The research done in FY 1992 at Los Alamos as part of the Hydrology/Radionuclide Migration Project is detailed in this report. We describe our work in support of the Department of Energy defense and environmental restoration programs at the Nevada Test Site. The Appendix of this report lists meetings attended, documents prepared or reviewed, and articles published during FY 1992. We evaluated the extent of tritium concentration gradients in piezometer tubes in hole UE3e[number sign]4 and observed the lack of tritium and [sup 85]Kr in holes UE4t and UE20bh-1. We measured the tritium and fission product distributions as a function of depth in the re-entry hole U4ups2a and collected samples that in-dicate that a large fraction of fission product radionuclides in the water at this site are associated with particulates and are not in solution. We have prepared a history of holes drilled in Yucca Flat that details the effects of water confined at high pressure in certain tuff units there. Our work at the Cambric site is continuing; this year we observed small changes in the concentrations of tritium, [sup 85]Kr, and [sup 137]Cs resulting from the absence of pumping at this site. We analyzed debris from a recent nuclear test to determine the spatial distribution of fission products and their leachability into groundwater.
