Amount found in the water 0.8 ng/L 0.0008 µg/L · the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

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 Château-Gontier-sur-Mayenne, on the same distribution network as Peuton (CC PAYS CHATEAU-GONTIER OUEST). 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.

Substances below the detection limit count as 0, so the real total may be higher.

One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

In Peuton, the 4 most closely watched PFAS (PFAS-4) add up to 0.8 ng/L (0.0008 µg/L) at the latest PFAS check on 23 April 2026. That's 1.6 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 4.3 ng/L (0.0043 µg/L), below the EU legal limit (100 ng/L). Sampled in Château-Gontier-sur-Mayenne, on the same network. 3 checks since 28 January 2025: sum of 20 PFAS up to 6.5 ng/L, sometimes below the detection limit.

Frequently asked questions

Is tap water in Peuton safe to drink?

At the latest check, the water was over at least one limit. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”

How high are PFAS levels in Peuton's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 4.3 ng/L. The EU limit is 100 ng/L, so this water is at 4 % of the limit. (below the EU limit)

Does the water in Peuton also meet the strictest limits in Europe?

Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 0.8 ng/L stays below.

Are PFAS levels rising in Peuton'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 Peuton?

The water hardness in Peuton is 17.4 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?

All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 12 September 2026.

Same water network

Same distribution network as Peuton, so in principle the same water.
