(Electronic Copy) %%%I) GOLDER September 21, 2022 GL2013788122 Executive Summary Golder Associates NC, Inc. (Golder), a member of WSP, is submitting the enclosed Water Quality Monitoring Report on behalf of WI High Point, LLC, which documents the results from the July 5 - 7, 2022 semi-annual compliance monitoring event at the High Point Construction and Demolition Landfill. Pore water sample locations PWS-4 and PWS-5 did not encounter the water table and surface water locations SW-1 and SW-2 were dry; therefore, these points were not sampled. Three North Carolina (NC) Appendix I inorganic constituents (barium, chromium, and cobalt) were detected at quantifiable concentrations above their applicable groundwater standards during the August 2021 event in samples from one or more downgradient wells. As described below, additional background data are being collected to further evaluate exceedances of Appendix I metals. Cobalt was also detected at one or more wells at estimated concentrations below the practical quantitation limit (PQLs) but above the NC 2L Standard during this event. As the concentrations are estimated (i.e., non -quantifiable) concentrations below the method reporting limits, per the 15A NCAC 02L .0202 (b)(1), no regulatory actions should be taken for estimated values below the reporting limits (a.k.a. PQLs) that are above groundwater standards. Indicator parameters iron, manganese, and total dissolved solids (TDS) were detected at quantifiable concentrations above their respective NC 2L Standards in samples from one or more downgradient wells during this event, as they have been during previous events. As presented in previous reports and alternate source demonstrations (ASDs), the inorganic concentrations reported in the groundwater samples are generally within natural background concentrations. Piezometer P-3, which is located upgradient of the waste unit, was sampled during the July 2022 event to collect additional inorganic constituent data to further evaluate concentrations of inorganic constituents recently detected in samples from downgradient wells. This was the seventh of ten planned background sampling events for this piezometer. Two NC Appendix I volatile organic compounds (VOCs) were detected at quantifiable concentrations above the NC 2L Standard in samples from one or more downgradient wells during the July 2022 event: benzene, and vinyl chloride. Vinyl chloride was detected at an estimated concentration above the NC 2L Standard in the sample from MW-7S. Additionally, 1,4-dioxane was detected at quantifiable concentrations above the NC 2L Standard in samples from one or more downgradient wells during the event. 1,4-dioxane was analyzed per the May 30, 2018, NC DEQ memorandum and is not part of the facility permit -required testing. Generally, concentrations of VOCs are consistent with historical data with the exception of vinyl chloride at MW-7S. Cobalt was detected at a quantifiable concentration above the applicable surface water standard at downgradient surface water point SW-5 during this event. Based on published stream sediment metals data for Guilford County, NC, the cobalt concentration in the sample from SW-5 is within the range of historical concentrations for this location and are evaluated further in this report. Therefore, in the absence of any other indicators, no further action is recommended at this time. 1,4-dioxane was detected at quantifiable concentrations above the Human Health Standard in samples from SW-3, SW-4, SW-5, and SW-6 during the event. No NC Appendix I VOCs were detected in samples from the surface water monitoring locations during the event. Due to the relatively low horizontal groundwater flow rates for the facility, WI High Point Landfill, LLC continues to evaluate the effects of the soil cap and landfill gas vents, which were installed in 2017, %N%I) GOLDER September 21, 2022 GL2013788122 on groundwater quality along the western waste boundary at MW-2 and MW-6. Nested well pair MW-4S/D are located near the western facility boundary due southwest of the C&D landfill. An upward component of groundwater flow is measured at MW-4S/D (i.e., the unnamed tributary is a receiving stream and benzene concentrations detected at MW-2, MW-6, MW-8, and AMW-2 are not likely to extend off site). Further, results from pore water sample PWS-6 does not indicate the presence of VOCs. Based on these results, the facility will continue groundwater monitoring in accordance with the requirements of the Assessment Monitoring Program as outlined in Title 15A NCAC 13B .0545, the Work Plan, and Addenda. The next semi-annual monitoring event is tentatively scheduled for January 2023. %N%I) GOLDER September 21, 2022 GL2013788122 Table of Contents 1.0 INTRODUCTION.........................................................................................................................................1 1.1 Site Description and Background.....................................................................................................1 1.2 Compliance Monitoring History........................................................................................................1 1.3 Hydrogeologic Setting......................................................................................................................3 2.0 FIELD PROGRAM, MONITORING RESULTS AND DISCUSSION...........................................................4 2.1 Visual inspection Program...............................................................................................................4 2.2 Well Network and Groundwater Elevation Measurements..............................................................4 2.3 July 2022 Groundwater and Surface Water Monitoring Event........................................................4 2.4 Laboratory Analysis Program...........................................................................................................5 3.0 LABORATORY AND FIELD QA/QC..........................................................................................................5 4.0 DATA EVALUTION.....................................................................................................................................6 4.1 North Carolina Groundwater and Surface Water Quality Standard Comparisons ..........................6 5.0 CONCLUSIONS..........................................................................................................................................7 6.0 REFERENCES............................................................................................................................................8 1IF_114*.

