This letter report presents the results of the semi-annual sampling event that was recently completed at the North Wake Closed Unlined Landfill (Site) and constitutes the first semi-annual sampling event for 2020. The groundwater monitoring network consists of the following wells: MW-11 (shallow background well), -11d (deep background well), -5R, -6, -6d, -7, -8, -8d, -9, -10, -10d, -22, -23, -23d, -24, -28, -28d, -29d, -30, -31, -31d, -32, -33, -34, -34d, -35, -36, -36d, TB-1a and TB-1a deep. Surface water sampling locations include SW-2, -3, -7, and -8. Field activities, sampling results for all wells and surface water locations, an evaluation of the groundwater corrective action effectiveness, and recommendations are discussed below. Field Activities Groundwater and surface water samples from the Site were collected on April 6-8, 2020. Monitoring well and surface water sample locations are shown on Figure 1. Construction details for each monitoring well are summarized in Table 1. Samples were collected from the monitoring wells by use of a peristaltic pump or disposable, laboratory decontaminated bailers. Groundwater elevations were measured at each well prior to sampling using an electronic water level indicator with an accuracy of 0.01 feet and are presented in Table 1. These groundwater elevations were used to construct potentiometric contours for this sampling event and are shown on Figure 1. The groundwater elevations and potentiometric contours were also used to estimate groundwater velocities at each well as presented in Table 2. After depth to groundwater was measured, three well volumes of water were removed from each well prior to sampling to provide fresh formation water within the well water column. Each well 0 WATER + ENVIRONMENT +TRANSPORTATION + ENERGY + FACILITIES Smith Ms. Jaclynne Drummond June 11, 2020 Page 2 volume and surface water sample were measured for pH, conductivity, temperature, turbidity, dissolved oxygen (DO), and oxidation-reduction potential (ORP) using a YSI-556 multi -parameter water quality meter and a HANNA HI 98703 turbidity meter. Wells that had elevated turbidity were allowed to stabilize prior to sample collection. The water quality measurements at the time of sample collection are provided in Table 3. Sampling Results All groundwater and surface water samples were analyzed by Pace Analytical Services, LLC (formerly Shealy Environmental Services, Inc.) located in West Columbia, South Carolina, for North Carolina Appendix I volatile organic compounds (VOCs) plus dichlorodifluoromethane and Appendix I metals plus mercury. Monitoring wells MW-22, -24, -30, -31, and TB-1a were not sampled during the April 2020 sampling event due to the low volume of groundwater in the wells and recharge rate. Samples from monitoring wells MW-5R, -6, -8, -9, -10, -11, -34, -34d, and -36 were analyzed for natural attenuation parameters (i.e. biochemical oxygen demand (BOD), chemical oxygen demand (COD), alkalinity, nitrate, chloride, sulfate, sulfide, total organic carbon (TOC), carbon dioxide, methane, ethane, ethene, ferrous iron, volatile fatty acids, and dissolved hydrogen) per the Corrective Action Plan (CAP) and CAP Addendum that were approved by the North Carolina Department of Environmental Quality (NCDEQ) - Solid Waste Section (SWS) in March 2010 and on June 10, 2019, respectively. Monitoring wells MW-5R, -34, and -34d were also analyzed for total iron, sodium, and total dissolved solids. The CAP and CAP Addendum are discussed below. In a letter dated May 29, 2018, the SWS stated that all groundwater and surface water samples collected from landfills be analyzed for 1,4-dioxane after July 1, 2018. On June 26, 2019, the SWS approved the removal of 1,4-dioxane from the sampling program for all monitoring wells and surface water locations, with the exceptions of MW-6, -8, and -9, due to two non -detect events (October 2018 and April 2019). Samples were collected from the wells requiring the 1,4-dioxane analysis during the April 2020 sampling event. Sample results are provided below. The analytical results were reported to the laboratory specific method detection limit (MDL) and are quantifiable at or below the laboratory limit of quantitation (LOQ). All monitoring wells for the Site had detections of analytes above the MDL but below the LOQs that were qualified as estimated or "J" flags. Methane was qualified with a "B" flag in samples collected from MW-6, -9, and -36, indicating that the analyte was detected in the method blank. Acetone, 2-butanone, COD, TOC, and methane were qualified with "D" flags in samples collected from MW-5R, indicating that the sample was analyzed at a dilution. In samples collected from MW-10, methane was also qualified with a "D" flag. BOD was qualified with a "7" flag in samples collected from MW-9, -10, -11, and -34d, indicating that the seed correction factor was above the method range and the results may be biased low. In samples 0 Smith Ms. Jaclynne Drummond June 11, 2020 Page 3 collected from MW-5R, BOD was qualified with a "75" flag, indicating that the sample became depleted. The reported result was computed using the greatest dilution and the least amount of sample. In samples collected from MW-5R and -11, acetic acid had "M3" and "M5" flags, indicating that the matrix spike duplicate sample recovery and sample recovery, respectively, were outside of laboratory control limits. Detections of acetic acid, butyric acid, hexanoic acid, pentanoic acid, propionic acid, and pyruvic acid also had "d" flags in samples collected from MW-5R, indicating that the analytes were analyzed at a dilution. The following list summarizes which analytes were detected above the LOQ at each sample location. Underlined analytes exceeded the 15A NCAC 02L .0202 (NC 2L) Groundwater Quality Standard, Interim Maximum Allowable Concentration (IMAC), or the 15A NCAC 02B (NC 2B) or North Carolina In - Stream Target Value Surface Water Quality Standard for Class C Waters. No "J" flag detections are listed. A complete summary of all detected and estimated concentrations from the March 2011 through the April 2020 sampling events is presented in Table 4. Laboratory data reports are provided in Appendix A.

