About Us

The Community Water Center (CWC) acts as a catalyst for community-driven water solutions through organizing, education, and advocacy. We seek to build and enhance leadership capacity and local community power around water issues, create a regional movement for water justice in California, and enable every community to have access to safe, clean, and affordable drinking water. At CWC, we believe that safe, clean, and affordable water is a human right, not a privilege.

Groundwater is a primary drinking water source for many communities across the state. The Sustainable Groundwater Management Act (SGMA) provides a historic opportunity to protect drinking water supplies and provide other beneficial uses. Now that many Groundwater Sustainability Agencies have finalized their Groundwater Sustainability Plans (GSPs), it is critical to continue building the capacity of disadvantaged and rural community stakeholders to participate in the planning and GSP review process to ensure safe, reliable, and affordable drinking water.

CWC led the development of this tool with research support from UC Berkeley’s Water Equity Science Shop (WESS), Dr. Amanda Fencl and Dr. Rob Gailey, and with feedback from many stakeholders. The core research team developed data layers and through a series of webinars, Advisory Committee members shared feedback throughout the development of the tool. A second iteration of the Drinking Water Tool was released on September 5, 2023. Updates to the tool include refined public and state small water system boundaries, improved domestic well location estimates, updated water quality estimates, and new drinking water threats data layers.

WESS Logo UC Berkeley – Water Equity Science Shop (WESS)

WESS is a community-academic partnership that conducts research and multi-level public health actions to address the health risks associated with drinking water contamination among California residents in rural, agricultural, and socioeconomically disadvantaged communities that are served by small drinking water systems and private domestic wells that fall outside the purview of drinking water regulations and monitoring requirements. The WESS team helped shape and develop this tool, by contributing data on the domestic well community layer, groundwater quality estimation layer, and demographics layer. Learn more about WESS here.
