Assessment of the extent of trichloroethylene contamination of soil and water at Lawrence Livermore National Laboratory Site 300
A study has been conducted to determine the extent of trichloroethylene (TCE) contamination of soil and rock and of ground water in the saturated zone at locations of concern at Lawrence Livermore National Laboratory Site 300 located 13 miles southeast of Livermore, California. An exploratory investigation involving surface reconnaissance, geologic mapping, observation and sampling of surface runoff for TCE analysis, exploratory drilling and sampling of soil and rock for TCE analysis, and observation well construction and ground-water sampling for TCE analysis has been completed. The only substantial TCE contamination of soil, rock, and ground water was found in the Building 834 area. A small perched, contaminated ground water body located in a sparingly permeable sand and gravel unit there is isolated from the reional ground-water system by a clay-silt aquitard that largely prevents its downward movement. The perched ground-water body apparently discharges very slowly to the hillside below the Building 834 complex where it evaporates. Small quantities of TCE were also detected in soil and rock samples from the Building 854 area and at Building 830. Building 830 is identified as the most likely source of the TCE found in water samples taken from Spring 3.
