Semi-Annual Water Quality Monitoring Report-October 2023 Cherokee County Lined Landfill Page 1 Introduction On behalf of Cherokee County, Municipal Engineering, Inc. is pleased to present this Semi-Annual Water Quality Monitoring Report for an event performed at the Cherokee County Lined Landfill (SWS Permit No. 20-02) on October 3,4 &6, 2023. The site is located at 10160 US Hwy 19/74/129, Marble, Cherokee County, North Carolina. North Carolina Department of Environmental Quality (NCDEQ) Solid Waste Section (SWS) Rules at Title 15A, North Carolina Administrative Code, Subchapter 13B (15A NCAC 13B) .1630 through .1637 require that Cherokee County provide this monitoring report to the SWS on a semi-annual basis. This report contains a description of sampling procedures, field and laboratory results, ground and surface water characterization results, and discussion of an assessment downgradient of MW-4, submitted in general accordance with 15A NCAC 13B.1632(i), the SWS Environmental Monitoring Report Form and SWS memorandums. Detection tables, a potentiometric map, field parameters, laboratory analytical reports with quality assurance/quality control data, chains-of-custody (COC) are also included in this report. Benzene and cobalt were detected above their respective NC Groundwater Quality Standards located at 15A NCAC 2L .0200 (2L Standard) in samples collected from MW-4 and MW-7, respectively. Various constituents were detected in raw leachate samples, including 1,4-dioxane. No constituents were detected above allowable Standards in surface water samples collected from the Valley River, which serves as the local discharge feature. Water samples were also collected and tested for Per and Polyfluoroalkyl Substances (PFAS) from monitor well locations MW-4, MW-6S, and the raw leachate. PFAS constituents were detected in each sample. Background The site operates as an active lined municipal solid waste landfill (MSWLF) which encompasses approximately 17 acres. Contiguous Phases (1, 2 & 5 with vertical expansions Phase 3 & 4) make up this lined landfill; therefore, they are combined and treated as a single unit in this report. Water quality monitoring has been consistently performed at least semi-annually prior to commencing operations in 2000. The site has been under assessment monitoring since February 2008 in response to detections of volatile organic compound (VOC) in samples collected from MW-6S, MW-6D and MW-7. Assessment monitoring of MW-4 was also initiated in October 2022 in response to observed impacts. MESCO requested that 1,4-Dioxane be only targeted at samples MW-4 and leachate on April 14, 2023 (DIN:1792187) which was approved by the SWS on May 11, 2023 (DIN:1795180). Sampling Locations The currently approved water quality monitoring network includes 18 locations; thirteen downgradient monitoring wells (MW-2, MW-3, MW-4, MW-5, MW-6S, MW-6D, MW-7, MW-8, MW-9, P-17, P-18, P-19 and P-21) an upgradient background monitoring well (MW-BG), influent to a wastewater holding lagoon (LEACHATE), three downstream surface water locations (SW-2, SW-4, SW-5) and one upstream surface water point (SW-1). Quality control measures included analysis of an equipment blank (EB) and field blank (FB). All locations listed in the WQMP were sampled during this event. Semi-Annual Water Quality Monitoring Report-October 2023 Cherokee County Lined Landfill Page 2 Water quality monitoring locations are depicted on Figure 1. A summary detailing the construction of the water quality monitoring wells is presented on Table 1. Sampling and Laboratory Procedures Sampling was conducted utilizing portable methodology outlined in the NCDEQ SWS guidance document Solid Waste Section Guidelines for Groundwater, Soil, and Surface Water Sampling revised April 2008. The function and integrity of all monitoring locations were visually evaluated with a few improvements made as documented on Table 2. The depth to water in each well was electronically gaged prior to purging to quantify the static water level elevation. Bailing or submersible pumping was used to purge the wells a minimum of three times the volume of standing water in the well or until dry. Samples were collected up to 24 hours following purging. Surface water samples were dipped from the Valley River at previously designated locations. Samples were then placed into laboratory-prepared, pre- preserved containers. Samples