Program plan: Testing of vacuum extraction and in-situ air stripping technologies
Recent hydrological investigations at the Savannah River Plant (SRP) have shown that operation of the plant has resulted in contamination of the groundwater and the vadose zone in various locations across the plant. Volatile organic solvent (VOC) contamination has been observed at a number of locations across SRP. A remedial action program consisting of above-ground air stripping of groundwater is underway to address contamination in M Area. A recent pilot study to clean up the soils above the water table was completed in M Area (for location see Figure 1). A new technique, in-situ vacuum extraction, successfully removed significant quantities of trichloroethylene and tetrachloroethylene from the soils along a portion of the abandoned process-sewer line in M Area. The vacuum-extraction test was conducted for a period of three weeks. It is calculated that almost 1500 pounds of solvents were removed from the soils during the test. The radius of influence for the vacuum process is estimated to be greater than 75 feet. 5 figs.
