Abstract |
The E.H. Schilling Landfill site is in Hamilton Township, Lawrence County, Ohio. The site is a 2.7-acre landfill on a larger tract of land. The predominantly rural area neighboring the site includes approximately 50 residences, which are between 0.25 mile and 1.5 miles from the site. The landfill was created by constructing a dam across a small valley. Both the landfill cover and dam have been described as inadequate, and leachate containing hazardous substances is being released through and beneath the dam. From 1969 to 1980 the landfill operators accepted both nonhazardous and hazardous wastes including styrene, phenol, acetone, alcohol, wastewater treatment sludge, coal tar compounds, and cumene. Results from a 1988 investigation reveal that soil and sediment contamination is limited to the area immediately adjacent to the dam, and ground water contamination is limited to the monitoring wells immediately surrounding the landfill and the monitoring wells downgradient of the dam. Contamination appears to be due to leachate runoff. The primary contaminants of concern affecting the soil, sediment, and ground water are VOCs including benzene; other organics including PAHs, pesticides, and phenol; and metals including arsenic. The selected remedial action for this site are included. |
