Forever chemicals are very good at fighting fires.
Hindsight is 20-20, but boy have we had a lot of bad ideas.
We laid lead pipes to transport our drinking water. We let our kids play in clouds of DDT. We textured our ceilings with asbestos fibers. And until this week, nothing prevented municipalities across the country from allowing cancer-causing chemicals into the water that flows from the kitchen sinks of nearly half of Americans.
On Wednesday, the Environmental Protection Agency announced it would tolerate only exceptionally low levels of six perfluoroalkyls and polyfluoroalkyls — a group collectively known as PFAS, or “forever chemicals” — in U.S. drinking water. The chemicals, which are used for everything from waterproofing raincoats to making stain-resistant rugs, have been linked to severe health problems such as kidney, testicular, prostate, and colorectal cancers, of which diagnoses have been on the rise. An estimated 98% of us have traces of PFAS in our bodies, which often got there in the first place because of something we drank.
Environmental groups were quick to applaud the decision, calling it “overdue” and a “huge victory.” But despite being a huge step toward improving public health, the EPA’s action does not stop PFAS from entering America’s groundwater in the first place. One of the most pernicious sources is also one of the most useful: firefighting foam.
“Aqueous film forming foam,” or AFFF (“A-triple-F”), is highly effective at putting out oil and gasoline fires, which is why commercial airports, refineries, the military, and large ships keep it ready to hand. “When you take a shower, the soap and the shampoo you use spreads out the water into a foam — it suds,” David Trueba, the CEO of Revive Environmental, a company that has developed a method of breaking down PFAS that meets the EPA’s standards, told me. “AFFF does the same thing, but it prevents oxygen from getting to a grease or an oil fire. The PFAS molecules do an excellent job of creating bubbles and foam.”
The specific PFAS chemicals used in the foam are perfluorooctanesulfonic acid or perluorooctanoic acid, both newly restricted under the EPA’s drinking water guidance — but again, nothing prevents companies from continuing to manufacture them. The somewhat limited and specific uses of AFFF might make it seem like a threat mainly to firefighters and aviation professionals, rather than the general public. But in fact, the foam is one of the primary ways PFAS gets into drinking water because it is “directly applied to the environment when conducting training and responding to fires,” Shalene Thomas, the senior emerging contaminants program manager at Battelle, Revive Environmental’s parent company, told me. To add insult to injury, airports are required to test their foam annually, for safety reasons.
Even with the EPA’s new regulations, Thomas said, “until these releases are fully delineated, sources removed, and treatment installed, the risk of exposure from drinking water remains.”
Airports, municipal fire departments, and the military are all moving away from using AFFF to fight liquid fires, but that leaves an estimated 10 to 15 million gallons of the foam in the United States alone, which will have to be carefully processed to neutralize their danger, lest they end up in landfills where they might, of course, leech into the groundwater. Their persistence in the environment is a side effect of the strong bonds that make PFAS so effective — and what makes industry so reluctant to give them up — but it’s also what makes them incredibly difficult to abate. “If you’re playing Red Rover, normal molecules look like you and I — we can lock arms, and they can break through,” Trueba explained. But with PFAS, “We’re playing against The Rock and John Cena. That’s how strong the bond is.”
This conundrum has led some water utilities to complain about costs from a problem they say is not of their own making and is often prohibitively expensive to address. Large water utilities that serve populations of more than 10,000 people may only have a budget of $10 million for everything they do. “Having a $3 to $5 million bogey put on top of that” to treat water for PFAS, as directed by the EPA — “that’s where the comments usually come from,” Trueba said. While the Biden administration allotted an additional $1 billion in its drinking water plan on top of the nearly $4 billion set aside to address PFAS and other contaminants in the Bipartisan Infrastructure Law, $5 billion is still “going to go not very far,” Trueba said. For example, Washington state’s public water utilities alone have said they’d need $1.6 billion for their initial PFAS cleanup.
John Rumpler, the clean water director at Environment America, is less tolerant of complaints from utilities. “For the public water utilities to be sitting there playing the victim and saying, ‘Oh my gosh, the EPA is imposing all these terrible costs on us’ — what do we tell our kids? Do something to help yourself,” he told me. “The part of the problem that utilities can clearly control is to shut off the tap on those industrial wastewater sources that are sending their PFAS to you.” State officials can also set pretreatment standards for industrial dischargers so PFAS are removed before they ever end up in waste sewage plants.
So far, this is how action against AFFF has come about — from individual state lawsuits and takeback programs. Back in 2018, the city of Stewart, Florida, sued chemical manufacturer 3M over the firefighting foam that had contaminated its water table, a suit that was eventually joined by 4,000 cities around the country. The eventual settlement totaled more than $10 billion and sparked the race to create technologies like Revive’s PFAS Annihilator, which uses intense heat and pressure to break the molecule’s stubborn chemical bonds. Other users of AFFF started to look closer at the foam, too; the Pentagon plans to phase out its use this year after an investigation by the Defense Department, and a spokeswoman for the National Fire Protection Association pointed me toward the organization’s ongoing workshops aimed at mitigating health risks to its members from fire-suppressing foams.
