Clean Water

Under the SDWA, the Biden EPA set strict standards and requirements for certain PFAS chemicals in public drinking water supplies. The Trump EPA is delaying compliance deadlines for two of those Biden-era SDWA rules and working to rescind four others.

CWA section 401 governs certification of water quality and provides significant latitude to states to decide how to issue certifications. The Trump EPA proposed a rule to update Section 401 which would limit states’ ability to regulate activities subject to 401 certification.
