PFAS in Flassigny's tap water: 3 ng/L, 6x our 0.5 ng/L benchmark

Last PFAS check: · Source: Hub'eau

PFAS in drinking water

6× above our health benchmark

Amount found in the water 3 ng/L 0.003 µg/L · the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

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).

More PFAS than in 88% of the cities we track

In Flassigny, the 4 most closely watched PFAS (PFAS-4) add up to 3 ng/L (0.003 µg/L) at the latest PFAS check on 18 April 2025. That's 6 times our 0.5 ng/L health benchmark, but below 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 Flassigny safe to drink?

Yes. At the check on 1 June 2026, the tap water in Flassigny 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 Flassigny'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 Flassigny 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 3 ng/L stays below.

How hard is the water in Flassigny?

The water hardness in Flassigny is 22.1 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
