California State Water Resources Control Board Division of Drinking Water The California State Water Resources Control Board Division of Drinking Water is the state-level agency responsible for ensuring the safety and reliability of public drinking water systems across California. The division implements and enforces drinking water quality standards derived from federal Safe Drinking Water Act authorities and state statutes administered by the California State Water Resources Control Board and the California Environmental Protection Agency. It works with local county and city health departments, regional water districts, and federal partners to protect public health, manage contamination events, and support water system infrastructure.
The division traces its regulatory lineage to early 20th-century water quality efforts tied to the formation of the California State Water Commission and later the State Water Resources Control Board in 1967. Throughout the 1970s and 1980s, implementation of the Safe Drinking Water Act and amendments such as the 1986 Amendments to the Safe Drinking Water Act shaped California’s approach, alongside state laws like the California Safe Drinking Water Act of 1974. Major events influencing the division include pesticide contamination incidents near San Joaquin Valley, perchlorate discoveries in the Antelope Valley, and the drinking water impacts from the 2007 California wildfires and the 2014–2017 California drought. Partnerships with the United States Environmental Protection Agency, California Department of Public Health (predecessor agencies), and regional water quality control boards have guided its evolution.
The division operates under the administrative authority of the California State Water Resources Control Board and coordinates with the California Environmental Protection Agency and the United States Environmental Protection Agency. Its governance structure includes a central office in Sacramento, California and several district offices aligned with regions such as the San Francisco Bay Area, Los Angeles County, San Diego County, Central Valley, and Sierra Nevada. Leadership roles interface with elected bodies like the California State Legislature and executive offices including the Governor of California. The division works closely with municipal entities such as the Los Angeles Department of Water and Power, San Francisco Public Utilities Commission, Metropolitan Water District of Southern California, and rural systems represented by the California Rural Water Association.
Primary responsibilities include establishing and enforcing maximum contaminant levels in accordance with the U.S. Environmental Protection Agency standards, issuing permits and approvals for public water systems like municipal water systems, community water systems, and non-transient non-community water systems, and overseeing operator certification and training. The division manages responses to contamination events involving substances such as lead, arsenic, nitrate, perchlorate, and emerging contaminants like PFAS. It implements source-water protection programs for watersheds including the Sacramento–San Joaquin River Delta, and provides technical assistance to entities such as the California State Association of Counties and the Association of California Water Agencies.
The division enforces standards developed under the Safe Drinking Water Act and California statutes promulgated through the California Code of Regulations. Regulatory measures include maximum contaminant levels, treatment technique requirements, and monitoring schedules tied to contaminants like coliform bacteria, total trihalomethanes, and disinfection byproducts. Rulemaking processes engage stakeholders including the California Chamber of Commerce, environmental organizations such as the Natural Resources Defense Council and Sierra Club, and academic institutions like the University of California, Davis and Stanford University for technical review. Legal and policy frameworks involve courts including the California Supreme Court when disputes arise over regulatory authority and implementation.
Key programs include the Small Water System Support Program, technical assistance with the Safe Drinking Water State Revolving Fund, asset management initiatives in collaboration with the California Infrastructure and Economic Development Bank, and source protection for watersheds like Mono Lake and the Russian River. Initiatives address resiliency to hazards such as wildfires, earthquakes, and drought impacts seen in the 2012–2016 California drought. The division runs outreach with trade associations like the American Water Works Association and workforce development programs tied to the California Community Colleges and California State University systems for operator certification.
Enforcement tools include administrative orders, civil penalties, and compliance schedules, applied after monitoring data from certified laboratories and reporting by public water systems. Monitoring networks leverage partnerships with agencies like the United States Geological Survey and laboratories accredited by the California Department of Public Health (CDPH) (historical coordination), and response coordination with the California Office of Emergency Services during contamination emergencies. Data transparency efforts publish consumer confidence reports modeled on EPA guidance and engage public stakeholders including county boards of supervisors and tribal governments.
Funding mechanisms encompass federal grants under the Safe Drinking Water Act, state allocations from the Safe and Clean Drinking Water Fund, loans and principal forgiveness through the Drinking Water State Revolving Fund, and bond measures approved by the California State Legislature and voters, including measures similar to statewide infrastructure propositions. Capital assistance coordinates with financing bodies such as the California Infrastructure and Economic Development Bank and local financing districts like community facilities districts and special districts. Investments prioritize upgrading treatment plants, replacing aging distribution lines impacted in cities such as Fresno, Bakersfield, Sacramento, and Redding, and expanding consolidation of small systems to improve public health outcomes.