In a letter dated March 22, 2012, the SWS approved the County's request to discontinue collecting samples from select wells for herbicide and pesticide analyses during the semi-annual spring sampling event. However, the SWS requested that MW-29d continue to be sampled for bis(2-ethylhexyl) phthalate during spring sampling events due to a detection from the March 2011 event. Bis(2-ethylhexyl) phthalate was detected above the NC 2L Standard (3 parts per billion (ppb)) at 28.5 ppb in samples collected from MW-29d during the April 2014 sampling event. A confirmatory sample collected from MW-29d during the November 2014 sampling event had an estimated detection of bis(2-ethylhexyl) phthalate at 4.61 ppb, which is above the NC 2L Standard. Bis(2-ethylhexyl) phthalate has not been detected above the laboratory MDL in samples collected from MW-29d since the November 2014 sampling event, except for estimated detections below the NC 2L Standard in samples collected during the April and October 2018 events, and the most recent April 2020 event. The concentration trend for bis(2-ethylhexyl) phthalate in MW-29d will continue to be evaluated. Equipment and trip blanks were analyzed for quality control. A duplicate sample was also collected for quality control. There were no detections in the equipment or trip blanks above the MDL. The duplicate sample, identified as DUP, was collected from TB-1a deep and had similar analyte concentrations as those detected in TB-1a deep, except for a detection of chromium above its NC 2L 00 Smith Ms. Jaclynne Drummond June 11, 2020 Page 8 Standard in the duplicate sample. Chromium was detected as an estimated concentration below the standard in the TB-1a deep parent sample. Table 5 presents a summary of all analytes detected during the April 2020 sampling event that exceeded the NC 2L or IMAC Standards. Samples were collected quarterly from January 2018 to April 2020 for a total of 10 events from the background monitoring wells, MW-11 and -11D, as part of an Alternate Source Demonstration (ASD) for the Site to generate non -turbid (i.e. less than 10 Nephelometric Turbidity Units (NTUs)) sample data for determining revised background and upper tolerance concentrations. The purpose of the ASD is to demonstrate that metals exceeding the NC 2L or IMAC Standards are naturally occurring and not related to a release from the landfill. An ASD report will be submitted to the SWS prior to the next semi-annual sampling event. As part of the ASD for the Site, filtered samples were collected from monitoring wells MW-5R, -7, -23, -28, -31d, -32, -33, -34, and -36 during the April 2020 sampling event due to elevated turbidity (i.e. greater than 10 NTUs). Total metals that exceeded the NC 2L or IMAC Standards from these wells were analyzed for dissolved metals to determine if turbidity was a contributing factor to total reported metals. Based on qualitative and quantitative evaluation of current and historic groundwater sampling data, the NC 2L or IMAC Standard metal exceedances from the April 2020 sampling event were determined to be indicative of naturally occurring background concentrations as opposed to a release from the landfill. Below is a summary of the dissolved metals exceedances. Wells with a "*' qualifier had a "J" flag detection for that analyte. Dissolved metal sample results are provided in Table 4 and the laboratory data report is provided in Appendix A. Cobalt: MW-5R and -7 Nickel: MW-5R Thallium: MW-5R* and -36 Vanadium: MW-31d Corrective Action via Air Sparging The SWS expressed concern in May 2008 that VOCs may be migrating beyond the Site property boundary and into Abbott's Creek based on detections above the NC 2L Standard in monitoring well MW-9. As a result, the SWS directed the County to install and sample groundwater monitoring wells, one shallow and one deep (i.e. MW-36 and -36d), downgradient of MW-9 to determine if VOCs may be migrating beyond the Site property boundary, possibly discharging into Abbott's Creek. Initial groundwater samples collected from MW-36 and -36d in December 2008 had detections of VOCs above NC 2L Standards. 