NBCRightNow.com -- The Department of Energy has released a statement on the 6 leaking tanks at the Hanford site.
DOE says the cumulative rate of seepage from the 6 tanks is estimated to be less than three gallons a day.
"To put that amount in perspective, roughly 1 million gallons of material previously leaked into the soil from the single-shell tanks at Hanford over a period of decades. To address that tanks that were leaking, by 2005, the Department removed all the drainable liquid possible out of the single-shell tanks, into double-shell tanks. We have not observed any discernible change in the contamination levels in the monitoring wells, but continue to monitor it very closely," says DOE spokesperson Lindsey Geisler.
