PFAS poses one of the greatest challenges to the environment and public health in decades. The future is about options and multiple barriers: from drinking water and point-source treatment to waste mini­miza­tion and efficient PFAS destruction. But first, you need to know where to begin. Please use the map below to see your state’s current regulations and guidance or the link to the right to see the latest federal regulations, standards and advisory levels.
New and Noteworthy
On March 14th, 2023, EPA proposed National Drinking Water Standards for six PFAS (PFOS, PFOA, PFNA, PFBS, PFHxS, and GenX) If finalized, maximum contaminant levels (MCLs) would be 4 part per trillion (ppt) for each of PFOS and PFOA. The remaining four PFAS would be regulated as a group, adopting a hazard index approach.
