PFAS in Chambray's tap water: 2.2 ng/L, 4.4x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
4.4× 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 Chambray, the 4 most closely watched PFAS (PFAS-4) add up to 2.2 ng/L (0.0022 µg/L) at the latest PFAS check on 26 February 2025. That's 4.4 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 5.4 ng/L (0.0054 µg/L), below the EU legal limit (100 ng/L).

Frequently asked questions
Is tap water in Chambray safe to drink?
Yes. At the check on 15 June 2026, the tap water in Chambray was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés. Toutefois, la présence de bactéries aérobies revivifiables en quantité importante est observée.”
How high are PFAS levels in Chambray's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 5.4 ng/L. The EU limit is 100 ng/L, so this water is at 5 % of the limit. (below the EU limit)
Does the water in Chambray 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 2.2 ng/L stays below.
How hard is the water in Chambray?
The water hardness in Chambray is 32.1 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
