DOE to clean up Hanford groundwater
The Energy Department says it's ready to build a $174 million treatment system to clean up some polluted groundwater at the Hanford nuclear reservation.
The Energy Department says it's ready to build a $174 million treatment system to clean up some polluted groundwater at the Hanford nuclear reservation.
The department said Thursday it has committed to the work and signed a record of decision with regulators at the Environmental Protection Agency and state Ecology Department.
The system will require drilling more than 50 wells to pump and treat water from a 5-square-mile plume under the 200 West Area. It's polluted with a solvent that was used in processing plutonium for nuclear weapons. The waste was poured into the ground from 1945 to the early 1970s.
The Tri-City Herald says the pumping is expected to remove 95 percent of the contaminants in the plume in 25 years.
