This report documents our investigation of the geology and hydrogeology beneath inactive landfill Pit 9 at Lawrence Livermore National Laboratory (LLNL) Site 300. Site 300 is located about 15 miles east of Livermore, California, in rugged, rural terrain on the east side of the Altamont Hills; this remote facility is used for explosives and materials testing to support LLNL's national defense programs. The landfill is located in San Joaquin County near the center of Site 300. In mid-1988, we began this investigation to determine if ground water quality had been degraded by wastes within the pit. This report presents our results and conclusions. Pit 9 contains potentially hazardous waste generated during explosives experiments. We have assessed the potential impact of landfill Pit 9 vadose zone and ground water chemistry. We have studied the geology and ground water flow characteristics at the Pit 9 site. Ground water flow direction, gradient, and velocities have been determined by well installation and monitoring hydraulic testing. 20 refs., 8 figs., 4 tabs.
