PFOS and PFOA: Investigating Emerging Contaminants of Concern

Many of the research cases that we work on involve hazardous contaminants in soil or groundwater. Increasingly, that includes research into the usage and disposal of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA).  These chemicals are part of a larger group of chemicals called polyfluoroalkyl substances (PFAS), also called perfluorocarbons (PFC).
