How safe is Bay Area drinking water from ‘forever chemicals’? – San Francisco Chronicle
The Bay Area’s drinking water generally has low levels of PFAS because large water systems in the region get most of their supply from pristine sources in the Sierra or local reservoirs in regional parks, according to researchers who study toxic chemicals in drinking water. The city of San Francisco, for instance, gets most of its water from Hetch Hetchy, a reservoir north of Yosemite Valley.
