OSTI ID:10121776
This report contains the results of the chemical analysis of water from springs in Death Valley National Park, California. The springs were selected to represent a variety of aquifers at various flow rates. Nevares, Texas, and Travertine springs are believed to represent carbonate aquifers, whereas the other springs are believed to come from volcanic or valley fill aquifers. Each spring was sampled two to five times between June, 1992 and March, 1994. Samples were collected and analyzed by the Harry Reid Center for Environmental Studies (HRC) Environmental/Analytical Laboratory, at the University of Nevada, Las Vegas. The coordinates and dates of sampling are included. The chemical analyses performed on these spring waters included major cations and anions and trace elements. The analyses for the major anions were performed by atomic absorption (AA) spectrophotometry, the anions by ion chromatography (IC) and the trace elements by inductively coupled plasma-mass spectrometry (ICP-MS). The standard operating procedures (SOP) used for each method are included. It is believed that this is the first effort at such a comprehensive trace element analysis of ground waters. HRC has had to develop, test, and refine sampling and analysis procedures throughout the course of this study. A great deal of effort has gone into ensuring that even with the variations in methods and procedures, the data quality from any one sampling is comparable to the others.
