  • Summary of the Southwest Alluvial Basins Regional Aquifer-System Analysis in parts of Colorado, New Mexico, and Texas by D.W. Wilkins (Professional Paper 1407-A). The main purposes of the SWAB study were to enhance the understanding of the regional hydrology of alluvial basins that serve as major groundwater reservoirs, and to study the hydrologic effects of stresses on the system. The report summarizes studies of 22 selected alluvial basins and discusses water quality, groundwater flow systems, and water use in the study area as a whole. Geology, groundwater flow, groundwater geochemistry, groundwater recharge, and aquifer characteristics were studied, and digital flow models of the groundwater systems were developed for three basins.
  • Detailed study of selenium and selected constituents in water, bottom sediment, soil, and biota associated with irrigation drainage in the San Juan River area, New Mexico, 1991-95 by Carole L. Thomas, R. Mark Wilson, Joel D. Lusk, and R. Sky Bristol (USGS Water-Resources Investigations Report 98-4213). In response to increasing concern about the quality of irrigation drainage and its potential effects on fish, wildlife, and human health, scientists from the USGS, U.S. Fish and Wildlife Service, Bureau of Reclamation, and Bureau of Indian Affairs collected water, bottom-sediment, soil, and biological samples at 61 sites in the San Juan River area during 1993-94. Supplemental data collected in 1991-1995 by the Bureau of Indian Affairs extended the time period and sampling sites available for analysis.
