Meyers Landfill Oversight
AMSET is providing hydrogeologic technical assistance and Level III Contracting Officer Technical Representative (COTR) support for the on-going investigation and remediation of the closed Meyers Landfill, located on Forest Service land in the Lake Tahoe Basin Management Unit (LTBMU). The landfill which operated for many years under a Special Use permit was closed in the early 1970's. The landfill generated leachate which impacted surface and groundwater. Leachate flowing at ground surface was eliminated, but groundwater continues to be impacted by leachate from the waste. The Forest Service, and El Dorado County are working to determine the extent of impacted groundwater and select appropriate remediation measures. An impermeable cap has been installed over the landfill to prevent infiltration of precipitation, which is producing leachate and impacting groundwater. On-going groundwater monitoring will determine the effects of the landfill cap and what groundwater remediation may be required.
AMSET is providing technical expertise in groundwater contamination investigation and remediation as the Project Coordinator to move the project forward through the CERCLA process. AMSET is interacting with contractors, responsible parties, and Forest Service staff, reviewing and commenting on technical documents, providing oversight for landfill cap construction and groundwater investigation field activities, and coordinating contractor and Forest Service activities.
AMSET is also providing technical expertise to the Contracting Officer (CO) as the COTR by preparing scopes of work, reviewing proposals and contract modification documents, assisting with contractor selection, and providing inspector services.
