Superfund Site Profile
The 90-acre Seattle Municipal Landfill site is located in Kent, Washington, 14 miles south of Seattle. From 1968 to 1986, the City of Seattle leased the site and disposed of refuse on about 60 acres of a 90-acre ravine on a hillside above the Green River. In addition to municipal wastes, the landfill accepted paint residues, industrial sludge and other industrial wastes. Landfill operations resulted in impacts to groundwater and air. The City of Seattle has closed the landfill; operation and maintenance activities are ongoing.
