About Us

The U.S. Department of Energy’s (DOE) Office of Environmental Management (EM) mission is to address the nation’s Cold War environmental legacy resulting from decades of nuclear weapons production and government-sponsored nuclear energy research.  This legacy includes some of the world’s most dangerous radioactive sites with large amounts of radioactive wastes, spent nuclear fuel (SNF), excess plutonium and uranium, thousands of contaminated facilities, and contaminated soil and groundwater.
