In March 2019, Buchanan Field was issued an order by the State Water Resources Control Board requiring airports operating pursuant to 14 CFR Part 139 conduct a “one-time preliminary site investigation” regarding the storage and use of Per- and Polyfluoroalkyl Substances (PFAS), including soil and ground water testing. As such, the Airport will be performing testing on the airfield which is expected to begin the week of February 24
. Testing is not expected to impact aircraft operations.
PFAS is a family of more than 3,000 man-made and mostly unregulated chemicals that are resistant to degradation in the environment. PFAS are manufactured globally and have been used in the production of many industrial and household products such as dental floss, non-stick cookware and products, waterproof products, cleaning products, and fire-fighting foams.
The Federal Aviation Administration (FAA) requires Part 139 airports provide aircraft rescue and firefighting (ARFF) services using aqueous film-forming foam (AFFF) that meets military specifications (MIL-PRF-24385)(MilSpec), which include PFAS constituents. Part 139 airports have no option but to comply with FAA mandates in order to maintain their operating certificates and maintain eligibility for future federal funding opportunities.
