On Tuesday, March 14, 2023, USEPA proposed the first-ever National Primary Drinking Water Regulations (NPDWR) for PFAS. In this edition of Pace® News and Views, we provide some thoughts on the proposed rule and catch up on some other important PFAS developments we think should be on everyone’s radar.

We’re less than a month into the new year, and plenty has happened in the world of PFAS contamination and testing . To help Pace® customers stay up to date, we’ve compiled the latest news and developments we think should be on everyone’s radar.

In 2016, the U.S. EPA issued drinking water health advisories (HAs) based on available toxicity data for PFOA and PFOS of 70 ppt, individually or combined. While HAs are non-enforceable, many states used the EPA’s guidance to set state-level rules and regulations. Then, in 2021, the EPA revised its risk assessment for PFOA and PFOS and released draft risk values to the EPA’s Science Advisory Board (SAB).
