(CDM Smith), on behalf of Wake County, is submitting an electronic copy of the March 2016 semi-annual sampling event report. This letter report presents the results of the most recent semi-annual sampling event at the North Wake C&D Landfill and constitutes the first sampling event for 2016. The approved groundwater monitoring network consists of the background well (i.e. MW-1) and three down gradient compliance wells (i.e. CD-1, -2, and -3). Field activities and results of the March 2016 sampling event are discussed below. Field Activities Groundwater samples from the North Wake C&D Landfill were collected from March 24-25, 2016, by use of disposable, laboratory decontaminated bailers. Monitoring well locations for the North Wake C&D Landfill are shown on Figure 1. Well construction details are provided in Table 1. Groundwater elevations were measured at each well prior to sampling and are presented in Table 2. These groundwater elevations were used to construct a potentiometric surface map for this sampling event. The potentiometric contours are shown on Figure 1. 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 was measured 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. Monitoring wells with elevated turbidity were allowed to stabilize prior to sample collection. The water quality parameters at the time of sampling are presented in Table 2. Ms. Jaclynne Drummond June 24, 2016 Page 2 Sampling Results ALS Environmental, Inc. located in Jacksonville, Florida, analyzed the groundwater samples for North Carolina Appendix I volatile organic compounds (VOCs) and Resource and Conservation Recovery Act metals (i.e. arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver). In accordance with 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 for the C&D Landfill had detections of analytes above the MDL but below SWSLs. These detections were qualified as estimated or “J” flags. No Appendix I VOCs or metals were detected above the 15A NCAC 02L .0202 (NC 2L) Groundwater Standards. Equipment and trip blanks were analyzed for quality control. The equipment blank had estimated detections of 2-butanone and acetone below their respective NC 2L Standards. An estimated concentration of methylene chloride was detected in the trip blank below the NC 2L Standard. A complete summary of all detected and estimated concentrations for the March 2016 and previous sampling events is presented in Table 3. The laboratory analytical data report is provided in Appendix A. CDM Smith will monitor future analytical results to determine if a trend appears. The next semi-annual sampling event will be completed in the fall of 2016. If you have any questions or require further explanation, do not hesitate to call me at (919) 325-3500.

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 Six ground water samples  were received for analysis at ALS Environmental on 3/26/2016. 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 JQ1602476-05 contained a low level of dichloromethane above the Method Detection Limit (MDL), but less than the Method Reporting Limit (MRL). Affected samples 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. 9143 Philips Highway, Suite 200, Jacksonville, FL 32256 | 904-739-2277 | www.alsglobal.com Approved by Date 4/5/2016 Page 2 of 45 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 T104704197-15-7 5/31/2016 Virginia Environmental Accreditation Program 460191 12/14/2016 9143 Philips Highway, Suite 200, Jacksonville, FL 32256 | 904-739-2277 | www.alsglobal.com Page 3 of 45 +Possible Tedlar bag artifact.
