How Airports Can Approach PFAS Contamination Concerns

Per- and polyfluoroalkyl substances, or PFAS, have become a growing concern for airports as their human health impacts have become clearer. These "forever chemicals" have a wide variety of applications including a number of uses with particular significance for airports, but they are increasingly being targeted by environmental regulations seeking to sharply reduce or eliminate their use.

In the latest from HDR's Experts Talk interview series, Senior Aviation Program Manager Marc Gambrill, a former chief development officer at a commercial airport, discussed the challenges that PFAS pose for airports, along with Kate Garufi, HDR's site investigation and remediation practice leader. The two explained why airports are a particular focus of PFAS cleanup, the current status of regulations and how airports should be responding now to this environmental challenge.

"As PFAS contamination becomes more high profile, contractors - and the public - are raising concerns about the possibility of dealing with the contamination during construction projects," Gambrill said. "We've been a part of multiple projects recently in which contractors specifically asked about materials management, especially if PFAS is found in excavated soil."

The two offer context on the current regulatory situation as well as strategies that airports can explore as this environmental challenge continues.

"Keep PFAS on your airport's radar - continue to review and revisit your strategy," Garufi advised. "This will ensure your airport understands regulations, their impacts, and is prepared to take assessment or cleanup actions, if required."

HDR's Experts Talk interview series shines a light on various aspects of transportation infrastructure design and delivery. Each subject matter expert offers unique expertise and insights about new and ongoing trends, emerging technologies and the human side of infrastructure.
