Title: Sorption studies of VOCs (volatile organic compounds) related to soil/ground water contamination at LLNL (Lawrence Livermore National Laboratory)

Abstract

In 1980, Lawrence Livermore National Laboratory (LLNL) initiated a preliminary ground water study beneath and in the vicinity of the LLNL site in Livermore, California. Findings from that study indicated that volatile organic compounds (VOCs), primarily tetrachloroethylene (PCE) and trichloroethylene (TCE), were present in local ground water. Subsequent sampling results showed several locations with VOCs in the parts-per-billion range, and three areas where parts-per-million concentrations were detected. Subsequently, more than 200 wells were drilled and tested during investigations to assess the lateral and stratigraphic extent of ground water contamination and to understand the hydrogeologic characteristics under the Laboratory and adjacent affected areas. Although PCE and TCE predominate, dichloroethanes, dichloroethylenes, and carbon tetrachloride have been detected in ground water at concentrations exceeding California Department of Health Services recommended action levels. In order to predict the rate and extent of movement of the VOCs in ground water, it is essential to understand the sorptive properties of these compounds in relation to the subsurface soils that exist in this area. TCE and PCE were selected for study initially because of their predominance in the contaminant plume. Additional tests were performed using 1,2-dichloroethane (DCA), 1,2-dichloroethene (DCE), and chloroform (CF). 28 refs., 4 figs., 7more » tabs.« less
