Superfund Site Profile
The one-square-mile Lawrence Livermore National Laboratory (LLNL) site is an active multi-program research laboratory operated by Lawrence Livermore National Security, LLC, for the U.S. Department of Energy (DOE). Research and support operations at LLNL handle, generate or manage hazardous materials that include radioactive wastes. Facility operations contaminated soil and groundwater with hazardous chemicals. Following initial actions to protect human health and the environment, and construction of the site’s long-term remedy, additional site investigations, operation and maintenance activities, and monitoring are ongoing.
Site 300 was developed in the 1950s as a research facility by the U.S. Atomic Energy Commission, predecessor to DOE, primarily as a high-explosives and materials testing site in support of nuclear weapons research, and is located 15 miles east of LLNL.
