Drinking water quality in Auxonne
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0.0033 µg/L. The EU limit is 0.1 µg/L, so this water is at 3 % of the limit. (21 October 2025)
The four most harmful PFAS add up to 0.0033 µg/L, below the health limit of 0.004 µg/L used in Sweden since 2026.
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.

Does the water in Auxonne 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 0.0033 µg/L stays below.
How hard is the water in Auxonne?
The water hardness in Auxonne is 20.9 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