0 Smith Ms. Jaclynne Drummond June 11, 2020 Page 9 Surface water sample locations SW-7 and -8, located on Abbott's Creek, were added to the semi- annual monitoring program in November 2008. Samples collected from SW-7 and -8 since being added to the monitoring program have never had VOCs detected above the NC 2B Surface Water Quality Standards. An Assessment of Corrective Measures Report was submitted to the SWS in accordance with the North Carolina Solid Waste Management Rule 15 NCAC 13B .1635 and approved in December 2009. The SWS approved the selected remedy of monitored natural attenuation paired with in situ remediation by air sparging to address groundwater contamination at the facility. A pilot test was conducted in July and August 2010 near MW-6 and -6d to evaluate the effectiveness of the air sparging remedy and to collect data for the full-scale system design in accordance with the CAP. The pilot test successfully reduced the concentrations of 1,1-dichloroethane and vinyl chloride to below their respective NC 2L Standard in MW-6d and vinyl chloride was not detected in samples collected from MW-6 during the October 2010 semi-annual sampling event. The full-scale system was installed in October 2011 and was operational in August 2012. The air sparging system consists of 15 shallow wells screened across saturated saprolite and partially weathered rock and 14 wells screened in the shallow fractured bedrock. In addition to the air sparging wells, the system also consists of an air compressor and control panel that are housed in a secured on -site control building. Routine inspections are performed on the system and a Field Inspection Log completed during each inspection is kept on file at the facility. The County installed a vacuum extraction system around the perimeter of the Site in January 2002 to prevent offsite migration of soil gas. The air sparging system was designed to work in tandem with the existing perimeter migration control system (PMCS) by recovering air and gas vapors produced by the air sparging system. Since previous work has indicated a relationship between the soil gas and the contaminated groundwater, the installation of the PMCS is likely to further reduce groundwater contaminant concentrations. As discussed in the approved CAP, the vacuum extraction system will be used in conjunction with the air sparging system to reduce VOCs in the bedrock and partially weathered rock between MW-9 and the MW-6 nested pair. As part of the corrective action effectiveness evaluation, contaminant concentration trends for monitoring wells MW-6, -6d, -9, -36, and -36d were evaluated. Total VOC concentration trends for each well are presented on Figures 2 through 6. Trend results for each well are discussed below. Figure 2 presents a total VOC concentration trend analysis for samples collected from MW-6. VOCs in MW-6 significantly decreased after January 2002 when the PMCS was operational and were not detected from November 2004 to April 2007. The total VOC concentration in MW-6 increased in May 2008 to 24 ppb compared to the November 2007 concentration of 14 ppb. The total VOC concentration in MW-6 showed a decreasing trend from May 2008 to April 2018 but has increased iD Smith Ms. Jaclynne Drummond June 11, 2020 Page 10 since the introduction of the 1,4-dioxane analysis in October 2018. The concentration of 1,4-dioxane in samples collected from MW-6 during the October 2018 and November 2019 sampling events was 26 ppb and 24 ppb, respectively. 1,4-Dioxane was also detected in samples collected from MW-6 during the April 2020 sampling event at a concentration of 10 ppb. Vinyl chloride has not been detected above the laboratory MDL in MW-6 since the April 2013 sampling event. Benzene detections in MW-6, which historically have exceeded the NC 2L Standard, have been below the laboratory MDL since April 2013 with the exception of the November 2014 sampling when it was detected slightly above the standard at 1.1 ppb and October 2018 when it was detected above the MDL at 0.61 ppb. The trend analysis for total VOC concentrations in MW-6d is presented on Figure 3. VOCs were not detected at MW-6d from December 2001 through November 2007. The increase in total VOCs from samples collected during the May 2008 sampling event is a result of reporting "J" flag detections as required by the SWS. VOC concentrations in MW-6d have been below the NC 2L Standards since the March 2011 sampling event and show a decreasing trend. Figure 4 presents a total VOC concentration trend analysis for samples collected from MW-9. Historically, MW-9 has had the highest concentration of VOCs compared to the other monitoring wells. VOCs were not detected above the NC 2L Standards in MW-9 from October 2012 through April 2015. There were "J" flag detections above the NC 2L Standard of 1,2-dichloroethane in samples collected from MW-9 during the October 2015 and April 2020 sampling events. Vinyl chloride was detected above the NC 2L Standard during the April 2016 sampling event, and from April 2019 to April 2020. Benzene was also detected above its NC 2L Standard during the April 2019 and 2020 sampling events. Additionally, 1,4-dioxane was detected above the standard during the April 2020 sampling event in samples collected from MW-9. The total VOC concentration trend is decreasing in samples collected from MW-9. Trend analyses for total VOC concentrations in MW-36 and -36d are presented on Figures 5 and 6, respectively. VOC concentrations in MW-36 have been below the NC 2L Standards since the April 2012 sampling event and