Superfund Site Profile
The 56-acre Adams County Quincy Landfills #2 and #3 site is located five miles east of Quincy in Adams County, Illinois. Private operators ran the landfill from 1967 to 1972, when the City of Quincy leased the landfill from the owner. The city operated the landfill from 1972 to 1978. Site closure, including placement of a final cover, finished in mid-1979. The city purchased the site property in 1982. Refuse, domestic waste and industrial waste were disposed of at the site. The materials contaminated ground water with volatile organic compounds (VOCs). Following cleanup, monitoring of the site’s leachate collection system, ground water quality and the integrity of the landfill cap is ongoing.
