The Energy Department is committed to a safe, complete cleanup of the environmental legacy of five decades of government-sponsored nuclear weapons development and nuclear energy research. As part of this mission, we safely and cost-effectively transport and dispose of low-level wastes; decommission and decontaminate old facilities; remediate contaminated soil and groundwater; and secure and store nuclear material in stable, secure locations to protect national security.
