The federal PFAS money that helped water systems start treatment builds ran out Sept. 30. A bipartisan House bill introduced Oct. 22 would replace it with $10 billion over five years, and for the contractors and engineers building treatment plants, the size of that number matters less than the word in front of it: authorize.
Reps. Laura Gillen, D-N.Y., and Brian Fitzpatrick, R-Pa., rolled out the Protect Clean Water Act at a press conference with Long Island mayors in Rockville Centre, N.Y., according to Smart Cities Dive. It’s pitched as the follow-on to the emerging-contaminants funding in the 2021 Infrastructure Investment and Jobs Act.
What the PFAS funding bill would do
The bill amends the Safe Drinking Water Act to swap the $100 million a year authorized for PFAS removal from 2020 through 2024 for $1 billion a year from 2027 through 2031. It also authorizes another $1 billion a year through the Clean Water and Drinking Water State Revolving Funds for treatment technology and water infrastructure upgrades. That’s $2 billion a year, or $10 billion over the five years, according to Gillen’s office.
Authorization isn’t appropriation, though. The bill sets a ceiling Congress may fund later, and it doesn’t put a dollar into a state revolving fund by itself. Even if it passes, the money depends on annual appropriations fights that have cut SRF budgets before.
The PFAS treatment gap is much bigger than $10 billion
The need dwarfs the bill. The American Water Works Association estimated in 2024 that more than 7,000 entry points would need capital improvements to treat PFAS, at $37.1 billion to $48.3 billion through 2029. Add operations and maintenance and AWWA puts the annualized cost at $2.7 billion to $3.5 billion.
The pressure comes from EPA’s 2024 drinking water limits of 4 parts per trillion each for PFOA and PFOS. More than 1,700 public water systems have recorded at least one result at or above that level, Smart Cities Dive reported, and many cities say they’re struggling to hit the compliance dates. That’s showing up in water rates, which is exactly the argument Gillen made in Rockville Centre.
What water contractors should watch
For the firms building granular activated carbon and ion exchange plants, the bill is a signal, not a backlog. PFAS work hasn’t depended on federal grants alone. Polluter settlements like North Carolina’s $455 million Fayetteville Works deal and ordinary utility borrowing are other sources, and large utilities keep building new plants like Fort Lauderdale’s Prospect Lake Clean Water Center.
Smaller systems are another story. They’re the ones that leaned on the IIJA money, and they’re the ones whose projects stall first if Congress lets the gap sit. Bipartisan sponsors help. A vote would help more.
