The ABCs of PFAS in Water Supplies
Perfluorinated alkyl substances (PFASs) are a persistent group of manufactured organofluorine chemicals which have served many purposes in industrial and consumer product applications. Also referred to as perfluorinated compounds (PFCs), PFASs have been utilised for their ability to repel oil and water and long-term stability. Several compounds are categorized as PFASs, including perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). Find out why these two compounds are the primary concern to drinking water utilities and regulators.
