Summary

Requires the EPA to set drinking and surface water quality criteria and pollution limits for PFAS (per- and polyfluoroalkyl substances) and to publish an approved laboratory analytical method. It begins monitoring on enactment, sets specific deadlines for EPA rulemakings (including a January 31, 2026 deadline to promulgate Method 1633A), and authorizes federal grants to publicly owned treatment works (POTWs) and funding to support implementation through FY2026–FY2030.

• Directs EPA to set numeric water quality criteria and effluent limits for PFAS and classes of PFAS.
• Requires EPA to promulgate an approved PFAS analytical method (Method 1633A) by Jan 31, 2026.
• Monitoring requirements become effective on enactment so data collection begins while rules are developed.
• Phases final effluent guideline rulemakings for industry categories with deadlines in 2026, 2027, and 2028.
• Authorizes $200 million per year (FY2026–FY2030) for POTW pretreatment and source monitoring grants (subject to appropriations).
• Authorizes $12 million per year (FY2026–FY2030) to support implementation of other provisions (subject to appropriations).
• Requires EPA to notify Congress when required publications or rulemakings are issued.
• Focuses on both improving laboratory capability and imposing regulatory limits to reduce PFAS in water.
• Creates near-term and multi-year compliance and rulemaking deadlines for EPA, states, dischargers, and labs.
• Authorization of funding does not guarantee appropriation; grants depend on future funding decisions.