The active C&D Landfill is owned and operated under Permit No. 41-16 issued by the NC Department of Environmental Quality (DEQ). 1.1 Site Description and Background The location of the facility is shown on the inlay on Figure 1. As presented, High Point C&D Landfill is located along Riverdale Road within the city limits of Jamestown in Guilford County, NC. The site consists of approximately 154 acres, of which, approximately 17.2 acres is currently permitted as the Phase 1 and Phase 2 waste units. There are three small unnamed streams that traverse the site and flow into an unnamed tributary of Richland Creek, which forms the southern property boundary as shown on Figure 1. The first unnamed tributary is a southwest trending stream that forms the north-western property boundary. The second tributary is a southwest trending drainage in the center of the property and lies just east of the Phase 2 waste unit. The third tributary is a southwest trending drainage in the eastern portion of the site. A large, constructed pond is located near the eastern property boundary. A small storm water basin was constructed in the northwest corner of the facility and a larger storm water basin was constructed along the southwestern part of the site during the construction of Phase 1. Topographic surface elevations at the facility range from approximately 700 to 820 feet above mean sea level. The western portion of the site mainly consisted of trees and heavy brush before Phase 1 of the C&D landfill was constructed. Now, most of that area consists of landfill operations. The eastern portion of the site has historically been used for agricultural purposes. A reclamation facility is located at the northernmost part of the site. A large portion of the surrounding properties are agricultural, sparse residential, or owned by the City of High Point for operations associated with Kersey Valley Landfill. An unpermitted landfill was documented to exist approximately 2,200 feet west of the High Point C&D Landfill (Babb & Associates, 2020). 1.2 Compliance Monitoring History Groundwater monitoring at the facility was initiated in October 2003 after approval of the Groundwater Monitoring Plan by the NC DEQ. Currently the facility's monitoring network is comprised of eight monitoring wells (MW-1, MW-2, MW-3, MW-4S, MW-5, MW-6, MW-7S, and MW-8), which monitor the uppermost aquifer beneath the facility. Monitoring wells MW-7S and MW-8 were installed in July 2006 to monitor the Phase 2 expansion at the facility. Two assessment monitoring wells, AMW-1 and AMW-2 were installed in December 2016. In addition to the groundwater monitoring points, the facility's monitoring network includes six surface water sampling points, SW-1 and SW-3, which are upstream from the waste area, and SW-2, SW-4, SW-5, and SW-6, which are downstream monitoring points. Monitoring points SW-5 and SW-6 were added in the May 2019 revision of the Water Quality Monitoring Plan. These points are sampled in conjunction with the groundwater monitoring wells in accordance with the facility's permit. Vinyl chloride and benzene were detected in the sample from downgradient monitoring well MW-2 at concentrations above their respective reporting limits and NC 2L Standards during the July 2014 %N%I) GOLDER September 21, 2022 GL2013788122 sampling event. On February 3, 2015, an Alternate Source Demonstration (ASD) was submitted in response to this detection that provided evidence that an unidentified source other than the waste unit is likely responsible for the volatile organic compounds (VOCs) detected in the samples from MW-2. On March 2, 2015, NC DEQ issued a response letter that allowed an additional six months to assess potential sources of VOCs. Benzene was detected in the sample from MW-2 at a concentration above the SWSL and NC 2L Standard during the August 2015 sampling event and the facility transitioned to an Assessment Monitoring Program. An Assessment Monitoring Notification and Work Plan (Work Plan) was submitted to the NC DEQ on December 7, 2015 and was approved on January 28, 2016. The approved Work Plan stated that samples from groundwater monitoring wells MW-1 and MW-2 would be analyzed for the NC Appendix II list of constituents during the first semi-annual water quality monitoring event of 2016 and during subsequent