Drinking water quality in Louvigné-du-Désert

Region: Bretagne Population: 3,346 Water supplier: STGS Latest sample: 12 May 2026
Passes the EU legal limit and below the health limit

PFAS in drinking water

EU legal limit
<SEUIL µg/L Limit: 0.1 µg/L within limit

The total of 20 PFAS ("forever chemicals") was last measured at <SEUIL µg/L. The EU limit is 0.1 µg/L, so this water is at 0 % of the limit. (6 May 2026)

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.
