Drinking water quality in Cléon
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0.0337 µg/L. The EU limit is 0.1 µg/L, so this water is at 34 % of the limit. (16 March 2026)
The four most harmful PFAS add up to 0.0184 µg/L. That is 4.6 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.

Frequently asked questions
Is tap water in Cléon safe to drink?
Yes. The latest official test (16 June 2026) checked the tap water in Cléon and it passed every requirement.
How high are PFAS levels in Cléon's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.0337 µg/L. The EU limit is 0.1 µg/L, so this water is at 34 % of the limit. (below the EU limit)
Does the water in Cléon also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 0.0184 µg/L. That is 4.6 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 Cléon?
The water hardness in Cléon is 23.8 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
