The U.S. Environmental Protection Agency (EPA) issued a stark warning on Tuesday, highlighting the potential health risks associated with the use of treated sewage sludge as fertilizer on farms. The agency's draft risk assessment found that the presence of "forever chemicals," known as per- and polyfluoroalkyl substances (PFAS), within biosolids can pose significant health threats to both residents and consumers.

While the use of biosolids as fertilizer remains relatively limited, accounting for less than 1% of U.S. fertilized farm acres, research has consistently demonstrated the potential for PFAS contamination. These persistent chemicals have been linked to a range of serious health issues, including cancers, liver damage, and immune system impairments.

The EPA's assessment modeled potential health risks for individuals living in close proximity to sites treated with biosolids, as well as for those consuming agricultural products, such as eggs, beef, and dairy, potentially contaminated with PFAS. The findings were alarming, revealing that the risk of exposure to these harmful chemicals can, in some instances, exceed the EPA's established safety thresholds by "several orders of magnitude."

It's crucial to emphasize that the assessment does not indicate a widespread threat to the broader food supply. However, the EPA stressed that the findings necessitate immediate action. Jane Nishida, the agency's acting administrator, emphasized that the assessment will serve as a crucial guide for federal and state agencies, wastewater system operators, and farmers to implement measures aimed at preventing human exposure to these harmful chemicals.

This warning comes on the heels of the EPA's landmark decision in April to establish the first-ever national drinking water standard for PFAS, a move expected to prevent tens of thousands of deaths attributed to these pervasive contaminants. The agency is now urging all stakeholders to carefully review the draft risk assessment and provide feedback during the 60-day public comment period. This collaborative effort is crucial to minimizing the potential health risks associated with the use of biosolids as fertilizer and ensuring the safety of our food supply.

The Environmental Protection Agency (EPA) is a U.S. federal agency dedicated to safeguarding the environment and public health. Its mission encompasses enforcing environmental laws, ensuring clean air, water, and land, and cleaning up contaminated sites. The EPA also evaluates chemical safety, supports recovery planning, and works to minimize environmental threats. By developing and enforcing regulations, the EPA sets national standards that states and tribes implement. Additionally, it conducts vital research, assessments, and educational initiatives to promote environmental awareness and sustainable practices. Through these efforts, the EPA plays a critical role in protecting natural resources and ensuring a healthier future.
