Work is underway at Seattle-Tacoma International Airport (SEA) to be the first airport in the nation to use a special cleaning technology that more fully removes foam containing PFAS (per- and polyfluoroalkyl substances), commonly referred to as 鈥渇orever chemicals,鈥� from airport fire trucks and replace it with new fluorine-free foam. All five of SEA鈥檚 Aircraft Rescue and Firefighting (ARFF) vehicles will be ready with the new product. Prior to approvals granted in 2023, the nation鈥檚 airports were required by the Federal Aviation Administration (FAA) to continue using PFAS foams for aircraft firefighting.
PFAS substances are notoriously difficult to remediate and resistant to biodegradation. The Port of Seattle is contracting with TRS Group, Inc. for the safe and effective removal of the foam. Using TRS Group鈥檚 patented technology, concentrations of PFAS are expected to be reduced by more than 99% and generate little waste. This is TRS Group鈥檚 first cleaning at a major U.S. airport.
鈥淭he transition away from PFAS has been a top priority, met with urgency and diligence,鈥澛爏aid Port of Seattle Commission Vice President Toshiko Hasegawa.聽鈥淲e鈥檙e proud to lead as the first airport to implement this advanced level of remediation. We鈥檙e grateful to government partners that have supported us, and we are committed to supporting others preparing to transition.鈥�
