Per- and polyfluoroalkyl substances (PFASs) are a group of thousands of chemicals that are used in a wide range of industrial applications and represent a risk to human health. They can end up on farm fields through the application of contaminated biosolids. This occurs when biosolids are sourced from a wastewater treatment facility that receives water contaminated with PFASs. Scientists are investigating whether biosolid application on Pennsylvania farms represents a significant source of PFASs in soils and water.
