Remedial Investigation of the High Explosives Burn Pit Facility, Building 829 Complex, Lawrence Livermore National Laboratory Site 300.

摘要

To assess any impact on the environment resulting from operations at the High Explosives (HE) Burn Pits at Lawrence Livermore National Laboratory (LLNL) Site 300, we evaluated the soil, rock, and ground water beneath the burn pit facility. Between November 16, 1986, and January 12, 1987, we drilled eight exploratory holes; one was converted to a monitor well, and another was converted to a piezometer. Seven holes were drilled, geologically logged, and sampled to determine the concentration and extent of substances that may have infiltrated to the subsurface from the burn pits. The eighth hole was completed as a monitor well but was not sampled, and no detailed log was prepared. Electric logging was performed in one exploratory hole further evaluate the geologic conditions. 27 refs., 4 figs., 6 tabs.
