“Forever Chemicals” Threaten U.S. Farmland: What Farmers Need to Know About PFAS

American Farmland Trust shares guidance, research, and policy solutions to help farmers navigate the growing threat of PFAS, or “forever chemicals,” contaminating U.S. farmland.

WASHINGTON, D.C. (RFD NEWS) — The contamination of agricultural land by per- and polyfluoroalkyl substances, or PFAS, is becoming a growing concern for farmers and ranchers across the country. Often referred to as “forever chemicals,” PFAS can persist in soil and water for decades.

While there is currently no scalable way to remove PFAS from soil, experts say most contaminated farms can safely return to production with the right management and support.

Farm Viability Policy Manager Emily Liss with American Farmland Trust (AFT) joined us on Wednesday’s Market Day Report to explain what PFAS are and how they intersect with agriculture.

In her interview with RFD NEWS, Liss provides background on the sources of PFAS, including industrial sources and certain soil amendments, and explains why their presence on farmland has raised alarms among producers. She also outlined the work American Farmland Trust is doing to address the issue, including policy advocacy, research, and support for farmers navigating testing, risk management, and land viability challenges related to PFAS contamination.

Finally, Liss shared ways viewers can help — from supporting science-based policy solutions to staying informed and advocating for resources that protect both farmland and farm families.
