Superfund Site Profile

SITE BACKGROUND

The 66-acre Tri-County Landfill Co./Waste Management of Illinois site is located in Elgin, Illinois. Landfills at the site accepted solid and liquid commercial and industrial wastes from 1961 through 1976. About 4 acres contain fill material. Landfill operations resulted in low-level groundwater contamination outside of the landfill boundaries, contaminated surface water and sediment in an adjacent wetland, and widespread contamination in surface soils at the landfills. Following cleanup, operation and maintenance activities at the site are ongoing.
