This summary describes IDA’s statistical analyses to support the validation of a measurement method for perfluoroalkyl and polyfluoroalkyl substances (PFAS), a group of synthetic chemicals that are resistant to heat, oil and water. Known as “forever chemicals” because of their rise as a persistent and mobile pollutant, PFAS were used in the aqueous film-forming foam (AFFF) the Department of Defense (DOD) developed to extinguish high-hazard liquid hydrocarbon fires. The use of AFFF resulted in the prevalence of PFAS at many military installations where DOD has environmental management responsibility, prompting interest in a validated method for measuring PFAS.
