The Trump administration just killed proposed regulations on cancer-linked 'forever chemicals' in sewage sludge spread on American farmland as fertilizer, threw out its own scientific research to justify the decision, and then advised the public to personally 'research' sludge companies to keep themselves safe. That last part is not a joke. That is the actual guidance from the Environmental Protection Agency of the United States of America.
What the Hell Is Sewage Sludge and Why Is It on Your Food
Let's start with the basics, because this story requires them. Sewage sludge, also called biosolids, is exactly what it sounds like: a byproduct of treating the waste that flows through America's sewer system. Human waste, industrial runoff, all of it processed and concentrated into a substance that is, per the Guardian, expensive to dispose of properly.
So starting in the early 1990s, the EPA found an elegant solution: spread it on cropland. It's rich in plant nutrients, the thinking went, and farmers need fertilizer, so why not connect those two dots? What nobody dwelled on was the part where American industry had spent decades dumping thousands of synthetic chemicals into the waste stream, and now those chemicals were going straight into the food supply.
PFAS are a class of roughly 16,000 compounds that do not break down in the environment or in the human body. They accumulate. Scientists and regulators link them to cancer, liver disease, kidney damage, high cholesterol, birth defects, and weakened immune systems. Regulators in Maine and Michigan found PFAS in every single sludge sample they tested. A federal review of the nation's sewage sludge found the same thing back in 2001. This is not a new discovery. It is a very old problem that powerful industries prefer to leave unaddressed.
The Science Was Right There. They Threw It Away.
In its final days, the Biden administration's EPA issued a draft health risk assessment for PFAS in sludge. The science was grim. Any level above 1 part per billion increases cancer and other serious health risks to farmers. Most sludge contains more than 1 ppb. If that threshold had been finalized and implemented, it would have effectively ended the practice of spreading contaminated sludge on food-producing land.
The Southern Environmental Law Center ran the numbers on what exposure actually looks like in practice. According to the Guardian, their calculations found that more than 36 children out of every 1,000 who drink one to two glasses of milk daily from a farm where sludge containing PFOA levels of 9.4 ppb was spread could develop cancer later in life from that milk alone. Their risk of non-cancer health problems runs more than 319 times higher than baseline. PFOA levels have exceeded 9.4 ppb in sludge tested in Maine.
The Trump EPA looked at that science, looked at those numbers, and threw them out. Not disputed them. Not commissioned new research. Threw them out and replaced them with what Jean Zhuang, a senior attorney at the Southern Environmental Law Center, described to the Guardian as a "thin, watered-down document that minimizes real harm." The EPA's new position is that sludge is only spread on about 1% of American farmland, so the risk is limited. There is one small problem with that claim: the Guardian reports that no government agency at any level has ever tracked where sludge has actually been spread.
Over 100 Maine Farms Already Contaminated, Decades Later
This is not theoretical. In Maine, more than 100 farms have already been confirmed affected by PFAS-contaminated sludge, according to the Guardian. Chemicals spread on fields decades ago are still present in the soil. They are still there on organic farms, where farmers had no idea they were growing crops in chemically saturated ground. The contamination does not stay where you put it: it migrates into surrounding properties and pollutes water sources.
Farmers have gotten sick. Their livestock have died. Their livelihoods have been destroyed. The Guardian's reporting links directly to documented cases. These are real people who trusted that the government was maintaining some baseline level of oversight over what was being applied to their land. That trust was misplaced, and the Trump administration just made sure it will stay that way.
And yet the EPA's new assessment rests on usage statistics that nobody has actually verified, covering contamination nobody is properly tracking, to protect an industry that spends real money lobbying against the regulations that would hold it accountable. The waste management industry, which profits directly from cheap sludge disposal, strongly opposes any rules that would complicate that arrangement, and has lobbied the EPA accordingly.
The Part Where the EPA Tells You to Google It
Here is where this story crosses from outrageous into something genuinely surreal. Having killed the proposed regulations, the EPA published comments in the federal register advising the American public to "research" sludge companies themselves to protect against the highly toxic chemicals in home fertilizer products widely sold for use in backyard gardens. Do your own research. Those words. From the Environmental Protection Agency.
Laura Dumais, an attorney with the Public Employees for Environmental Responsibility, called the decision "a bit bonkers" when speaking to the Guardian, which may be the most restrained description of anything in this entire story. "It's shocking that the EPA is willing to throw all of these people under the bus," Dumais said, "and the EPA's solution here is: do your own research. We're not going to regulate anything, so if you think it's dangerous then figure it out for yourself."
The agency that exists specifically to protect human health and the environment from exactly this kind of industrial contamination has concluded that its job here is done. Science assessed, science discarded, problem declared not wide enough to bother with. Go Google it, folks.
The Dingo Take
Let's be precise about what happened here. The EPA conducted scientific research. That research found that the practice of spreading PFAS-contaminated sewage sludge on farmland poses serious cancer and health risks to farmers, their families, and eventually the broader public through the food supply. The EPA then killed the proposed regulations based on that research and discarded the research itself. It replaced years of scientific work with a document that experts describe as thin and inadequate, justified by usage statistics that no government agency has ever actually verified. The waste management industry, which lobbied hard against regulation, gets to keep doing business as usual. The farmers who got sick are on their own.
This is the part where someone usually notes that environmental regulation is complicated, that cost-benefit analyses are legitimate, that industries deserve a seat at the table. Fine. But there is no version of "cost-benefit analysis" where the correct output is telling the public to personally research whether their bag of lawn fertilizer will give them cancer. That is not governance. That is an agency that has been captured so completely by the industries it regulates that it can no longer pretend to perform its basic function with a straight face.
PEER has already sued the EPA for allegedly failing to regulate PFAS in sludge under the Clean Water Act. That lawsuit will crawl through the courts while more sludge gets spread on more fields and more people eat more produce grown in chemically contaminated soil. The EPA knows this. The waste management industry knows this. And now you know it too, which is apparently all the protection this administration thinks you deserve.
