlorinated ethene COCs). The BIOCHLOR model and associated EPA screening score card tool were used to evaluate biodegradation of COCs. The BIOCHLOR model is designed to evaluate changes in concentrations that occur along a flow path that is linear and with groundwater flow that is directly down -gradient. Relying solely upon site topography and assuming a minor component of shallow groundwater flow toward the north or northwest, localized off -site migration of groundwater COCs, although likely limited in extent, is estimated in the area north of MW-6 and MW-15R. Both primary (e.g., changes in COC concentrations over time) and secondary lines of evidence (e.g., site geochemistry and other indicator parameters) presented herein converge to support MNA as an appropriate groundwater corrective action remedy for the Moore County Landfill. As stated previously in this report, there is sufficient evidence showing that reductive conditions exist and that reductive dechlorination is occurring. Due to sufficiently strong reductive conditions, aromatics compounds, more specifically benzene, chlorobenzene, and 1,4- dichlorobenzene may not breakdown as easily as they would in more aerobic conditions. However, they may be utilized and degraded as a carbon source in a mixed anaerobic plume scenario, effectively supporting reductive dechlorination. In the last five years, concentrations of benzene and 1,4-dichlorobenzene have not decreased significantly at wells immediately down -gradient of the MSW source area, indicating a constant source remains in the waste mass. This condition produces low single digit benzene concentrations greater than the corresponding 2L Standard but less than the corresponding EPA Maximum Contaminant Level (MCL) currently exists. Conversely, 1,4-dichlorobenzene concentrations are one order of magnitude or more, less than the corresponding 2L Standard. Concentrations of the aliphatic COCs have been decreasing and there has not been a detection of PCE or TCE above the corresponding 2L Standards since October 2007. Historic methane monitoring data reported persistent relatively high levels of methane at compliance monitoring probes GP-10, MW-6, and MW-15 / GP-18. In 2005 Moore County installed 12 passive gas vents into 2 trenches dug into waste to the south of MW-15 along the facility's northern property boundary to attempt mitigation of probable off -site migration of methane gas. In 2007, 3 more trenches with 12 more passive gas vents were added to the passive gas trench system. In 2005, HDR added a contingency to MNA, suggesting that the facility initiate more aggressive methane corrective actions if the gas vent/trench system was not effective at keeping LFG from crossing the compliance boundary. Following the submittal of the May 2012 CAER, it was determined that more aggressive methane corrective actions should be taken and on May 16, 2013, Moore County submitted the Contingency Plan Update and Implementation Plan — Revised. The contingency plan was approved by the NCDEQ in a letter dated June 5, 2013, and in accordance with the approved plan, three additional vents, GV-30, GV-31, June 15, 2023 17 Corrective Actions Evaluation Report Moore County Landfill �r Aberdeen, North Carolina S&ME Project No. 4358-20-043D and GV-32 were installed in February 2014, to the south of the existing trench -vent system. These passive gas vents have regularly produced high concentrations of LFG. Based on persistently elevated levels of methane at compliance monitoring probe MW-15 (GP-18), Golder prepared a Gas Remediation Plan. As part of a Gas Remediation Plan, the LFG cut -off -trench was installed in November 2018, in an area between the closed MSW landfill and monitoring well MW-15 (GP-18). Following installation of the LFG cut-off trench, LFG monitoring data continued to suggest the potential for methane migrating offsite to the north. Subsequently, Moore County evaluated options that would aid in the management of landfill gases, which can contribute to groundwater exceedances. In 2022, Moore County placed and graded additional clean fill soils in certain low areas on the MSW cover system, to improve positive surface drainage. Reduced infiltration into the waste should reduce generation of landfill gases, and transfers of vapor phase constituents to underlying groundwater. In June 2022, S&ME initiated a pilot test involving installation and monitoring of two new passive landfill gas vents that tap into transmissive vadose zone sandy sediments forming a narrow partition between two MSW landfill units. Landfill gas monitoring continues for the pilot test, conducted to assess a potential to enhance management of landfill gas migration in the vicinity of monitoring point GP-18. Supplemental measures to aid in mitigation of horizontal migration of LFG from the MSW landfill should further enhance the currently viable MNA of VOCs in facility groundwater. 