Who sets the water monitoring guidelines for PFAS in water? And how does it work?

In California, the State Division of Drinking Water (DDW) has a “notification level” and a “response level” for water agencies. The City of Paramount follows these guidelines for notifying our customers and other stakeholders.

At this time, the US Environmental Agency has not set a national regulatory limit for PFAS. California’s PFAS regulations are among the most stringent in the nation.
