Superfund Site Profile
The 114-acre Waste Disposal Engineering site is located in Andover, Minnesota. The site includes a 73-acre landfill that operated from 1968 to 1983. The landfill accepted around 2.4 million cubic yards of municipal, commercial and industrial wastes. From 1972 to 1974, hazardous wastes were disposed into a pit in the landfill. Waste disposal operations contaminated groundwater with hazardous chemicals. Area residents rely on groundwater for their drinking water source; however, water supply wells are not impacted by the landfill. Following cleanup, EPA took the site off the Superfund program’s National Priorities List (NPL) in 1996. Operation and maintenance activities are ongoing under the Minnesota Pollution Control Agency (MPCA) Closed Landfill Program.
