Abstract
The EPA's Environmental Monitoring and Support Laboratory in Las Vegas, Nevada, is participating in a major geothermal baseline study of the Imperial Valley in California. Statistically based sampling designs have been developed for monitoring elemental levels in soils and crops at the San Diego Gas and Electric/U.S. Energy Research and Development (SDGE/ERDA) Administration Test Facility at the Salton Sea and Known Geothermal Resource Areas at Heber, North Brawley and East Mesa. Samples have been collected at all locations. Analyses of samples collected around the SDGE/ERDA test facility indicate that there are not significant differences in soil residue levels of lithium and manganese between the 50 sites. However, there are significant difference between sites for zinc.
