CH2M Hill Celebrates Cleanup of Another Waste Tank

RICHLAND, Wash.- CH2M Hill Hanford Group hits another goal in tank cleanup at the Hanford site.

CH2M Hill has finished cleanup on a sixth single-shell waste tank.

The 55,000 gallon tank is the third tank they've emptied this year and the fifth in the last 20 months.

The waste was pumped into newer double shelled tanks until it's treated at the Vit plant. 

They used a technology that allowed them to minimize pumping additional water into the tank because they say it's suspected to have leaked.

These new technologies have greatly aided cleanup.

"The pace of retrievals is increasing. We're taking the knowledge that we gain from using these technologies and from the tanks that we complete, and we're applying them to other retrievals," said Erik Olds with the Department of Energy's Office of River Protection. 

Olds says the hardest part was getting started, now that they're moving, they hope to empty another three tanks by the end of next year.