have shown a decreasing trend since the air sparging system has been operational. No VOCs have been detected above the NC 2L Standards in MW-36d since the October 2015 sampling event. Total VOC concentrations in both monitoring wells will continue to be monitored and are expected to decrease while the air sparging system is operational. Additional groundwater samples were collected from MW-5R, -6, -8, -9, -10, -11, and -36 for evaluation of monitored natural attenuation parameters as part of the corrective action program as required by SWS guidelines. Geochemical results are presented in Table 6. The laboratory data for the additional parameters is included in Appendix A. 0 Smith Ms. Jaclynne Drummond June 11, 2020 Page 11 As discussed in the approved CAP, concentrations of some of the natural attenuation data from select wells indicates that environments are present which favor reductive dechlorination; notably, the concentrations of nitrate, ferrous iron, sulfate, and carbon dioxide. The following evidence indicates that one or more mechanisms of natural attenuation and/or reductive dechlorination may be occurring at the site: • VOC concentrations in contaminated wells continue to decline; • The ratio of parent to daughter compounds continues to decrease over time; • Nitrate, ferrous iron, sulfate, and carbon dioxide continue to be detected at concentrations favoring reductive dechlorination; and • Concentrations of cis-1,2-dichloroethene continue to be greater than dichloroethene isomers trans 1,2-dichloroethene and 1,1-dichloroethene. Corrective Action via In Situ Bioremediation Injection VOCs that exceed the NC 2L Standards, including benzene, 1,4-dichlorobenzene, 1,1-dichloroethane, methylene chloride, tetrachloroethene, trichloroethene, and vinyl chloride, have been detected in the area of MW-51R, -34, and -34d. MW-5R is located near the Site property line and the MW-34 cluster is located east of MW-5R on the adjacent parcel, more than 900 feet from the air sparging system. The VOC exceedances are likely from the migration of leachate from the Site into the surficial aquifer. In accordance with the CAP Addendum that was approved by the SWS on July 10, 2019, and an injection permit obtained from the Division of Water Quality— Underground Injection Control Program on July 24, 2019, an in situ enhanced anaerobic bioremediation (EAB) injection was completed by adding sodium lactate and emulsified vegetable oil (EVO) substrates through a biobarrier injection system in order to reduce total VOC concentrations at the property line. Sodium lactate and EVO enhance biologically reducing conditions that favor and support dechlorination of VOCs to non -toxic end products. On August 26-28, 2019, eight injection wells (i.e. NWIW-1 through -5) were installed upgradient of MW-51R, -35, and -34d, as shown on Figure 1. An initial injection of sodium lactate was completed on October 8-16, 2019. A total of 54,181 gallons of a 2.4 percent sodium lactate solution were injected. Post -sodium lactate injection samples were collected 1 month after the injection during the November 2019 semi-annual sampling event. Samples collected from monitoring wells MW-51R, -34, and -34d were analyzed for natural attenuation parameters, sodium, total iron, and total dissolved solids. Analytical results are summarized in Tables 4 and 6. The EVO injection was completed on November 18-30 and December 1-6, 2019, with a 3.3 percent solution of 98 percent LactOil® EVO formulation. A total of 80,751 gallons of the solution was injected. 0 Smith Ms. Jaclynne Drummond June 11, 2020 Page 12 The effectiveness of the EAB injection is currently being evaluated with quarterly sampling of MW-5R, -34, and -34d. The first and second quarterly sampling events were completed in February and April 2020, respectively. The third quarterly sampling event will be completed in August 2020. The fourth and final quarterly sampling event will be completed in during the fall 2020 semi-annual sampling event. Following the completion of the fourth quarterly sampling, CDM Smith will prepare an injection report for the SWS and the County. Recommendations The County will continue with the semi-annual assessment monitoring program. In addition to sampling for Appendix I metals plus mercury, Appendix I VOCs plus dichlorodifluoromethane, and the Appendix 11 constituent, bis(2-ethylhexyl) phthalate (sampled at MW-29d only during the spring sampling event), samples collected from MW-5R, -6, -8, -9, -10, -11, -34, -34d, and -36 will continue to be analyzed for natural attenuation parameters during the semi-annual events. MW-6, -8, and -9 will continue to be analyzed for 1,4-dioxane. The air sparging system will continue to operate and the effectiveness of the system will be re-evaluated after the next semi-annual sampling event in the fall of 2020.

