This report presents a summary of data collected during April and August 1993 and September 1994. These results are to be used as a wet-site analog to southern Nevada soils located at the Amargosa Desert Research Site near Beatty, Nevada. The samples were collected and analyzed in conjunction with the Nevada Basin and Range study unit of the U.S. Geological Survey, National Water-Quality Assessment Program (NAWQA). Samples were collected from groundwater wells in and about the city of Las Vegas, Nevada, and were analyzed for selected major, minor and trace constituents. Analyses of blank and reference samples are summarized as mean and standard deviation values for all positive results.
