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 first 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. 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 from April 20-21, 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 June 28, 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 field parameters 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 ALS Environmental, Inc. (ALS), located in Jacksonville, Florida. 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 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 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-23d Chromium MW-24 Cobalt: MW-11, -6, -8, -10, -23, -24, -30, -31, -32, -33, -34, -34d, -35, and -36 and TB-1a Thallium: MW-24, and -30 Vanadium: MW-11, -23, -24, -31d, -32, -33, -34, -34d, -35, and -36 and TB-1a Vinyl Chloride MW-8 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. Vinyl chloride was detected above the NC 2L Standard during the April 2016 sampling event in wells MW-6, -6d, -22, -23, and -23d. This analyte has not been detected in MW-6 since 2012 and has never been detected in the other wells. In order to confirm the presence of vinyl chloride, ALS reanalyzed the samples for VOCs. Vinyl chloride was not detected in the confirmatory analyses. The initial detection of vinyl chloride was attributed to laboratory error. Chloromethane was detected as an estimated concentration in the spring 2015 sampling event in the following wells: MW-6d, -10d, -22, -32, TB-1a deep, -34, -34d, -35, and -36. This analyte has never been detected in these wells with the exception of MW-6, -32, and -36. It has not been detected in MW-6 since 1994 and the detections in MW-32 and -36 were from solvent contamination in the hydrochloric acid preserved sample bottles. Sampling results for the April 2016 event did not show the presence of chloromethane in these wells. It is likely that the spring 2015 detections of chloromethane resulted from solvent contamination in the hydrochloric acid preserved sample bottles. Future sampling results will be monitored to determine if unpreserved sample bottles should be used to evaluate the influence of the hydrochloric acid preservative on the analytical results. Ms. Jaclynne Drummond June 28, 2016 Page 7 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 was not detected above the laboratory MDL in samples collected from MW-29d during the April 2015 and 2016 sampling events. The concentration trend for bis(2-ethylhexyl) phthalate in MW-29d will continue to be evaluated using the results of the spring 2017 sampling event. Copper and acetone were detected as an estimated concentrations in the equipment blank below their respective NC 2L Standard. Two trip blanks analyzed for VOCs had estimated detections of methylene chloride below the NC 2L Standard. The duplicate sample, identified as Dup, was collected from MW-6 and had similar analyte concentrations as those detected in MW-6. Table 5 presents a summary of all analytes detected during the April 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 Surface Water Quality Standards for Class C Waters 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 Ms. Jaclynne Drummond June 28, 2016 Page 8 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 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. Ms. Jaclynne Drummond June 28, 2016 Page 9 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. 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. 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. Ms. Jaclynne Drummond June 28, 2016 Page 10 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 fall of 2016.

MW-11 and -11d are background wells for the North Wake Unlined Landfill. 5. J - Indicates the analytical result is an estimated concentration between the method detection limit and the Solid Waste Section Reporting Limit. 8. 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. 9. (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. - Blank cells indicate no data collected, except for hexanoic and pentanoic acid. These acids were only reported for the 2012 monitoring events. 7. D - Analyzed at dilution. 6. B - The analyte concentration detected in the method blank was greater than the method detection limit.

