PFAS in Kaysersberg Vignoble's tap water: 4 ng/L, 8x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
8× 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 Kaysersberg Vignoble, the 4 most closely watched PFAS (PFAS-4) add up to 4 ng/L (0.004 µg/L) at the latest PFAS check on 22 April 2026. That's 8 times our 0.5 ng/L health benchmark, exactly at Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 7 ng/L (0.007 µg/L), below the EU legal limit (100 ng/L). 5 checks since 22 April 2025: sum of 20 PFAS up to 12 ng/L, sometimes below the detection limit.

Details and sources
PFAS over time in Kaysersberg Vignoble
5 PFAS checks since 22 April 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Kaysersberg Vignoble. Samples come from 3 distribution networks. The trend refers to the network “SIGOLSHEIM”.
“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 Kaysersberg Vignoble safe to drink?
Yes. At the check on 28 July 2026, the tap water in Kaysersberg Vignoble was within every limit tested. Outside a reference value: Electrical conductivity 120 µS/cm on 28 July 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, agressive, très faiblement minéralisée susceptible, dans certaines conditions défavorables (notamment stagnation de l'eau), 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 canalisation en plomb dans les parties privatives des réseaux doit être vérifiée.”
How high are PFAS levels in Kaysersberg Vignoble's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 7 ng/L. The EU limit is 100 ng/L, so this water is at 7 % of the limit. (below the EU limit)
Does the water in Kaysersberg Vignoble 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 4 ng/L stays below.
Are PFAS levels rising in Kaysersberg Vignoble'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 Kaysersberg Vignoble?
The water hardness in Kaysersberg Vignoble is 11.7 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
