San Anselmo-Fairfax Patch

In Marin this rainy season, about three million gallons of raw sewage has spilled into the bay according to the watchdog group SF Baykeeper. Sewage spills, large and small, are common in Marin and storm water runoff is a persistent problem, carrying – unfiltered -- everything from heavy metals to pesticide, animal waste, disease-causing bacteria and garbage into our creek system and on into the bay and ocean.
