Tap Water Testing Map Application

This web map application provides tap water testing information for the San Francisco Bay Region. The source data for this application was collected by the San Francisco Estuary Partnership alongside community-based partners and Tribes and includes data on tap water quality from around the region. While the tap water testing project was conducted to provide useful insight into water quality in the region, participants were self-selected. The effort was designed to test the water of those who expressed concern and had a desire to learn more to understand potential issues and their solutions and this effort should not be construed to be a rigorous scientific study. The data for this web map application was collected through a California Department of Water Resources grant that worked with disadvantaged and underserved communities and Tribes to collect data on tap water quality throughout the region in response to distrust in tap water documented during the San Francisco Bay Regional Water Needs Assessment. This tap water testing effort was envisioned and implemented by the community and Tribal partners that the San Francisco Estuary Partnership worked with during the Regional Water Needs Assessment Process and was supported technically and programmatically by the San Francisco Estuary Partnership, UCLA Luskin Center, Woodard and Curran, and Lotus Water. All of the locations have been slightly modified (between 0.5 and 2.5 blocks) to protect the personal information of the project participants. Community partners involved in the water testing project were All Positives Possible, Brower Dellums Institute for Sustainable Policy Studies and Action, California Indian Environmental Alliance, Contra Costa Resource Conservation District, First Generation Environmental Health and Economic Development, Friends of Sausal Creek, Marin City Climate Resilience and Health Justice, Mujeres Empresarias Tomando Acción, Multicultural Center of Marin, Nuestra Casa de East Palo Alto, Sonoma Ecology Center, and The Watershed Project.
