This monitoring exercise had two objectives:
- to expand the overview of potential contamination of drinking water with perfluoroalkyl substances (PFAS) in Austria by sampling water supply facilities for which no data on PFAS is yet available
- to provide an initial overview of potential contamination of drinking water with trifluoroacetate (TFA)
A total of 331 samples from across Austria were analysed.
In two samples, a PFAS concentration slightly above the parametric value was detected. However, taking into account the minimum procedural value for PFAS, there was no clear exceedance of the parametric value (0.10 µg/l) in either sample. Consequently, there was no suspicion of a breach of food law regulations.
TFA was detected in 307 samples (corresponding to 93%) at concentrations above the limit of quantification of 0.1 µg/l. The highest concentration measured was 6.03 µg/l.
