California Polluted Beaches Maps
Section 303(d) of the Clean Water Act requires states to identify all seriously polluted, or "impaired," water bodies every two years. The states put each polluted water body and its associated contaminants on what they call the "303(d) list." In California, theState Water Board and nine Regional Water Boards maintain and update this list. Thirty-five years after the creation of the Clean Water Act, though, hundreds of California's beaches remain contaminated, and the problem is getting worse. All of the beaches that are listed as impaired on the current 303(d) list are marked with a yellow dot on the map. Select a region to learn more about beach water pollution in your area and where it comes from. The data displayed in these maps is from the last list adopted in 2006. California's Regional Water Boards updated their lists throughout 2008 and 2009. The State Water Board conducted their final review of these lists and adopted the statewide 2008/2010 list of severely polluted waters in August 2010; however, approval of the adopted list by U.S. EPA is pending.
