Superfund Site Profile
The Ellisville Superfund Site is located in west St. Louis County, Missouri, about 20 miles west of downtown St. Louis. The site includes three nearby detached subsites: Bliss-Ellisville, the Callahan property and the Rosalie property. During the 1960s and 1970s, the Bliss Waste Oil Company transported and disposed of waste oil products, industrial wastes and chemical wastes. The company disposed of these wastes in pits and drums, as well as on the ground at the 11-acre Bliss property, the eight-acre Callahan property, and the 85-acre Rosalie property. Site investigations discovered soil contamination at the Bliss, Callahan and Rosalie properties. EPA placed the site on the Superfund program’s National Priorities List (NPL) in 1983. Cleanup workers removed and disposed of contaminated soil and drums, and then backfilled, capped and reseeded the excavated areas to control erosion. Groundwater monitoring continues at the Bliss subsite.
