PFAS is just one of the emerging contaminants of concern at the moment but with the EU in 2013 setting an annual average environmental quality standard
(AA-EQS) for PFOS in surface freshwater of 0,00065 μg/l and a compliance date of 2027 there is much to be done given the difficulties currently in even achieving reliable laboratory detection at such low concentrations. This document is a good starting point for understanding more about PFAS, where it has been used, its toxicity and the European regulatory context. You can download the document here.
