PFAS in Montrevault-sur-Èvre's tap water: 5.5 ng/L, 11x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
11× above our health benchmark
0.5 ng/L is our benchmark, not an official limit. Same EFSA method as Sweden, Denmark and the Netherlands, but stricter. It's a yearly average, compared here with the latest check.
Sample taken in Mauges-sur-Loire, on the same distribution network as Montrevault-sur-Èvre (MONTJEAN). The health authority samples one tap per network; a network carries the same treated water everywhere.
More about this result
The US also limits PFOA and PFOS to 4 ng/L each, per substance.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

In Montrevault-sur-Èvre, the 4 most closely watched PFAS (PFAS-4) add up to 5.5 ng/L (0.0055 µg/L) at the latest PFAS check on 17 June 2026. That's 11 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 21 ng/L (0.021 µg/L), below the EU legal limit (100 ng/L). Sampled in Mauges-sur-Loire, on the same network. 4 checks since 24 March 2025: sum of 20 PFAS up to 21 ng/L, sometimes below the detection limit.

Frequently asked questions
Is tap water in Montrevault-sur-Èvre safe to drink?
Yes. At the check on 28 July 2026, the tap water in Montrevault-sur-Èvre was within every limit tested. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité (anomalies bactériologiques sans incidence s anitaire).”
How high are PFAS levels in Montrevault-sur-Èvre's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 21 ng/L. The EU limit is 100 ng/L, so this water is at 21 % of the limit. (below the EU limit)
Does the water in Montrevault-sur-Èvre also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 5.5 ng/L. That is 1.38 times Sweden's legal limit of 4 ng/L, in force since 2026. Germany will set a similar one in 2028. The water still passes the current EU legal limit (100 ng/L for the total of 20 PFAS).
Are PFAS levels rising in Montrevault-sur-Èvre's tap water?
Calculated PFAS-4 values are listed in the table. The chart uses laboratory-published sum-of-20 results; there are too few laboratory-published PFAS-4 sums for the existing trend calculation.
How hard is the water in Montrevault-sur-Èvre?
The water hardness in Montrevault-sur-Èvre is 15.5 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
