The 3-acre E. H. Schilling Landfill is located in Hamilton Township in Lawrence County, Ohio. A waste disposal facility operated on site from 1969 to 1980. It accepted liquid and solid hazardous industrial and non-hazardous wastes, including styrene, phenol, acetone, alcohol, wastewater treatment sludges, coal tar compounds and foam material. Waste material was deposited behind an earthen dam and under a soil cover. The State of Ohio closed the landfill in 1980 due to numerous permit violations. Landfill operations contaminated soil, sediment, leachate and groundwater with volatile organic compounds (VOCs), semi-VOCs and metals. Following construction of the site�s remedy, groundwater treatment and operation and maintenance activities are ongoing.
