Topic: Water Quality

Overview

Water Quality

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.

Runoff

Algal Blooms

What are algae?

Organisms that photosynthesize but lack the formal water circulation structure of land plants are placed in the broad category of “algae.” These can grow in either freshwater or saltwater environments, existing as single cells (often congregating in colonies) or multicellular organisms such as giant kelp.

Potable Water

Water from natural sources is treated for microorganisms, bacteria, toxic chemicals, viruses and fecal matter. Drinking raw, untreated water can cause gastrointestinal problems such as diarrhea, vomiting or fever.
