PFAS in Verzenay's tap water: under 4 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
No PFAS detected
The lab sees nothing below 4 ng/L, 8 times our benchmark of 0.5 ng/L. Water above our benchmark would pass this check unnoticed.
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.
The lab detects each of the four substances from 1 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

In Verzenay, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 26 May 2026. The total is below 4 ng/L, the sum of the detection limits and 8 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,029 µg/L, below the EU legal limit (100 ng/L). 2 checks since 6 May 2025: sum of 20 PFAS up to 4 ng/L, sometimes below the detection limit.

PFAS over time in Verzenay
2 PFAS checks since 6 May 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Verzenay.
“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 |
|---|---|---|---|
| < 4 ng/L · calculated | < 29 ng/L | Verzenay | |
| < 4 ng/L · calculated | 4 ng/L | Montbré |
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 Verzenay safe to drink?
At the latest check, the water was over at least one limit. “RESULTAT D’ANALYSE NON CONFORME pour les paramètres physico-chimiques contrôlés. Teneurs en PLOMB et CUIVRE supérieures aux limites de qualité. Ces teneurs ne valent que pour le point d'utilisation où elles ont été précisément mesurées. Compte tenu de l'influence du réseau de distribution d'eau sur la dissolution des métaux, ces valeurs ne sont pas représentatives de la qualité de l'eau pour l'ensemble des consommateurs. Il sera nécessaire d'envisager le remplacement des canalisations intérieures en PLOMB. A titre préventif, s'il reste des canalisations en plomb dans le réseau de distribution, laisser couler l'eau deux minutes le matin avant de la consommer.”
How high are PFAS levels in Verzenay's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 29 ng/L. The EU limit is 100 ng/L, so this water is under 29 % of the limit. (below the EU limit)
Does the water in Verzenay also meet the strictest limits in Europe?
As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 4 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.
Are PFAS levels rising in Verzenay'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 Verzenay?
The water hardness in Verzenay is 31.6 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
