This letter report presents the results of the semi-annual sampling event that was recently completed at the Closed Feltonsville Landfill, and constitutes the first semi-annual sampling event for 2016. The current groundwater monitoring network consists of the following wells: MW-2, -4, -6, -8, -9, -10, -11, -12, -13, -14, -15, -16, -17, -18, -19, -20, -21, -22, -23, -24, -25, -26, -27, -28, and -29 as well as surface water sampling locations SW-1, -2, and -3. Monitoring wells MW-2, -6, -8, -9, -10, -11, -12, -13, -14, -15, -16, -17, -18, -19, -20, -28, and -29 monitor the closed Feltonsville landfill. The remaining wells (MW-4, -21, -22, -23, -24, -25, -26, and -27) monitor the old cells in the back of the landfill property. 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 Closed Feltonsville Landfill were collected on April 25-27, 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 27, 2016 Page 2 After depth to groundwater was determined, 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 in the field for pH, conductivity, temperature, turbidity, dissolved oxygen, and oxidation-reduction potential 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 parameters at the time of sampling are provided in Table 3. Sampling Results Groundwater and surface water samples were analyzed by ALS Environmental, Inc., located in Jacksonville, Florida, for the North Carolina Appendix I volatile organic compounds (VOCs) plus dichlorodifluoromethane and Appendix I metals plus mercury. Additional samples were collected from select monitoring wells to evaluate natural attenuation and to evaluate the effectiveness of the corrective action. Results of the additional sampling and an evaluation of natural attenuation are discussed in the next section of this report. In accordance with North Carolina Department of Environmental Quality - Solid Waste Section (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 Feltonsville 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 indicates the analytes detected above the MDL at each sampling location. No “J” flag detections are provided. 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. A complete summary of all detected and estimated concentrations for the March 2011 through the April 2016 sampling events, as well as historical detections of herbicides, pesticides, and polychlorinated biphenyls, is provided in Table 4. Laboratory data reports are provided in Appendix A.

