Lawrence Livermore National Laboratory (LLNL) Site 300 is located in the Altamont Hills between Livermore and Tracy, about 18 road miles southeast of Livermore, California. The site is used as a test facility to support national defense research carried out by LLNL. This Addendum 2 to the Logs of Wells and Boreholes Drilled During Hydrogeologic Studies at Lawrence Livermore National Laboratory Site 300 presents hydrogeologic logs for monitor wells and boreholes drilled primarily between January 1, 1991 and September 1, 1992. Some logs drilled earlier and not incorporated in earlier volumes of this document are also included here. A small number of logs drilled before September 1, 1992, are not available at the time of closing the report for publication of this volume (Addendum 2), but will be included in subsequent documents. By September 1, 1992, a total of 495 monitor wells and 285 exploratory boreholes had been drilled at Site 300 since the beginning of hydrogeologic studies in 1982. The primary purpose of these logs is to document lithologic and hydrogeologic conditions together with well completion information. For this reason, not all chemical analytical data are presented. These logs report concentrations of only the most commonly encountered volatile organic compounds, trace metals, and radionuclides detected in ground water and soil samples collected during drilling.
