Water quality at most Bay Area beaches remains clean and clear, according to a report released Thursday. .Almost all Bay Area beaches have zero or very low levels of bacteria from sewage, agricultural runoff or animal waste during the dry season. In the rainy season, sewage overflows and storm runoff can bring dangerous levels of bacteria to local beaches.
Sewage leaks should start diminishing over the next few years, as 20 Bay Area cities have agreed to meet higher standards for runoff, said Deb Self, director of San Francisco Baykeeper, a pollution watchdog group. "We're making progress," she said. "Right now, some beaches along the bay side pose a public health problem. But within a decade, sewage shouldn't be such big news. We're on the right path."
