PFAS (perfluoroalkyl and polyfluoroalkyl substances) in drinking water are a growing concern for the residents of California.  PFAS do not break down easily and accumulate in the environment and in people over time.  Studies suggest that PFAS may be linked to short and long-term health problems.  

PFAS have been used in manufacturing and consumer products in the U.S. since the 1940s, and there are thousands of chemical compounds that are classified as PFA. PFAS are not regulated in drinking water as part of the Safe Drinking Water Act. However, under the Unregulated Contaminant Monitoring Rules, EPA collects data for suspected contaminants in drinking water that do not have health-based standards, including PFAS.

Tracking California has created interactive maps to allow exploration of PFAS monitoring data from EPA.  Our maps show: 

  • Water systems in California were monitored for PFAS in 2013-2015
  • Water systems in California that detected PFAS
  • Sources of PFAS in California
