PFAS in drinking water

38× above our health benchmark

Amount found in the water 19 ng/L 0.019 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.

Sample taken in Vireux-Molhain, on the same distribution network as Montigny-sur-Meuse (MONTIGNY SUR MEUSE). 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).

PFAS over time in Montigny-sur-Meuse

19 PFAS checks since 6 February 2024, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Montigny-sur-Meuse.

“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions

Is tap water in Montigny-sur-Meuse safe to drink?

Yes. At the check on 15 June 2026, the tap water in Montigny-sur-Meuse 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 Montigny-sur-Meuse's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 23 ng/L. The EU limit is 100 ng/L, so this water is at 23 % of the limit. (below the EU limit)

Does the water in Montigny-sur-Meuse also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 19 ng/L. That is 4.8 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).

Are PFAS levels rising in Montigny-sur-Meuse's tap water?

Calculated PFAS-4 values are listed in the table. The chart uses laboratory-published sum-of-20 results; there are too few laboratory-published PFAS-4 sums for the existing trend calculation.

How hard is the water in Montigny-sur-Meuse?

The water hardness in Montigny-sur-Meuse is 25.7 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