The equipment blank had “J” flag detections of copper and acetone below the NC 2L Standard. No VOCs were detected in the trip blank above the detection limit. Table 5 presents a summary of all parameters detected during the April 2016 sampling event that exceeded the NC 2L or Groundwater Protection Standards. Monitored Natural Attenuation Sampling Additional groundwater samples were collected from the background well, MW-2, and downgradient monitoring wells MW-8, -9, -10, -12, -13, and -14. The samples were analyzed for alkalinity, biochemical oxygen demand, chemical oxygen demand, carbon dioxide, chloride, dissolved hydrogen, methane, ethane, ethene, volatile fatty acids (i.e. acetic, butyric, lactic, propionic, and pyruvic), nitrate, sulfate, sulfide, and total organic carbon. Ferrous iron was also analyzed using a HACH test field kit due to the short hold time (i.e. 15 minutes). These additional samples were collected to monitor for natural attenuation as part of the approved corrective action program as required by SWS guidelines. Additional samples were also collected from wells MW-19 and -29, which are located down-gradient of the injection area, in order to monitor the effectiveness of the injection. Sampling results are provided in Table 6 and trend figures of total detected VOCs for select wells are presented on Figures 2-10. Corrective Action via In situ Bioremediation Injection In accordance with the Corrective Action Plan that was approved by the SWS in a letter dated December 1, 2011, two in situ bioremediation injections have been completed. Phase I consisted of injecting sodium lactate into 5 injection wells upgradient of monitoring wells MW-8, -9, and -10 on June 18-21, 2012. A total of 1,268 gallons of a 10% sodium lactate solution were injected resulting in each well receiving approximately 254 gallons of the sodium lactate solution. Phase I post-injection samples were collected 1, 2, and 5 months after injection. During each sampling event, samples from MW-8, -9, -10, -19, and -29 were analyzed for the following field measurements: pH, temperature, oxidation-reduction potential, dissolved oxygen, conductivity, turbidity, nitrate, sulfate, ferrous iron, carbon dioxide, and alkalinity along with laboratory analyses of chlorides, chemical oxygen demand, VOCs, dissolved gases (i.e. methane, ethane, and ethene), sodium, and total dissolved solids. Volatile fatty acids were also collected during the 1 month post-injection sampling event. Additionally, samples were collected from MW-8, -9, and -10 and analyzed for bacterial population size and functional gene presence during the baseline and 5 month post-injection sampling events. Analytical results for each sampling event are summarized in Tables 4 and 6. Analytical results post-sodium lactate injection for MW-8, -9, and -10 indicated that bioremediation was occurring with no VOCs detected above NC 2L standards in MW-8 or -10, with the exception of 1,1- Ms. Jaclynne Drummond June 27, 2016 Page 7 dichloroethane detected in samples collected from MW-10 in July 2012. MW-9 had detections of 1,1- dichloroethane, tetrachloroethene, trichloroethene, and vinyl chloride above NC 2L standards, but contaminant concentrations were decreasing. DNA analyses revealed healthy populations of bacteria (Dehalococcoides sp) in MW-9 and -10 that continued to reduce contaminant concentrations. Bacterial populations in MW-8 decreased as a result of little to no VOCs being detected during the post-injection sampling. The Phase I injection of sodium lactate successfully caused degradation of trichloroethene and tetrachloroethene to daughter products using enhanced anaerobic bioremediation in the injection area. Although the Phase I injection reduced contaminant concentrations, a second injection was needed to supply a longer lasting source of electron donors. Biodegradation can be sustained for as long as sufficient concentrations of substrate remain in the groundwater. For this reason, emulsified vegetable oil was utilized in the Phase 2 injection as it is a slow-release compound, and therefore should release organic carbon into the groundwater for three to five years, depending on site conditions. During the Phase 2 injection, a 10% emulsified vegetable oil solution was injected into the injection wells on March 25-27, 2013. Injection at each well consisted of approximately 220 gallons of water containing approximately 22 gallons of the emulsified vegetable oil product. The emulsified vegetable oil product consisted of 60% emulsified vegetable oil and 4% sodium lactate by weight, which resulted in a total injection volume of 1,100 gallons of water and 110 gallons of emulsified vegetable oil product. Post-injection samples were collected 1, 4, 7, 10, and 12 months after injection. The April 2014 monitoring event concluded the post-injection monitoring. Analyses for each sampling event were similar to the Phase I events except that a DNA analyses to determine bacterial population size and functional gene presence was only done during the April 2014 sampling event. No VOCs have been detected above the standards in MW-8 since the November 2011 semi-annual sampling event. 1,1-Dichloroethane and an estimated concentration of vinyl chloride were detected above their respective NC 2L Standards in MW-9 during the April 2016 sampling event. The concentration of 1,1,-dichloroethane in MW-9 shows a decreasing trend. MW-10 had concentrations of benzene, 1,1-dichloroethane, vinyl chloride, and an estimated concentration of 1,2-dichloroethane above their respective NC 2L Standards. Benzene and 1,1-dichloroethane show a decreasing trend. No VOCs were detected in samples collected from bedrock monitoring well MW-19 during the April 2016 sampling event with the exception of an estimated concentration of o-xylene below the NC 2L Standard. Historically, VOCs have never been detected above the standards in monitoring well MW-19. MW-29, located at the compliance boundary, has not had any chlorinated ethenes detected above NC 2L Standards since May 2013. No VOCs were detected in samples collected from MW-29 during the April 2016 sampling event with the exception of an estimated concentration of 1,1-dichloroethane below the Ms. Jaclynne Drummond June 27, 2016 Page 8 NC 2L Standard. Concentrations of 1,1-dichloroethane have decreased following the injection events. 1,1-Dichloroethane had been detected below the NC 2L Standard since the January 2014 post-injection sampling event with the exception of the October 2014 semi-annual sampling event (7.2 parts per billion (ppb)) when it was detected slightly above the NC 2L Standard (6 ppb). Dechlorination of chlorinated ethenes from tetrachloroethene to ethene is ongoing. The geochemical data indicates favorable conditions for reductive dechlorination in samples collected from MW-9 and -10 during the April 2016 monitoring event. Healthy DHC populations are present based on the DNA analyses completed in April 2014. Additionally, as expected, concentrations of vinyl chloride have increased in monitoring wells MW-9 and -10. The concentration of ethane has increased in MW-9 and fluctuated in MW-10 following the injection events. Subsequent monitoring events will be evaluated to identify any trends. Recommendations Wake County will continue with the semi-annual assessment monitoring program. All wells will continue to be sampled for Appendix I VOCs plus dichlorodifluoromethane and Appendix I metals plus mercury. Samples collected from MW-2, -8, -9, -10, -12, -13, and -14 will also be analyzed for natural attenuation parameters.

