(CDM Smith), on behalf of Wake County (County), is submitting an electronic copy of the November 2021 semi-annual sampling event report. 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 second semi-annual sampling event for 2021. 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 November 9-11, 2021, except for MW-28, -28d, -33, and -35, which are sampled during the spring semi-annual sampling event, and MW-24, -30, and TB-1a, which were dry during the November 2021 sampling event. 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 on November 9, 2021, 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. Of WATER + ENVIRONMENT +TRANSPORTATION + ENERGY + FACILITIES Smith Ms. Jaclynne Drummond January 19, 2022 Page 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 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 (i.e., greater than 10 Nephelometric Turbidity Units) were allowed to stabilize prior to sample collection. The water quality measurements at the time of sample collection are provided in Table 3. Alternate Source Demonstration On August 17, 2020, CDM Smith submitted an Alternate Source Demonstration (ASD) for the Site on behalf of the County. The purpose of the ASD was to demonstrate that metals exceeding the 15A NCAC 02L .0202 (NC 2L) Groundwater Standards or Interim Maximum Allowable Concentrations (IMAC) are naturally occurring and not related to a release from the landfill. The ASD was prepared using analytical data from the background monitoring wells, MW-11 and -11D, that was collected on a quarterly basis from January 2018 to April 2020 to develop upper tolerance limits (UTLs) for specific analytes that historically exceeded their respective NC 2L Groundwater Standard or IMAC. Based on statistical analysis, a UTL of 6 parts per billion (ppb) was proposed for cobalt and a UTL of 23 ppb was proposed for vanadium. The North Carolina Department of Environmental Quality's (NCDEQ) Solid Waste Section (SWS) approved these proposed UTLs on August 17, 2020. Sampling Results All groundwater and surface water samples were analyzed by Pace Analytical Services, LLC located in West Columbia, South Carolina, for North Carolina Appendix I volatile organic compounds (VOCs) plus dichlorodifluoromethane and Appendix I metals plus mercury. Samples from monitoring wells MW-5R, -6, -8, -9, -10, -11, -34, -34d, and -36 were also analyzed for natural attenuation parameters (i.e., biochemical oxygen demand (BOD), chemical oxygen demand, alkalinity, nitrate, chloride, sulfate, sulfide, total organic carbon, 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 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 November 2021 sampling event. Sample results are provided below. 0 Smith Ms. Jaclynne Drummond January 19, 2022 Page 3 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 LOQ that were qualified as estimated or "J" flags. In samples collected from MW-5R and -9, detections of BOD were qualified with "1" flags, indicating that the average concentration was lower than the valid range. MW-5R and -9 also had detections of methane with "E" flags, indicating that the quantitation of the compound exceeded the calibration range. Additionally, MW-6 had an "E" flag detection of nitrate. In samples collected from MW-5R, -34, and -36, detections of chloride had "D" flags, indicating that the analyte was analyzed at a dilution greater than 1. MW-6 also had detections of nitrate and sulfate with "D" flags. Additionally, MW-9 had a detection of methane with a "D" flag. MW-11, -34, and -36 also had detections of nitrate with "D" flags. In samples collected from MW-6, a detection of nitrate had an "H" flag, indicating that the analyte was analyzed outside of hold time. MW-9 also had a detection of methane with an "H" flag. In samples collected from MW-9 and -10, detections of sulfate had "B" flags, indicating that the analyte was detected in the method blank. In samples collected from MW-34, a detection of iron had an "S" flag, indicating a matrix spike/matrix spike duplicate failure. The following list summarizes which analytes were detected above the LOQ at each sample location. Underlined analytes exceeded the NC 2L Groundwater Standard, IMAC, or UTL. There were no detections in the surface water samples that exceeded 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 November 2011 through the November 2021 sampling events is presented in Table 4. Laboratory data reports are provided in Appendix A.

