The world of PFAS contamination, testing, and regulation has been moving forward at breakneck speed as the U.S. EPA continues to implement its PFAS Strategic Roadmap for 2021-2024. To help Pace^® customers stay up to date, we’re compiling 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).
