PFAS in Miré's tap water: 1.8 ng/L, 3.6x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
3.6× 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 Morannes sur Sarthe-Daumeray, on the same distribution network as Miré (MORANNES). 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 Miré, the 4 most closely watched PFAS (PFAS-4) add up to 1.8 ng/L (0.0018 µg/L) at the latest PFAS check on 11 May 2026. That's 3.6 times our 0.5 ng/L health benchmark, but below 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 Morannes sur Sarthe-Daumeray, on the same network. 3 checks since 22 January 2025: sum of 20 PFAS up to 21 ng/L, sometimes below the detection limit.

PFAS over time in Miré
3 PFAS checks since 22 January 2025, from the published measurements.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.
| Date | PFAS-4 | Sum of 20 PFAS | Sampled at |
|---|---|---|---|
| 1.8 ng/L – < 3.8 ng/L · calculated | 21 ng/L | Morannes sur Sarthe-Daumeray | |
| 0.6 ng/L – < 3.1 ng/L · calculated | 20 ng/L | Morannes sur Sarthe-Daumeray | |
| < 10 ng/L · calculated | < detection limit | Morannes sur Sarthe-Daumeray |
Calculated values: “<” is an upper bound from published thresholds, “≥” a lower bound, “–” means no published sum or complete measurement. How to read a PFAS result

Frequently asked questions
Is tap water in Miré safe to drink?
Yes. At the check on 11 May 2026, the tap water in Miré was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”
How high are PFAS levels in Miré'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 Miré 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 1.8 ng/L stays below.
Are PFAS levels rising in Miré'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 Miré?
The water hardness in Miré is 25.2 °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 Miré, so in principle the same water.
