The U.S. Department of Agriculture is throwing its weight behind a crisis most Americans don’t know they’re living in: the contamination of farmland with PFAS, the “forever chemicals” that don’t break down in soil or water.
The new grant program offers up to $400,000 per project to fund research on PFAS sources, soil dynamics, and remediation strategies on farms. At least 13 states are now developing policies to restrict PFAS in biosolids—the wastewater sludge farmers unknowingly spread on their land—including Hawaii, Illinois, Iowa, Kansas, Maryland, Massachusetts, Mississippi, New Hampshire, New York, Oklahoma, Pennsylvania, Vermont, and Virginia.
The Invisible Invader
PFAS enters farmland through multiple pathways: biosolids used as fertilizer, contaminated irrigation water, industrial runoff, and atmospheric deposition. Once in soil, these synthetic chemicals don’t degrade. When crops take them up through their roots, PFAS ends up in the food supply—and in the bodies of the people eating it.
More than 143 million Americans are estimated to be drinking PFAS-contaminated water. The chemicals are linked to liver damage, thyroid disease, and immune suppression. For farmers, the stakes are even higher: their livelihoods depend on soil and water they can no longer trust.
A Policy Gap, Finally Closing
There is no known way to remove PFAS once it contaminates land or water. The approach, then, has to be prevention and understanding. The USDA’s research grants represent a critical acknowledgment that the agency has “sufficient opportunities” to respond to the crisis—a finding from a February 2026 report that until now went largely unheeded.
The grant program targets projects that investigate PFAS sources and pathways, soil and water dynamics, and potential remediation or management strategies. This research could reshape how biosolids are used, how contamination is detected, and what tools farmers have to protect their operations.
The Work Ahead
The problem is vast. Biosolids are applied to millions of acres annually, often in rural areas where oversight is light and farmers are simply trying to manage costs. Many don’t know their fertilizer is contaminated. Industrial sites, military bases, and airports have historically been the known PFAS hotspots, but research is revealing a much broader contamination footprint.
States are beginning to act. Illinois, for example, has banned the use of PFAS-containing sewage sludge on cropland. Others are requiring testing before application. The USDA’s research funding will help fill critical knowledge gaps: Which crops accumulate PFAS most readily? What are the long-term soil impacts? Can contaminated land ever be safely farmed again?
These questions matter to family farmers whose land is their life, whose water is their survival, and whose reputation is built on growing safe food. The USDA’s new commitment is overdue. Whether it’s sufficient is another question altogether.
What to Watch
Researchers should publish findings from these grants by late 2026 and into 2027. State biosolids policies will likely tighten further, particularly in agricultural regions. The real test will be enforcement—and funding. One round of research grants is a start. Farmers facing PFAS contamination need solutions, not just studies.
