PFAS in Valsonne's tap water: 32 ng/L, 64x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
64× 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 Dième, on the same distribution network as Valsonne (REGION DE TARARE PRINCIPALE). 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.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

Frequently asked questions
Is tap water in Valsonne safe to drink?
Yes. At the check on 19 May 2026, the tap water in Valsonne 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 Valsonne's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 61 ng/L. The EU limit is 100 ng/L, so this water is at 61 % of the limit. (below the EU limit)
Does the water in Valsonne also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 32 ng/L. That is 8 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 Valsonne?
The water hardness in Valsonne is 11.9 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
