Bayview-Hunters Point Water Hardness & Quality Report (2026)

Bayview-Hunters Point, California, a neighborhood in southeastern San Francisco — a major historically significant San Francisco neighborhood (Bayview-Hunters Point is one of San Francisco's largest and most historically significant African-American communities — a neighborhood shaped by the World War II naval shipyard (Hunters Point Naval Shipyard) that drew thousands of African-American workers from the South, creating one of the most significant Black urban communities on the West Coast), the site of the former Hunters Point Naval Shipyard (a major WWII-era naval dry dock facility — now a Superfund site undergoing remediation and planned for the largest redevelopment project in San Francisco history, the Hunters Point Shipyard mixed-use development), a diverse San Francisco community with a significant Samoan-American and Southeast Asian-American population, and a southeast San Francisco Bay waterfront community — draws its municipal water supply via the San Francisco Public Utilities Commission (SFPUC). Water hardness in Bayview-Hunters Point measures 80.5 mg/L — classified as moderately soft.

Bayview-Hunters Point's moderate softness reflects SFPUC's Hetch Hetchy supply and the southeast San Francisco distribution zone. The Hetch Hetchy Reservoir (O'Shaughnessy Dam — Tuolumne River, Yosemite) drains the Sierra Nevada calcareous-poor Cretaceous granite and metamorphic terrain (virtually no dissolved calcium carbonate). SFPUC distributes through the southeast San Francisco Bayview zone (1940s–1970s Navy-era infrastructure), and moderate mineral accumulation produces the moderate 80.5 mg/L.

With hardness at 80.5 mg/L, Bayview-Hunters Point residents enjoy moderately soft water. SFPUC consistently delivers water meeting all California State Water Board and EPA Safe Drinking Water Act requirements.
