In this report we describe the research done at Los Alamos in support of the Hydrology/Radionuclide Migration Project (HRMP) during FY 1991. Los Alamos personnel have actively participated in HRMP organizational programs and also in US Department of Energy/Nevada Operations Office activities directed toward groundwater protection and environmental restoration. We have presented papers at scientific meetings and published articles in the open literature describing our work at the Nevada Test Site. We have continued our measurement of the spatial distribution of fission products in the cavity/chimney region around expended nuclear tests. The pumping phase of the Cambric experiment ended in August 1991. About 92% of the tritium and 43% of the {sup 88}Kr has moved from the cavity to the pumped well (RNM-2S). We have not detected cations such as {sup 137}Cs in the effluent from RNM-2S. We are continuing to monitor the concentrations of tritium in the piezometer tubes at UE3e{number_sign}4; evidence indicates that there is a large concentration gradient of tritium in one of these tubes. We have performed laboratory experiments with tuff from UE3e{number_sign}4 that lead us to believe {sup 137}Cs did not migrate to that hole by a groundwater transport mechanisms. We have added {sup 99}{Tc} to the list of anions whose elution pattern can be determined in the water pumped from RNM-2S at the Cambric site.