events, MW-1 and MW-2 would be analyzed for NC Appendix I list of constituents plus detected NC Appendix II constituents. No additional NC Appendix II constituents were detected in the samples from MW-1 and MW-2 during the February 2016 event and therefore, future events will be analyzed for the NC Appendix I list of constituents. Benzene was detected in the sample from MW-6 at a concentration above the SWSL and NC 2L Standard during the July 2016 sampling event. Based on the July 2016 monitoring results, an Assessment Monitoring Notification and Work Plan Addendum (Addendum) was submitted to the NC DEQ on October 21, 2016 and was approved on October 31, 2016. The approved Addendum stated that assessment monitoring wells, AMW-1 and AMW-2, would be installed downgradient of MW-2 and MW-6, respectively. The Addendum also stated that samples from groundwater monitoring wells MW-6, AMW-1, and AMW-2 would be analyzed for the NC Appendix II list of constituents during the first semi-annual water quality monitoring event of 2017 and during subsequent events MW-6, AMW-1, and AMW-2 would be analyzed for NC Appendix I list of constituents plus detected NC Appendix II constituents. Assessment monitoring wells AMW-1 and AMW-2 were installed in December 2016 in accordance with the Addendum and sampled for the first time during the January 2017 event. In response to exceedances of groundwater standards of inorganic constituents, Golder submitted an Assessment Monitoring Work Plan Addendum 2 (Addendum 2) on November 8, 2019, which proposed sampling of existing piezometer P-3 for inorganic constituents over five years to establish background concentrations. The Addendum 2 was approved by the NC DEQ on November 14, 2019. Benzene was detected in the samples from MW-8, AMW-1, and AMW-2 at quantifiable concentrations above the NC 2L Standard during the January 2021 sampling event. Based on the January 2021 monitoring results, an Assessment Monitoring Work Plan Addendum 3 (Addendum 3) was submitted to the NC DEQ on March 26, 2021 and was approved on March 30, 2021. Addendum 3 stated that MW-8 would be sampled and analyzed for the NC Appendix II list of constituents during the second semi-annual water quality monitoring event of 2021 and that pore water samples (PWS-4, PWS-5, and PWS-6) would be collected annually from downgradient of wells MW-8, AMW-1, and AMW-2 and analyzed for NC Appendix I VOCs. The pore water sampling locations are shown on Figure 1. As part of ongoing remedial efforts, High Point C&D Landfill completed final soil cap construction for Phases 1 and 2 in July 2017. Additionally, 14 in waste passive landfill gas vents were installed, some of which are located in proximity to areas of known VOC groundwater contamination at groundwater monitoring wells MW-2, MW-6, and MW-8. Based on average horizontal groundwater %%%I) GOLDER 2 September 21, 2022 GL2013788122 flow rates for the facility which are relatively low, it could take more than 25 years for groundwater located below the landfill gas vents to travel to the impacted groundwater monitoring wells. High Point C&D Landfill is continuing to evaluate the effects of the recently installed soil cap and landfill gas vents on groundwater quality along the western waste boundary at MW-2, MW-6, and MW-8 prior to evaluating any additional remedies. 1.3 Hydrogeologic Setting Geologically, the facility is located within the Carolina Slate Belt of the Piedmont Physiographic Province of North Carolina (NCGS, 1985). Generally, the Carolina Slate Belt consists of Late Proterozoic to Cambrian volcanic and greenschist-facies metasedimentary rocks intruded by plutonic suites (Butler and Secor, 1991). The site geology is characterized by a regional -scale felsic intrusive complex, which consists mainly of white to gray, fine- to coarse -grained, massive to foliated metamorphosed granitic rock. The region is characterized by regional and small-scale Mesozoic diabase dikes. The uppermost groundwater beneath the facility is present in a shallow, unconfined aquifer comprised of saprolite, partially weathered rock (PWR), and granitic bedrock. Groundwater occurs at depths of approximately 25 feet below grade along the northern upgradient side of the waste disposal area, and at a depth of less than 10 feet below grade along the perimeter