The Alaska Department of Transportation and Public Facilities (DOT&PF) was recently alerted to concentrations of Per- and Polyfluoroalkyl Substances (PFAS) exceeding the state action level for drinking water in several wells located at and near the King Salmon Airport. Ten wells were sampled on or near airport property. One well located on airport property tested above the action level of 70 parts per trillion (ppt) for the sum of five PFAS compounds. The other nine wells had concentrations well below the action level of 70 parts per trillion for the sum of five PFAS compounds. The Alaska Department of Environmental Conservation (DEC) began initial sampling of private water wells near airport property in December.

DOT&PF has contracted Shannon & Wilson, Inc. to finish the preliminary investigation, which includes an in-depth well search and sampling event.

PFAS are commonly used in products for fire suppression, resistance to wear, and repelling oil, stains, grease, and water. PFAS can be found in carpets, upholstery, apparel, paper, nonstick cookware, food packaging, personal care products, and in firefighting aqueous film forming foams (AFFF). The use of AFFF during firefighting equipment testing at the King Salmon Airport is the presumed source of PFAS contamination in the affected wells. PFAS are considered emerging contaminants and the health effects are not yet well characterized.
