 Current Water Quality Conditions and Available Test Results PDF

Keller beach is tested for bacterial levels weekly from April to October and twice a month from November to March. This map shows the sample sites across the beach. The East Bay Regional Park District works with the Contra Costa County Environmental Health Department in accordance with California Department of Public Health's "Guidance for Salt Water Beaches" to determine water quality at Keller Beach. Our stop light sign is used to display the relative water quality from our latest bacteriological tests.
