Data and Databases - Groundwater

This topic includes ambient groundwater level and groundwater quality sampling data throughout California, well construction information for regulated sites, and a range of information and sampling data for sites that impact groundwater or require cleanup to protect groundwater resources.

Groundwater Monitoring

  • GeoTracker Groundwater Ambient Monitoring and Assessment Program (GAMA)

    The GeoTracker GAMA system consists of groundwater sampling data and water level information. Well construction details are also available for State and Regional Water Boards (collectively Water Boards) regulated sites. Dataset categories included in the system have been integrated from various state and federal agencies responsible for collecting groundwater information, and private groups who have requested to include their data in the system. The GeoTracker GAMA displays water quality data from various sources on an interactive Google-based map, and is searchable by chemical or location. For assistance, please contact the Help Desk at GAMA@waterboards.ca.gov or 916-341-5577.

Groundwater Related Facilities

  • Cleanup Sites By County (GeoTracker)

    GeoTracker is a data management system for managing sites that impact groundwater, especially those that require groundwater cleanup (Underground Storage Tanks, Department of Defense, Site Cleanup Program) as well as permitted facilities such as operating USTs and land disposal sites. It includes portals to retrieve records and view integrated data sets from multiple State Water Board programs and other agencies through a Google maps GIS interface, and provides most of the public record for a site (including regulatory communication with responsible parties, regulatory actions such as records of decision documents, and all data and documents submitted by the responsible party) through its Document Manager Module. For general assistance in searching or utilizing the GeoTracker database, please contact the GeoTracker Help Desk at geotracker@waterboards.ca.gov or 866-480-1028.
