In Wisconsin, where late last year Donald Trump said at a campaign stop, “I’m an environmentalist … I want clean air and clean water—really clean water,” many people want that too. Like Americans across the country, many Wisconsinites have in recent years come to understand that they have been drinking water contaminated by highly toxic “forever chemicals,” compounds known as PFAS, for decades.
This is a challenge for Trump the environmentalist, whose administration is widely expected to gut many environmental regulations and has already suspended work that would have put limits on PFAS. Yet Lee Zeldin, now the EPA’s administrator, said in his confirmation hearing last month that PFAS would be a “top priority” for the agency, and as a member of Congress, he sided with Democrats to back rules that would limit the chemicals in drinking water and make polluters pay for cleanup.
PFAS are the rare environmental issue that might evoke the bipartisan zeitgeist in which Congress passed the Clean Water Act in 1972. By then, President Richard Nixon had already overseen the creation of the EPA but vetoed the landmark water bill, which he thought was too expensive. But 17 Republicans joined with Democrats to override his veto. “If we cannot swim in our lakes and rivers, if we cannot breathe the air God has given us, what other comforts can life offer us?” Senator Howard Baker, a Republican of Tennessee, said on the October morning of the vote.
In this century, some Republicans have argued that PFAS measures are costly and come with legal burdens for businesses; the chemical industry has lobbied heavily against regulation in the U.S. and abroad. But like the environmental disasters of the 1970s, this one is alarming enough that politicians who might otherwise oppose regulation want the government to do something about it.
In his first term, Trump’s EPA issued a PFAS Action Plan to designate the compounds as hazardous, set limits, and make cleanup recommendations. But the White House also opposed a PFAS bill in Congress after the chemical industry objected to it, and the closest the administration came to fulfilling its own plans was submitting a proposal to regulate PFAS in drinking water on its very last day. In the next four years, PFAS could test whether Trump’s version of the EPA—stripped of many career employees and staffed with industry lobbyists—can do the job millions of Americans may want it to.
PFAS, as I’ve written before, are the DDT of this era, though perhaps it is more accurate to say they’re worse: Where DDT was a single compound with a single use, PFAS is an umbrella term for thousands of compounds used in a plethora of quotidian ways. They are often the reason “performance” fabrics on couches can resist stains, a rice cooker wipes clean so easily, and boots are waterproof. They make paper plates grease-resistant and conditioner extra silky. In the places where they are manufactured or are used to manufacture other things, decades of effluent have contaminated groundwater and fed into municipal water supplies. No one has figured out how to destroy the compounds, whose fluorine-carbon bond is the single most stable in organic chemistry, at scale.
And so they persist, virtually forever, cycling through the water system and accumulating in our bodies. PFAS weren’t a known concern when the Clean Water Act was created, nor were they on anyone’s radar when the Safe Drinking Water Act came into force in 1974. By the ’70s, however, 3M knew that a PFAS compound it had invented, and sold to DuPont to make Teflon, was accumulating in employees’ blood.
Now nearly every American has PFAS in theirs. Over the past half century, these compounds have been used in dozens of industries to manufacture thousands of products globally, creating a noxious waste stream that has infiltrated countless communities. Studies have linked exposure to PFAS with kidney cancer, testicular cancer, thyroid disease, decreased fertility, and developmental problems in children, among other issues.
Last year, some two decades after the EPA began investigating these compounds, the Biden administration ordered water utilities to test for several kinds of PFAS in their water, and then begin all but eliminating those compounds, for the first time. The agency says that, much like for lead, there is no safe level of two of the most common of these compounds. It also released a report warning of the dangers of spreading sewage sludge—often highly contaminated by PFAS—on fields as fertilizer, a practice that continues in many states. And it was about to set the first discharge limits for PFAS in industrial wastewater—a rule the Trump administration has now put on pause. (An EPA spokesperson told me this action was part of “common transition procedures.”) This means municipal water systems will have to test for PFAS, but manufacturers will not need to measure or limit PFAS in the wastewater they release to those systems.