downgradient boundary. Depth to water measurements, obtained during the July 2022 monitoring event and summarized in Table 1, were used to prepare a groundwater surface contour map presented on Figure 1. Surface water and groundwater at the site generally flows south to southwest towards a tributary of Richland Creek. Richland Creek is approximately 1300 feet south of the site and flows to the Deep River, which is approximately 0.5 miles from the site. Groundwater beneath the site flows in three distinguishable and vertically interconnected hydrogeologic units; saprolite, PWR, and bedrock. The groundwater surface contour map and interpreted flow directions are consistent with previously submitted interpretations for this facility. Based on the July 5, 2022, groundwater contour map, the average 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 0.043 feet per foot (Table 2). Groundwater velocities were calculated using a hydraulic conductivity of 1.37E-05, which is the geometric mean of the hydraulic conductivities for each of the hydrogeologic units present at the facility. The estimated effective porosity of the shallow aquifer is expected to range from 0.20 (saprolite) to 0.09 (fractured rock). The effective porosity of the fractured rock was used in calculations to provide a conservative estimate of groundwater flow. Using the above values, the estimated rate of groundwater flow for the uppermost aquifer beneath the facility was calculated using the following modified Darcy equation: Vgw = Ki/ne where Vgw = average linear velocity (feet/year), K = hydraulic conductivity (feet/year), i = horizontal hydraulic gradient, and ne = effective porosity. The average estimated linear groundwater flow velocity under the waste management unit is approximately 6.7 feet/year, which is generally consistent with previous estimates (Table 2). The range of groundwater flow is expected to vary depending on the hydrogeologic unit in which it occurs. The linear velocity equation above makes the simplified assumptions of a homogeneous %N%I) GOLDER September 21, 2022 GL2013788122 and isotropic aquifer. Therefore, this equation represents a likely average value for the uppermost aquifer and does not account for heterogeneous and/or anisotropic conditions that may be present in the uppermost aquifer at the facility. 2.0 FIELD PROGRAM, MONITORING RESULTS AND DISCUSSION Field activities conducted for the July 2022 sampling event are discussed in the following sections. 2.1 Visual inspection Program In order to ensure that a potential release is detected at the earliest possible time, the visual inspection program is used by Golder personnel at the High Point C&D Landfill. This program includes physical indicators such as potential water table mounding beneath the waste management unit, physical examination of any stresses in biological communities, visible signs of leachate migration (i.e., leachate seeps), unexplained changes in soil characteristics, and any other change to the environment due to the waste management unit. During this compliance monitoring event no physical indicators of a potential release were observed in the vicinity of the waste management areas. 2.2 Well Network and Groundwater Elevation Measurements The current approved network of groundwater monitoring wells at the facility consists of eight compliance monitoring wells and two assessment monitoring wells. Monitoring well construction information is summarized on Table 3 and the well locations are shown on Figure 1. The well locations were selected to yield groundwater samples representative of the conditions in the uppermost aquifer underlying the facility, and to monitor for potential releases from the landfill unit. Two upstream (SW-1 and SW-3) and four downstream (SW-2, SW-4, SW-3, and SW-6) surface water monitoring points are also monitored and are shown on Figure 1. Monitoring well MW-1 is the facility's background well and is located hydraulically upgradient of the waste disposal area. Monitoring wells MW-2, MW-3, MW-4S, MW-5, MW-6, MW-7S, MW-8, AMW-1, and AMW-2, are located downgradient of the waste disposal area and represent the facility's downgradient wells. Piezometer P-3 is located upgradient and is currently being sampled during semi-annual water quality monitoring events to establish inorganic background