MCL standards are established by the California State Water Resources Control Board and PHG standards are established by the California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment. The water tests were collected by the San Francisco Estuary Partnership alongside community-based partners and Tribes from around the San Francisco Bay 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. MCLs are adopted as regulations. They are health protective drinking water standards to be met by public water systems. MCLs take into account not only chemicals' health risks but also factors such as their detectability and treatability, as well as costs of treatment. <a href='https://oehha.ca.gov/media/health_saf._code_ss_116365.pdf' target='_blank' rel='nofollow ugc noopener noreferrer'>Health & Safety Code §116365(a)</a> requires a contaminant's MCL to be established at a level as close to its PHG as is technologically and economically feasible, placing primary emphasis on the protection of public health. Additional information on MCLs is provided by the <a href='https://www.waterboards.ca.gov/drinking_water/certlic/drinkingwater/Chemicalcontaminants.html' target='_blank' rel='nofollow ugc noopener noreferrer'>California State Water Resources Control Board's Contaminants in Drinking Water</a> page. A PHG is the level of a chemical contaminant in drinking water that does not pose a significant risk to health. PHGs are not regulatory standards. However, state law requires State Water Resource Control Boards (SWRCBs) to set drinking water standards for chemical contaminants as close to the corresponding PHG as is economically and technologically feasible. In some cases, it may not be feasible for SWRCB to set the drinking water standard for a contaminant at the same level as the PHG. The technology to treat the chemicals may not be available, or the cost of treatment may be very high. SWRCB must consider these factors when developing a drinking water standard. Provides a composit feature set representing locations in the San Francisco Bay Region where tap water test results determined water quality exceeded either Maximum Contaminant Level or Public Health Goal standards. All of the locations have been slightly modified (between 0.5 and 2.5 blocks) to protect the personal information of the 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.
