Site investigation: Hydrocarbon leak near Building 403, Lawrence Livermore National Laboratory
A subsurface investigation was conducted in the vicinity of building 403 at Lawrence Livermore National Laboratory to determine the extent of hydrocarbon leakage and contamination of soils surrounding underground storage tanks. The investigation included drilling borings, sampling soils, installing observation wells, sampling ground water from the newly installed and existing observation wells, chemical analyses of the soil and water samples, performing slug tests, performing a surface geophysical study, and performing a biodegradation laboratory study. The results indicate that petroleum products are present in the soils beneath the site. Based on the observed distribution of gasoline contaminated samples, it appears that the source of leakage was located at either the western edge of the southern most tank or the distribution line connected to this tank. Horizontal migration both in the saturated and unsaturated environments is very limited. Separate phase product approximately 6-inches thick is distributed in a parabolic fashion across 50 square feet, with well 403-6 as its apex.
