The county operates a Construction and Demolition (C&D) landfill and maintains two closed unlined landfills identified as Unit 1 and Unit 2&3 (Figure 2). In December 1997, Cabarrus County discontinued disposal of municipal solid waste in Unit 2&3 of the landfill. A low permeability cap was installed to close the landfill in August 1998. C&D debris was disposed of on top of the closed Unit 3 landfill until June 2008. Permanent closure of the Unit 3 landfill area with a low -permeability cap and gas vents was completed in June 2010. 1.1.1 Corrective Action In December 2008, CDM Smith, on behalf of the County, submitted an Assessment of Corrective Measures Report to the SWS for the closed landfill Unit 2&3 in accordance with North Carolina Solid Waste Management Rule 15 NCAC 1313.1635. Monitored natural attenuation and institutional controls paired with in situ remediation by enhanced bioremediation was selected as the remedy to address groundwater contamination by select VOCs at the facility. In situ remediation efforts were to be focused on the bedrock contamination near monitoring wells MW- E Rep and -E Deep. Groundwater contamination in the area of MW-E Deep is caused by migration of leachate from the closed landfill Unit 2&3 downward into the shallow fractured bedrock, thereby allowing low-level VOCs to migrate into this area prior to being attenuated below 15A NCAC 02L .0202 (NC 2L) Groundwater Standards. Following approval of the CAP in September 2009 and the Phase I injection permit, six injection wells were installed upgradient of the MW-E cluster in October 2009 as shown on Figure 3. A 3% solution of potable water and EOS® 450, which is an emulsion of soybean oil and water, was injected simultaneously into the injection wells from November 2-6, 2009. A total of 38,100 gallons of the solution were injected with each well receiving approximately 6,350 gallons. After the Phase I injection, a November 2013 sampling event showed that groundwater contaminant concentrations had increased and levels exceeding the applicable NC 2L Groundwater Standards had been detected in monitoring wells near the property line. Thus, the groundwater conditions were re-evaluated in accordance with the CAP and a Phase II injection was implemented. Following approval of the injection permit in January 2014, the Phase II injection was completed from February 10-18, 2014, using potable water and a 10% solution of 60% SRS®-FR large droplet emulsified vegetable oil substrate. SRS®-FR is specifically designed for use in fractured bedrock environments and is a mixture of 60% emulsified vegetable oil, 20% water, 5-15% of proprietary emulsifiers and nutrients, and 5% sodium lactate. The nutrient component of SRS®- FR further enhances the microbial population growth. A total of 9,966 gallons of the solution were injected during the Phase II event with each well receiving approximately 1,661 gallons. CDM Smith 1-1 Section 1 1.2 Geologic Setting The site is located in the Charlotte belt of the Piedmont Physiographic Province. The Piedmont Physiographic Province in North Carolina is characterized by gentle to steep, hilly terrain with small quantities of alluvium. Saprolite, a clay -rich residual material that is the product of in -place chemical weathering and leaching of bedrock, is commonly found in the Piedmont Province. Beneath the saprolite is a transition zone of weathered bedrock. The thickness of regolith above unweathered bedrock averages about 50 feet. The transition zone below the saprolite is generally the zone in which most of the lateral groundwater flow takes place. The porosity within the transition zone decreases with depth, as the degree of weathering decreases. 1.3 Aquifer Setting and Characteristics Groundwater monitoring wells have been installed surrounding landfill Unit 1 and Unit 2&3. These wells are generally completed to depths corresponding with the top of rock and are considered representative of the saprolite/transition zone. Monitoring wells AMW-1d, AMW-2d, MW-3 Deep, MW-E Deep, MW-H Deep, and MW-L Deep are installed in fractured bedrock in order to monitor deeper water quality and obtain vertical gradient information; monitoring well MW-E Rep is installed in regolith above unweathered bedrock. Treatment of groundwater contamination by select VOCs is focused on the bedrock contamination near MW-E Rep and MW- E Deep. Well construction records for injection and assessment wells are included in Appendix A. Monitoring well construction details are provided in Table 1. Groundwater in the weathered bedrock is generally restricted to fractures and other discontinuities. The fractures are