PFAS in Chambilly'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
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 Artaix, on the same distribution network as Chambilly (SOLOGNE LIGERIENNE). 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).
More PFAS than in 93% of the cities we track

In Chambilly, the 4 most closely watched PFAS (PFAS-4) add up to 6 ng/L (0.006 µg/L) at the latest PFAS check on 20 August 2025. 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: 7 ng/L (0.007 µg/L), below the EU legal limit (100 ng/L).

Frequently asked questions
Is tap water in Chambilly safe to drink?
Yes. At the check on 20 May 2026, the tap water in Chambilly was within every limit tested. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité. L'eau ne respecte pas la référence de qualité pour le paramètre carbone organique total.”
How high are PFAS levels in Chambilly's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 7 ng/L. The EU limit is 100 ng/L, so this water is at 7 % of the limit. (below the EU limit)
Does the water in Chambilly 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 Chambilly?
The water hardness in Chambilly is 15.8 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
