Drinking water quality in Créances
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0.001 µg/L. The EU limit is 0.1 µg/L, so this water is at 1 % of the limit. (26 November 2025)
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 authorities have not published an overall verdict for this water.
„La teneur mesurée pour le paramètre 1,4 dioxane dans le cadre d’une campagne d’analyse réalisée par l’ARS Normandie, est inférieure à la valeur guide sanitaire de 2,4 µg/l déterminée par l'ANSES dans son avis du 11 décembre 2025.“

Frequently asked questions
Is tap water in Créances safe to drink?
All the values shown here (11 June 2026) are within the legal limits, but the authorities have not published an overall verdict for this water.
How high are PFAS levels in Créances's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.001 µg/L. The EU limit is 0.1 µg/L, so this water is at 1 % of the limit. (below the EU limit)
Does the water in Créances 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 Créances?
The water hardness in Créances is 21.2 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 28 August 2026.