2.4 Impacts At The Compliance Boundary and Off -Site Migration As stated in Section 2.3 and depicted on Figure 9, it is plausible that benzene and VC concentrations in groundwater may extend beyond a portion of the northern compliance boundary (e.g., area north of MW-6) at concentrations greater than their respective 2L Standards. The BIOCHLOR models, trend charts, and Mann Kendall test suggest that the contaminant plume is generally stable or shrinking. Accordingly, it is forecasted that the contaminant plume may not migrate significantly further to the north. The aerobic conditions expected north of the property boundary will likely degrade the aromatics and potentially vinyl chloride. The creeks surrounding the landfill property represent common hydraulic boundary conditions, which limit lateral migration of groundwater COCs at a significant distance from the property boundary. Figure 11 presents the desk -top water well receptor information developed previously by Golder, which was based on a review of the available public water supply GIS database. Based on this receptor information, there are no downgradient water supply well receptors identified within 1500 feet of the contaminant source (e.g., MSW landfill). Considering the absence of downgradient water well receptors and that VOCs are at relatively low concentrations, these factors support continued MNA for the groundwater remedy. As shown on Table 5, during 2017 — 2022 CAER monitoring period 1,4-Dioxane was detected in samples from SW-1, SW-3, and SW-4 at concentrations greater than the 15A NCAC 02B, NC Protective value. Currently, there is no corresponding 15A NCAC 02B surface water standard for 1,4-Dixoane. No other VOCs were detected with concentration greater than a corresponding 15A NCAC 02B surface water standard or NC Protective values. Table 6 provides recent methane gas detections at property boundary compliance points. As presented in Sectior 2.3, a pilot test was initiated in 2022, exploring an option to improve methane gas control. The pilot test efforts are on -going. In 2022 Moore County reestablished efforts to develop a dialog with the Blake family, the owner of the parcel to the north of the MSW landfill. It is Moore County's desire to negotiate purchase of additional land to the north. The facility's current property boundary provides limited separation between the edge of waste for the June 15, 2023 18 Corrective Actions Evaluation Report Moore County Landfill �r Aberdeen, North Carolina S&ME Project No. 4358-20-043D close MSW landfill and the off -site property to the north, thus additional buffer property is needed. The property to the north is mostly undeveloped, with no structures within 400 feet or greater of the facility's, norther property boundary. Thus, off -site migration of methane gas presents a relatively low risk to human health and the environment. 3.0 Conclusions and Recommendations In conclusion, based on our evaluation of the five-year CAER period from December 2017 through October 2022, it is possible that groundwater impacts extend slightly beyond the property boundary on the northern side of the facility as estimated on Figure 9. The County is currently exploring the option to acquire buffer property in this area to mitigate potential risks to human health and the environment. The BIOCHLOR modeling performed suggests that the plume has reached stabilization. This is consistent with observed trends of VOCs generally declining over time as depicted in time vs concentration charts (Appendix IV) and by a reduction in the number of COC detected with concentrations greater than the 2L Standard during the CAER period (see Table 7). One new COC, 1,4-Dioxane was introduced during the CAER review period due to NCDEQ's addition of this volatile organic compound to the target compound list for North Carolina landfills. Published literature reports that although this compound is resistant to naturally occurring biodegradation processes, biodegradation in groundwater can take place under suitable site conditions. The sample size for the facility's 1,4-Dioxane groundwater analytical data set is limited and provides limited statistical power. This limitation is manifested in time vs concentration charts that exhibit a general lack of discernable trends over time. Acquisition of several years of additional time series data for 1,4-Dioxane, collected during future