An ongoing nuclear waste leak in Washington State has rapidly intensified over the past weekend, leaving workers scrambling to pump the waste out of the storage facility. Back in 2011, a leak was found on the inner hull of one of the site’s 28 double-wall storage tanks. The previous leak posed an insignificant threat, but workers came across an even larger leak this weekend while attempting to clear the inner hull of its remaining waste.

Crews at the United States Department of Energy’s storage site in Hanford were alerted by leak detection alarms Sunday morning, and after lowering a camera into the affected area, the staff found 8.4 inches of radioactive and chemically toxic waste had poured between the inner and outer walls of the tank, according to KING 5.
