Growing Backlash Against Human Waste Fertilizer Over PFAS Contamination

A rising number of U.S. residents and lawmakers are opposing the use of sewage sludge (biosolids) as fertilizer, citing health and environmental risks from PFAS contamination.

• Biosolids, a byproduct of wastewater treatment plants, have been used for decades to fertilize farmland, but residents in states like Oklahoma report foul odors, fly infestations, and potential health effects.
• PFAS, or "forever chemicals", found in sludge have been linked to cancer, liver disease, and reproductive issues, yet many states do not routinely test for them.
• Lawmakers are pushing for bans or stricter regulations, while cities defend the cost savings and environmental officials acknowledge oversight gaps.

Once spread on farms, PFAS chemicals persist for generations, contaminating soil, crops, groundwater, and food chains. As scientific evidence mounts, concerns are growing over long-term risks to rural communities and the broader food supply.
