Superfund Site Profile
The 26-acre Sparta Landfill site, located in Kent County, Michigan, is a closed municipal landfill. About 12 acres of the site operated as an open dump (Schwab Dump) from the 1940s to 1972, accepting general, residential, commercial and solid wastes. In 1972, Kent County began operation of the Sparta Landfill on property adjacent to the Schwab Dump and acquired the Schwab Dump property in 1973. In 1977, the landfill was closed and a two-foot sand cover was placed over the site. In 1979, the Michigan Department of Natural Resources (MDNR) detected volatile organic compounds (VOCs) in on-site monitoring wells. Organic solvents were also detected in nearby residential wells. Kent County replaced four residential wells. Following construction of the site’s long-term remedy, operation and maintenance activities and monitoring are ongoing.
