Emerging Contaminants of Concern in the Environment

Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), as well as related per and polyfluorinated alkyl substances (PFAS) are man-made chemicals that, because of their stability under extreme heat and chemical stress, as well as their surfactant properties, have been used in a variety of applications including industrial polymers (Teflon™), stain repelants (Scotch Guard™), aqueous film forming foams (AFFF or firefighting foams).

Bureau Veritas provides analyses for an extensive list of PFAS (including PFOS and PFOA), many of which are known precursor compounds, in a diverse range of environmental matrices, as well as the total oxidizable precursors (TOPs) assay.