concentrations. Depth -to -water measurements were recorded to the nearest 0.01 foot prior to initiating groundwater purging and sampling activities. The respective groundwater level elevations for this event are presented in Table 1 along with historical water level data. As presented, the data indicate that the hydraulic head level in the uppermost aquifer beneath the facility is fairly consistent, with temporal variation from the long-term average limited to approximately 5 feet (plus or minus). As expected, the range in fluctuation appears to be greater in the upgradient well MW-1, as this well is located in a groundwater recharge area. The range in fluctuation in downgradient compliance wells, which are located near groundwater discharge areas, is much less, presumably due to the stabilizing effect of the hydraulic discharge boundary. 2.3 July 2022 Groundwater and Surface Water Monitoring Event Personnel from Golder visited the facility on July 5 - 7, 2022 to purge and sample monitoring wells MW-1, MW-2, MW-3, MW-4S, MW-5, MW-6, MW-7S, MW-8, AMW-1, AMW-2, and piezometer P-3; sample pore water samples PWS-4, PWS-5, and PWS-6; and to sample surface water monitoring points SW-1, SW-2, SW-3, SW-4, SW-5, and SW-6. Pore water sample locations PWS-4 and %N%I) GOLDER September 21, 2022 GL2013788122 PWS-5 did not encounter the water table and were not sampled. Surface water locations SW-1 and SW-2 were dry and samples were not collected. Depth -to -water measurements were obtained from the network monitoring wells and additional wells (MW-4D and MW-7D) to the nearest 0.01 foot using an electronic water level indicator prior to purging the wells. Compliance and assessment monitoring wells were purged and sampled using low -flow sampling techniques from dedicated bladder pumps. Piezometer P-3 was purged and sampled using low - flow sampling techniques from a peristaltic pump. Measurements of temperature, pH, specific conductivity, dissolved oxygen (DO), oxidation-reduction potential (ORP), and turbidity were recorded on approximately 4- to 5-minute intervals during the purge, depending on the purge rate. In general, the purge rate was matched to the yield of the monitoring well, as determined by continuously monitoring the depth -to -water, not allowing the purge rate to exceed 200 milliliters per minute. Purging was continued until stabilization was indicated by the field parameters. Prior to sampling, the laboratory -supplied sample containers were prepared. Each sample container was labelled with the sample identification number, sampling personnel, date and time of sample collection, project name and number, and requested chemical analyses. The required groundwater samples were collected directly from the bladder pump discharge lines into the labelled, laboratory -supplied, pre -preserved sample containers after purging was completed based on stabilization of field parameters. The surface water samples were collected directly from the stream flow, by lowering the sample containers into the stream flow with the opening facing away from the current flow, taking care to prevent the overflow of the sample containers and to minimize sample -induced turbidity. Measurements of temperature, pH, specific conductivity, DO, ORP, and turbidity were recorded during the collection of the surface water samples. After collection, the samples were placed in a cooler on ice, under chain -of -custody control. Copies of the sampling logs are presented in Appendix A. Included in each log is a description of the sampling equipment, sampling location, sampling method, field observations, and field measurements. 2.4 Laboratory Analysis Program The July 5 - 7, 2022 groundwater and surface water samples were delivered via courier to Environmental Conservation Laboratories, Inc. (ENCO) of Cary, NC under chain -of -custody control for analysis. As presented, the July 2022 groundwater samples from MW-1, MW-2, MW-3, MW-4S, MW-5, MW-6, MW-7S, MW-8, AMW-1, and AMW-2 were analyzed for the NC Appendix I list of constituents plus the C&D indicator parameters specific to 15A NCAC 13B .544(a)(1)(D), tetrahydrofuran, and 1,4-dioxane. P-3 was analyzed for NC Appendix I metals plus mercury, manganese, and iron. The surface water samples SW-3, SW-4, SW-5, and SW-6 at the facility were analyzed for the NC Appendix I list of constituents plus tetrahydrofuran and 1,4-dioxane. Pore water sample PWS-6 was analyzed for NC Appendix I VOCs. The samples were received at the laboratory on July 8, 2022, in good condition and properly preserved. 