Drinking water quality in Quillan
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at <0,029 µg/L. The EU limit is 0.1 µg/L, so this water is at 0 % of the limit. (10 April 2026)
This source does not list each PFAS substance separately, so we cannot compare this water with the health limit.
4 PFAS (see each substance)
| Acide sulfonique de perfluorobutane (PFBS) | <0,001 µg/L |
| Acide perfluorohexanoïque (PFHXA) | <0,002 µg/L |
| Acide perfluorobutanoïque (PFBA) | <0,002 µg/L |
| Acide perfluorododécanoique (PFDoDA) | <0,001 µg/L |