NARRATIVE J1602937 Date Received: Service Request: Ground Water North Wake Unlined Landfill Wake County Solid Waste Management Sample Matrix: Project: Client: 4/22/16 All analyses were performed consistent with the quality assurance program of ALS Environmental. This report contains analytical results for samples designated for Tier II data deliverables, including results of QC samples analyzed from this delivery group. When appropriate to the procedure, method blank results have been reported with each analytical test. Analytical procedures performed by the lab are validated in accordance with NELAC standards. Parameters that are included in the NELAC Fields of Testing but are not included in the lab’s NELAC accreditation are identified in the discussion of each analytical procedure. Sample Receipt Twenty two ground water samples  were received for analysis at ALS Environmental on 4/22/2016. The samples were received in good condition and consistent with the accompanying chain of custody form. Samples are refrigerated at <6°C upon receipt at the lab except for aqueous samples designated for metals analyses, which are stored at room temperature. Volatile Organic Analyses: Method 8260B: The control criteria were exceeded for one or more surrogates in samples J1602937: Dibromofluoromethane and 1,2-Dichloroethane-d4. No further corrective action was appropriate. Method 8260B: The control criterion was exceeded for the following analytes in the Laboratory Control Sample (LCS) JQ1603393- 03 and the Laboratory Control Sample Duplicate (LCSD) JQ1603393-004 : 1,2-Dichloroethane, Bromodichloromethane, and Chloromethane. The analytes in question were not detected in the associated field samples. The sample data is not significantly affected and no further corrective action was appropriate. Method 8260B: The control criteria were exceeded for the following surrogates in the (LCS) JQ160339-04, (LCSD) JQ1603394- 04, and Method Blank JQ1603393-05: Dibromofluoromethane and 1,2-Dichloroethane-d4. The associated matrix spike recoveries of target compounds were in control, indicating the analysis was in control. The surrogate outlier is flagged accordingly. No further corrective action was appropriate. Method 8260B: The control criterion was exceeded for the following analytes in Laboratory Control Sample (LCS) JQ1603374-03 and the Laboratory Control Sample Duplicate (LCSD) JQ1603374-04: l,2-Dichloroethane, Bromodichloromethane, and Chloromethane. The analytes in question were not detected in the associated field samples. The sample data is not significantly affected. No further corrective action was appropriate. Method 8260B: The control criteria were exceeded for the following surrogates in LCS JQ1603374-03, LCSD JQ1603374-04, and Method Blank JQ1603374-05: 1,2-Dichloroethane-d4 and Dibromofluoromethane. The surrogate outlier is flagged accordingly. No further corrective action was appropriate. Semi-Volatile Organic Analyses: Method 8011: The upper control criterion was exceeded for the following surrogate(s) in samples J1602937-018: 1,1,1,2- Tetrachloroethane. No target analytes were detected in the sample. The error associated with an elevated recovery equates to a high bias. The quality of the sample data is not significantly affected. No further corrective action was appropriate.

For your reference, these analyses have been assigned our service request number J1602937. All analyses were performed according to our laboratory’s NELAP and DoD-ELAP-approved quality assurance program. The test results meet requirements of the current NELAP and DoD-ELAP standards, where applicable, and except as noted in the laboratory case narrative provided. For a specific list of NELAP and DoD-ELAP-accredited analytes, refer to the certifications section at www.alsglobal.com. Results are intended to be considered in their entirety and apply only to the samples analyzed and reported herein. If you have any questions, please call me at (805) 526-7161. Respectfully submitted, ALS | Environmental Kate Aguilera Project Manager Page 153 of 165 2655 Park Center Dr., Suite A Simi Valley, CA 93065 T: +1 805 526 7161 F: +1 805 526 7270 www.alsglobal.com RIGHT SOLUTIONS | RIGHT PARTNER Client: Wake County Solid Waste Management Service Request No: J1602937 Project: North Wake Unlined Landfill _______________________________________________________________________________ CASE NARRATIVE The samples were received intact under chain of custody at the Simi Valley facility on April 26, 2016 and were stored in accordance with the analytical method requirements. Please refer to the sample acceptance check form for additional information. The results reported herein are applicable only to the condition of the samples at the time of sample receipt. Carbon Dioxide Analysis The samples were analyzed for carbon dioxide using a gas chromatograph equipped with a thermal conductivity detector (TCD). A known amount of liquid was displaced by injecting 8.0 milliliters of helium creating a headspace in the sample vial. Each sample vial was agitated using a sonic disrupter for fifteen minutes and then allowed to equilibrate for at least four hours. A volume of the headspace was withdrawn using a gas-tight syringe and analyzed using a manual injection technique. The amount of dissolved gases (carbon dioxide) in the original sample was calculated using Henry’s Law. This method was performed with guidance from RSK 175 as described in laboratory SOP VOA-DISGAS. This analyte is included on the laboratory’s NELAP and DoD-ELAP scope of accreditation, however it is not part of the AIHA-LAP accreditation. Methane, Ethene and Ethane Analysis The samples were also analyzed for methane, ethene, and ethane using a gas chromatograph equipped with a flame ionization detector (FID). A known amount of liquid was displaced by injecting 8.0 milliliters of helium creating a headspace in the sample vial. Each sample vial was agitated using a sonic disrupter for fifteen minutes and then allowed to equilibrate for at least two hours. A volume of the headspace was withdrawn using a gas-tight syringe and analyzed using a manual injection technique. The amount of dissolved gases (methane, ethene and ethane) in the original sample was calculated using Henry’s Law. This method was performed with guidance from RSK 175. This method is included on the laboratory’s NELAP and DoD-ELAP scope of accreditation, however it is not part of the AIHA-LAP accreditation. Any analytes flagged with an X are not included on the laboratory’s NELAP or DoD-ELAP accreditation. ______________________________________________________________________________________ The results of analyses are given in the attached laboratory report.

