PFAS in the tap water of Vrigny (Marne): 7 ng/L, 14x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
14× 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 Gueux, on the same distribution network as Vrigny (CUGR REGION DE GUEUX). 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 Vrigny, the 4 most closely watched PFAS (PFAS-4) add up to 7 ng/L (0.007 µg/L) at the latest PFAS check on 13 January 2026. That's 14 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 9 ng/L (0.009 µg/L), below the EU legal limit (100 ng/L). Sampled in Gueux, on the same network. 2 checks since 16 June 2025: sum of 20 PFAS from 9 ng/L to 23 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).
Details and sources
PFAS over time in Vrigny
2 PFAS checks since 16 June 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Vrigny.
“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 |
|---|---|---|---|
| 7 ng/L – < 9 ng/L · calculated | 9 ng/L | Gueux | |
| 15 ng/L – < 16 ng/L · calculated | 23 ng/L | Courcelles-Sapicourt |
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 Vrigny safe to drink?
All the values shown here (2 June 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “L'eau distribuée présente des concentrations en pesticides supérieures aux exigences réglementaires fixées à 0,1 µg/l, mais inférieures aux valeurs définies pour en limiter les usages sanitaires. Un contrôle renforcé est en place et des actions sont engagées par l’exploitant pour restaurer la qualité de l’eau. Cette eau est de bonne qualité pour les autres paramètres. Elle peut être consommée par tous.”
How high are PFAS levels in Vrigny's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 9 ng/L. The EU limit is 100 ng/L, so this water is at 9 % of the limit. (below the EU limit)
Does the water in Vrigny also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 7 ng/L. That is 1.75 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 Vrigny'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 Vrigny?
The water hardness in Vrigny is 35.6 °f (hard). 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.
