Richland, WA - Washington River Protection Solutions, LLC (WRPS), has awarded Freestone Environmental Services, Inc. a subcontract to develop regulatory documents and interpret characterization data in support of Hanford Tank Farm soil investigations. WRPS is the Department of Energy Office of River Protection prime contractor at the Hanford Site and is responsible for safely managing radioactive tank waste and reducing the risk to the environment until it is prepared for disposal. The waste is stored in 149 older single-shell tanks and 28 newer and safer double-shell tanks that are grouped into 18 farms near the center of the 586-square-mile Hanford Site in south-central Washington. There are 56 million gallons of highly radioactive and chemical tank waste material left over from years of World War II and post-war production of nuclear weapons. Historic losses of waste from the tank systems have led to soil contamination in and around the Tank Farms.
As part of interim and final remediation actions for the tank farms, soil contamination associated with the tank farms must be evaluated. Freestone will evaluate historical data and develop detailed plans for obtaining new soil characterization data. The new data will be analyzed and interpreted to develop visualizations and site conceptual models. The conceptual model information will address contaminant sources, environmental setting including historical release information and hydrogeologic data, spatial variability, flow pathways relative to shallow and deep vadose zone contaminant distributions, and associated groundwater contamination. In addition to developing technical and regulatory documents, Freestone will provide WRPS technical support at meetings with DOE, regulators and stakeholders through all phases of the work. With option years the contract may extend through Fiscal Year 2017.