were kept on ice and transported to a NC-certified laboratory under proper chain of custody (C-O-C) protocol within the specified hold times for each analysis. Field Parameter Data Stabilized field parameters were recorded prior to water sample collection, which included pH, specific conductance, temperature, hardness (for surface water samples only) and turbidity. A summary of the field parameter data is presented in Table 3 and field data sheets are in Appendix A. In general field parameter results remain consistent with previously reported events. Laboratory Results Pace Analytical Services, LLC (PACE) network of labs (NC Certs. #12, 40375, 667) performed all the laboratory analysis except for leachate BOD which was tested by Earth Environmental (NC Cert. #352). All groundwater samples were tested for constituents listed in 40 CFR 258 Appendix I, mercury, 1.4- dioxane and tetrahydrofuran except for MW-5. Pace reportedly misplaced the VOC samples collected from MW-5. Surface waters were tested for parameters listed in Appendix I, 1,4-dioxane and tetrahydrofuran. The leachate samples were tested for the SWS required list of parameters and low level 1,4-dioxane. Additionally, 3 groundwater wells, the lagoon leachate and the EB were tested for 40 PFAS compounds using draft EPA Method 1633. A sampling and analysis table summarizing the locations, targeted constituents and methods is presented as Table 4. Laboratory results and C-O-Cs are presented in Appendix B. Water samples were analyzed to the laboratory-established Method Detection Limits (MDL) and any value between the MDL and laboratory-established Reporting Limit (RL) is qualified by the laboratory as with a "J" which indicates an estimated concentration. "J-qualified" concentrations are considered non- quantifiable and discretion should be made prior to making decisions based on a value that the laboratory considers an estimate. Table 5 summarizes constituents detected in groundwater and QC samples compared to the 2L Standards effective April 1, 2022. Detected concentrations were also compared to the Maximum Contaminant Level (MCL) commonly referenced as the Federal “Drinking Water Standard” which are not recognized by NCDEQ as compliance Standards for these particular samples. Table 6 lists the constituents detected in surface water samples compared to values in the current version of the Division of Water Resources (DWR) Surface Water Quality Tables. Figure 1 shows the spatial Semi-Annual Water Quality Monitoring Report-October 2023 Cherokee County Lined Landfill Page 3 distribution of the constituents detected in excess of established compliance Standards. Table 7 summarizes the sample locations where PFAS constituents were detected. It should be noted that there are no compliance Standards currently established for PFAS constituents applicable to groundwater or surface waters in North Carolina. Quality Control Samples A low “J” qualified concentration of copper was detected in the EB sample Although the artifact contaminant was identified, MESCO believes the validity of the data-set is not affected since the concentration of copper was detected at just above the MDL. No other constituents were detected in either the EB or FB. Groundwater Samples Above Standards Metals Cobalt was only detected in sample MW-7 (32.8 ug/L) above its 2L Standard (1.0 ug/L). This is a significant change from the previous monitoring event where 6 additional locations reported the detection of cobalt above the 2L Standard. VOCs Sample MW-4 contained concentrations of benzene at 2.4 ug/L, above its respective 2L Standards of 1.0 ug/L. Surface Water Samples Above Standards No constituents were detected in surface water samples above allowable Standards. Leachate Samples Quantifiable concentrations of 2 metals and 1 VOC were detected in the raw leachate samples (LEACHATE) collected from the inlet to the lined holding lagoon. The BOD and COD levels were low and BOD/COD ratio (0.09) was high compared to typical domestic wastewater. BOD/COD ratio above 0.5 may indicate that the majority of organic matter is easily treated biologically1. PFAS Each of the 3 groundwater samples contained quantifiable concentrations of between 10 and 16 PFAS constituents out of 40. PFAS was found in all groundwater samples collected downgradient of this unit. The highest concentrations for a PFAS constituent were for