WATER QUALITY
    

The Westborough Water District provides its customers with high quality drinking water that is safe to drink and meets standards set by the California Department of Health Services and the United States Environmental Protection Agency.

The Westborough Water District receives 100 percent of its water from the San Francisco Water Department.  The water comes from Hetch Hetchy in Yosemite National Park and local reservoirs.

The California Department of Health Services and the United States Environmental Protection Agency set standards for drinking water quality. 

The District collects samples throughout the system weekly to be analyzed for coliform bacteria, chlorine residual, pH, and turbidity.  Every three months the District collect samples to monitor for trihalomethanes, or THMs, compounds formed when the chlorine used for disinfection reacts with naturally occurring organic compounds found in water.  Water quality is monitored daily at the Harry Tracy treatment plant by the San Francisco Water Department.
