Region: Auvergne-Rhône-Alpes Population: 19,445 Water supplier: SEMIDAO Latest sample: 24 June 2026
Passes the EU legal limit and below the health limit

PFAS in drinking water

EU legal limit
<0,029 µg/L Limit: 0.1 µg/L within limit

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. (16 July 2025)

Health limit (used in Sweden)
0 µg/L the 4 most harmful PFAS (PFAS-4) · Limit: 0.004 µg/L below health limit

The four most harmful PFAS add up to 0 µg/L, below the health limit of 0.004 µg/L used in Sweden since 2026.

Substances too small to measure count as 0, so the real total may be higher.

5 PFAS (see each substance)
Acide perfluorodecane sulfonique (PFDS) <0,001 µg/L
Acide perfluoropentanoïque (PFPEA) <0,001 µg/L
Acide perfluoropentane sulfonique (PFPS) <0,001 µg/L
Acide perfluoro tridecane sulfonique (PFTrDS) <0,005 µg/L
Perfluorohexane sulfonate (PFHXS) <0,001 µg/L