If these efforts keep up, it’s possible that in the future PFAS will become another bad idea we disbelievingly shake our heads at when we remember how things used to be. “Our parents and our grandparents seem to have pans and rugs from before these chemicals, so I’m pretty sure that we can do without them,” Rumpler pointed out.
But until chemical manufacturers stop making substances like AFFF, the EPA has only really given the faucet one good turn toward the off position. It still continues to drip.

Did a battery plant disaster in California spark a PR crisis on the East Coast?
Battery fire fears are fomenting a storage backlash in New York City – and it risks turning into fresh PR hell for the industry.
Aggrieved neighbors, anti-BESS activists, and Republican politicians are galvanizing more opposition to battery storage in pockets of the five boroughs where development is actually happening, capturing rapt attention from other residents as well as members of the media. In Staten Island, a petition against a NineDot Energy battery project has received more than 1,300 signatures in a little over two months. Two weeks ago, advocates – backed by representatives of local politicians including Rep. Nicole Mallitokis – swarmed a public meeting on the project, getting a local community board to vote unanimously against the project.
According to Heatmap Pro’s proprietary modeling of local opinion around battery storage, there are likely twice as many strong opponents than strong supporters in the area:

Yesterday, leaders in the Queens community of Hempstead enacted a year-long ban on BESS for at least a year after GOP Rep. Anthony D’Esposito, other local politicians, and a slew of aggrieved residents testified in favor of a moratorium. The day before, officials in the Long Island town of Southampton said at a public meeting they were ready to extend their battery storage ban until they enshrined a more restrictive development code – even as many energy companies testified against doing so, including NineDot and solar plus storage developer Key Capture Energy. Yonkers also recently extended its own battery moratorium.
This flurry of activity follows the Moss Landing battery plant fire in California, a rather exceptional event caused by tech that was extremely old and a battery chemistry that is no longer popular in the sector. But opponents of battery storage don’t care – they’re telling their friends to stop the community from becoming the next Moss Landing. The longer this goes on without a fulsome, strident response from the industry, the more communities may rally against them. Making matters even worse, as I explained in The Fight earlier this year, we’re seeing battery fire concerns impact solar projects too.
“This is a huge problem for solar. If [fires] start regularly happening, communities are going to say hey, you can’t put that there,” Derek Chase, CEO of battery fire smoke detection tech company OnSight Technologies, told me at Intersolar this week. “It’s going to be really detrimental.”
I’ve long worried New York City in particular may be a powder keg for the battery storage sector given its omnipresence as a popular media environment. If it happens in New York, the rest of the world learns about it.
I feel like the power of the New York media environment is not lost on Staten Island borough president Vito Fossella, a de facto leader of the anti-BESS movement in the boroughs. Last fall I interviewed Fossella, whose rhetorical strategy often leans on painting Staten Island as an overburdened community. (At least 13 battery storage projects have been in the works in Staten Island according to recent reporting. Fossella claims that is far more than any amount proposed elsewhere in the city.) He often points to battery blazes that happen elsewhere in the country, as well as fears about lithium-ion scooters that have caught fire. His goal is to enact very large setback distance requirements for battery storage, at a minimum.
“You can still put them throughout the city but you can’t put them next to people’s homes – what happens if one of these goes on fire next to a gas station,” he told me at the time, chalking the wider city government’s reluctance to capitulate on batteries to a “political problem.”
Well, I’m going to hold my breath for the real political problem in waiting – the inevitable backlash that happens when Mallitokis, D’Esposito, and others take this fight to Congress and the national stage. I bet that’s probably why American Clean Power just sent me a notice for a press briefing on battery safety next week …
And more of the week’s top conflicts around renewable energy.
1. Queen Anne’s County, Maryland – They really don’t want you to sign a solar lease out in the rural parts of this otherwise very pro-renewables state.
2. Logan County, Ohio – Staff for the Ohio Power Siting Board have recommended it reject Open Road Renewables’ Grange Solar agrivoltaics project.
3. Bandera County, Texas – On a slightly brighter note for solar, it appears that Pine Gate Renewables’ Rio Lago solar project might just be safe from county restrictions.
Here’s what else we’re watching…
In Illinois, Armoracia Solar is struggling to get necessary permits from Madison County.
In Kentucky, the mayor of Lexington is getting into a public spat with East Kentucky Power Cooperative over solar.
In Michigan, Livingston County is now backing the legal challenge to Michigan’s state permitting primacy law.
On the week’s top news around renewable energy policy.
1. IRA funding freeze update – Money is starting to get out the door, finally: the EPA unfroze most of its climate grant funding it had paused after Trump entered office.
2. Scalpel vs. sledgehammer – House Speaker Mike Johnson signaled Republicans in Congress may take a broader approach to repealing the Inflation Reduction Act than previously expected in tax talks.
3. Endangerment in danger – The EPA is reportedly urging the White House to back reversing its 2009 “endangerment” finding on air pollutants and climate change, a linchpin in the agency’s overall CO2 and climate regulatory scheme.
