(GMA) performed a semi-annual monitoring event at the southern unit of the inactive Pitt County Solid Waste Municipal Landfill (Figure 1) on July 8 and 9, 2015. The work was performed by GMA on behalf of Mr. Phil Dickerson, PE, Pitt County Engineering Department. Twenty-two monitoring wells comprise the groundwater-monitoring network (Figure 1, Table 1). The water-quality monitoring network used for the July 2015 semi-annual monitoring event (Figure 2) consists of two hydraulically-upgradient wells (P4 and P16R), and four hydraulically-downgradient wells (P12, P20R, P28, and MW6R). The hydraulically-upgradient surface water sample location (SW1) and the hydraulically- downgradient surface water sample location (SW2) were also sampled during the monitoring event. Sampling procedures and analytical methods complied with the approved Water Quality Monitoring Plan dated September 8, 1994, and subsequent groundwater policy memos and directives issued by the Solid Waste Section (SWS) of the North Carolina Department of Environmental Quality (DEQ-DWM). 2.0 GROUNDWATER HYDROGEOLOGY Static water levels (Table 2) were measured in all 22 monitoring wells on July 8, 2015. Depth to groundwater ranged from approximately 4.16 to 12.65 feet below the land surface, depending on local elevation at the well and proximity to surface water features. An equipotential map prepared using these water-level measurements (Figure 3) was generally similar to previous maps prepared for this facility, and indicates that the horizontal component of groundwater flow at the southern unit was directed southeastern toward the large ditch forming the southern boundary of the facility. Estimates of groundwater seepage velocity (Table 3) ranged from approximately 0.002 to 0.033 feet/day, or 0.68 to 12.11 feet/year. 3.0 SAMPLE COLLECTION AND LABORATORY ANALYSES The semi-annual monitoring event occurred on July 8 and 9, 2015. Water samples collected from six monitoring wells were analyzed in the field for water-quality parameters during sampling (Table 4). A copy of the well sampling record is provided in Appendix A. Groundwater samples from upgradient wells P4 and P16R, and the equipment and field blanks, were analyzed for Appendix I parameters (Table 5). Groundwater samples from downgradient wells MW6R, P12, P20R, and P28 were analyzed for Appendix II parameters (Table 6). Samples were transferred to Environmental Conservation Laboratories, Inc. (ENCO) in ice-filled coolers under chain-of-custody protocol. Copies of the chain-of-custody forms and analytical reports are provided in Appendix B. July 2015 Semiannual Water Quality Monitoring Report Southern Portion of the Pitt County Solid Waste Municipal Landfill October 2, 2015 Page 2 of 3 4.0 ANALYTICAL RESULTS Four parameters (barium, benzene, chloroform, and ethylbenzene) were detected at concentrations above the Solid Waste Section Limits (SWSLs), and two parameters (barium and benzene) were detected at concentrations above the 15A NCAC 2L groundwater standards (or 15A NCAC 2B surface water standards where appropriate) during this monitoring event (Table 7). Samples from wells MW6R and P16R contained concentrations of barium (799 g/L and 790 g/L, respectively) above the 15A NCAC 2L standard of 700 g/L. The concentrations of barium above the 2L standard in wells MW6R and P16R may be attributable to naturally occurring levels of barium in the native soils at the Pitt County Landfill as has been previously shown (GMA, 2011 and 2015). Previous comparisons of filtered and non-filtered samples from these wells demonstrated that dissolved barium concentrations did not exceed the 15A NCAC 2L standard and that barium was most likely a constituent of the particulate matter at these sampling locations. It should be noted that well P16R is hydraulically upgradient from the southern unit of the landfill, which was the focus of this monitoring event, but is downgradient from the northern unit of the landfill. Barium was also present in well P4, a hydraulically- upgradient monitoring well, at a concentration of 99.7 J μg/L, just below the SWSL of 100 μg/L. The presence of barium in a hydraulically upgradient area further indicates that this alkaline metal may naturally occur in the aquifer. Samples from wells P16R and P20R contained benzene (2.8 g/L and 2.2 g/L, respectively) slightly above the 1.0 g/L 15A NCAC 2L groundwater standard. Well P16R is located hydraulically upgradient of the southern portion of the Pitt County Landfill. 5.0 SCHEDULED SEMI-ANNUAL MONITORING The next semi-annual monitoring event at the Pitt County Solid Waste Municipal Landfill is scheduled for January of 2016. This monitoring event will include the analysis of water samples for Appendix I parameters, per the approved Water Quality Monitoring Plan dated September 8, 1994.

