PFAS in drinking water

EU legal limit

0.01 µg/L Limit: 0.1 µg/L within limit

The total of 20 PFAS ("forever chemicals") was last measured at 0.01 µg/L. The EU limit is 0.1 µg/L, so this water is at 10 % of the limit. (2 July 2025)

This source does not list each PFAS substance separately, so we cannot compare this water with the health limit.
