PFAS in Saint-Vit's tap water: 17 ng/L, 34x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
34× 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 Saint-Vit, the 4 most closely watched PFAS (PFAS-4) add up to 17 ng/L (0.017 µg/L) at the latest PFAS check on 2 February 2026. That's 34 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 28 ng/L (0.028 µg/L), below the EU legal limit (100 ng/L). 10 checks since 9 October 2023: sum of 20 PFAS up to 39.7 ng/L, sometimes below the detection limit.

PFAS over time in Saint-Vit
10 PFAS checks since 9 October 2023, from the published measurements. Samples come from 2 distribution networks. The trend refers to the network “GBM SAINT VIT”.
“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 Saint-Vit safe to drink?
Yes. At the check on 20 July 2026, the tap water in Saint-Vit was within every limit tested. “EAU CONFORME (code de la santé publique) L'eau prélevée respecte les exigences de qualité réglementaires des eaux destinées à l'alimentation humaine pour les paramètres analysés.”
How high are PFAS levels in Saint-Vit's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 28 ng/L. The EU limit is 100 ng/L, so this water is at 28 % of the limit. (below the EU limit)
Does the water in Saint-Vit also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 17 ng/L. That is 4.3 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 Saint-Vit'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 Saint-Vit?
The water hardness in Saint-Vit is 25.9 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
