PFAS in Dannes's tap water: 6 ng/L, 12x our 0.5 ng/L benchmark

Last PFAS check: · Source: Hub'eau

PFAS in drinking water

12× above our health benchmark

Amount found in the water 6 ng/L 0.006 µg/L · the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

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 Dannes, the 4 most closely watched PFAS (PFAS-4) add up to 6 ng/L (0.006 µg/L) at the latest PFAS check on 30 April 2026. That's 12 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 12 ng/L (0.012 µg/L), below the EU legal limit (100 ng/L).

Frequently asked questions

Is tap water in Dannes safe to drink?

Yes. At the check on 31 July 2026, the tap water in Dannes 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 Dannes's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 12 ng/L. The EU limit is 100 ng/L, so this water is at 12 % of the limit. (below the EU limit)

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

No. The four most harmful PFAS add up to 6 ng/L. That is 1.5 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).

How hard is the water in Dannes?

The water hardness in Dannes is 25.4 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
