  Description:
    Abstract: This data set shows the concentrations of dissolved solids in basin fill aquifers throughout the Southwest Salinity Assessment study area which covers all or parts of Arizona, California, Nevada, Utah, Colorado, and New Mexico. These data were used as part of U.S. Geological Survey Scientific Investigations Report 2006-5315, "Dissolved solids in basin-fill aquifers and streams in the Southwestern United States", by Anning and others.
    Purpose: This data set was developed with the purpose of aiding project scientists with the analysis and display of project objectives.
