Superfund Site: OMEGA HILLS NORTH LANDFILL, GERMANTOWN, WI
Superfund Site Profile
The 83-acre Omega Hills North Landfill site is located near Milwaukee in southeast Wisconsin. The landfill accepted hazardous wastes from 1977 to 1982, including heavy metals and solvents. Wisconsin industries used the area for hazardous waste disposal. Large amounts of asbestos have been disposed of at the site. More than 15 million gallons of liquid waste were disposed of at the site each year until the landfill stopped accepting such wastes. The landfill stopped accepting hazardous wastes in 1982 and liquid wastes in 1983. In 1989, the landfill stopped accepting all wastes, and a soil cover was placed over it. Facility operations contaminated soil and groundwater with hazardous chemicals. EPA took the site off the Superfund program’s National Priorities List (NPL) in 1996 because it is being addressed under authorities other than Superfund. Monitoring is ongoing.
