Replacing AFFF in Existing Firefighting System Components

Description:

Aqueous film forming foam (AFFF) used for airport firefighting and training exercises has historically contained per-and polyfluoroalkyl substances (PFAS and PFOS), chemicals that are persistent in the environment and have potential health impacts. If airports switch to AFFF that do not contain PFAS, there may still be contamination from residual PFASs. Research is needed to understand the extent to which PFAS can bind to existing systems (e.g., hoses, storage containers, etc.). In the event that it is found that PFASs do bind to these systems, methods for eliminating residual PFASs should also be studied. Costs associated with these methods, which could include flushing the systems or full replacement, could be an element of this research. The objective of this project should be to determine whether and to what extent PFASs bind to firefighting components after the PFAS-containing formulations are no longer in use, and if so to develop best practices and a guidebook for airports to address the contamination.
