Drinking water quality in Chanceaux-sur-Choisille
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0.02 µg/L. The EU limit is 0.1 µg/L, so this water is at 20 % of the limit. (25 June 2026)
The four most harmful PFAS add up to 0.0065 µg/L. That is 1.6 times the health limit of 0.004 µg/L that Sweden made law in 2026. Germany will set a similar limit in 2028.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).
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 et non conforme aux références de qualité pour la température. Une température élevée de l’eau stimule la croissance des micro-organismes et peut accroître les problèmes liés au goût, à l’odeur, à la coloration et à la corrosion. La valeur des micro-organismes revivifiables à 22°C est anormalement élevée. Le dénombrement de micro-organismes revivifiables ne doit pas présenter de variations anormales. Un nouveau contrôle a été effectué le 01/07/2026 pour analyser les paramètres bactériologiques en application de l'article R.1321-17 du Code de la Santé PubliquE.“

Frequently asked questions
Is tap water in Chanceaux-sur-Choisille safe to drink?
Yes. The latest official test (25 June 2026) checked the tap water in Chanceaux-sur-Choisille and it passed every requirement.
How high are PFAS levels in Chanceaux-sur-Choisille's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.02 µg/L. The EU limit is 0.1 µg/L, so this water is at 20 % of the limit. (below the EU limit)
Does the water in Chanceaux-sur-Choisille also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 0.0065 µg/L. That is 1.6 times the health limit of 0.004 µg/L that Sweden made law in 2026. The water still passes the current EU limit (0.1 µg/L for the total of 20 PFAS).
How hard is the water in Chanceaux-sur-Choisille?
The water hardness in Chanceaux-sur-Choisille is 13.2 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
