Site DescriptionThe 80-acre Coshocton Landfill, located in Coshocton County, Ohio, was used for coal strip mining for an extensive period in the mid-1900's. The city built and operated a landfill at the site from 1968 to 1979. In 1977, an area of the site caught fire and burned for three days. Drummed liquid wastes including alcohols, acetone, resins, xylene, perchloroethylene, mineral spirits, plasticizers and neoprene were landfilled at the site. These materials contaminated groundwater, surface water and soils. About 13,400 people live in the city of Coshocton, which is located about three miles from the site. The city water supply is not threatened by the site.
Site ResponsibilityThis site is being addressed through federal and county actions
Threats and ContaminantsGroundwater has been contaminated with volatile organic compounds (VOCs) and heavy metals. Sediments onsite contain VOCs and pentachlorophenol. Soils onsite contain VOCs and phenols. Heavy metals and VOC acetone are found in the surface water. Onsite workers and trespassers may be exposed to hazardous substances if they accidentally ingest or come into direct contact with the contaminated areas.
Cleanup ProgressThe United States Environmental Protection Agency (U.S. EPA) signed a Record of Decision for the landfill in June 1988 which called for capping the landfill and long-term groundwater monitoring. A Consent Decree (CD) between the U.S. EPA and the potentially responsible parties (PRPs) was entered with the court on June 11, 1991. The PRPs designed the remedy, and in 1995-1996, they constructed a cap on the 40-acre landfill. Long-term monitoring is being conducted in order to ensure that contaminants do not leave the site. Low levels of contaminants have been detected offsite. No potable water supplies are currently threatened, but new wells installed down gradient from the site could be threatened. On September 25, 1995, a Preliminary Close Out Report (PCOR) was signed. The Report documented that the response actions were constructed consistent with the approved remedial design, and with the ROD. Groundwater monitoring occurring subsequently to the PCOR documented that contaminants were found below the clean-up levels. For this reason, U.S. EPA, with concurrence from the State of Ohio, deleted this site from the National Priorities List in October, 1998. The first five-year review Report for this site was signed January 21, 1999. The remedy selected remains protective of human health and the environment and complies with Federal and State requirements. The second five-year review was conducted in January 2004. The third five-year review was completed November 2008. The review stated that the remedy was found to be protective of human health and the environment. The next five-year review is scheduled for completion in 2014.
