RE: SAMPLING AND ANALYSIS PLAN IN RESPONSE TO LEACHATE RELEASE MOORE COUNTY C&D LANDFILL, PERMIT NO. 63-01 ABERDEEN, NORTH CAROLINA
Dear Jackie:
On behalf of Moore County, Golder Associates NC, Inc. (Golder) is submitting this sampling and analysis plan to the North Carolina Department of Environmental Quality (NC DEQ) in response to a leachate release
at the Moore County Landfill that occurred on October 19, 2016. Heavy rains resulted in a leachate breakout from the construction and demolition (C&D) landfill owned and operated by Moore County. The
NC DEQ was notified of the release on October 20, 2016, within the required 24-hour timeframe.
In response to the breakout, the landfill employees blocked off the ditch downgradient of where the leachate
breakout occurred within the limits of waste. The ditch was then excavated below the leachate release area to form a temporary containment trench within the limits of waste to capture the liquid. On Friday
October 21, 2016, approximately 1800 gallons were removed from the trench via vacuum truck and an additional approximately 1200 gallons are currently being stored within the trench. The liquid removed from
the trench was disposed of at the local publicly-owned treatment works (POTW).
Based on site observations, some of the liquid from the release flowed along a ditch along the access road
and discharged to Sediment Pond 2. Site personnel verified that Sediment Pond 2 did not discharge and the liquid was contained within the pond during this event.
Based on information provided by Moore County and under the guidance of the NC DEQ, Golder will collect three soil samples and one surface water sample. Two soil samples will be collected from the bottom of
the drainage ditch along the access road, immediately upgradient of Sediment Pond 2. An additional soil sample will be collected outside the potential area of impact to provide background data for naturally
occurring metals. The proposed soil sampling locations are shown on Drawing 1. The soil samples will be obtained using a hand auger and will be collected between one and two feet below ground surface. The
soil samples will be analyzed for NC Appendix I volatile organic constituents (VOCs) and metals and pH.
A grab surface water sample will be collected from the Sediment Pond 2. The sample will be analyzed for
NC Appendix I VOCs and metals; field parameters including pH, specific conductance, temperature, dissolved oxygen, and oxidation reduction potential will also be collected.
Analysis of the soil and surface water samples will be performed by Environmental Conservation Laboratories, Inc. (ENCO) of Cary, NC. Soil analytical results will be compared to the NC DEQ Inactive
Hazardous Sites Branch, Preliminary Soil Remediation Goals Table’s Preliminary Residential Health-Based Remediation Goals, Preliminary Industrial Health-Based Remediation Goals, and Protection of
Groundwater Soil Remediation Goals. Surface water results will be compared to the NC 2B Standards.
