This letter report presents the results of the most recent semi-annual sampling event and constitutes the first semi-annual sampling event for 2016. The approved groundwater monitoring network consists of one background well (i.e. MW-1), and ten downgradient monitoring wells (i.e. MW-2, -3, -4S, -4D, -5, -6, -7, -8, -9, and -10). Field activities and sampling results are discussed below. Background The East Wake Landfill (landfill) is located on two parcels. One of the parcels as shown on Figure 1 is owned by Carolyn Properties, LLC and contains approximately 27 acres of waste. This parcel is referred to as the J.T. Knott property and is currently part of the North Carolina Department of Environmental Quality’s Inactive Hazardous Sites Pre-Regulatory Landfill program. The background monitoring well for the portion of the landfill located on the James Ervin Rigsbee (Rigsbee) property, MW-1, is located on this parcel along with a private airport and several businesses. The parcel owned by Mr. Rigsbee contains approximately 46 acres of waste located in two separate areas as shown on Figure 1. This parcel borders the J.T. Knott property to the south and west. A large portion of the parcel is used as a cattle pasture and includes an explosive storage company and associated storage and office trailers, a home with a detached garage and two barns, and a storage area for abandoned automobiles. All monitoring wells for the landfill, with the exception of the background well, are located on this parcel. This portion of the landfill operated under Permit Number 92-02 until the two waste disposal areas ceased operations in 1983 (Area C) and 1985 (Area D). Ms. Jaclynne Drummond June 27, 2016 Page 2 The two areas of waste located on the Rigsbee property are known as Areas C and D as shown on Figure 1. Groundwater assessment for Area C is expected to fall under the supervision of the Inactive Hazardous Sites Pre-Regulatory Landfill Unit (Unit) after this area of waste was determined to be eligible for the program in the fall of 2012. The County will continue the semi-annual monitoring program for Area C until the Unit finalizes its assessment of groundwater. Field Activities Groundwater samples from the landfill monitoring wells were collected on May 5, 2016. All samples were collected by use of disposable, laboratory decontaminated bailers. Monitoring well sampling locations are presented 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 potentiometric contours for this sampling event and are presented on Figure 1. The groundwater elevations and potentiometric contours were used to estimate the groundwater velocity at each well. Groundwater velocity values are provided in Table 3. 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 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. Wells that had elevated turbidity were allowed to stabilize prior to sample collection. The water quality parameters at the time of sampling are presented in Table 2. Sampling Results ALS Environmental, Inc., located in Jacksonville, Florida, analyzed the groundwater samples for the North Carolina Appendix I volatile organic compounds (VOCs) and metals. 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 well locations for the 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. Some monitoring wells had “B” flags, indicating that the analyte was found in the associated method blank as well as in the sample. MW-4D had an estimated detection of vanadium that had excessively negative results, indicating spectral interference. This detection is indicated by a “UX” flag. The following list indicates the analytes detected above the MDL at each sampling location (Area C and D monitoring wells). No “J” flag detections are provided. Underlined analytes exceeded the 15A NCAC 02L .0202 (NC 2L) Groundwater Standard or Groundwater Protection Standard. A complete summary of all detected and estimated concentrations for the May 2016 sampling event is provided in Table 4. The laboratory analytical data report is provided in Appendix A.

The “J” flag constituents above the standards along with their locations are listed below. Cobalt: MW-1, -5, -6, -7, and -8 Thallium: MW-1, -4S, -5, -8, and -9 Vanadium: MW-1, -2, -4D, -5, and -7 Acetone, toluene, and copper were detected as estimated concentrations in the equipment blank below their respective NC 2L Standard. Toluene was detected as an estimated concentration in the trip blank below the NC 2L Standard. The duplicate sample, identified as MW-5 dup, was collected from MW-5. With the exception of an estimated detection of vanadium above the NC 2L Standard in MW-5, there were similar analyte concentrations as those detected in MW-5 dup. Table 5 presents a summary of all parameters detected during the May 2016 sampling event that exceeded the NC 2L or Groundwater Protection Standards. The County will continue with the semi-annual groundwater monitoring program. The next sampling event will take place during the fall of 2016.

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 Fourteen ground water samples  were received for analysis at ALS Environmental on 5/6/2016. 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 JQ1603723-05 contained a low level of toluene above the Method Detection Limit (MDL), but less than the Method Reporting Limit (MRL). Samples exhibiting toluene 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. Metals Analyses: The result should be considered estimated for Vanadium analyzed by ICP/AES in sample(s) J1603309-005. This sample had excessively negative results, indicating spectral interference. 9143 Philips Highway, Suite 200, Jacksonville, FL 32256 | 904-739-2277 | www.alsglobal.com Approved by Date 5/19/2016 Page 2 of 62 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 3 of 62 +Possible Tedlar bag artifact.
