Aqueous film forming foams (AFFF) are water-based and frequently contain hydrocarbon-based surfactant such as sodium alkyl sulfate, and fluorosurfactant, such as fluorotelomers, perfluorooctanoic acid (PFOA), or perfluorooctanesulfonic acid (PFOS). Chemical compound. Perfluorooctanesulfonamide ( PFOSA) is a synthetic organofluorine compound. It is a fluorocarbon derivative and a perfluorinated compound, having an eight-carbon chain and a terminal sulfonamide functional group.

PFOA and perfluorooctanesulfonic acid (PFOS) have been estimated to be in every American person’s blood stream in the parts per billion range, though those concentrations have decreased by 70% for PFOA and 84% for PFOS between 1999 and 2014, which coincides with the end of the production and phase out of PFOA and PFOS in the US. Per- and polyfluoroalkyl substances (PFASs, also perfluorinated alkylated substances) are synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain. As such, they contain at least one perfluoroalkyl moiety, –C n F 2n –. According to OECD, there are at least 4730 different PFASs. Perfluorooctanoic acid (PFOA) (conjugate base perfluorooctanoate)—also known colloquially as C8—is a perfluorinated carboxylic acid produced and used worldwide as an industrial surfactant in chemical processes and as a material feedstock. It is a product of health concern and subject to regulatory action and voluntary industrial phase-outs. Firefighting foam is a foam used for fire suppression. Its role is to cool the fire and to coat the fuel, preventing its contact with oxygen, resulting in suppression of the combustion.

Perfluorooctane sulfonic acid (PFOS) is the most prominent of the perfluoroalkane sulfonic acids (PFSAs). PFOS has a linear perfluoroalkyl carbon chain of 8 atoms and a sulfonic acid functional group (Danish EPA, 2013). Chemical name: Perfluorooctane sulfonate Molecular formula: C8F17SO3- By 2012, PFOS and PFOA were added to the Prohibition of Certain Toxic Substances Regulations.

Substances or mixtures may not contain PFOS above 0.001% by weight (EU 757/2010). PFOS and PFOA are still used (EPA 2016b, 2016c, 2016f). Exhibit 1: Physical and Chemical Properties of PFOS and PFOA (ATSDR 2015; EFSA 2008; EPA 2016b, 2016c) Property PFOS (Free Acid) PFOA (Free Acid) Chemical Abstracts Service (CAS) number 1763-23-1 335-67-1 Physical description (physical state at room temperature and atmospheric pressure) PFOS was the predominant analyte present in the pools and all three analytes showed statistically significant increasing trends from 1972 to 2000, with concentrations reaching a plateau in the 1990s. PFOA and PFOS showed statistically significant decreasing trends during 2001-2008.