It is likely that the recent and historic detections of chloroform in wells MW-6d, -24, -31, -31d, -32, TB-1a, and -1a deep are attributed to a release from a municipal water line in the Falls River development and are not related to a release from the Site. 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 Groundwater 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 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 Groundwater Standard in samples collected during the 2018 and April 2020 events. The concentration trend for bis(2-ethylhexyl) phthalate in MW-29d will continue to be evaluated. An equipment and three trip blanks were analyzed for quality control. A duplicate sample was also collected for quality control. Acetone was detected as an estimated concentration and chloroform was detected in the equipment blank below their respective NC 2L Groundwater Standards. There were no detections in the trip blanks above the MDLs. The duplicate sample, identified as DUP, was collected from MW-23d, and had similar analyte concentrations as those detected in MW-23d. Table 5 presents a summary of all analytes detected during the November 2021 sampling event that exceeded the NC 2L Groundwater Standards, IMACs, or UTLs. 0 Smith Ms. Jaclynne Drummond January 19, 2022 Page 8 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 Groundwater 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 Groundwater Standards. 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 Groundwater 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. 0 Smith Ms. Jaclynne Drummond January 19, 2022 Page 9 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 since the introduction of the 1,4-dioxane analysis in October 2018. The total VOC concentration in MW-6 has fluctuated since October 2018. 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 Groundwater Standard, have been below the laboratory MDL since April 2013 except for the November 2014 sampling event 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 Groundwater 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 as an estimated concentration above the NC 2L Groundwater Standards in MW-9 from October 2012 through April 2015. Benzene, 1,4-dichlorobenzene, 1,2- dichloroethane, 1,4-dioxane, and vinyl chloride have recently been detected above their respective NC 2L Groundwater Standards in MW-9. The total VOC concentration trend has been slightly increasing at MW-9 since the October 2018 sampling event. Trend analyses for total VOC concentrations in MW-36 and -36d are presented on Figures 5 and 6, respectively. Vinyl Chloride was detected above its NC 2L Groundwater Standard during the October 2020 sampling event for the first time in samples collected from MW-36 since March 2011, and was detected above the standard during the November 2021 sampling event. However, total VOC concentrations have shown a decreasing trend since the air sparging system has been operational. No VOCs have been detected above the NC 2L Groundwater 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. tD Smith Ms. Jaclynne Drummond January 19, 2022 Page 10 Additional groundwater samples were collected from MW-51R, -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. 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 Groundwater Standards, including benzene, 1,4-dichIorobenzene, 1,1-dichloroethane, methylene chloride, PCE, TCE, 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 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 -8) were installed upgradient of MW-51R, -35, and -34d, as shown on Figure 1. An initial injection of sodium lactate was completed from 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, 0 Smith Ms. Jaclynne Drummond January 19, 2022 Page 11 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. The effectiveness of the EAB injection was evaluated with quarterly sampling of MW-5R, -34, and -34d on February 4, April 8, July 30, and October 15, 2020. A report summarizing the results of the EAB injection was submitted to the SWS on June 23, 2021. Chlorinated VOC data were reviewed to evaluate concentration trends over time and to determine if dechlorination is occurring. Total VOC concentration trends for each well are presented on Figures 7 through 9. Trend results for each well are discussed below. The VOC trend analysis for MW-5R is presented on Figure 7. TCE has never been detected above the NC 2L Groundwater Standard in MW-5R and PCE has never been detected above the MDL, except during the April 2019 sampling event when PCE was detected as an estimated concentration below the standard. Vinyl chloride was the most recent analyte detected above the NC 2L Groundwater Standard (April 2019). The geochemical data indicates reducing conditions to support anaerobic dechlorination at MW-5R, shown by decreasing levels of sulfate, nitrate, DO, and negative values of ORP. Additionally, total VOC concentrations show a decreasing trend since the injection events. The trend analyses for MW-34 and -34d are presented on Figures 8 and 9, respectively. Since the injections, total VOC, PCE, TCE, and 1,1-dichloroethane concentrations have fluctuated. Concentrations of methylene chloride and cis-1,2-dichloroethene show a decreasing trend in MW-34. Total VOC concentrations in MW-34d have slightly increased, but concentrations of chlorinated VOCs are expected to decrease as the reducing conditions at the upgradient biobarrier support dechlorination. 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 II constituent, bis(2-ethylhexyl) phthalate (sampled at MW-29d only during the spring sampling event), samples collected from MW-51R, -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 spring of 2022. 0 Smith Ms. Jaclynne Drummond January 19, 2022 Page 12 If you have any questions or require further explanation, do not hesitate to call me at (919) 325-3500.

