PFAS in Mauléon's tap water: 1.7 ng/L, 3.4x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
3.4× 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.
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).
More PFAS than in 85% of the cities we track

In Mauléon, the 4 most closely watched PFAS (PFAS-4) add up to 1.7 ng/L (0.0017 µg/L) at the latest PFAS check on 13 April 2026. That's 3.4 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 8 ng/L (0.008 µg/L), below the EU legal limit (100 ng/L). 4 checks since 18 June 2025: sum of 20 PFAS up to 8.5 ng/L, sometimes below the detection limit.

Details and sources
PFAS over time in Mauléon
4 PFAS checks since 18 June 2025, from the published measurements. Samples from 4 communes on the same network: it's the same water, so each one applies to Mauléon. Samples come from 2 distribution networks. The trend refers to the network “SVL CEBRON”.
“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 | Network |
|---|---|---|---|---|
| 1.7 ng/L – < 4.7 ng/L · calculated | 8 ng/L | Mauléon | SVL LOIRE, SVL LOIRE | |
| < 4 ng/L · calculated | < detection limit | Cirières | SVL CEBRON, SVL CEBRON | |
| < 4 ng/L · calculated | 8.5 ng/L | Montravers | SVL CEBRON, SVL CEBRON | |
| 1.3 ng/L – < 4.3 ng/L · calculated | 2.5 ng/L | Bressuire | SVL CEBRON, SVL CEBRON |
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 Mauléon safe to drink?
Yes. At the check on 20 July 2026, the tap water in Mauléon 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 Mauléon's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 8 ng/L. The EU limit is 100 ng/L, so this water is at 8 % of the limit. (below the EU limit)
Does the water in Mauléon 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 1.7 ng/L stays below.
Are PFAS levels rising in Mauléon'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 Mauléon?
The water hardness in Mauléon is 16.5 °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 21 September 2026.
