Geologic and Hydrogeologic Framework of the Espanola Basin: Proceedings of the 4th Annual Espanola Basin Workshop, Santa Fe, New Mexico, March 1-3, 2005: Usgs Open-File Report 2005-1130

Description

This report presents abstracts of technical studies that pertain to the hydrogeologic framework of the Espanola basin, a major subbasin of the Cenozoic Rio Grande rift. Sediments and interbedded volcanic rocks that fill the Espanola basin comprise an aquifer system that is an important source of water for many residents of the basin, including people in the cities of Santa Fe, Espanola, and Los Alamos as well as Native Americans in eleven Pueblos. The abstracts describe results of technical studies that were presented either as poster exhibits or oral presentations at the forth-annual Espanola basin workshop, held March 1-2 of 2005 in Santa Fe, New Mexico. The principal goal of this workshop was to share information about ongoing studies. The Espanola basin workshop was hosted by the Espanola basin technical advisory group (EBTAG) and sponsored by the U.S. Geological Survey, the New Mexico Bureau of Geology and Mineral Resources, and both the Water Research Technical Assistance Office and the Groundwater Protection Program of Los Alamos National Laboratory. Abstracts in this report have been grouped into six information themes: Basic Water Data, Water Quality and Water Chemistry, Water Balance and Stream/Aquifer Interaction, Data Integration and Hydrologic Model Testing, Three-Dimensional Hydrogeological Architecture, and Geologic Framework. Taken together, the abstracts in this report provide a view of the current status of hydrogeologic research within the Espanola basin.
