The EPA reports that hazardous levels of per- and polyfluoroalkyl substances (PFAS) found in biosolids may pose significant health risks, prompting potential regulations.

**EPA Sounds Alarm on 'Forever Chemicals' in Fertilizer**
Concerns raised over PFAS in sewage sludge used as agricultural fertilizer, exceeding safety limits.
The Environmental Protection Agency (EPA) has issued a warning regarding the presence of "forever chemicals," scientifically known as per- and polyfluoroalkyl substances (PFAS), in sewage sludge utilized as fertilizer. In a recent assessment, the agency indicated that these chemicals may pose human health risks that can exceed safe levels by several orders of magnitude, although it reassured that the overall food supply is not deemed at risk.
Research indicates that sewage sludge, when applied to agricultural land, can introduce PFAS into the soil, water supply, crops, and livestock. These synthetic compounds are prevalent in everyday products such as nonstick pans and stain-resistant fabrics and have been linked to various serious health issues, including elevated cancer risks. Notably, a report by The New York Times revealed that 3M, a major manufacturer of PFAS, detected these substances in sludge samples as early as 2000.
Historically, the EPA has promoted the use of treated wastewater sludge as a low-cost fertilizer without specific regulations concerning PFAS content. However, the agency's latest draft risk assessment suggests a shift towards more stringent oversight. If adopted, this could mark the first significant attempt to regulate PFAS levels in biosolids, while the agency continues to enforce standards for certain heavy metals and pathogens.
In light of growing environmental concerns, the Biden administration has moved forward with other measures to address PFAS contamination, including setting maximum admissible levels in drinking water and categorizing two types of PFAS as hazardous substances under federal cleanup laws. The EPA has previously stated there is no safe exposure level for these compounds, signaling a robust strategy moving forward in combating PFAS pollution.
This evolving context underscores the crucial intersection between environmental policy and public health, highlighting the need for regulatory frameworks that adapt to emerging scientific findings on harmful substances in our environment.