PFHxA, detected in 2 of the 3 wells at concentrations ranging from 170 ng/L in MW-4 nanograms per liter (ng/L) to 310 ng/L in MW-7. The leachate sample reported the detection of 19 PFAS constituents, the highest of which was for the constituent 5:3FTCA. Individual PFAS constituents’ concentrations detected in groundwater, and the leachate sample are summarized in Table 7. https://cgi.tu-harburg.de/~awwweb/wbt/emwater/lessons/lesson_a1/lm_pg_1068.html Semi-Annual Water Quality Monitoring Report-October 2023 Cherokee County Lined Landfill Page 4 Groundwater and Surface Water Characterization A potentiometric map from groundwater elevations of the uppermost aquifer recorded during this event is shown on Figure 1. Groundwater flow rates and directions were calculated and are included on Table 8. Groundwater flows in a general southerly direction towards the Valley River discharge feature with rates ranging from about 16 feet/year (MW-BG) to 1,781 feet/year (MW-5), averaging approximately 295 feet/year. The flow directions and gradients are generally consistent with historical observations. The Valley River was visually observed to have moderate volume, moderate flow and low turbidity which is typical for the Fall season. Findings During this event all detections were within their own respective identified. range with the exception of benzene in samples from MW-4. Cobalt was only detected above the allowable 2L Standard in MW-7. The source of metals observed in MW-7 are believed to originate from dissolution of sediment entrained in the sample containers. Metals, including cobalt, are naturally inherent in the groundwater at the site with several lines of substantiating evidenced contained in an ASD-Total Metals drafted by MESCO dated July 26, 2017. The NC SWS concurred that metals may originate from erosion of natural deposits, but would not recognize the background concentrations since turbidity values were absent. An ASD -Addendum Workplan/Timeline-Metals was approved by the SWS and data continues to be collected to determine the natural background concentrations. An ASD-Add will be drafted if the data supports this approach. In the interim, it's understood that assessment monitoring in response to observed metal exceedances, in and of themselves, will not be self-implemented. The lack of VOCs in concentrations in excess of applicable standards in samples collected from shallow wells P-17, P-18, P-19, and P-21 during this event continues to support the assertion that the horizontal and vertical extent of VOC migration identified south of the landfill remains within the compliance boundary. There are no potential downgradient groundwater receptors between the landfill and the Valley River discharge feature. Surface water monitoring results indicate the discharge feature also remains unimpaired. The source of VOCs as observed in sample MW-4 is likely evidence of a leachate release. Cherokee County self-implemented assessment activities per Rule 15A NCAC 13B .1634. in response to previous detections of contaminates (benzene, 1,4-dioxane, cobalt) in May 2023. A temporary well (HAB-1), located downgradient of MW-4 did not contain benzene or 1,4-dioxane, however cobalt was detected slightly above the 2L but significantly lower than MW-4. The lack of VOCs, suggests the impacts to the uppermost aquifer have not migrated to the Valley River discharge feature which is within the compliance boundary. No further assessment activities or corrective actions are recommended at this time. The detection of PFAS was not unanticipated due to the prevalence of PFAS in the environment as documented in literature. Closing Semi-Annual water quality monitoring is planned to continue in the Spring of 2024.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPAMethod 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. TNI - The NELAC Institute. ANALYTE QUALIFIERS Sample was diluted due to the presence of high levels of non-target analytes or other matrix interference.D3 Analysis conducted outside the EPA method holding time.H1 Sample was received or analysis requested beyond the recognized method holding time.H3 This analyte exceeded secondary source verification criteria high for the initial calibration. The reported results should be considered an estimated value.IH Analyte detected below the reporting limit, therefore result is an estimate. This qualifier is