Drinking water quality in Montreuil-Bellay
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0.016 µg/L. The EU limit is 0.1 µg/L, so this water is at 16 % of the limit. (21 May 2026)
The four most harmful PFAS add up to 0.0068 µg/L. That is 1.7 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 Montreuil-Bellay safe to drink?
All the values shown here (17 June 2026) are within the legal limits, but the authorities have not published an overall verdict for this water.
How high are PFAS levels in Montreuil-Bellay's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.016 µg/L. The EU limit is 0.1 µg/L, so this water is at 16 % of the limit. (below the EU limit)
Does the water in Montreuil-Bellay also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 0.0068 µg/L. That is 1.7 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 Montreuil-Bellay?
The water hardness in Montreuil-Bellay is 23.7 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
