Drinking Water Well Resources

As California’s climate conditions continue to intensify and become more variable, less snowpack, precipitation, and surface water is leading to an increased reliance on groundwater. DWR supports local agencies in their efforts to improve water supply reliability for Californians and communities who use groundwater wells for drinking water and household purposes through guidance and technical assistance, including the resources found on this page. 

Drinking Water Well Guidance Document and Toolkit

Considerations for Identifying and Addressing Water Well Impacts Cover

DWR developed the Considerations for Identifying and Addressing Drinking Water Well Impacts guidance and technical assistance document to support and assist groundwater sustainability agencies (GSAs) as they implement and prepare for periodic updates of their groundwater sustainability plans (GSPs) to ensure the plans fully consider and appropriately engage drinking water well users during the Sustainable Groundwater Management Act (SGMA) implementation. 

The document provides guidance and technical assistance and various approaches to address impacts to drinking water well users and is also in support of Strategy 6.2 of the Drinking Water Well Principles and Strategies document.

DWR has developed the Considerations for Identifying and Addressing Drinking Water Well Impacts Toolkit, which includes the suite of resources below, as a complementary component to the guidance document. The toolkit includes links to state agency materials, tools, data, and assistance to support local agencies. The guidance document and toolkit are focused on assisting GSAs in implementing SGMA and their local GSPs. GSAs, Counties and Well Permitting Agencies, and well users each have a critical role to ensure the long-term sustainability of groundwater across the State.

Drinking Water Well Principles and Strategies

DWR, in coordination with the Water Board, developed the Drinking Water Well Principles and Strategies in response to Governor Gavin Newsom’s April 21, 2021 State of Emergency Proclamation Action 11. This document now provides a framework of state actions related to groundwater management and drinking water wells.