also used for all TICs.J Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.M1 RPD value was outside control limits.R1 The continuing calibration verification was below the method acceptance limit. The analyte was not detected in theassociated samples and the sensitivity of the instrument was verified with a reporting limit check standard.v2 The continuing calibration verification was below the method acceptance limit. Any detection for the analyte in the associated samples may have low bias.v3 REPORT OF LABORATORY ANALYSIS This report shall not be reproduced, except in full, without the written consent of Pace Analytical Services, LLC.Date: 10/25/2023 09:40 AM Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 Page 49 of 56 #=CR# QUALITY CONTROL DATA CROSS REFERENCE TABLE Pace Project No.: Project: 92692736 CHEROKEE LINED MSWLF Lab ID Sample ID QC Batch Method QC Batch Analytical Method Analytical Batch 92692736001 958938 958947MW-BG EPA 3010 EPA 6010 92692736002 958938 958947MW-2 EPA 3010 EPA 6010 92692736003 958938 958947MW-3 EPA 3010 EPA 6010 92692736004 958938 958947MW-5 EPA 3010 EPA 6010 92692736005 958938 958947MW-6S EPA 3010 EPA 6010 92692736006 958938 958947MW-6D EPA 3010 EPA 6010 92692736007 958938 958947MW-7 EPA 3010 EPA 6010 92692736008 958938 958947MW-8 EPA 3010 EPA 6010 92692736009 958938 958947MW-9 EPA 3010 EPA 6010 92692736010 958938 958947P-17 EPA 3010 EPA 6010 92692736011 958938 958947P-18 EPA 3010 EPA 6010 92692736012 958938 958947MW-4 EPA 3010 EPA 6010 92692736013 958938 958947P-19 EPA 3010 EPA 6010 92692736014 958938 958947P-21 EPA 3010 EPA 6010 92692736015 958938 958947LEACHATEEPA 3010 EPA 6010 92692736001 960352 960427MW-BG EPA 7470 EPA 7470 92692736002 960352 960427MW-2 EPA 7470 EPA 7470 92692736003 960352 960427MW-3 EPA 7470 EPA 7470 92692736004 960352 960427MW-5 EPA 7470 EPA 7470 92692736005 960352 960427MW-6S EPA 7470 EPA 7470 92692736006 960352 960427MW-6D EPA 7470 EPA 7470 92692736007 960352 960427MW-7 EPA 7470 EPA 7470 92692736008 960352 960427MW-8 EPA 7470 EPA 7470 92692736009 960352 960427MW-9 EPA 7470 EPA 7470 92692736010 960352 960427P-17 EPA 7470 EPA 7470 92692736011 960352 960427P-18 EPA 7470 EPA 7470 92692736012 960352 960427MW-4 EPA 7470 EPA 7470 92692736013 960352 960427P-19 EPA 7470 EPA 7470 92692736014 960352 960427P-21 EPA 7470 EPA 7470 92692736015 960352 960427LEACHATEEPA 7470 EPA 7470 92692736012 2155244 2155244MW-4 8260D-SIM EPA 8260D by SIM 92692736015 2152651 2152651LEACHATE8260D-SIM EPA 8260D by SIM 92692736001 805863MW-BG EPA 8260D 92692736002 805863MW-2 EPA 8260D 92692736003 805863MW-3 EPA 8260D 92692736005 805863MW-6S EPA 8260D 92692736006 805863MW-6D EPA 8260D 92692736007 805863MW-7 EPA 8260D 92692736008 805863MW-8 EPA 8260D 92692736009 805863MW-9 EPA 8260D 92692736010 805863P-17 EPA 8260D 92692736011 805863P-18 EPA 8260D 92692736012 805863MW-4 EPA 8260D 92692736013 805863P-19 EPA 8260D 92692736014 805863P-21 EPA 8260D 92692736015 805863LEACHATEEPA 8260D REPORT OF LABORATORY ANALYSIS This report shall not be reproduced, except in full, without the written consent of Pace Analytical Services, LLC.Date: 10/25/2023 09:40 AM Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 Page 50 of 56 #=CR# QUALITY CONTROL DATA CROSS REFERENCE TABLE Pace Project No.: Project: 92692736 CHEROKEE LINED MSWLF Lab ID Sample ID QC Batch Method QC Batch Analytical Method Analytical Batch 92692736015 806052LEACHATESM 4500-S2D-2011 92692736015 807870 808140LEACHATEEPA 365.1 Rev 2.0 1993 EPA 365.1 Rev 2.0 1993 92692736015 807436 807722LEACHATESM 5220D-2011 SM 5220D-2011 REPORT OF LABORATORY ANALYSIS This report shall not be reproduced, except in full, without the written consent of Pace Analytical Services, LLC.Date: 10/25/2023 09:40 AM Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 Page 51 of 56 Page 52 of 56 Page 53 of 56 Page 54 of 56 Page 55 of 56 Page 56 of 56 #=CL# October 26, 2023 LIMS USE: FR - JONATHAN PFOHL LIMS OBJECT ID: 92693361 92693361 Project: Pace Project No.: RE: Mr. Jonathan Pfohl Municipal Engineering Services, Inc. 68 Shipwash Dr. Garner, NC 27529 CHEROKEE LF SW_BANKS Dear Mr. Pfohl: Enclosed are the analytical results for sample(s) received by the laboratory on October 13, 2023.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA Method 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. TNI - The NELAC Institute. ANALYTE QUALIFIERS Matrix spike recovery exceeded QC limits.