Easley, Governor William G, Ross Jr., secretary RE: Environmental Monitoring Requirements ~ Pitt County Landfill, Northern Portion (Permi! II 74-01) Dear Mr. Dickerson: The proposal submitted by Groundwater Management Associates, Inc. (GMA) on behalf orpin County to stop wuter quality monitoring of the northern portion on the Piu County Landfill has been reviewed. TIle northern portion of th e facilil), is subject to monitoring requirements specified in lSA NCAC 13B .0600. Rule .0601 (a) stales, "The Division shall require a solid waste management facility 10 provide such ground-watcr monitoring capability as the Division detennines to be necessary 10 detect the effects of me facility on ground-water in the area." As statcd in .0601 (a) (t-5), a number of factors can be used in making such a dctemtination. In addition 10 monitoring data, the "type of waste" the landfill accepted, the grolmd-water level in the area, and "uses that are being or may be made of any ground-water" that may have been affected by the facility are all important factors in detennining monitoring requirements. After reviewing these factors, the Solid Waste Section will continue to require limited waler quality monitoring at thc landfill for the following reasons: I. There is increased residential and business development on property adjacent to the facility. Other properties in the general area of the site are also being developed. 2. The landfill is unlined and therefore continues 10 produce leachate that affects groundwater. TIle affected groundwater evcntually moves from beneath the site. 3. The leachate may have contaminants that pose a risk to human health and the environment. 4. Although there is public water available in rhe general area of the landfill, there are a number of potable supp.ly wells within 500 feet of lhe landfill according to the 200 I Hurricane Landfill Assessment Project survey for the NC Department of Environment and Natmal Resources. However a modification of current monitoring requirements wil! be permitted. Beginning this calendar year, the Solid Waste Section WIll allow annual groundwater and surface water monitoring for the northem portion of the Pill County Landfill. 'nle wells and surface water locations will be samplt"d for the same lisl of constituents as have been sampled for in the past. Because the hydraulic gradient in the area is low, groundwater is slow to move and annual sampling should provide adequate detection monitoring for contaminant releases. The south ern portion will continue to be subject to the monitoring requirements of 15A NCAC 138 .1630 through.

Solid waste management rules require thai concentrations of explosive gases, such as methane, not exceed the lower explosive limit of 5% by volume at the property boundary (15A NCAC l3B .0503). Because of the property development adjacent to the landfill there should be documentation that there is no threat to public health from the off-site migration of methane. The only reliable way to insure the detection of methane is to install a permanent methane monitoring system. The bar punch method with temporary monitoring locations that is being used althe landfill is nOI an acceptable method. Therefore the Solid Waste Section is requiring Pin County to install a pemtancnt methane monitoring system along the northern property boundary between the landfill and the adjacent residential property that is being developed. A methane monitoring plan that includes sampling probe construction design, proposed probe locations, and sampling methodology should be submitted to the Solid Waste Section for approval before implementation. A monitoring system installed according to accepted industry standards can provide more accurate and reproducible infonnation and increase the confidence level that protection of public health is being served. Thank you for your cooperation with this important malter. If you have any quesrions, please eaU me at (919) 733-0692, extension 257. Sincerely, d"'~f4,~ Larry Rose Solid Waste section cc: James C.
