PFAS in Villers-le-Château's tap water: 2 ng/L, 4x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
4× 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 Villers-le-Château, the 4 most closely watched PFAS (PFAS-4) add up to 2 ng/L (0.002 µg/L) at the latest PFAS check on 20 June 2025. That's 4 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 34 ng/L (0.034 µg/L), below the EU legal limit (100 ng/L).

Frequently asked questions
Is tap water in Villers-le-Château safe to drink?
At the latest check, the water was over at least one limit. “L'eau distribuée présente des concentrations en pesticides supérieures aux exigences réglementaires fixées à 0,1 µg/l, mais inférieures aux valeurs définies pour en limiter les usages sanitaires. Un contrôle renforcé est en place et des actions sont demandées à l’exploitant pour restaurer la qualité de l’eau. Cette eau est de bonne qualité pour les autres paramètres. Elle peut être consommée par tous. Néanmoins, des bactéries revivifiables à un taux élevé par rapport aux valeurs habituelles ont été détectées. Ces germes ne sont pas préjudiciables à la santé publique mais révèlent la nécessité de vérifier les installations de production, de traitement et de distribution de l'eau. L'EAU ET LES INSTALLATIONS SONT A SURVEILLER. Maintenir un résiduel en chlore de 0,3 mg/l sur l'ensemble du réseau.”
How high are PFAS levels in Villers-le-Château's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 34 ng/L. The EU limit is 100 ng/L, so this water is at 34 % of the limit. (below the EU limit)
Does the water in Villers-le-Château 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 2 ng/L stays below.
How hard is the water in Villers-le-Château?
The water hardness in Villers-le-Château is 22.2 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
