What this bill does
H.R. 3888 codifies into federal law the EPA's 2024 final rule setting maximum contaminant levels (MCLs) for six PFAS compounds in public drinking water, including PFOA and PFOS at 4 parts per trillion. It authorizes $4 billion in EPA grants and loans to help water utilities comply with the new standards and creates a PFAS remediation superfund for communities with legacy contamination from military bases and industrial sites.
The bill passed the House 287-138 with significant bipartisan support. Senate companion bill S. 2109 has been introduced by Sen. Tom Carper and Sen. Shelley Moore Capito.
Who benefits
Communities with PFAS-contaminated water — estimated at 200+ million Americans exposed above new federal limits. Rural communities near military bases and industrial sites. Families with children — PFAS exposure is associated with developmental harm, immune suppression, and increased cancer risk. Small water utilities that need federal funding to install filtration.
Who loses / who opposes
Industrial manufacturers who use or have discharged PFAS face increased remediation liability. Some smaller water utilities argue compliance cost will force rate increases for residential customers. PFAS manufacturers including 3M and DuPont have settled major contamination cases but face ongoing liability.
Impact on Black communities
Environmental justice research consistently shows Black and low-income communities bear disproportionate PFAS exposure. A 2021 Nature Communications study found PFAS contamination was 40% more likely in communities with higher proportions of Black and Latino residents, primarily due to proximity to military bases, industrial discharge sites, and aging municipal water systems. PFAS are linked to kidney cancer, testicular cancer, thyroid disease, immune suppression, and adverse birth outcomes — all conditions with elevated rates in Black communities.
