This study builds on the 20012002 AB 303 Indian Wells Valley IWV conceptual groundwater model by filling hydrogeologic data gaps, refining the model, and evaluating the groundwater resource as a reliable, long-term source of potable water. Findings support discounting the basin model in favor of a more conventional closed model with recharge principally from Sierra Nevada precipitation, supplemented by sources in surrounding mountains. U Researchers evaluated the following elements geologic conditions along western and southwestern portions of the IWV, vertical and horizontal water quality conditions in areas along the Sierra Nevada, groundwater flow path and travel time from potential recharge areas to extraction areas, and potential degradation of water quality in extraction areas. U Project tasks included installing new monitoring wells in possible recharge areas, collecting water quality and isotopic samples in new and previously sampled wells, interpreting new data and comparing new historical data to determine trends, conducting continuous water-level and water quality monitoring in extraction areas, and making recommendations for improved water management strategies.
