PFAS in Fourg's tap water: 14 ng/L, 28x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
28× 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 Abbans-Dessus, on the same distribution network as Fourg (SDJ RESEAU PUITS D'ABBANS). 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.
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 Fourg, the 4 most closely watched PFAS (PFAS-4) add up to 14 ng/L (0.014 µg/L) at the latest PFAS check on 14 April 2025. That's 28 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 15 ng/L (0.015 µg/L), below the EU legal limit (100 ng/L).

Frequently asked questions
Is tap water in Fourg safe to drink?
Yes. At the check on 18 May 2026, the tap water in Fourg was within every limit tested. “EAU CONFORME (code de la santé publique). L'eau prélevée respecte les exigences de qualité réglementaire des eaux destinées à l'alimentation humaine pour les paramètres analysés. Cependant, les concentrations en chlore très élevées entraînent des désagréments pour les usagers et peuvent conduire à la production de substances organochlorées. Il con vient de maintenir un résiduel en chlore libre de 0,1 mg/l en distribu tion.”
How high are PFAS levels in Fourg's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 15 ng/L. The EU limit is 100 ng/L, so this water is at 15 % of the limit. (below the EU limit)
Does the water in Fourg also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 14 ng/L. That is 3.5 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 Fourg?
The water hardness in Fourg is 28.7 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
