Description: Well locations, grid cell boundaries, and study unit boundaries for both the public supply and domestic supply assessments of the Priority Basin Project. The Priority Basin Project is led by the U.S. Geological Survey through cooperation with the California State Water Resources Control Board, legislatively mandated by AB 599 (Liu), 2001 (Groundwater Quality Monitoring Act of 2001, Water Code Sections 10780-10782.3). The Priority Basin Project, started in 2002, provides a comprehensive assessment of statewide groundwater quality that helps identify and understand the risks to California's groundwater resources. The project assesses both deep and shallow groundwater resources through statistically reliable sampling methods. The State Water Board is collaborating with the U.S. Geological Survey (USGS) and Lawrence Livermore National Laboratory (LLNL) to implement the Priority Basin Project. The project consists of two phases: The Public Supply Assessment focuses on assessing deep groundwater resources for public drinking water systems. The initial Public Supply Assessment baseline of 35 study units was completed from 2004 to 2012 and 5-year trend sampling is ongoing. The Shallow Aquifer Assessment focuses on assessing the quality of groundwater in shallow aquifers used by small systems and domestic wells. The Shallow Aquifer Assessment baseline began in 2012 and is ongoing. The Priority Basin Project helps reach the main GAMA Program goals by providing an assessment of current groundwater quality, identifying the natural and human factors affecting groundwater quality, detecting changes in groundwater quality over time, and providing the data to be included in the GAMA Groundwater Information System (GAMA GIS).
