Water Quality

The Estero Municipal Improvement District purchases treated water from the San Francisco Water Department and distributes it to Foster City and parts of San Mateo. The District monitors water quality to ensure that it meets state and federal drinking water quality standards.

The San Francisco Water Department also maintains web pages that contain information on cryptosporidium, lead and copper, water quality fact sheets, Annual Water Quality Reports, other reports and links to other web sites.
