Compass Industries Landfill site is located in Tulsa County, Oklahoma. The abandoned facility, located in a former limestone quarry, was a municipal landfill between 1972 and the early 1980s. During operation, the landfill accepted about 620,000 cubic yards of solid, liquid and sludge wastes, including acids, caustics, solvents and potentially carcinogenic materials. Landfilling activities contaminated soil and groundwater with hazardous chemicals. Following cleanup, EPA took the site off the Superfund program�s National Priorities List (NPL) in 2002.
