PFAS in Lapoutroie's tap water: 3 ng/L, 6x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
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.
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 Lapoutroie, the 4 most closely watched PFAS (PFAS-4) add up to 3 ng/L (0.003 µg/L) at the latest PFAS check on 18 May 2026. That's 6 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 3 ng/L (0.003 µg/L), below the EU legal limit (100 ng/L). 6 checks since 8 April 2025: sum of 20 PFAS up to 3 ng/L, sometimes below the detection limit.

Details and sources
PFAS over time in Lapoutroie
6 PFAS checks since 8 April 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Lapoutroie. Samples come from 4 distribution networks. The trend refers to the network “LAPOUTROIE HACHIMETTE (BAA)”.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions
Is tap water in Lapoutroie safe to drink?
Yes. At the check on 15 June 2026, the tap water in Lapoutroie was within every limit tested. Outside a reference value: pH 6.4 unité pH on 15 June 2026 (reference 6.5–9 unité pH), Electrical conductivity 57 µS/cm on 15 June 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité. Eau douce, très peu minéralisée, à pH acide, agressive, susceptible, dans certaines conditions défavorables (stagnation de l'eau notamment), de dissoudre certains métaux des canalisations. Il est conseillé de ne consommer l'eau du robinet qu'après un écoulement de 15 à 30 secondes. L'absence de canalisations en plomb dans les parties privatives des réseaux doit être vérifiée.”
How high are PFAS levels in Lapoutroie's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 3 ng/L. The EU limit is 100 ng/L, so this water is at 3 % of the limit. (below the EU limit)
Does the water in Lapoutroie 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 3 ng/L stays below.
Are PFAS levels rising in Lapoutroie'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 Lapoutroie?
The water hardness in Lapoutroie is 1.9 °f (soft). 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.
