The Trump administration has shut down a federal rulemaking effort that would have placed strict limits on sewage sludge laced with toxic “forever chemicals” being spread across American farmland as fertilizer, discarding the EPA’s own scientific work and leaving millions of rural families and agricultural workers without federal protection from a class of chemicals linked to cancer, birth defects, and organ damage.
What the Administration Did
The EPA quietly abandoned proposed regulations targeting sewage sludge, also called biosolids, that contain PFAS — a class of roughly 16,000 synthetic compounds that do not break down in the environment or in the human body. The agency set aside its own draft health risk assessment, completed less than two years earlier, which had concluded that any PFAS concentration above one part per billion poses measurable cancer and health risks to farmers and their families.
In place of binding rules, the agency issued guidance telling Americans to research sludge companies on their own if they are concerned about toxic exposure from home fertilizers. The EPA justified stepping back by arguing that sludge is applied to only about one percent of the nation’s cropland and therefore does not constitute a widespread public threat.
Critics of that rationale note that no government agency ever systematically tracked where sludge was spread, and that most states do not test land that received applications. Without that data, the one-percent figure carries little weight as a safety assurance.
The Science Behind the Concern
PFAS chemicals have accumulated in the nation’s sewage supply for decades. A federal review conducted as far back as 2001 found PFAS present throughout the country’s sewage sludge. Regulators in Maine and Michigan found PFAS in every sample they tested. The EPA has permitted sludge to be applied to cropland since the early 1990s, primarily because it is expensive to dispose of and contains nutrients useful for plant growth.
Current EPA monitoring rules require testing biosolids for only nine heavy metals, even though the material can contain any of up to 90,000 human-made chemicals. The Biden-era draft assessment identified risks from two specific PFAS compounds — PFOA and PFOS — finding that exposure above the one part per billion threshold increases cancer risk. The vast majority of tested sludge does not fall below that level.
Research from the Southern Environmental Law Center found that more than 36 out of every 1,000 children who consumed one to two glasses daily of milk contaminated with PFOA at levels of 9.4 parts per billion could develop cancer later in life. Testing in Maine has recorded PFOA levels exceeding that threshold. For non-cancer health effects, children face risks estimated at more than 319 times higher than acceptable levels when exposed through contaminated dairy.
More than 100 farms in Maine have already been confirmed as affected by tainted sludge, including certified organic operations. Chemicals applied to land decades ago continue to contaminate the soil and nearby water sources, demonstrating the long-term consequences of inadequate early oversight. The government has not conducted meaningful testing of food grown in PFAS-contaminated fields.
Industry, Litigation, and Pushback
The waste management industry, which profits from spreading biosolids rather than disposing of them through costlier methods, has opposed regulatory action. The Public Employees for Environmental Responsibility filed suit against the EPA, alleging the agency has failed its obligations under the Clean Water Act to regulate PFAS in sludge.
Laura Dumais, an attorney with that organization, described the decision in stark terms. “It’s shocking for the EPA to take a scientific assessment and simply throw it out,” she said. “Basically, they’re saying: farmers’ lives don’t matter.”
Jean Zhuang, a senior attorney at the Southern Environmental Law Center, said the administration replaced a thorough, evidence-based review with something far less rigorous. “This administration is tossing aside a comprehensive, science-based assessment of the dangers of PFAS and replacing it with a thin, watered-down document that minimizes real harm.”
What It Means for Americans
The decision leaves agricultural workers, rural families, and consumers without a federal regulatory floor on one of the more persistent contamination problems in the American food system. Sludge has been documented migrating from application sites onto neighboring properties and into water supplies, broadening the exposure risk beyond individual farm operations.
As the administration weighs the costs of federal regulation against economic concerns — a tension that runs through many of its domestic production and industrial policy decisions — the PFAS sludge rollback raises a sharper question: when the government’s own scientists identify a measurable health hazard to American farm families, what threshold justifies federal action? The EPA’s answer, for now, appears to be that the burden falls on the public to protect itself.