3.0 LABORATORY AND FIELD QA/QC A field blank was collected by Golder personnel as part of the July 2022 sampling event. ENCO analyzed the field blank for the NC Appendix I list of constituents plus iron; manganese; mercury; 1,4-dioxane; and tetrahydrofuran. In addition to the field blank, a laboratory -prepared trip blank accompanied the volatile sample containers to and from the laboratory and was analyzed for NC Appendix I VOCs plus 1,4-dioxane and tetrahydrofuran. ENCO analyzed the laboratory blanks for %N%I) GOLDER September 21, 2022 GL2013788122 the same parameters analyzed for the groundwater samples. A review of the laboratory data was performed by Golder personnel and is included in Appendix B. Based on data review performed by Golder, beryllium and manganese were detected at estimated concentrations in the field blank, toluene was detected at a quantifiable concentration in the trip blank, and chloride was detected at an estimated concentration in the laboratory method blank. Therefore; the concentrations for the following samples are considered blank -qualified: beryllium at P-3, toluene at MW-2, and chloride at MW-3 and MW-5. 4.0 DATA EVALUTION 4.1 North Carolina Groundwater and Surface Water Quality Standard Comparisons Analytical results and field parameters for the July 2022 groundwater samples are summarized in Tables 4 and 5 along with available historical data. As presented in Table 4, three NC Appendix I inorganic constituents were detected in groundwater samples at quantifiable concentrations above their applicable groundwater standards during the event. Barium was detected in the samples from MW-2 and MW-6 at quantifiable concentrations above the NC 2L Standard. Chromium was detected in MW-8 at quantifiable concentration above the NC 2L Standard. Cobalt was detected in the samples from MW-8, AMW-1, and AMW-2 at quantifiable concentrations above the NC 2L Standard. Cobalt was also detected at estimated concentrations above the NC 2L Standard in the samples from MW-2 and MW-6. As the concentrations are estimated (i.e., non -quantifiable) concentrations below the method reporting limits, per the 15A NCAC 02L .0202 (b)(1), no regulatory actions should be taken for estimated values below the reporting limits (a.k.a. PQLs) that are above groundwater standards. Indicator parameters iron, manganese, and total dissolved solids (TDS) were detected at quantifiable concentrations above their respective NC 2L Standards in samples from one or more downgradient wells during this event. As presented in previous reports and alternate source demonstrations (ASDs), the inorganic concentrations reported in the groundwater samples are generally within natural background concentrations. Additional analytical data are being collected from upgradient piezometer P-3 during semi-annual monitoring events to evaluate inorganic concentrations through the January 2024 event. Two NC Appendix I VOCs were detected at quantifiable concentrations above the NC 2L Standard in samples from one or more downgradient wells during the July 2022 event. Benzene was detected in the samples from MW-2, MW-6, MW-8, and AMW-2 at quantifiable concentrations above the NC 2L Standard. Vinyl chloride was detected at a quantifiable concentration above the NC 2L Standard in the sample from MW-8. Vinyl chloride was also detected at an estimated concentration above the NC 2L Standard in the sample from MW-7S. Additionally, 1,4-dioxane was detected at quantifiable concentrations above the NC 2L Standard in samples from one or more downgradient wells during the event. 