generally most numerous and have the largest openings near the top of the unweathered bedrock. The amount and location of groundwater in the unweathered bedrock varies greatly dependent on the depth, openness, and degree of connection between fractures. Groundwater elevations from the Fall 2023 semi-annual sampling event were used to construct potentiometric contours. Well locations and potentiometric contours are presented on Figure 2. The groundwater elevation contours indicate a southerly groundwater flow direction consistent with the site topography. Historical groundwater elevations are provided in Table 2. Groundwater flow direction and discharge is largely confined by the stream east of Unit 2&3, and to a lesser extent, the small drainage feature to the south. In situ horizontal hydraulic conductivity (slug) tests performed on monitoring wells at the site. Site horizontal hydraulic conductivities, gradients, and flow velocities are provided in Table 3. 1.4 Contaminant Distribution 1.4.1 Groundwater Quality Groundwater quality parameters recorded in the field are provided in Table 4. Groundwater quality analytical results for detected metals and Appendix I volatile organic compounds (VOCs) are provided in Table 5a and Table 5b, respectively. There is no clear trend depicting whether occurrences of detected metals and VOCs above respective NC 2L Standards have been increasing or decreasing since beginning sampling activities. 1-2 Smith Section 1 Monitoring well MW-3 was installed in 1992 and MW-X was installed in 1993. Monitoring wells MW-A, MW-B, MW-C, MW-D, MW-F, MW-G were installed in 1994. Monitoring well MW-E Rep was installed in 1996 and MW-E Deep, MW-H, MW-H Deep, MW-I, MW-J, MW-K, and MW-L were installed in 1999. Monitoring wells MW-1 and MW-9 were installed during an unspecified year in the 1990s. Monitoring wells MW-3 Deep, MW-L Deep and MW-M were installed in 2003 while CD- 1d was installed the following year; CD-1s was installed one year later, in 2006. Monitoring wells AMW-1s, AMW-1d, AMW-2s, AMW-2d, and CD-4 Rep were installed last in 2009. Monitoring wells have been sampled on a semi-annual basis since their respective installation years. In addition to VOC and metal analyses, samples from the site background monitoring well CD-1s and monitoring wells AMW-1s, AMW-1d, AMW-2s, AMW-2d, MW-A, MW-E Rep, MW-E Deep, and MW-L are analyzed for the following parameters in order to evaluate the effectiveness of the natural attenuation and the Phase II injection event: alkalinity, dissolved oxygen, biological oxygen demand (BOD), chemical oxygen demand (COD), chloride, nitrate, sulfate, sulfide, total organic carbon (TOC), ferrous iron, dissolved gases (methane, ethane, ethene, and carbon dioxide), volatile fatty acids (acetic, butyric, lactic, propionic, and pyruvic), and dissolved hydrogen. A summary of the MNA parameter analytical results since 2012 is provided in Table Sd. VOCs in most of the monitoring wells have been below the NC 2L groundwater standards. Samples from AMW-1d and -2d and MW-1, -A, -B, -E Rep, -E Deep, -F, -G, and -H had VOC detections above the NC 2L standards during the September 2023 sampling event, with several different groundwater constituents exceeding the NC 2L standard for a majority of these wells. These constituents include: benzene, 1,4-dioxane, 1,4-dichlorobenzene, 1,1-dichloroethane, 1,2- dichloroethane, 1,2-dichloropropane, cis- 1,2-dichloroethene, 1,2-dichloropropane, tetrachloroethene, trichloroethene, and vinyl chloride. Metals detected above the standards are likely naturally occurring based on concentrations in the background monitoring wells or are from elevated turbidity at the time of sample collection; detections above the NC 2L standards during the September 2023 sampling event are provided in Table 6. Field logs are provided in Appendix B. Analytical reports are provided in Appendix C. 1.4.2 Surface Water Quality Surface water sampling data, specifically metal and VOC analysis, from sample locations SW-1 and SW-2 has been recorded since 2012 and are provided in Table Sc. Surface water sampling locations are shown on Figure 2. These locations are monitored as part of the semi-annual sampling. Several estimated concentrations of VOCs have been reported in samples from each location throughout the years, but generally 1,4-Dioxane appears to be the most frequent. Several metals have been detected at low levels in the surface water samples and are most likely attributed to naturally occurring conditions. Metals detected at levels that have historically exceeded the NC 2B or In -Stream Target Value Freshwater Aquatic Life or Fish