Screening for 26 per- and polyfluoroalkyl substances (PFAS) in German drinking waters with support of residents.

ABSTRACT: The occurrence of per- and polyfluoroalkyl substances (PFAS) in water cycles poses a challenge to drinking water quality and safety. In order to counteract the large knowledge gap regarding PFAS in German drinking water, 89 drinking water samples from all over Germany were collected with the help of residents and were analyzed for 26 PFAS by high-performance liquid chromatography with tandem mass spectrometry (HPLC-MS/MS). The 20 PFAS recently regulated by sum concentration (PFAS_∑20), as well as six other PFAS, were quantified by targeted analysis. In all drinking water samples, PFAS_∑20 was below the limit of 0.1 μg/L, but the sum concentrations ranged widely from below the limit of quantification up to 80.2 ng/L. The sum concentrations (PFAS_∑4) of perfluor