1,4-dioxane was analyzed per the May 30, 2018, NC DEQ memorandum and is not part of the facility permit -required testing. Generally, concentrations of VOCs are consistent with historical data. Per Addendum 3, pore water samples (PWS-4, PWS-5, and PWS-6) are typically collected from beneath the stream bed downgradient of wells MW-8, AMW-1, and AMW-2. The locations are shown of Figure 1. The samples are typically analyzed for NC Appendix I VOCs. The analytical and field parameters are summarized on Tables 6 and 7. PWS-4 and PWS-5 did not encounter the %%%I) GOLDER September 21, 2022 GL2013788122 water table during the July 2022 event and samples were not collected. No VOCs were detected in the pore water sample from PWS-6 during the event. As stated in Section 1.2, a final soil cap was completed for Phases 1 and 2 and 14 gas vents were installed into the landfill in July 2017. Due to the relatively low flow rates downgradient of the landfill, the effects of these improvements on water quality are still being evaluated. Nested well pair MW-4S and MW-4D are located near the western facility boundary southwest of the C&D landfill. Based on the data presented in Table 2, an upward component of groundwater flow is measured at MW-4S/D. Based on an evaluation of the elevation of an unnamed tributary to Richland Creek adjacent to MW-4S/D and water table elevation in MW-4S, the unnamed tributary is a receiving stream and above standard concentrations of VOCs detected at MW-2, MW-6, MW-8, AMW-1, and AMW-2 are unlikely to extend off site, which is further supported by the pore water sampling results. Analytical results and field parameters for the July 2022 surface water samples are summarized in Tables 8 and 9 along with available historical data. Cobalt was detected at a quantifiable concentration above the applicable surface water standard from downgradient surface water point SW-5 during the July 2022 event, as it has been during previous events. A literature search of cobalt concentrations in stream sediment for Guilford County, NC was conducted to provide evidence that the source of cobalt in the sample from SW-5 is naturally occurring. The United States Geological Survey (USGS) National Geochemical Survey Database is a collection of stream sediment data from across the US. This database was used to locate 14 stream sediment samples collected between 1 to 20 miles from the High Point C&D Landfill, which are summarized below. Range of Cobalt Concentrations Mean Cobalt Concentration 111 111 parts per billion (ppb)111 ••• These concentrations of cobalt in sediment would account for the concentrations detected in the sample from SW-5. A summary table of the data used from the National Geochemical Survey Database is provided in Appendix C. Based on the stream sediment metals data presented above, the cobalt concentrations reported in the sample from SW-5 are within natural background concentrations. Therefore, future cobalt results will continue to be monitored, and no further action is warranted at this time. No NC Appendix I VOCs were detected at quantifiable concentrations above surface water standards in samples from the surface water monitoring locations during the event. 1,4-dioxane was detected at quantifiable concentrations above the NC 2L Standard in samples from upstream and downstream surface water samples. 5.0 CONCLUSIONS During the July 2022 event, Golder sampled piezometer P-3, which is located upgradient of the waste unit, to collect additional inorganic constituent data to further evaluate concentrations of inorganic constituents recently detected in samples from downgradient wells. This was the seventh of ten planned sampling events. The facility will continue monitoring in accordance with the requirements of the Assessment Monitoring Program as outlined in Title 15A NCAC 13B.0545, the Work Plan, and Addendums. The next groundwater monitoring event is tentatively scheduled for January 2023. %%%I) GOLDER September 21, 2022 6.0 REFERENCES GL2013788122 Babb & Associates, P.A., 2020, Notification of Pre -Regulatory Waste Disposal Site; Former Jackson Lake Road Landfill, High Point, Guilford County, North Carolina.

Results for these procedures apply only to the samples as submitted. The analytical results contained in this report are in compliance with NELAC standards, except as noted in the project narrative if applicable. This report shall not be reproduced except in full, without the written approval of the Laboratory. This report contains only those analyses performed by Environmental Conservation Laboratories. Unless otherwise noted, all analyses were performed at ENCO Cary. Data from outside organizations will be reported under separate cover. If you have any questions or require further information, please do not hesitate to contact me. Sincerely, Amanda L.

