CH2M Hill Cleans Out Seventh Single-Shelled Tank

RICHLAND, Wash.- Cleanup work is complete on another of the Hanford site's 149 single-shelled tanks.

It's the seventh that's been completed, and more waste was removed from tank S-112 than all others combined.

More than 600 thousand gallons of radioactive waste was removed since the project began in 2003.

The waste is being treated and transferred to less leak prone double-shelled tanks.
