Overview

• The EPA, under the Trump administration, has lifted enforceable limits for PFHxS, PFNA, GenX, and PFBS in U.S. drinking water.
• Compliance deadlines for PFOA and PFOS limits have been postponed from 2029 to 2031, allowing more time for water systems to adjust.
• The agency has abolished its hazard index tool, which assessed cumulative risks from PFAS chemical mixtures.
• Public health advocates warn that over 158 million Americans are exposed to PFAS-contaminated water, with links to cancer, fertility issues, and developmental disorders.
• This regulatory rollback reverses Biden-era standards and aligns with broader environmental deregulation efforts by the Trump administration.
