In agricultural settings, perfluoroalkyl and polyfluoroalkyl substances (PFAS) have entered soil and water through many routes, including proximity to point sources, the application of biosolids, and irrigation with water from wastewater treatment plants. Assessing whether the implementation of conservation practices on agricultural land curtails or exacerbates PFAS contamination is complicated by knowledge gaps about the prevalence, fate, transport, and toxicity of PFAS on farms. This study will provide an initial framework to guide the efforts of the U.S. Department of Agriculture’s programs that deal with conservation on the land to respond to the impacts of PFAS contamination of agricultural land.

Per- and polyfluoroalkyl substances, known as PFAS, are widespread, persistent chemicals that can move through soils, water, crops, livestock, and food systems. Agricultural lands may receive PFAS through pathways such as organic soil amendments, irrigation water, atmospheric deposition, or off-site...
