The State - News from Sept. 4, 1987

Cities and industries in the San Francisco Bay Area are still dumping thousands of pounds of pollutants into the bay estuary each year despite expensive efforts to clean it up, a new study says. The study paid for by the state Water Resources Control Board and the federal Environmental Protection Agency says pesticides, solvents, plastics, petroleum hydrocarbons, phenols, selenium, cyanide and heavy metals are coming from runoff, dredging, spills, air pollutants and plant discharge pipes.
