RE: Landfill Gas Monitoring Report
LFG Monitoring- Monthly Monitoring Event for October 2016
Town of Kernersville Closed Landfill, Permit 34-04
WithersRavenel Project No. 06160093.00
Dear Ms. Drummond:
Attached are a Monthly Landfill Gas Monitoring Report and an Environmental Monitoring Reporting
Form (EMRF) for the monthly monitoring event that was conducted on October 30, 2016 by
WithersRavenel. Inc. at the Town of Kernersville Closed Landfill (Landfill), Permit 34-04. This event
was conducted on behalf of the Town of Kernersville (Town) in accordance with the approved Landfill
Gas Monitoring Plan, dated July 17, 2012.
As in past monitoring events, methane monitoring was planned to be conducted in the eight landfill
gas (LFG) probes located on the Town’s property (designated GW-1 through GW-8) and three LFG
probes shared with the Waste Management Piedmont Landfill (designated GP-9 through GP-11).
Access to the locked security fences and the LFG probes located inside (GW-8, GP-9, GP-10 and GP-
11) was not gained in time to be included with this sampling event.
As shown on the attached Monthly Landfill Gas Monitoring Report, methane gas was not detected in
five of the seven LFG probes monitored on October 30, 2016. Elevated levels of methane gas were
detected in concentrations above the Lower Explosive Limit (LEL) in GW-1 and GW-2R.
WithersRavenel, on behalf of the Town of Kernersville, appreciates the opportunity to submit this
report to the Solid Waste Section. Please contact me with comments, questions, or requests.
Sincerely
WithersRavenel

Mark Brown, LG, PG, RSM
Senior Geologist
