Stockton assured thousands of residents [last] week that its tap water is safe to drink despite a foul odor, while residents of a Mountain View neighborhood continue to face boil restrictions weeks after their water supply was contaminated. Stockton’s supplier, the California Water Service, said the odor was caused by a seasonal sourcing shift but that the supply continues to meet safety standards. … Meanwhile, in Mountain View, water samples taken at service lines near homes north of Cuesta Park came back clear of bacteria this week, while a fire hydrant in the affected area tested positive for bacteria and was disconnected from the system, the city said in an update Friday.
