环保署提议废除PFAS饮用水限制
Read, Watch or Listen
The U.S. Environmental Protection Agency has proposed repealing federal drinking water limits for four PFAS chemicals — GenX, PFHxS, PFNA and PFBS — according to a May 19, 2026 announcement. The plan would also grant utilities an additional two years to comply with existing standards for PFOS and PFOA, two of the most studied PFAS compounds. This represents a reversal of the EPA’s 2024 policy that set the first nationwide PFAS drinking water standards, intended to protect an estimated 100 million people. Environmental health organizations and public health experts are now scrutinizing the proposal, citing established scientific links between PFAS exposure and serious diseases.
