Item Information

snippet: All well locations from all datasets standardized on the GAMA Program's Groundwater Information System (GAMA GIS). This is a replacement of previous versions. Authoritative version. WGS 84. All groundwater wells on GAMA Groundwater Information System, accessed April 24, 2023. Sources of data include (as indicated in GM_DATA_SOURCE field): Geotracker: Wells sampled under regulated activities like cleanup and remediation. These are accessible through the California State Water Resources Control Board Geotracker web site. USGS: Wells sampled and analyzed by the U.S. Geological Survey (USGS) through the Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project. GAMA: Wells sampled by California State Water Resources Control Board staff for the GAMA Program Domestic Well Project. DDW: Division of Drinking Water (DDW) wells sampled and regulated for delivered water quality under DDW oversight. DPR: Wells sampled by the Department of Pesticide Regulation (DPR) groundwater program. WDL: Wells in the Department of Water Resources (DWR) water quality sampling network in their water data library. LLNL: Wells sampled for groundwater age, isotopes, or noble gas for the GAMA Program by Lawrence Livermore National Laboratory (LLNL). NWIS: Wells sampled by the USGS and accessible via the National Water Information System (NWIS).UC Davis: Location of wells gathered from multiple local entities for use in the UC Davis Nitrate Report, under agreement with the GAMA Program. LOCALGW: Wells sampled under various local groundwater projects. As of July 30, 2019, this only includes the domestic sampling completed by the Central Coast Regional Water Quality Control Board. ‘ GAMA_LOCALGW: Wells sampled under local groundwater projects, generally sampled from private wells from various private and governmental organizations. Data was submitted through the GAMA Data Connection Portal. The field, GM_DATASET_NAME can also help explain the source of the dataset. Direct any questions to: GAMA@waterboards.ca.gov.
