PFAS in Biosolids: A Southern Arizona Case Study

Rationale for Study

PFAS are fluorinated compounds that comprise a family of anthropogenic chemicals used for decades to make products resistant to heat, oil stains, grease, and water. Of these, perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) have been the most prominently used in the U.S. PFAS are now regarded by EPA to be “emerging contaminants”.
