The Groundwater Site Inventory (GWSI) consists of field-verified data regarding wells and springs collected by personnel from the Hydrology Division’s Basic Data Section, the U.S. Geological Survey and other co-operating agencies. The information in GWSI is constantly being updated by ongoing field investigations and through a state-wide network of water level and water quality monitoring sites.
If you are interested in using the GWSI mapping tool, please see the ADWR GWSI Web Application.
