Great Basin Groundwater Arsenic Concentration Map

Maps of Great Basin groundwater geochemistry show distinctive regional spatial patterns. Factors affecting the concentrations of dissolved constituents include bedrock lithology, location within structural zones, geothermal systems, and surficial playa deposits and salt lakes. In this study, a large geochemical database of 51,577 Great Basin groundwater samples from springs and wells was compiled from multiple sources. These data were uploaded into a geographic information system (GIS) and used to produce concentration maps for As, B, Ba, Ca, Cl, F, Fe, HCO3, K, Li, Mn, Mg, Na, SiO2, and SO4. These maps were then examined to identify geologic factors that might have influenced their concentration, including the presence of geothermal systems.
