> The DOE later found water intruding into at least 14 single-shell tanks and that one of them had been leaking about 640 US gallons (2,400 l; 530 imp gal) per year into the ground since about 2010. In 2012, the DOE also discovered a leak from a double-shell tank caused by construction flaws and corrosion in the tank's bottom, and that 12 other double-shell tanks had similar construction flaws. ...

> In 2007, the Hanford site represented 60% of high-level radioactive waste by volume managed by the US Department of Energy[7] and 7–9% of all nuclear waste in the United States (the DOE manages 15% of nuclear waste in the US, with the remaining 85% being commercial spent nuclear fuel). Hanford is currently the most contaminated nuclear site in the United States and is the focus of the nation's largest environmental cleanup.