VOA 8260D The reanalysis for the following samples was analyzed outside holding time for trans-1,4-Dichloro-2- butene: WK10045-001 (MW-7), WK10045-002 (MW-23d), WK10045-003 (MW10d) and WK10045-004 (MW-9). Both runs have been reported together. The following sample was analyzed outside of analytical holding time due to the labor shortage along with an abundance of samples for trans- 1,4-Dichloro-2-butene: (Trip Blank). The sample was also reanalyzed outside of hold time due to trans-1,4 marked off for ICAL associated with run 1. WK10045-033 (MW-11) were analyzed outside of analytical holding time due to oversight and the abundance of samples in the lab. The method blank for analytical batch 22900 contained analytes: Carbon Disulfide, 1,2-Dibromo-3- chloropropane, 1,2-Dibromoethane, Dibromomethane, trans- 1,4-Dichloro-2-butene, 1,2-Dichlorobenzene, 1,4-Dichlorobenzene, cis-1,3-Dichloropropene and trans- 1,3-Dichloropropene greater than the acceptance criteria.

The data has been reported. Reanalysis of the following sample(s) was performed outside of the analytical holding time for trans-1,4- Dichloro-2-butene due to failing in the ICAL: WK10045-001 (MW-7), WK10045-002 (MW-23d), WK10045- 003 (MW-10d), and WK10045-004 (MW-9). Also, reanalysis of sample WK10045-001 (MW-7) was performed outside of the analytical holding time for Xylenes due to carryover. Reanalysis of sample WK10045-033 (MW-11) was performed outside of the analytical holding time. The Run 1 had suspected carry over of Toluene and Xylenes. Dissolved Gases RSK175 Samples WK10045-004 (MW-9) and WK10045-027 (MW-5R) required a dilution which was performed outside of the analytical holding time. Both runs have been reported. Metals 6020B The MSD for batch 22464 and parent sample WK10045-026 (MW-34), recovered marginally outside the lower limit. The associated LCS and MS passed acceptance criteria. Sulfate The method blank for analytical batch 22344 contained sulfate greater than the acceptance criteria. The associated samples, WK10045-018 (MW-10) and WK10045-020 (MW-9), did not contain detections for the target analyte; therefore, re -analysis of samples was not performed. The data has been reported. The following sample WK10045-027 (MW-5R) was diluted due to the nature of the sample matrix. The LOQ has been elevated to reflect the dilution. The method blank associated with batch 22344 had Sulfate detected at a concentration that was above the LOQ. All samples associated with this method blank that have detections for Sulfate have been flagged with a "B". Nitrate-N The following samples, WK10045-020 (MW-9) and WK10045-027 (MW-5R) was diluted due to the nature of the sample matrix. The LOQ has been elevated to reflect the dilution. Reanalysis of sample WK10045-020 (MW-9) was performed outside of the analytical holding time. This sample was reanalyzed OOH due to matrix interference upon initial analysis. Both runs have been reported. This sample WK10045-014 (MW-6) was reanalyzed OOH due to the sample's raw result being over linear range, yielding a reported result of 18mg/L. The sample was diluted at a 5x during run 2 and yielded a reported result of 18mg/L, as well. Both runs have been reported. Sulfide The MS/MSD for batch 22578 and WK10045-01 (MW-10), recovered outside the lower control limit. The associated LCS passed acceptance criteria.

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.
