“In the 1940s, the Manhattan Project leased the National Guard Armory from the State of Illinois for uranium processing and radioactive material storage. In 1951, the site was returned to the State of Illinois.” “Although this site was designated as part of the Formerly Utilized Site Remediation Action Program (FUSRAP) in 1985, the only year in which remediation work took place was 1987.” (Source: Department of Energy)
