RICHLAND, Wash. - Washington Gov. Jay Inslee says tanks at the Hanford site may be leaking some 1,000 gallons of radioactive waste a year.
Inslee said Wednesday the numbers are still being evaluated to determine exactly how much has leaked and how fast the waste is leaving the tanks. The 1,000-gallon number is an estimate based on the early assessment of six problematic tanks.
Hanford has 177 aging tanks that hold millions of gallons of radioactive sludge. Inslee says there is no technology to plug the leaks, so officials are working on a solution to remove the sludge from the leaking tanks. Inslee has also expressed concerns about the other tanks at the site.
Department of Energy officials say they have not found any discernible change in contamination levels in monitoring wells and there is no immediate threat to public safety.
