Soil washing: A promising technology for the cleanup of Hanford

Soil washing is a hazardous waste treatment technology that shows promise for reducing the cost of cleaning up Hanford. The sandy-to-gravelly character of Hanford soil makes the soil a good candidate for the application of the technology. A variety of soil washing vendors offer different approaches to removing contaminants from soil. Factors that must be taken into consideration when selecting soil washing equipment for the Hanford application include properties of the soil and contaminants, cleanup levels required, throughput capacity, secondary waste properties, and cost. Savings of as much as $5000 per ton of contaminated soil may be achievable by using soil washing
