This week brought a signal that anyone watching PFAS policy should take seriously. The White House Office of Management and Budget released two EPA rule proposals back to the agency — one extending compliance deadlines for PFOA and PFOS maximum contaminant levels by two years, and another formally rescinding regulations for PFHxS, PFNA, PFBS, and HFPO-DA (GenX). EPA is expected to publicly announce these proposals in the coming days.
The message from Washington is clear: federal enforcement of the 2024 PFAS drinking water standards is slowing down. But the contamination isn't.
800 Times Over the Limit in Wisconsin
In Wausau, Wisconsin, an April 2026 site investigation report for 3M's Greystone facility confirmed what residents have feared for years. Groundwater samples collected in late 2025 showed PFOA levels of 3,200 nanograms per liter — 800 times higher than the 4 ng/L limit proposed by Wisconsin's Department of Health Services.
The contamination traces back decades. 3M used PFAS-laden groundwater for dust suppression at the Greystone quarry, spreading contaminated material across the surrounding area. Now, roughly 800 residents in the Village of Maine live within five miles of the site. Attorneys held an informational session in early May, advising anyone who used 3M fill material or lives near the quarry to take immediate precautions.
This is what PFAS contamination looks like at the local level: it's not an abstract regulatory debate. It's families wondering whether their well water is safe to drink.
States Fill the Federal Gap
While federal deadlines extend and standards get reconsidered, states are moving faster than ever. According to policy trackers, nearly 100 new PFAS bills have been introduced across 17 states in the current legislative session, with another 280 bills carrying over from 2025. Colorado, Maine, and Vermont have enacted bans on PFAS in cookware, personal care products, textiles, and cleaning supplies — effective January 1, 2026.
Virginia and Illinois now require mandatory PFAS sampling in wastewater discharge permits and biosolids. Connecticut has imposed labeling requirements on firefighter protective equipment. The PFAS remediation market has swelled to an estimated $3 billion in 2026, growing at more than 10% annually.
This patchwork of state action is becoming the de facto national standard. Manufacturers are finding it cheaper to eliminate PFAS from their supply chains entirely than to manage state-by-state compliance — exactly the market dynamic that drives real change.
Enforcement Applies to Everyone
In a reminder that environmental law doesn't respect org charts, EPA proposed a $20,000 penalty in April against the Maryland Department of Public Safety and Correction Services for Clean Water Act violations at the Jessup Correctional Facility. The case involved a Municipal Separate Storm Sewer System (MS4) — not a chemical plant, not a refinery, but a state-run prison.
It's a modest penalty. But the enforcement matters because it dismantles a persistent myth: that public agencies face lower compliance risk than private industry. They don't. The same standards apply to state departments, local governments, and federal facilities. When compliance programs are built on the assumption that enforcement is unlikely, violations accumulate.
9,728 Sites and Counting
The Environmental Working Group's PFAS contamination map, updated in March 2026, now documents 9,728 contaminated sites across all 50 states, the District of Columbia, and four territories. EPA's eleventh round of public water system testing data has confirmed what independent researchers have been saying for years: PFAS contamination is not a localized problem. It is systemic.
Approximately 176 million Americans are served by water systems with detectable PFAS. The technology exists to treat it — granular activated carbon, ion exchange, and emerging destruction technologies like supercritical water oxidation can break the carbon-fluorine bonds permanently. The question has never been whether we can clean this up. It's whether we will.
What We're Watching
At EPR Foundation, we see three dynamics converging this week:
First, the federal regulatory timeline is stretching. Extended deadlines and rescinded standards don't eliminate the health risk — they just shift the burden to communities and water utilities operating under financial constraints.
Second, states are proving that enforcement and innovation can coexist. Product bans create market incentives for safer chemistry. Mandatory testing creates data that drives accountability. Neither requires waiting for Washington.
Third, legacy contamination cases like 3M's Greystone site demonstrate that the cost of inaction compounds over decades. Every year without cleanup is another year of exposure for families who didn't create the problem.
The path forward is the same one it's always been: test the water, treat what's contaminated, hold polluters accountable, and invest in chemistry that doesn't leave a permanent footprint. States are doing it. Communities are demanding it. The federal government would do well to catch up.
