PFAS Source Differentiation Guide for Airports

Airports face increasing regulatory and technical challenges for addressing per- and polyfluoroalkyl substances (PFAS) found on or near their facilities. Sources of PFAS may be attributable to activities such as the use of aqueous film forming foam during aircraft rescue and firefighting activities or from airport neighbors who use products that contain PFAS.

ACRP Research Report 255: PFAS Source Differentiation Guide for Airports, from TRB's Airport Cooperative Research Program, provides recommended practices for determining the source of PFAS detected in soil and water on or near an airport.

Supplemental to the report is an Excel tool that can be customized by the user to assist with PFAS source differentiation approaches.
