PFAS in Vassonville's tap water: 5.6 ng/L, 11.2x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
11.2× 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 Tôtes, on the same distribution network as Vassonville (AUFFAY-TOTES). 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 Vassonville, the 4 most closely watched PFAS (PFAS-4) add up to 5.6 ng/L (0.0056 µg/L) at the latest PFAS check on 22 July 2026. That's 11.2 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 10.8 ng/L (0.0108 µg/L), below the EU legal limit (100 ng/L). Sampled in Tôtes, on the same network. 3 checks since 4 February 2025: sum of 20 PFAS from 4 ng/L to 14.2 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).
Details and sources
PFAS over time in Vassonville
3 PFAS checks since 4 February 2025, from the published measurements. Samples from 3 communes on the same network: it's the same water, so each one applies to Vassonville.
“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 |
|---|---|---|---|
| 5.6 ng/L – < 6.6 ng/L · calculated | 10.8 ng/L | Tôtes | |
| 8.5 ng/L – < 9.5 ng/L · calculated | 14.2 ng/L | Saint-Victor-l'Abbaye | |
| < 5 ng/L · calculated | 4 ng/L | Fresnay-le-Long |
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 Vassonville safe to drink?
Yes. At the check on 22 July 2026, the tap water in Vassonville 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 Vassonville's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 10.8 ng/L. The EU limit is 100 ng/L, so this water is at 11 % of the limit. (below the EU limit)
Does the water in Vassonville also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 5.6 ng/L. That is 1.4 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 Vassonville'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 Vassonville?
No hardness value is available for Vassonville in this source.
