Superfund Site: KERR-MCGEE (REED-KEPPLER PARK)
WEST CHICAGO, IL
Superfund Site Profile
The Kerr-McGee (Reed-Keppler Park) site is one of four Superfund National Priorities List (NPL) sites in the West Chicago area contaminated with radioactive thorium wastes. The radioactive waste came from a nearby facility known as the Rare Earths Facility (REF). The REF, operated by Lindsay Light and Chemical Company and its successors from 1932 until 1973, produced non-radioactive elements known as rare earths and radioactive elements such as thorium, radium and uranium along with gas lantern mantles for private entities and federal atomic energy programs. Following cleanup, EPA took the site off the NPL in February 2010.
