California State Water Board Updates Guidelines for Testing & Reporting PFOA and PFOS

On August 23, 3019, the California Water Board updated their guidelines for drinking water testing and reporting PFOA and PFOS 

To access their Media Release, please click here.

The State Water Resources Control Board today announced their updated guidelines for local water agencies to follow in detecting and reporting the presence of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) in drinking water.  In addition, the Water Board announced it has begun the process of establishing regulatory requirements or maximum contaminant levels for PFOA and PFOS.  They may also add other PFAS compound in the future.

The updated state guidelines lower the current Notification Levels in drinking water from 14 parts per trillion (ppt) to 5.1 ppt for PFOA and from 13 ppt to 6.5 ppt for PFOS.

With this change, California has established the strictest Notification Levels for PFAS substances in the U.S.

Notification Levels are a non-regulatory, precautionary health-based measure for concentrations in drinking water that warrant notification and further monitoring and assessment. Water Systems which find PFOA or PFOS in exceedance of the Notification Levels are required to report these to their governing board, the Water Board and are urged to report this to their customers.

AB 756, signed by Governor Newsom on July 31, authorizes the State Water Board to more broadly order water systems to monitor for PFAS and report their detections. Additionally, drinking water sources with PFAS levels that exceed the response level are either to be taken out of service or the water system must provide public notice of the exceedance level. The law takes effect January 1, 2020.

The State Water Board is currently conducting a statewide assessment to determine the scope of contamination by PFAS, including PFOA and PFOS, in water systems and groundwater.
