Drinking water quality in Chef-Boutonne
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. (29 April 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.

Frequently asked questions
Is tap water in Chef-Boutonne safe to drink?
Yes. The latest official test (5 June 2026) checked the tap water in Chef-Boutonne and it passed every requirement.
How high are PFAS levels in Chef-Boutonne'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 Chef-Boutonne 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 Chef-Boutonne?
The water hardness in Chef-Boutonne is 27.3 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
