PFAS: Contaminants of Emerging Concern

PFAS, or per- and polyfluoroalkyl substances, are persistent synthetic compounds used in a variety of industrial and consumer product applications including non-stick cookware and firefighting foams. The presence of PFAS compounds in source water and drinking water is of increasing public concern due to their widespread use and environmental persistence. The resources included on this page provide information and guidance for water professionals challenged to address this emerging contaminant.

PFAS Case Studies

PFAS Case Studies, which provide details on water systems that are already responding to PFAS in drinking water. Each case study provides a background on the system and PFAS detections, details on the decision-making process, primary parameters of the treatment system design, and implementation costs. These case studies are intended to provide more background on treatment selection process.
