This letter report presents the results of the semi-annual sampling event that was recently completed at the North Wake Closed Unlined Landfill and constitutes the second semi-annual sampling event for 2016. 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, TB-1a deep and surface water sampling locations: SW-2, -3, -7, and -8. Monitoring wells MW-28, -28d, -33, -34, -34d, and -35 are sampled annually during the spring event. 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 North Wake Closed Unlined Landfill were collected on September 1 and 12-14, 2016. 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. Ms. Jaclynne Drummond December 16, 2016 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 was 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 samples were analyzed 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, and -36 were analyzed for natural attenuation parameters per the Corrective Action Plan (CAP) that was approved by the North Carolina Department of Environmental Quality - Solid Waste Section (SWS) in March 2010. The groundwater and surface water samples were analyzed by Shealy Environmental Services, Inc. located in West Columbia, South Carolina. In accordance with SWS guidelines the analytical results were reported to the laboratory specific method detection limit (MDL) and are quantifiable at or below SWS Limits (SWSLs). All monitoring wells and surface water locations for the closed Unlined Landfill had detections of analytes above the MDL with a majority of the detections below SWSLs. These detections were qualified as estimated or “J” flags. “B” flags, which indicate an analyte was detected in the method blank, were also reported. The following list summarizes which analytes were detected above the SWSL at each sample location. Underlined analytes exceeded the 15A NCAC 02L .0202 (NC 2L) Groundwater Quality Standard, Groundwater Protection Standard, or the 15A NCAC 02B (NC 2B) 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 September 2016 sampling events is presented in Table 4. Laboratory data reports are provided in Appendix A.

The “J” flag constituents above the standards along with their locations are listed below. Antimony: MW-6d, and -23d Cobalt: MW-11, -8, -10, -23, -30, -32, and -36 Copper: SW-3 Lead: SW-3 Thallium: MW-6d, -22, and -23 Vanadium: MW-11, -11d, -5R, -6, -6d, -7, -8, -8d, -9, -10, -10d, -22, -23, -23d, -24, -29d, -30, -31, -31d, -32, -36, and TB-1a deep Vinyl Chloride: MW-7 It is likely that the recent and historic detections of chloroform in wells MW-24, -31, -31d, TB-1a, and TB-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 landfill. 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. 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. Arsenic, barium, copper, and acetone were detected as estimated concentrations in the equipment blank below their respective NC 2L Standard. Vanadium was detected above the NC 2L Standard in the equipment blank. Two trip blanks analyzed for VOCs had no detections above the MDL. 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 Ms. Jaclynne Drummond December 16, 2016 Page 7 during the September 2016 sampling event that exceeded the NC 2L or Groundwater Protection Standards. Corrective Action Effectiveness Evaluation The SWS expressed concern in May 2008 that VOCs may be migrating beyond the landfill 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 landfill 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. Surface water sample locations SW-7 and SW-8, located on Abbott’s Creek, were added to the semi- annual monitoring program in November 2008. Samples collected from SW-7 and SW-8 since being added to the monitoring program have never had VOCs detected above the NC 2B Surface Water Quality Standards or SWSLs. 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 landfill 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 Ms. Jaclynne Drummond December 16, 2016 Page 8 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 has shown a decreasing trend since the May 2008 sampling event. Vinyl chloride has not been detected above the laboratory MDL since the April 2013 sampling event. Benzene, which historically has exceeded the NC 2L Standard, has been detected below the laboratory MDL since April 2013 with the exception of the November 2014 sampling event (1.1 ppb) when it was detected slightly above the NC 2L Standard (1 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 reported as “J” flag detections below the NC 2L Standards since the March 2011 sampling event. 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 landfill monitoring wells. VOCs were not detected above the NC 2L Standards in MW-9 from August 2012 through April 2015. There was a “J” flag detection above the NC 2L Standard of 1,2-dichloroethane (0.42 ppb) during the October 2015 sampling event and a detection of vinyl chloride (1.0 ppb) above the NC 2L Standard during the April 2016 sampling event. No VOCs were detected above the NC 2L Standards during the September 2016 sampling event. Total VOC concentrations in MW-9 show a decreasing trend. 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. Ms. Jaclynne Drummond December 16, 2016 Page 9 Additional groundwater samples were collected from MW-5R, -6, -8, -9, -10, -11, and -36 for evaluation of monitored natural attenuation as part of the corrective action program as required by SWS guidelines. These parameters include biochemical oxygen demand, chemical oxygen demand, alkalinity, nitrate, chloride, sulfate, sulfide, total organic carbon, carbon dioxide, methane, ethane, ethene, ferrous iron, volatile fatty acids, dissolved hydrogen, and field measurements of pH, temperature, conductivity, ORP and DO. 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. 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-5R, -6, -8, -9, -10, -11, and -36 will continue to be analyzed for natural attenuation parameters during the semi-annual events. 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 2017.

Case Narrative CDM Smith Lot Number: RI14018 SC DHEC No: 32010 NC Field Parameters No: 5639 NELAC No: E87653 NC DENR No: 329 Project Name: North Wake Unlined Landfill Project Number: This Report of Analysis contains the analytical result(s) for the sample(s) listed on the Sample Summary following this Case Narrative. 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 Shealy Environmental Services, Inc. ("Shealy") Quality Assurance Management Plan (QAMP), standard operating procedures (SOPs), and Shealy policies. Any exceptions to the NELAC standards, the QAMP, SOPs or policies are qualified on the results page or discussed below. If you have any questions regarding this report please contact the Shealy Project Manager listed on the cover page. BOD SM5210B Sample RI14018-010 (MW-36) had all six flags. A six flag means the DO depletion is less than 2.00 mg/L. A COD were done before the BOD dilutions were chosen. The results for the COD were 175.55 mg/L (this is the result of the COD cut in half). This sample will need larger dilutions next time it is analyzed. Metals 6020A The LCS associated with MW-29D, MW-7, MW-23d, MW-31d, TB-1a deep, DUP and SW-8 was bias high for beryllium, but these samples were non- detect for beryllium.

VOA 8260B Samples RI15007-002,003,004,008,012 were all re-run for trans-1,4-Dichloro-2-butene out of a headspace vial. Sample RI15007-010 was initially run at a 1X dilution and was rerun accidently for trans- 1,4-Dichloro-2-butene at a 10X. Samples RI14019-017,018 were initially run at a 50x based on screening and both were accidently re-run at 50x. Lower dilution was needed at 5x which was run 3. Analysis/run 3 is being reported and was run outside of the 7 day holding time for the unpreserved vials. The MS associated with these samples had low internal standard recovery causing all the compounds to recover bias high. The MS/MSD were re- analyzed outside of the 7 day holding time and are being reported. The associated CCV and LCS passed all criteria in the analytical run where the MSD failed recovery due to low internal standard.
