Scientists are investigating whether biosolid application on Pennsylvania farms represents a significant source of PFAS in soils and water. Per- and polyfluoroalkyl substances, commonly called PFAS, are a group of thousands of chemicals that are used in a wide range of industrial applications and represent a risk to human health. The application of contaminated biosolids on farm fields can result in the contamination of soils and adjacent surface waters.
