Like sitting on a bomb—knowing you're working with something toxic
For decades, American fire departments trusted a foam that worked — without knowing it was quietly poisoning the people who used it and the land it touched. PFAS, the so-called 'forever chemicals' embedded in that foam, have now been linked to cancer and serious illness, particularly among firefighters who carried the highest exposures of any occupational group. More than a dozen states have begun the careful, costly work of collecting and destroying these supplies, a reckoning that arrives late but with genuine weight. This moment belongs to a longer human story about the hidden debts of industrial convenience — and who pays them first.
- Firefighters have spent decades unknowingly absorbing cancer-linked PFAS chemicals through routine use of foam that was considered the gold standard for fighting petroleum fires.
- Contaminated foam supplies still sitting in firehouses represent active exposure risks — not just to personnel, but to soil and groundwater if improperly stored or discarded.
- One firefighter described working alongside these supplies as 'like sitting on a bomb,' capturing the dread of a danger that was invisible for far too long.
- More than a dozen states have launched coordinated collection and destruction programs, working with specialized contractors because PFAS cannot simply be burned or buried.
- Fluorine-free foam alternatives are being tested and adopted, though the transition requires funding, coordination, and acceptance that the new formulas may not perform identically in every scenario.
- Removing foam from storage cannot undo decades of bodily or environmental contamination, but it halts future exposure and signals mounting regulatory pressure that will likely extend far beyond firehouses.
For more than forty years, fire departments across America relied on a foam that worked fast and worked well against petroleum fires — never questioning whether the chemicals inside it might be slowly accumulating in the bodies of the people who used it. Those chemicals, known as PFAS or 'forever chemicals,' do not break down in the environment or in the human body. Research has now linked them to cancer and serious illness, and firefighters — who handled the foam most directly — carry among the highest PFAS blood levels of any occupational group. Communities near airports and military bases, where the foam was sprayed in large quantities, have also absorbed the contamination.
More than a dozen states have responded with coordinated efforts to collect and destroy the foam supplies sitting in firehouses and storage facilities. The work is neither simple nor cheap. PFAS cannot be incinerated or buried without risk of further contamination, so states are partnering with specialized contractors and drawing on environmental remediation budgets and federal grants to do it properly. One firefighter described the experience of keeping these supplies on hand as 'like sitting on a bomb' — a phrase that captures how the knowledge of danger changes everything, even when the danger itself hasn't changed.
The transition to safer alternatives is already underway. Fire departments are adopting fluorine-free foam formulations that don't carry the same long-term health burden, even if they don't perform identically in every situation. But the cleanup effort, however necessary, is incomplete: removing foam from storage does not remove PFAS from contaminated groundwater or from the bloodstreams of those already exposed.
What this moment represents is something larger than a logistics problem. PFAS chemicals appear in non-stick cookware, food packaging, and water-resistant textiles — the firefighting foam is one of the most concentrated sources of exposure, but hardly the only one. As federal regulations on PFAS tighten and more states join the removal effort, pressure on other industries to phase out these chemicals will intensify. The foam purge is one chapter in a much longer reckoning with what we owe to the people who absorbed the costs of chemical convenience before anyone thought to ask the price.
For more than forty years, fire departments across America have relied on a single tool to fight certain kinds of fires: foam that works fast and works well. The problem is that the foam contains chemicals that don't break down in the environment or in the human body. Scientists now link these substances—known as PFAS, or "forever chemicals"—to cancer and other serious illnesses. Firefighters who handled the foam regularly, and communities near airports and military bases where it was sprayed, have absorbed these chemicals into their bloodstreams. The realization has come slowly, but it has come with force.
More than a dozen states have now launched coordinated efforts to collect, remove, and destroy the contaminated foam supplies sitting in firehouses and storage facilities across their jurisdictions. The work is methodical and necessary. Each container represents a potential exposure risk—not just to the firefighters who might use it, but to the soil and groundwater where it could leach if improperly stored or disposed of. One firefighter described the feeling of keeping these supplies on hand as "like sitting on a bomb," a phrase that captures the anxiety of knowing you're working with something dangerous every time you walk into the station.
The shift away from PFAS-containing foam marks a turning point in how fire departments approach their core mission. For decades, the foam was considered the gold standard for fighting petroleum fires and other blazes where water alone won't work. It was effective, reliable, and widely available. No one questioned whether the chemicals in it might accumulate in the body or persist in the environment indefinitely. That assumption has now been shattered by research showing the health toll.
The disposal process itself is complex. These chemicals cannot simply be incinerated or buried. States are working with specialized contractors to ensure the foam is destroyed in ways that prevent PFAS from entering the air, water, or soil. The effort requires coordination between state environmental agencies, fire departments, and waste management companies. It also requires money—funding that some states are securing through environmental remediation budgets or federal grants.
What makes this moment significant is that it reflects a broader reckoning with industrial chemicals that seemed safe when they were introduced but have proven otherwise. PFAS chemicals are used in countless products: non-stick cookware, water-resistant textiles, food packaging. The firefighting foam is just one source of exposure, but it is one of the most concentrated and direct. Firefighters have among the highest levels of PFAS in their blood of any occupational group.
The transition to safer alternatives is already underway. Fire departments are testing and adopting foam formulations that do not contain PFAS. Some use fluorine-free compounds; others rely on different chemical approaches altogether. The new foams may not perform identically to the old ones in every scenario, but they do not carry the same long-term health burden.
For the firefighters and communities affected by decades of exposure, the cleanup effort is both necessary and incomplete. Removing the foam from storage does not remove PFAS from the body or from contaminated groundwater. But it does prevent future exposure and signals that the problem is being taken seriously at the state level. As more states join the effort and as federal regulations on PFAS tighten, the pressure on other industries to phase out these chemicals will likely intensify. The firefighting foam purge is one chapter in a much longer story about how we reckon with the hidden costs of chemical convenience.

It was like sitting on a bomb— A firefighter describing the experience of working with PFAS-containing foam
The Hearth Conversation Another angle on the story
Why did fire departments use this foam for so long if it was dangerous?
Because it worked. It extinguished petroleum fires and other blazes that water couldn't touch. When it was introduced, no one understood that PFAS chemicals don't break down—they accumulate in your body and stay there. It seemed like a miracle solution.
So firefighters have been exposed to these chemicals their whole careers?
Yes. The people who handled the foam regularly, who trained with it, who used it on fires—they have some of the highest PFAS levels in their blood of any occupational group. And it's not just firefighters. Communities near airports and military bases where the foam was sprayed have contaminated groundwater.
What does it mean that more than a dozen states are collecting and destroying it now?
It means they're acknowledging the problem and trying to prevent further exposure. But it's also an admission that this stuff has been sitting in firehouses for decades. One firefighter said it felt like sitting on a bomb—knowing you're working with something toxic every day.
Can they just burn it or bury it?
No. PFAS doesn't break down that way. States are using specialized contractors to destroy it in ways that prevent the chemicals from entering the air, water, or soil. It's expensive and complicated, but it's the only way to actually eliminate the threat.
What happens to the people who were already exposed?
That's the hard part. Removing the foam doesn't remove PFAS from their bodies or from contaminated groundwater. But it stops new exposure. And it signals that the problem is finally being treated as serious.
Are fire departments switching to something safer?
They are. There are fluorine-free foams and other alternatives being tested now. They may not perform identically in every scenario, but they don't carry the same long-term health burden. It's a trade-off, but it's the right one.
