Field Services Section

The Field Services Section provides support in making water management decisions by collecting, analyzing, and interpreting hydrologic data.  Field Services conducts a wide variety of data collection activities in support of public needs, such as the Assured and Adequate Water Supply and Recharge Programs, Drought Monitoring Program, well drilling and well impact assessments, and in support of hydrologic studies such as groundwater modeling and water budget development through the Statewide Hydrologic Monitoring Program.

This section is comprised of the Basic Data Unit and the Geophysics/Surveying Unit.

Basic Data Unit

The Basic Data Unit is the Departments primary source of groundwater data.  It includes the Statewide Automated Groundwater Monitoring Program and the Groundwater Site Inventory database (GWSI).  Basic Data is responsible for collecting groundwater levels and some water quality data throughout Arizona.


Geophysics/Surveying Unit

The Geophysics/Surveying Unit collects, processes, and interprets gravity, GPS, and Interferometric Synthetic Aperture Radar (InSAR) data for land subsidence and aquifer storage monitoring to help the Department better manage the State’s water resources.  Gravity data is also collected to model depth-to-bedrock for geological framework and water-in-storage projects.
