In 1989, the Environmental Protection Agency designated the Oak Ridge Reservation as a Superfund site.
There are three major facilities on the reservation: the Oak Ridge National Laboratory, the Y-12 National Security Complex and the East Tennessee Technology Park (ETTP), which was formerly the K25 site.
According to the EPA, contamination is mostly located in these three areas where the public is not allowed.
The U.S. Department of Energy (DOE) is charged with site cleanup, and the Oak Ridge Office of Environmental Management (OREM) is in charge of the work.
“Our sole mission is to clean up those sites,” Jay Mullis, the manager of OREM.