semi-annual monitoring events is recommended. Additional data is needed prior to selection of a remedy, which could include MNA. A Contingency Plan Update involving 1,4-Dioxane should be prepared and submitted to NCDEQ prior to the end of the next 5- year CAER evaluation period. It appears that the addition of the LFG cut-off trench between the edge of waste and MW-15R, resulted in improved groundwater quality at MW-15R, however, non -compliant methane gas conditions persist at property line monitoring point GP-18. The off -site property to the north is an undeveloped pine tree woodland area, with no structures within 400 feet or more of the northern property line; therefore, the methane LEL exceedance is not currently known to pose a risk to human health. In 2022, Moore County initiated a pilot test, which involved repairs to improve surface drainage off the MSW landfill cover system and installation of two additional passive landfill gas vents. Reduced infiltration of water into the waste should reduce generation of landfill gases, and transfers of vapor phase constituents to underlying groundwater. Measured methane concentrations detected at existing in -waste methane vents GV-30, GV-31, and GV-32 and new vents GV-35 and GW-36 installed in transmissive vadose zone sediments, have been relatively high; therefore, these vents help limit off -site landfill gas migration. Based on the age of the MSW waste it is not anticipated that additional in -waste passive or active vents/wells would be an appropriate remedy. The limited separation distance between the edge of waste and the northern property line imposes a physical limitation. During the CAER review period, the County initiated dialog with the adjoining property owner to the north of MW-6 and GP-18. The County desires to resolve this issue by purchasing the adjoining property to the north, to increase their buffer area. The County respectfully requests additional time to explore the current feasibility of the desired property acquisition, which represents the most reasonable and reliable solution to reported exceedances of methane LEL conditions at the northern property line. June 15, 2023 19 Corrective Actions Evaluation Report Moore County Landfill Aberdeen, North Carolina S&ME Project No. 4358-20-043D ICI_ Surface water monitoring has not indicated exceedances of corresponding 15A NCAC 02B surface water standards. 1,4-Dioxane, a new groundwater COC has been detected in surface water samples collected from locations SW-1, SW-2, and SW-3 at concentrations that exceed the 15A NCAC 02B North Carolina In -Stream Target Value set at 0.35 pg/L for Class WS (I-V) surface waters; however, no 2B Standard currently exists. Based on the analytical results received and absence of a 02B Standard, it appears that offsite migration of 1,4-Dioxane is not currently known to pose a risk to human health and the environment via the surface water pathway. Based on the current information and as shown on Figure 11, no downgradient receptors have been identified within a 1500-foot radius of the source area (closed MSW landfill). Because no potential risk receptors were identified during the Golder desktop receptor survey, continuation of MNA for the remediation of VOCs at the facility is proposed, with continued assessment of the likelihood of the contaminants of concern crossing the compliance boundary at concentrations above the 2L Standard. Should a new receptor be identified in the immediate area or if the plume appears to be migrating off -site above the 2L Standard, the installation of additional monitoring wells and/or re-evaluating the sole use of MNA as a remedy may be appropriate; however, this situation does not currently exist. There is not an evident need to implement a contingency plan to address VOC concentrations in groundwater. The County continues efforts to assess the feasibility of obtaining additional buffer property to the north to address methane non -compliant conditions and the potential of slight off -site migration of groundwater COC. There is strong evidence of reductive dechlorination at the facility based on indicator parameter results, the BIOCHLOR modeling, and declining trends in VOCs; therefore, continuation of MNA monitoring is recommended, along with on -going pilot testing discussed herein. At the end of the next five-year MNA monitoring period, the need for an addendum to the ACM will be evaluated. 4.0 Refences Department of Environment and Natural Resources, Division of Water Quality, 75A NC Administrative Code Subchapter 28.0200 Classifications and Water Quality Standards Applicable to Surface Waters and Wetlands of NC, November 2019.
