The U.S. Department of Energy (DOE) has one of the richest and most diverse histories in the federal government.May 14, 2025
Why DOE’s Environmental Legacy Missions are Critically Important
The U.S. Department of Energy is committed to managing its responsibilities associated with the legacy of World War II and the Cold War. This legacy includes radioactive and chemical waste, environmental contamination, and hazardous material at more than 100 sites across the country.
The atomic legacy of these nuclear programs resulted in trillions of liters of contaminated groundwater; millions of cubic meters of soil and debris contaminated with radionuclides, metals and organics; 90 million gallons of radioactive liquid waste; 700,000 metric tons of depleted uranium; more than 5,000 contaminated facilities; billions of gallons of contaminated groundwater; and 2,450 metric tons of heavy metal of spent nuclear fuel. The Department has taken major steps toward fulfilling our commitments to clean up this environmental legacy and manage post-closure responsibilities.
Environmental Management and Legacy Management are responsible for cleaning up, monitoring safety, and maintaining records at these sites.