(G0007) Project: GFL Env - High Point, LLC Lab ID: CF09470 Overview (� �Eo www.encolabs.com Environmental Conservation Laboratories, Inc. (ENCO) analyzed all submitted samples in accordance with the methods referenced in the laboratory report. Any particular difficulties encountered during sample handling by ENCO are discussed in the QC Remarks section below. Quality Control Samples The 8260D spike recoveries for 1, 1 -Dichloroethane and Chloroform were outside control limits for the MS and/or MSD samples, the precision between duplicate spikes of 1,4-Dichlorobenzene exceeded acceptance criteria. The QC batches were approved based on acceptable LCS recovery of these analytes. The spike recoveries for Barium, Iron, and Manganese were outside control limits for the MS, MSD, and/or Post Digestion spike samples. The QC batches were approved based on acceptable LCS recovery of these elements. The spike recoveries for Alkalinity, Chloride, and Sulfate were outside control limits for the MS and MSD samples, the precision between duplicate spikes of Chloride and Sulfate exceeded acceptance criteria. The QC batches were approved based on acceptable LCS recovery of these analytes. Quality Control Remarks No Comments Other Comments Acetone, a common laboratory contaminant, was detected in samples 4116-MW2, 4116-MW6, and 4116-AMW2 Methylene chloride, a common laboratory contaminant, was detected in sample 4116-MW8. The reported detection of Toluene in the 8260D analyses in the Trip Blank was investigated. The contamination is suspected to be from the Laboratory, this has been corrected. All samples received under this work order arrived in acceptable conditions. The samples were not checked for chlorine, as it is not required. The analytical data presented in this report are consistent with the methods as referenced in the analytical report. Any exceptions or deviations are noted in the QC remarks section of this narrative or in the Flags/Notes and Definitions section of the report.

I Page 67 Of 72 (� �Eo www.encolabs.com FLAGS/NOTES AND DEFINITIONS B The analyte was detected in the associated method blank. D The sample was analyzed at dilution. J The reported value is between the laboratory method detection limit (MDL) and the laboratory method reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable. U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. E The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is based on the low point of the calibration curve, when applicable, sample preparation factor, dilution factor, and, in the case of soil samples, moisture content. PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL. N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater confidence) to make a "tentative identification". P Greater than 25% concentration difference was observed between the primary and secondary GC column. The lower concentration is reported. [CALC] Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses. 0-01 This compound is a common laboratory contaminant. QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable LCS recovery. QM-08 Post -digestion spike did not meet method requirements due to confirmed matrix effects (dilution test). QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits.

JS Trip, field and/or equipment, and laboratory blank results have all been reported. All detects for blanks are listed below by constituent. All laboratory method blanks, if any, have been 'flagged' with a 'B' where detected in other samples as appropriate and a laboratory narrative was provided. If the sample was flagged by the laboratory and is not within 5X of the concentration in the blank (or 1 OX for commonly detected laboratory contaminants -acetone, methylene chloride and phthalates), list below with explanation if flags should be removed. If flags need to be added for samples, also list below. ➢ Trip Blank: Toluene @ 2.1 ug/L ➢ Field Blank: Beryllium @ 0.229 ug/L (J) Manganese @ 1.65 ug/L (J) JS It is clear from the laboratory report that samples have or have not been diluted during analysis, and if the samples have been diluted, the result is reported as a multiple of the dilution (e.g., a sample diluted 1 Ox resulting in an analytical detection of 1.0 should be reported as 10). Those that have been diluted are listed below with the dilution factor. ➢ Antimony and Thallium — all wells and SW (2x) ➢ 1,4-Dioxane — MW-6 (10x); AMW-2 (5x) ➢ Total Alkalinity as CaCO3 — AMW-2, MW-7S, (5x); MW-2, MW-6, MW-8, AMWA (10x) ➢ Chloride: MW-8, MW-2, AMW-2 (3x); MW-6 (5x) ➢ Sulfate: MW-8 (2x), MWA (4x) ➢ Total Dissolved Solids: MW-2, MW-6 (2x) .is The report provides the reporting limit for each constituent. JS The results were reported at or below their proper reporting limits (i.e., MDLs with PQLs reported). Those that are not reported correctly are listed below (by constituent) with the proper reporting limit listed beside them. State if the reporting limit error is due to dilution.
