PFAS in Vignot's tap water: 22 ng/L, 44x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
44× 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 Vignot, the 4 most closely watched PFAS (PFAS-4) add up to 22 ng/L (0.022 µg/L) at the latest PFAS check on 30 July 2026. That's 44 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 27 ng/L (0.027 µg/L), below the EU legal limit (100 ng/L). 2 checks since 13 March 2025: sum of 20 PFAS from 11 ng/L to 27 ng/L.

PFAS over time in Vignot
2 PFAS checks since 13 March 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 |
|---|---|---|
| 22 ng/L – < 24 ng/L · calculated | 27 ng/L | |
| 8 ng/L – < 12 ng/L · calculated | 11 ng/L |
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 Vignot safe to drink?
Yes. At the check on 30 July 2026, the tap water in Vignot was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés. Il est à noter la présence d'Anthraquinone à une teneur de 0,69 µg/L. La présence de cette substance peut avoir pour origine une réaction entre le chlore et des matériaux à base de goudron constitutifs du revêtement intérieur de réservoir et/ou de certaines canalisations en fonte. Par conséquent, une analyse complémentaire sera réalisée afin de rechercher la présence d'hydrocarbures aromatiques polycycliques (HAP), et, le cas échéant, d'en évaluer la toxicité. Le responsable de la distribution de l'eau a été informé de cette situation et invité à prendre des mesures correctives par messagerie le 12/08.”
How high are PFAS levels in Vignot's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 27 ng/L. The EU limit is 100 ng/L, so this water is at 27 % of the limit. (below the EU limit)
Does the water in Vignot also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 22 ng/L. That is 5.5 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 Vignot'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 Vignot?
The water hardness in Vignot is 29.2 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