Waste Management Sample Matrix: Project: Client: 04/27/16 - 04/28/16 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 Eighteen ground water samples  were received for analysis at ALS Environmental on 4/27/2016. 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: No significant data anomalies were noted with this analysis. Semi-Volatile Organic Analyses: No significant data anomalies were noted with this analysis. Metals Analyses: ICP/AES results for Vanadium in samples J1603049-(5, 9, and 11) were excessively negative, indicating spectral interference. All associated QC passed parameters. Results should be considered estimated. Method 6020A: Sample(s) J1603049-(1, 2, 4, 8-14) required dilution due to the presence of matrix that interfered with internal standard recovery. The reporting limits are adjusted to reflect the dilution. General Chemistry Analyses: Method SM5210B/405.1: The recovery for Laboratory Control Sample was outside of the control criterion. The analysis could not be repeated because holding time for the test had expired. No further corrective action was possible. Method SM4500-S2 F (Sulfide): The Titrant for this analysis were expired in March 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. Subcontracted Analytical Parameters: An aliquot of the samples were delivered to ALS in Rochester, NY for Organic Acids determination. The certified analytical report has been included in its entirety in this report. An aliquot of the samples were delivered to ENCO in Jacksonville, FL for RSK-175 determination. The certified analytical report has been included in its entirety in Appendix A: Subcontracted Analytical Results. 9143 Philips Highway, Suite 200, Jacksonville, FL 32256 | 904-739-2277 | www.alsglobal.com Approved by Date 5/12/2016 Page 8 of 141 State Certifications, Accreditations, and Licenses Agency Number Expire Date Department of Defense 66206 9/20/2016 Florida Department of Health E82502 6/30/2016 Georgia Department of Natural Resources 958 6/30/2016 Kentucky Division of Waste Management 63 6/30/2016 Louisiana Department of Environmental Quality 02086 6/30/2016 Maine Department of Health and Human Services 2015002 2/3/2017 North Carolina Department of Environment and Natural Resources 527 12/31/2016 Pennsylvania Department of Environmental Protection 68-04835 8/31/2016 South Carolina Department of Health and Environmental Control 96021001 6/30/2016 Texas Commision on Environmental Quality T104704197-16-8 5/31/2017 Virginia Environmental Accreditation Program 460191 12/14/2016 9143 Philips Highway, Suite 200, Jacksonville, FL 32256 | 904-739-2277 | www.alsglobal.com Page 9 of 141 +Possible Tedlar bag artifact.

For your reference, these analyses have been assigned our service request number J1603049. 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 129 of 141 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: J1603049 Project: Feltonsville Landfill _______________________________________________________________________________ CASE NARRATIVE The samples were received intact under chain of custody at the Simi Valley facility on April 29, 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.

CASE NARRATIVE J1603103 Date Received: Service Request: Ground Water Feltonsville Landfill Wake County Solid Waste Management Sample Matrix: Project: Client: 4/28/16 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 Thirteen ground water samples  were received for analysis at ALS Environmental on 4/28/2016. 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 Blank JQ1603518-05 contained a low level of dichloromethane above the Method Detection Limit (MDL), but less than the Method Reporting Limit (MRL). Samples exhibiting dichloromethane in approximately the same concentration as the method blank are flagged with a qualifier to indicate the results are estimated values. The method blank results may indicate the potential for a false positive. 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 300.0 (Nitrate): The analysis of project J1603103 was performed past the recommended holding time due to analyst error. Efforts were made to analyze the sample(s) as soon as possible after problem was identified. However, the analysis of the sample (s) was performed hours past the recommended holding time. The data is flagged to indicate the holding time violation. Method 300.0: The Method Reporting Limit (MRL) for Nitrate for sample(s) J1603103-005 was elevated due to matrix interference from high sample conductivity. Method SM4500-S2 F: The Method Reporting Limit (MRL) for Sulfidefor sample(s) J1603103-(2,5,11) was elevated due to matrix interference. Method SM4500-S2 F (Sulfide): The Titrant for this analysis were expired in March 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.

For your reference, these analyses have been assigned our service request number J1603103. 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 116 of 131 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: J1603103 Project: Feltonsville Landfill _______________________________________________________________________________ CASE NARRATIVE The samples were received intact under chain of custody at the Simi Valley facility on April 29, 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 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.
