An underground tank in Washington is leaking gallons of radioactive chemical waste

An underground radioactive chemical storage tank in southeast Washington state is leaking gallons of nuclear waste, the Washington State Department of Ecology, which is overseeing the site's cleanup, reported Thursday.

The 75-year-old tank B-109 at Hanford Nuclear Reservation is estimated to be leaking 3.5 gallons of waste a day into the ground, which equates to nearly 1,300 gallons per year. "This highlights the critical need for resources to address Hanford's aging tanks, which will continue to fail and leak over time," Washington DOE Director Laura Watson said in a statement.
