A turning point in the global reckoning over PFAS contamination arrived on June 18, 2025, when the first funds from the landmark 3M and DuPont national water system settlements began flowing to public water utilities across the United States. The settlements—totaling $12.5 billion from 3M and $1.18 billion from the DuPont corporate family—represent the largest environmental contamination settlements in U.S. history and will fund water system testing, treatment infrastructure upgrades, and long-term monitoring at thousands of utilities that documented PFAS contamination attributable to AFFF and other industrial PFAS sources.
The Settlements: Scale and Structure
3M’s $12.5 billion national settlement, which received final court approval in 2024, provides payments over a 13-year period to cities, towns, and public water systems that can demonstrate PFAS contamination from 3M’s PFAS manufacturing or AFFF products. DuPont’s separate $1.18 billion settlement covers claims by public water systems against DuPont, Chemours, and Corteva—the successor entities formed following DuPont’s corporate restructuring. Both settlements are administered through a court-supervised process in the U.S. District Court for the District of South Carolina.
Phase 1 payments—covering water utilities that filed claims by an earlier deadline—distributed approximately 20% of total awards to qualifying utilities as of mid-2025, with additional payments scheduled over the following months. Phase 2 claimants—including water systems that completed baseline PFAS testing after the original claim deadline—must file claims no later than January 1, 2026 to participate. The settlements explicitly cover the costs of PFAS testing and the capital and operating costs of treatment infrastructure, giving utilities a financial pathway to comply with EPA’s MCL requirements for PFOA and PFOS without bearing the full cost burden from rate increases.
New Jersey: $450 Million State-Level Settlement
On May 12, 2025, the New Jersey Department of Environmental Protection (NJDEP) announced a proposed $450 million settlement with 3M to resolve statewide PFAS contamination claims under New Jersey’s Spill Compensation and Control Act. The settlement—structured as payments over 25 years—is intended to compensate New Jersey residents for injuries to natural resources and to fund water treatment projects across the state. New Jersey has some of the highest documented PFAS contamination levels in the eastern United States, reflecting the state’s dense industrial base and its proximity to DuPont’s former Chambers Works facility on the Delaware River, one of the most significant PFAS point sources in American history.
Will the Money Be Enough?
Environmental advocates and water utility executives have raised concerns about whether the settlement funds will cover the actual cost of compliance with EPA’s PFAS drinking water standards. The Natural Resources Defense Council (NRDC) and others have pointed out that the costs of installing and operating granular activated carbon or reverse osmosis systems at the scale needed to serve all affected utilities in the United States—potentially exceeding $50 billion over the life of the MCLs—far exceed the settlement amounts. This gap has intensified advocacy for federal infrastructure funding, and the Biden administration’s Infrastructure Investment and Jobs Act allocated $10 billion specifically for PFAS and emerging contaminant remediation in public water systems.
Implications for Water Treatment Technology Suppliers
The availability of settlement funds—combined with federal infrastructure grants from the Bipartisan Infrastructure Law and state revolving fund allocations—creates the most favorable financing environment for PFAS treatment infrastructure investment in American history. For OEM filter media manufacturers, system integrators, and water treatment technology companies, the practical implication is a multi-year procurement cycle at hundreds of mid-sized and large water utilities as they design, pilot, and install permanent PFAS treatment systems. The dominant technologies in municipal-scale PFAS treatment—granular activated carbon, ion exchange resin, nanofiltration, and reverse osmosis—all require ongoing media replacement and system maintenance, creating recurring revenue streams. Water utilities that receive settlement funds are legally required to spend them on PFAS-related purposes, meaning the capital is earmarked for the specific applications where water treatment suppliers can provide solutions.
