We advanced the science of PFAS by conducting a self-funded study of background concentrations of PFAS in surface soils. We collected and tested 100 shallow soil samples from undeveloped areas across Massachusetts. The resulting data better informs the background occurrence of PFAS in soil, helping stakeholders identify and address direct sources of PFAS contamination.
