ISO 21675 discusses water quality with a focus on the determination of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in water. ISO 21675 specifies a method for the determination of selected perfluoroalkyl and polyfluoroalkyl substances (PFAS) in nonfiltrated waters, for example, drinking water, natural water (fresh water and seawater), and wastewater containing less than 2
