"They thought they'd managed this problem a few years ago. But Washington state Gov. Jay Inslee got a disturbing call Friday from Energy Secretary Steven Chu: Nuclear waste is leaking out of a tank in one of the most contaminated nuclear waste sites in the U.S."
"Inslee released a statement, saying a single shell tank at Hanford Nuclear Reservation is slowly losing between 150 and 300 gallons of radioactive waste each year. All of the liquid was removed from the tank in February 1995; what's left is toxic sludge. Inslee said 'Fortunately, there is no immediate public health risk. The newly discovered leak may not hit the groundwater for many years, and we have a groundwater treatment system in place that provides a last defense for the river. However, the fact that this tank is one of the farthest from the river is not an excuse for delay. It is a call to act now.'"