This report contains analytical results for samples designated for Tier II data deliverables, including results of QC samples analyzed from this delivery group. When appropriate to the procedure, method blank results have been reported with each analytical test. Analytical procedures performed by the lab are validated in accordance with NELAC standards. Parameters that are included in the NELAC Fields of Testing but are not included in the lab’s NELAC accreditation are identified in the discussion of each analytical procedure. Sample Receipt Sixteen ground water samples  were received for analysis at ALS Environmental on 4/21/2016. The samples were received in good condition and consistent with the accompanying chain of custody form. Samples are refrigerated at <6°C upon receipt at the lab except for aqueous samples designated for metals analyses, which are stored at room temperature. Volatile Organic Analyses: Method 8260B: The control criterion was exceeded for the following surrogate in several samples: 4-Bromofluorobenzene. The error associated with an elevated recovery equates to a high bias. The quality of the sample data is not significantly affected. No further corrective action was appropriate. Method 8260B: The control criterion was exceeded for several analytes in Laboratory Control Sample (LCS) and Duplicate Laboratory Control Sample (DLCS). The sample data is not significantly affected. No further corrective action was appropriate. Semi-Volatile Organic Analyses: No significant data anomalies were noted with this analysis. Metals Analyses: No significant data anomalies were noted with this analysis. General Chemistry Analyses: Method SM4500-S2 F (Sulfide): The Stock Standard and Titrant for this analysis were expired in March/April 2016. After confirming all quality control samples, analysis was performed. There is no reason to believe there is an effect on the sample data values. Method: SM4500-S2 F Had NCAR JC0465 generated. Subcontracted Analytical Parameters: An aliquot of the samples were delivered to ALS in Rochester, NY for Organic Acid determination. The certified analytical report has been included in its entirety in this report. An aliquot of the samples were delivered to ALS in Simi Valley, CA for RSK-175 determination.

For your reference, these analyses have been assigned our service request number J1602895. All analyses were performed according to our laboratory’s NELAP and DoD-ELAP-approved quality assurance program. The test results meet requirements of the current NELAP and DoD-ELAP standards, where applicable, and except as noted in the laboratory case narrative provided. For a specific list of NELAP and DoD-ELAP-accredited analytes, refer to the certifications section at www.alsglobal.com. Results are intended to be considered in their entirety and apply only to the samples analyzed and reported herein. If you have any questions, please call me at (805) 526-7161. Respectfully submitted, ALS | Environmental Kate Aguilera Project Manager Revision Page 113 of 126 Client: CDM Smith, Inc. Service Request No: J1602895 Project: North Wake Unlined Landfill _______________________________________________________________________________ CASE NARRATIVE The samples were received intact under chain of custody at the Simi Valley facility on April 22, 2016 and were stored in accordance with the analytical method requirements. Please refer to the sample acceptance check form for additional information. The results reported herein are applicable only to the condition of the sample(s) at the time of sample receipt. Carbon Dioxide Analysis The samples were analyzed for carbon dioxide using a gas chromatograph equipped with a thermal conductivity detector (TCD). A known amount of liquid was displaced by injecting 8.0 milliliters of helium creating a headspace in the sample vial. Each sample vial was agitated using a sonic disrupter for fifteen minutes and then allowed to equilibrate for at least four hours. A volume of the headspace was withdrawn using a gas-tight syringe and analyzed using a manual injection technique. The amount of dissolved gases (carbon dioxide) in the original sample was calculated using Henry’s Law. This method was performed with guidance from RSK 175 as described in laboratory SOP VOA-DISGAS. This analyte is included on the laboratory’s NELAP and DoD-ELAP scope of accreditation, however it is not part of the AIHA-LAP accreditation. Methane, Ethene and Ethane Analysis The samples were analyzed for methane, ethene, and ethane using a gas chromatograph equipped with a flame ionization detector (FID). A known amount of liquid was displaced by injecting 8.0 milliliters of helium creating a headspace in the sample vial. Each sample vial was agitated using a sonic disrupter for fifteen minutes and then allowed to equilibrate for at least two hours. A volume of the headspace was withdrawn using a gas-tight syringe and analyzed using a manual injection technique. The amount of dissolved gases (methane, ethene and ethane) in the original sample was calculated using Henry’s Law. This method was performed with guidance from RSK 175. This method is included on the laboratory’s NELAP and DoD-ELAP scope of accreditation, however it is not part of the AIHA-LAP accreditation. Any analytes flagged with an X are not included on the laboratory’s NELAP or DoD-ELAP accreditation. ______________________________________________________________________________________ The results of analyses are given in the attached laboratory report.
