PFAS in drinking water

No PFAS detected

Amount found in the water < 17 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, none found
Our health benchmark 0.5 ng/L

The lab sees nothing below 17 ng/L, 34 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 2 to 5 ng/L upward. None reached that limit, so their total is below 17 ng/L rather than zero.

In Vignec, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 12 February 2026. The total is below 17 ng/L, the sum of the detection limits and 34 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,1 µg/L, below the EU legal limit (100 ng/L).

Values to watch

These results are close to their legal limit, or over it.

Outside a reference value: Electrical conductivity 157 µS/cm on 9 June 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits.

Frequently asked questions

Is tap water in Vignec safe to drink?

At the latest check, the water was over at least one limit. “Eau d'alimentation non conforme aux exigences de qualité en vigueur. C ette non-conformité concernant l'arsenic a nécessité une restriction d e la consommation de l'eau. Il a été demandé à l'exploitant d'avertir la population concernée et de prendre les mesures correctives nécessai res pour rétablir la qualité de l'eau. Un contrôle renforcé a été mis en place afin de suivre l'évolution de ce paramètre.”

How high are PFAS levels in Vignec's drinking water?

At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 100 ng/L. The EU limit is 100 ng/L, so this water is under 100 % of the limit. (below the EU limit)

Does the water in Vignec also meet the strictest limits in Europe?

The check cannot say. None of the four compounds was quantified, but the laboratory's detection limits add up to 17 ng/L, above Sweden's legal limit of 4 ng/L in force since 2026, so a value between the two would go unnoticed.

How hard is the water in Vignec?

The water hardness in Vignec is 7.7 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
