Data was compiled regarding past and present uses, storage and disposal of hazardous materials at Lawrence Livermore National Laboratory (LLNL), Livermore, California and antecedent site activities. Thirty-two monitor wells were installed at and near LLNL to: (1) provide baseline hydrogeologic data, (2) begin defining the vertical and lateral extent of VOCs in ground water at and west of LLNL and (3) evaluate potential sources of VOCs in ground water at LLNL. Ground water samples were collected and analyzed for VOCs from all new and previously installed LLNL monitor wells and selected private and Alameda County Flood Control and Water Conservation District, Zone 7 wells. Aquifer tests were performed in selected wells to: (1) evaluate vertical hydraulic communication between adjacent shallow and deeper wells, (2) estimate the transmissivity and hydraulic conductivity of water-bearing sediments, (3) estimate ground water flow rates, and (4) assess well efficiency. A technique was developed to collect uncontaminated saturated soil samples from several water-bearing zones in a single borehole. Five wells and four borings were also drilled in the Building 403 area to investigate the presence of fuel hydrocarbons in soil and ground water.
