San Francisco Beach Water Quality

Shoreline bacteria are routinely monitored at sixteen stations around the perimeter of San Francisco where water contact recreation may occur. These include three stations within the Candlestick Point State Recreation Area, one station at Islais Creek, one station at Mission Creek, two stations at Aquatic Park, two stations along Crissy Field Beach, three stations at Baker Beach, one station at China Beach, and three stations along Ocean Beach.

The beach monitoring program is a cooperative effort between the San Francisco Public Utilities Commission and the San Francisco Department of Public Health. Samples are collected weekly year round. Additional monitoring is conducted whenever a treated discharge from the City’s Combined sewer system occurs that affects a monitored beach.