In the meantime, American towns and cities are trying to deal with PFAS’s threat piecemeal. In Campbell, Wisconsin, a town on a riverine island where people watch bald eagles hunt for fish, and raise their kids in the houses where they were raised, water samples from residents’ wells first came back positive for PFAS in 2020. Firefighting foam, made of PFAS, was used to put out plane-crash fires and to train firefighters at a nearby airport for decades. Residents now wonder if that explains the many unusual diagnoses among their neighbors, Lee Donahue, a Campbell town supervisor, told me: testicular cancer in a 20-year-old, or an ovarian cancer that usually strikes later in life in a woman in her 30s.
Nearly five years after those water tests, residents are still drinking bottled water while the town board works to reroute the drinking-water supply away from contaminated wells and toward a new source. That switch is partly funded by grants from President Joe Biden’s Bipartisan Infrastructure Law, which Trump has put on pause, and partly by EPA grants secured by Senator Tammy Baldwin, a Democrat, and the town’s representative, Derrick Van Orden, a Republican. “This isn’t the most popular Republican position, I don’t really care,” Van Orden told the local ABC affiliate at the time the grant was announced. “When you turn on your faucet, it doesn’t ask if you’re a Republican or a Democrat.”
Campbell is a microcosm of a swing state: It split its vote almost exactly 50–50 between Trump and Kamala Harris, Donahue, who is also a town election worker, told me. On the other side of the state, Marinette, a city of 11,000, is an “extremely red community” that is dealing with its own PFAS problems, Cindy Boyle, a former town-board chairperson, told me. At 53, Boyle realizes she may have been drinking water tainted with PFAS her whole life: Tyco Fire Products tested its firefighting foam on land a half mile from the house where she raised her three sons, and its effluent was spread as sludge on fields within a mile of the house she grew up in, she said. The company was sued by the state, public water systems, and some residents in the area. Boyle was not one of them; still, the company is now providing a whole-house filter at her home, and distributing bottled water. (Tyco settled the suits with the water systems and residents without admitting wrongdoing; the state’s suit is on pause.)
But damage may have already been done. She had her thyroid removed in her 30s; her sister has thyroid disease now, and her mother had kidney cancer. Her husband has Parkinson’s disease; recent research shows that PFAS can accumulate in the brain and links them to neurological disorders. Boyle is registered independent from a conservative family, and she’d “take a Bush any day now,” she told me. But she says she can’t vote for anyone who isn’t interested in clamping down on PFAS.
In Wisconsin, Democrats and Republicans are currently locked in a battle at the statehouse over how to do that. Republicans have been holding up a proposed fund for testing and remediation out of fears it could force landowners to pay for cleanups of pollution they didn’t cause; on Tuesday Governor Tony Evers, a Democrat, announced a state budget meant to resolve their concerns and release the funds—if the legislature passes it.
In the absence of federal regulation, states’ efforts to address PFAS have been patchwork and politically unpredictable. In West Virginia, which voted for Trump by a ratio of 7 to 3 and is arguably the birthplace of the PFAS crisis in the U.S., former Governor Jim Justice, a Republican, passed legislation to curb it. In North Carolina, where an estimated 2.5 million residents have PFAS in their tap water, Republican appointees to a state commission have stalled rule making that would set clear limits on PFAS’s presence there. Maine, which has a Democrat-controlled legislature and a widespread PFAS crisis, has passed some of the most stringent PFAS bills in the nation. New York was among the first states to declare certain PFAS hazardous substances, but it also plans to double the volume of sludge it spreads on fields by 2050.
Tackling PFAS contamination meaningfully will require federal effort. During Trump’s previous term, he appointed a former chemical-industry executive to oversee toxic chemicals at the EPA, where she rewrote rules, making it harder to track their health impacts. Back then, Americans in some states were just beginning to understand the threats PFAS posed. Now, eight years later, the landscape is very different—and states are watching. In his time as a congressional representative from New York, Zeldin was in favor of getting rid of PFAS contamination, going so far as to urge the EPA to move faster to regulate it. At his confirmation hearing, he gave no details of how he would proceed on PFAS as EPA administrator, and when I asked the EPA for more specifics, a spokesperson pointed me to the action plan from the first term. Whatever steps Zeldin does take will show what making an issue a priority looks like for Trump’s EPA in this term, and define how far this administration’s environmentalism actually goes.
