Hanford Workers Continue to Remove Contaminated Dirt

Posted: Updated:

 

RICHLAND, Wash. - Workers at Hanford are continuing to remove contaminated soil on the nuclear reservation. 

Dump trucks started moving about 400 loads of dirt every day back in December. By August, workers say they expect to have an 85-foot deep hole, that stretches from the length of a football field on the bottom, to more than seven football fields at ground level.

Hanford says the soil contains a chemical that functions as a corrosion inhibitor in cooling water for the reactors. Employees say the chemical leaked into the soil, causing toxic chromium in groundwater that could potentially reach the Columbia River.
 
Workers are bringing the soil to a landfill, and plan to fill the hole with clean dirt.
