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.

The Arizona Department of Water Resources Hydrology Division's Geophysics/Surveying Unit has been collecting and processing Interferometric Synthetic Aperture Radar (InSAR) data since 2002 to monitor land subsidence across the State of Arizona. Statewide land subsidence features were identified using the ERS-1, ERS-2, Radarsat-1, EnviSat, ALOS-1, ALOS-2, Radarsat-2, and Sentinel-1 Satellites and are updated to 2026. This data contains spatial extent of the Arizona land subsidence features as of May 2026 and is created to serve as base information for use in GIS systems for a variety of planning and analysis purposes.
