Characterization of shallow groundwater at TNX

The Savannah River Site (SRS), located on 300 square miles along the Savannah River near Aiken, South Carolina, is owned by the Department of Energy and operated by Westinghouse Savannah River Company. The site''s mission is to support the national security through the production of nuclear weapons material. With the recent reduction of the nation''s nuclear stockpile and the stronger focus on the cleanup of sites where nuclear operations activities have left behind soil and groundwater contamination, identifying and remediating all inactive wastes has become a primary goal.The TNX Area is located adjacent to the Savannah River in the western portion of SRS (Figure 1). The area is a pilot-scale test facility for the Savannah River Technology Center. Pilot-scale testing and evaluation of chemical processes at TNX have included support of the Defense Waste Processing Facility (DWPF), Separations Area, and fuel and target manufacturing areas. Wastewater generated during tests was discharged to unlined basins through a network of underground process sewers.A discussion of waste disposal activities for the TNX Area is included in this report to identify the major sources of contaminants that have impacted the groundwater
