CH2M Hill Installing "Umbrella" Over T-Farm

RICHLAND, Wash.- Department of Energy contractor CH2M Hill Hanford Group is taking an interesting step to stop the further spread of radioactive tank waste toward the river.

The plan is to cover a part of the T-farm with the same water proof technology sprayed in truck beds.

Tank T-106 is believed to have leaked more than 100,000 gallons of radioactive waste into the soil, and everytime it rains, rainwater pushes that contamination closer to the groundwater, and closer to the river.

Now, DOE will lay felt the size of a football field down and spray it with something similar to Rhinoliner used in trucks, to waterproof it in the hopes that water won't be able to get to those leaks anymore.

"We'll spray that over the top of where the leak was, and that'll prevent the rainfall just like an umbrella would work, from getting onto that, the material that's below the tanks," said John Kristofzski, who runs the project for CH2M Hill.

They are just testing the process, but if it works there, they're considering doing it in the area of major leaks.

T-Farm is the oldest tank farm on the site.

It's believed to have leaked the most.
