Drinking water quality in Châtellerault
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0.0167 µg/L. The EU limit is 0.1 µg/L, so this water is at 17 % of the limit. (17 April 2026)
The four most harmful PFAS add up to 0.004 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.

Frequently asked questions
Is tap water in Châtellerault safe to drink?
Yes. The latest official test (18 June 2026) checked the tap water in Châtellerault and it passed every requirement.
How high are PFAS levels in Châtellerault's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.0167 µg/L. The EU limit is 0.1 µg/L, so this water is at 17 % of the limit. (below the EU limit)
Does the water in Châtellerault 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 0.004 µg/L stays below.
How hard is the water in Châtellerault?
The water hardness in Châtellerault is 15 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
