Development of Forensic Guidelines and Tools for PFAS Source Differentiation at Airports

Airports across the United States face increasing regulatory and technical challenges for addressing per- and polyfluoroalkyl substance (PFAS) releases into groundwater and surface water from the use of aqueous film forming foams (AFFF) in aircraft rescue and firefighting (ARFF) activities. In many cases, airports also have tenants who store and use AFFF. Additionally, airports located in industrial areas may have neighbors who use and/or store AFFF or other PFASs. Construction activities at or near the airport can lead to the discovery of PFAS-impacted soils, and there is little understanding of how to determine the source of the contamination. Distinguishing among PFAS sources is an important aspect of any site characterization program and is useful for managing the cost and liability of remediation. Research is needed to advance the understanding of source differentiation so it can be applied to airports with greater confidence. The objective of this research is to develop a forensic method for differentiating among multiple potential sources of PFAS contamination at an airport and its environs.
