PFAS: Issues and Solutions for Airports

Show Contributors: Steve Pelham, Bob Cipolletti, Bill Disguiseppi, Paul Thies


Over the past several years, there has been a surge in regulatory interest to address the public health and environmental risks from releases of per- and polyfluoroalkyl substances (PFAS), including use of aqueous film-forming foams (AFFF) for firefighting or training. This call to action has resulted in rapid development of regulations and guidance, at both the federal and state level, which are impacting the airport community. In this episode of If/When, our guests are Jacobs’ Vice President of Aviation for the Americas, Steve Pelham; Principal Hydrogeologist, Jacobs’ Aviation Environmental Lead, Bob Cipolletti; and Principal Hydrogeologist, Jacobs PFAS Global Technology Leader, Bill Diguiseppi.
