Drinking water quality in Blénod-lès-Pont-à-Mousson
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0.043 µg/L. The EU limit is 0.1 µg/L, so this water is at 43 % of the limit. (19 January 2026)
The four most harmful PFAS add up to 0.025 µg/L. That is 6.3 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 Blénod-lès-Pont-à-Mousson safe to drink?
Yes. The latest official test (24 June 2026) checked the tap water in Blénod-lès-Pont-à-Mousson and it passed every requirement.
How high are PFAS levels in Blénod-lès-Pont-à-Mousson's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.043 µg/L. The EU limit is 0.1 µg/L, so this water is at 43 % of the limit. (below the EU limit)
Does the water in Blénod-lès-Pont-à-Mousson also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 0.025 µg/L. That is 6.3 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 Blénod-lès-Pont-à-Mousson?
The water hardness in Blénod-lès-Pont-à-Mousson is 31.3 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
