In the aviation industry, PFAS-containing aqueous film-forming foams (AFFF) are used in fire responses and training. PFAS are a group of more than 12,000 man-made chemicals that can be found in a variety of products. The regulatory framework and science of PFAS are rapidly evolving, creating business and environmental risks related to AFFF storage, management and use. Emerging issues for airports include new regulatory requirements for sampling and characterization, impacts of AFFF releases to the environment and the transition from legacy to modern PFAS-containing foams to fluorine free foams. This white paper, currently featured in Airport Improvement, focuses on some unique strategies and situations we have encountered at some airport sites.