Consumption Standard include: Chromium, Cobalt, Copper, Lead, Nickel, Selenium, Silver, and Zinc. Note that metals and VOCs were not analyzed during the September 2023 sampling event for SW-1 and SW- 2 and only results from various months between May 2012 and April 2023 are shown. CDM Smith 1-3 Section 1 1.5 Site Conceptual Model Available data and historical investigations at the site confirm that the two closed unlined landfills identified as Unit 1 and Unit 2&3 are the source of VOCs observed in groundwater. Groundwater flows in a southerly direction consistent with the site topography. The surficial aquifer discharges to the small stream to the east of Unit 2&3. Historic surface water sampling indicates that VOC contamination (1,4-dioxane) is present but does not exceed North Carolina In - Stream Target Value Freshwater Aquatic Life Standard. Historic surface water sampling indicates that metals contamination has been present but are likely naturally occurring. Since November 2 02 1, surface water sampling locations have dry or metals concentrations have been below laboratory reporting limits, except for occasional detections of barium which has not exceeded the standard. 1.6 Regulatory Status In December 1997, Cabarrus County discontinued disposal of municipal solid waste in Unit 2&3. In August 1998, Unit 2&3 was closed. Currently, the County operates a stand-alone C&D Landfill at the site. CDM 1-4 Smith Section 2 Corrective Action Summary 2.1 Physical Changes in Aquifer Conditions The injections of EOS® 450 and 60% SRS®-FR into the aquifer did not produce any physical changes in aquifer conditions. 2.2 Chemical Changes in Aquifer Conditions Dissolved oxygen has shown a decreasing trend following the EOS® 450 and 60% SRS®-FR injections. Groundwater conditions are generally reverting to background conditions within 50 feet of the injection zone as shown in the data provided in Table 4 and Table 5d. 2.3 Physical Changes in Plume Characteristics As contaminant degradation occurred the plume progressively reduced in size over time. 2.4 Chemical Changes in the Plume The initial Phase I injection of an emulsion of soybean oil and water in October 2009 successfully degraded PCE and TCE to daughter products in the injection area and neither compound has been detected above the NC 2L Groundwater Standards in MW-E Deep since the Phase I injection in November 2009. It was assumed that the EOS® 450 would be viable for a period of 3 to 5 years. However, samples collected from the MW-E cluster and wells downgradient of the injection area during the November 2013 sampling event showed that groundwater contaminant concentrations had increased and levels exceeding the applicable NC 2L Groundwater Standards had been detected in monitoring wells near the property line. Due to the increasing downgradient contaminant concentrations and NC 2L Groundwater Standard exceedances near the property line, groundwater conditions were re-evaluated in accordance with the CAP and the Phase II injection of emulsified vegetable oil was implemented in January 2014. To assess the biological conditions in the injection area prior to initiating the Phase II injection, groundwater samples were collected from MW-E Rep, -E Deep, AMW-1s, -1d, -2s, and -2d in January 2014 and analyzed for Dehalococcoides spp (DHC), the bacteria responsible for degrading the chlorinated ethene species of VOCs. The specific genes of the bacteria that promote dechlorination were also analyzed. Analytical results for the DHC analyses are provided in Table 7 and show that a sufficient population exists at monitoring wells MW-E, -E Deep, and assessment monitoring well AMW-2s for reductive dechlorination by enhanced anaerobic bioremediation. DHC was detected at low concentrations in assessment monitoring wells AMW-1d and -2d and was not detected at AMW-1s. The absence of DHC at AMW-1s is likely associated with relatively low VOC concentrations. To monitor the progress of the Phase II injection and the geochemical and biological response of the aquifer after its implementation, groundwater samples were collected quarterly from monitoring wells MW-E Rep and -E Deep and assessment wells AMW-1s, -1d, -2s, and -2d. The first and third quarterly sampling events were completed in conjunction with the May and November 2014 semi-annual sampling events, respectively. The second quarterly sampling event CDM Smith 2-1 Section 2 was completed in August 2014 and the fourth quarterly sampling event was completed in March 2015. A 15-month post -injection sampling event was completed in May 2015. Water quality measurements of pH, temperature, ORP, DO, conductivity, turbidity, and