MW-11 is a background well for the North Wake Unlined Landfill. 5. * - Field analysis performed using a HACH kit. 6. (--) - Not Measured 7.1 - Indicates the analytical result is an estimated concentration between the method detection limit and the limit of quantitation. 8. B - The analyte concentration detected in the method blank was greater than the method detection limit. 9. D, d - Analyzed as dilution. 10. UX - The compound was analyzed for, but not detected. 1 mL HNO3 was added to MW-6 for metals upon receipt to get the pH to <2. 11. (1) - BOD was measured following dilution and did not meet the oxygen depletion criterion of at least 2 mg/L. The elevated BOD concentrations are a result of laboratory error and were not used to evaluate natural attenuation for the April and November 2014 sampling events. 12. 1- The average BOD for MW-9, -10, -36, and -11 is lower than the valid range. 13. (-) Samples not collected and analyzed for the spring 2016 sampling event. 14. H - The analyte was analyzed outside of holding time. 15 (15) - 7 flag - The seed correction factor was above the method range. Results may be biased low. 16. (16) - 75 flag - The sample became depleted. The reported result was computed using the greatest dilution and the least amount of sample. 17. 117) - M3 flag - The matrix spike duplicate sample recovery was outside laboratory control limits. 18.

The sample receiving date is documented in the header information associated with each sample. All results listed in this report relate only to the samples that are contained within this report. Sample receipt, sample analysis, and data review have been performed in accordance with the most current approved NELAC standards, the Pace Analytical Services, LLC ("Pace") Quality Assurance Management Plan (QAMP), standard operating procedures (SOPS), and Pace policies. Any exceptions to the NELAC standards, the QAMP, SOPS or policies are qualified on the results page or discussed below. This PDF report has been revised to update the SVOA list for VD08043-001 (MW-29d) for bis(2- ethylhexyl)phthalate. All other data results are as reported in the original PDF report. VOA 8260D The continuing calibration verification (CCV) associated with analytical batch 50591 & 50636 recovered outside acceptance criteria, low biased, for Bromomethane (-22%). An LOQ standard was analyzed, and the target analyte was detected. Since the associated samples were non -detect, no corrective action was taken. Sample VD08043-016 (MW-5R) required a 5x dilution due to the nature of the sample matrix. The LOQ has been elevated to reflect the dilution. Sample VD08043-030 (MW-36d) was received with solid in the sample vial. The liquid was decanted from vial and then analyzed on instrument. BOD The seed correction factor was above the method range of 0.6 to 1.0. ENTER DATA: SCF = 1.17. Results are reported with a 7" data qualifier and may be biased low. The associated samples are: VD08043-002 (MW-6), VD08043-004 (MW-8), VD08043-005 (MW-10), VD08043-009 (MW-36), and VD08043-010 (MW-9). The seed correction factor was above the method range of 0.6 to 1.0. ENTER DATA: SCF = 1.16. Results are reported with a 7" data qualifier and may be biased low. The associated samples are: VD08043-014 (MW-14), VD08043-015 (MW-34d), VD08043-016 (MW-5R) and VD08043-017 (MW-11). Sample VD08043-016 (MW-5R) depleted out. All sample dilutions resulted in a final DO concentration of < 1.0 mg/L. The reported BOD/CBOD value is >82 mg/L, which was computed using the sample dilution volume having the lowest DO concentration (greatest dilution/least amount of sample). The sample dilutions performed were appropriate based on the dilutions noted in the "BOD/CBOD Pre -Established Dilutions" logbook (F-AD-115). The data has been flagged with a "5" qualifier.

Samples were analyzed with expired opening CCV standard, but with an good closing CCV standard. The opening and closing CCV passes all QC criteria, therefore the standard is still valid and the data has been reported.
