Water quality in California is regulated by several state agencies, including the State Water Resources Control Board (State Water Board) and its nine regional boards, which enforce clean water laws and the Department of Public Health.
Water quality concerns are also often involved in disputes over water rights, particularly in situations involving endangered species or habitat.
The State Water Board administers the Clean Water Grant Program that funds construction of wastewater treatment facilities. The State Water Board also issues general permits for municipalities and construction sites that try to prevent contaminants from those sources from entering municipal storm sewers.
Drinking water standards and regulations are developed by federal and state agencies to protect public health. In California, the Department of Public Health administers the federal Safe Drinking Water Act, which regulates drinking water quality in the United States.
Signs at Russian River beaches warning of the potential for harmful blue-green algae in the water were being taken down Thursday, after tests failed to detect the presence of algae-related toxins in recent weeks.
