Drinking water quality in Biganos
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0 µg/L. The EU limit is 0.1 µg/L, so this water is at 0 % of the limit. (18 June 2025)
This source does not list each PFAS substance separately, so we cannot compare this water with the health limit.
