From purpose and scope: The purpose of the National Uranium Resource Evaluation (NURE) program of the U.S. Department of Energy (DOE) is to identify and delineate areas and environments within the Aztec 10X20 Quadrangle, New Mexico and Colorado, that exhibit characteristics favorable for the occurrence of uranium deposits that have the potential to contain at least 100 metric tons U3 08 total endowment with a minimum grade of 100 ppm (0.01 percent) U3 08 . Evaluation is based on geochemical, mineralogic, hydrologic, aerial radiometric, sedimentologic, and general geologic characteristics of the formations in the quadrangle.

From abstract: The High Plains Regional Aquifer System Analysis study has developed a regional water-resources (and related) data storage and retrieval system to organize and preserve areal interpretive data. The system is general and can easily be adapted for other studies. This report documents the High Plains data base as well as the general system that is independent of the High Plains area.

From purpose and scope: The purpose of this study was to estimate the natural streamflow in the Rio San Jose at the upstream boundaries of the Pueblos of Acoma and Laguna. Natural streamflow is defined for this study as the streamflow that would have occurred if water development in the basin upstream from the pueblos had never taken place.

A three-dimensional model was created to estimate vertical hydraulic conductivity and regional ground-water flow rates in rocks within the San Juan Basin in New Mexico and Colorado.

Geothermal fluids of the Ojo Caliente area discharge from a northeast trending normal fault that juxtaposes Precambrian metarhyolite and Tertiary sediments. An electrical resistivity survey shows that the fluids emerge from the fault and flow as a plume of thermal water into cold aquifers east of the fault. Geochemistry of fluids indicates a maximum reservoir temperature at depth of 80/sup 0/C with no suggestion of high temperature isotopic exchange between water and reservoir rocks. From this data, it is believed that the Ojo Caliente system is suitable only for small-scale direct use geothermal applications.

From introduction: The U.S. Geological Survey is participating in this evaluation by developing information on the ground-water hydrology of the region, obtaining geologic borehole data, and conducting hydrologic tests in boreholes on and near the WIPP site. This report provides well-construction information and lithologic data about the Rustler and Salado Formations and the top of the salt interval within the Salado Formation at the H-8 borehole complex.

This report is on the Hells Gate Roadless Area (3-021), Gila County, Arizona.

From Introduction: "The evaluation involved a comprehensive review and synthesis of the geologic literature, knowledge of on-going research, fieldwork, and the work of several geologists with uranium-related experience and knowledge of the rocks in the quadrangle."
