Drinking water quality in Pont-Aven
PFAS in drinking water
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. (19 March 2026)
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.

Official assessment
The latest official test passed all quality requirements.
„Eau d’alimentation conforme aux limites de qualité mais ne satisfaisant pas totalement aux références de qualité en raison d’une conductivité inférieure à la valeur de référence minimale de 200µS/cm et d'un indice relatif à l’équilibre calco carbonique supérieur à 2. Cet indice traduit le caractère naturellement peu minéralisé de l’eau, susceptible d’interagir avec les matériaux constitutifs des canalisations, sans incidence directe sur la santé du consommateur. Eau agressive. A noter la détection d'Aminosulfonyl-N,N-Dimethylnicotin (ASDM), produ it de dégradation d'un herbicide.“

Frequently asked questions
Is tap water in Pont-Aven safe to drink?
Yes. The latest official test (2 June 2026) checked the tap water in Pont-Aven and it passed every requirement.
How high are PFAS levels in Pont-Aven's drinking water?
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. (below the EU limit)
Does the water in Pont-Aven also meet the strictest limits in Europe?
Yes. Even against Europe's strictest limit, the health limit of 0.004 µg/L used in Sweden since 2026, the measured value of 0 µg/L stays below.
How hard is the water in Pont-Aven?
The water hardness in Pont-Aven is 9.4 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
