Superfund Site Profile
The H.O.D. Landfill Site is a 51 acre landfill within a 121 acre area in Antioch, Illinois. The area is adjacent to a freshwater wetland and Sequoit Creek, a stream that flows into a series of nearby lakes. The landfill portion is divided into the "old landfill" and the "new landfill." Operations began at the "old landfill" in 1963 and at the "new landfill" in 1975. Following the landfill’s closure in 1984, it was covered with clay. Vinyl chloride-contaminated groundwater is the main risk at the site. The site’s long-term remedy is in place. Operation and maintenance activities and groundwater monitoring are ongoing.
