Book Description
In this report we describe the work done at Los Alamos National Laboratory in FY 1995 for the Hydrologic Resources Management Program funded by the US Department of Energy/Nevada Operations office. Budgetary cuts have required us to scale back our activities, particularly field work at the Nevada Test Site. We have collaborated with a number of government agencies and universities in work related to radionuclide migration through geologic media. In cooperation with Lawrence Livermore National Laboratory, we have demonstrated the utility of high-sensitivity gamma logging and have successfully improved the design of a bailer routinely used for water sampling. We analyzed a suite of side-wall samples from the BASEBALL drill-back and have interpreted the distribution pattern of test-related radionuclides. Though heterogeneously distributed, they show a general separation of volatile and refractory fractions. The distribution pattern suggests that there has been little movement of radioactive material within this cavity, which is 13 years old and below the static water level. This characterization of the BASEBALL cavity/chimney complex may have important implications for radionuclide migration elsewhere at the Nevada Test Site.

Book Description
This report describes the work done at Los Alamos National Laboratory in FY 1996 for the Hydrologic Resources Management Program funded by the US Department of Energy/Nevada Operations Office. Despite declining financial support we have been able to maintain a significant analytical effort because the Underground Test Area Operable Unit at the Nevada Test Site has drilled several wells adjacent to cavities produced by nuclear tests. We measured the radionuclide content in groundwater samples and rock cores taken from near cavities at two sites on Pahute Mesa. At one of these sites we detected plutonium in the groundwater in significant concentrations. Also we detected 137Cs deposition in soils high in a collapsed chimney above the working point at a location in the Low Level Waste Management facility in Area 3 of the Nevada Test Site. We analyzed samples from four wells suspected or known to contain radionuclides. Sampling efforts in wells completed with small-bore tubing or casing continue to be hampered by our inability to adequately purge the well prior to sampling. We presented our work at a number of meetings and published several review articles.

Book Description
This report describes research done at Los Alamos in FY 1993 for the Hydrologic Resources Management Program. The US Department of Energy funds this research through two programs at the Nevada Test Site (NTS): defense and groundwater characterization. Los Alamos personnel have continued to study the high-pressure zone created in the aquifer under Yucca Flat. We analyzed data from a hole in this area (U-7cd) and drilled another hole and installed a water monitoring tube at U-4t. We analyzed water from a number of locations on the NTS where we know there are radionuclides in the groundwater and critiqued the effectiveness of this monitoring effort. Our program for analyzing postshot debris continued with material from the last nuclear test in September 1992. We supported both the defense program and the groundwater characterization program by analyzing water samples from their wells and by reviewing documents pertaining to future drilling. We helped develop the analytical methodology to be applied to water samples obtained in the environmental restoration and waste management efforts at the NTS. Los Alamos involvement in the Hydrologic Resources Management Program is reflected in the appended list of documents reviewed, presentations given, papers published, and meetings attended.
