The U.S. Environmental Protection Agency (EPA) last week announced a delay of Biden-era regulations on PFAS chemicals in drinking water systems.

Last April, the EPA under the Biden Administration set limits on certain PFAS chemicals in drinking water, requiring community water systems to find alternative water sources or install filtration systems to remove them by 2029.

Now, the EPA is proposing to extend the compliance deadline to 2031 for two of the most common PFAS chemicals – PFOA and PFOS. The agency is also rescinding and reconsidering the limits for four additional PFAS in the initial regulation. 5/14/2025