ferrous iron were collected during each sampling event. In addition, the quarterly samples were submitted to an analytical laboratory for analysis of nitrate, sulfate, alkalinity, chloride, COD, VOCs, dissolved gasses, and metabolic acids. North Carolina Appendix I metals were collected during events that corresponded with the semi-annual sampling program. Additional samples were collected during the fourth quarterly sampling event (March 2015) from monitoring wells MW-E Rep and -E Deep and assessment wells AMW-1s, -1d, -2s, and -2d and analyzed for DHC to assess the biological conditions in the injection area after initiating the Phase II injection. A sufficient population of DHC existed at assessment monitoring well AMW-1d for reductive dechlorination by enhanced anaerobic bioremediation and DHC was detected at low concentrations in monitoring well MW-E Deep. Detections of DHC in AMW-1d indicated a healthy population of DHC in the primary bedrock treatment zone surrounding the injection wells. DHC detections in MW-E Deep was an indication that active treatment in bedrock was also occurring downgradient. DHC was not detected at MW-E Rep, AMW-1s, -2s, or -2d and was likely due to reduced VOC concentrations from upgradient treatment. Analytical results for the DHC analyses are provided in Table 7. On September 28, 2015, a report summarizing the results of the Phase II injection was submitted to the SWS. The report stated that the Phase II injection of emulsified vegetable oil replenished the carbon source and complete reductive dechlorination is occurring at MW-E, -E Deep, and AMW-1d. The presence of DHC populations and functional genes in MW-E Deep and AMW-1d demonstrate that the treatment process can achieve complete chlorinated VOC degradation if a sufficient carbon donor is present. As part of the semi-annual monitoring program, additional groundwater samples were collected from the background well CD-1s; monitoring wells MW-A, -E Rep, -E Deep, -L, and -3; and assessment wells AMW-1s, -1d, -2s, and -2d. Samples were analyzed for monitored natural attenuation parameters. These additional samples were collected to evaluate natural attenuation and the effectiveness of the Phase II injection as part of the CAP. Geochemical results are provided in Table 5d. Contaminant concentration trends for MW-A, -3, -E Rep, -E Deep, AMW-1s, -1d, -2s, and -2d were evaluated to determine the effectiveness of natural attenuation and the Phase II injection. Figures 4 through 11 present total VOC contaminant concentration data for each well. An isoconcentration contour map with data from the September 2023 sampling event is provided on Figure 12. The total VOC trend analysis from September 1994 through September 2023 for MW-A is presented on Figure 4. Total VOC concentrations increased in MW-A between June 1995 and March 2003 and show a decreasing trend from March 2003 to September 2023. The total VOC trend analysis from July 1998 through October 2022 for MW-3 is presented on Figure 5. Note that MW-3 is only sampled during the Spring sampling events and VOCs were not analyzed from the September 2023 event. Total VOC concentrations show an increasing trend. 1,1-Dichloroethane, PCE, and TCE are the only analytes that have been detected in MW-3 above the NC 2L Groundwater Standards. The geochemical data indicates aerobic conditions at MW-3. VOC concentrations in MW-3 Deep have not been detected above the standards. 2-2 Smith Section 2 The total VOC trend analyses for MW-E Rep and -E Deep are presented on Figures 6 and 7, respectively. Total VOC concentrations in MW-E Rep and -E Deep have decreased since the November 2009 Phase I injection. PCE and TCE have not been detected above the NC 2L Groundwater Standards in MW-E Deep since the Phase I injection and have not been detected above the MDL since August 2010. Delivery of the carbon substrate (i.e., SRS®-FR) during the Phase II injection was effective based on the increase in COD at MW-E Deep. Historical geochemical data shows reducing conditions exist at the MW-E cluster based on low DO and high methane concentrations. ORP has fluctuated since the November 2016 sampling event. The increase in metabolic acids and ferrous iron at MW-E Deep also indicates that a reducing subsurface environment exists. A geochemically reducing environment is favorable for anaerobic reductive dechlorination. The total VOC trend analyses for AMW-1s Rep and -1d are presented on Figures 8 and 9, respectively. Total VOC concentrations in AMW-1s show an increasing trend from November 2010 to May 2013 but show a decreasing trend from May 2013 to September 2023. VOCs have not been detected above the standards in AMW-1s since the May 2019 sampling event. Total VOC concentrations in AMW-1d show a decreasing trend from the initial sampling in October 2009 to November 2019 but have fluctuated since the November 2019 sampling event. Historical data shows reducing conditions existed at AMW-1d but DO and ORP have fluctuated since the November 2017 sampling event. The concentration of vinyl chloride generally increased from the Phase II injection to November 2017 while TCE concentrations decreased, indicating anaerobic reductive dechlorination is occurring as vinyl chloride is a daughter product of TCE. However, from November 2017 to September 2020, TCE concentrations increased, and the concentration of vinyl chloride decreased. TCE has not been detected above the standard since September 2020 and results show that the concentration of vinyl chloride increased. The total VOC trend analyses for AMW-2s and -2d are presented on Figures 10 and 11, respectively. Total VOC concentrations at AMW-2s show an increasing trend between the initial sampling event in October 2009 and November 2014 and have fluctuated since the November 2014 sampling event, but generally show a decreasing trend. Total VOC concentrations show an increasing trend at AMW-2d from November 2010 to November 2017 but have fluctuated since then. The AMW-2 cluster is located farthest downgradient of the injection area and the shallow well is screened in partially weathered rock. Geochemical results indicate an aerobic subsurface environment. 2.5 Refining the Site Conceptual Model The conceptual model will be refined as necessary based on the semi-annual sampling results. 2.6 Compliance Boundary Status The two-phase injection approach has generally reset the MNA clock and has reduced contaminants at the compliance boundary below NC 2L Groundwater Standards for a majority of the wells. However, groundwater constituents including benzene, 1,4-dioxane, 1,4- dichlorobenzene, 1,1-dichloroethane, 1,2-dichloroethane, 1,2-dichloropropane, cis-1,2- dichloroethene, 1,2-dichloropropane, tetrachloroethene, trichloroethene, and vinyl chloride have shown decreases in concentration but still exceed the NC 2L Groundwater Standard in AMW-1d and -2d and MW-1, -A, -13, -E Rep, -E Deep, -F, -G, and -H. Smith 2-3 Section 2 2.7 Off -site Migration of Contaminants of Concern There are no off -site exceedances of contaminants of concern based on the surface water analytical results provided in Table Sc. CDM 2-4 Smith Section 3 Conclusion The Phase 1 injection of emulsified soybean oil and water successfully caused degradation of TCE and PCE to daughter products in the injection area. The Phase 2 injection of emulsified vegetable oil supplied a long-lasting carbon source and complete reductive dichlorination is still occurring in each well. Since the Site is an unlined landfill and due to the nature of the geology in the area, it is not surprising that several monitoring wells continue to have contaminants above NC 2L Groundwater Standards. However, the two-phase injection approach is successfully resetting the MNA clock and has reduced contaminants at the compliance boundary below NC 2L Groundwater Standards, with the exception of benzene, 1,4-dioxane, 1,4-dichlorobenzene, 1,1-dichloroethane, 1,2-dichloroethane, 1,2-dichloropropane, cis-1,2-dichloroethene, 1,2-dichloropropane, tetrachloroethene, trichloroethene, and vinyl chloride. The VOCs have shown decreases in concentration but still exceed the NC 2L Groundwater Standard in AMW-1d and -2d and MW-1, - A, -B, -E Rep, -E Deep, -F, -G, and -H. An additional injection will likely be necessary in the future once all electron donors have been consumed and complete dechlorination stalls. Semi-annual monitoring data will be used to determine when another injection is needed. Smith 3-1 Section 4 References CDM Smith 2024. September 2023 Semi -Annual Sampling Report.

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. 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 D3 Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference. H3 Sample was received or analysis requested beyond the recognized method holding time. L2 Analyte recovery in the laboratory control sample (LCS) was below QC limits. Results for this analyte in associated samples may be biased low. MO Matrix spike recovery and/or matrix spike duplicate recovery was outside laboratory control limits. M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery. N2 The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A complete list of accreditations/certifications is available upon request.
