PFAS in the tap water of Ormes (Marne): 7 ng/L, 14x our 0.5 ng/L benchmark

Last PFAS check: · Source: Hub'eau

PFAS in drinking water

14× above our health benchmark

Amount found in the water 7 ng/L 0.007 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).

In Ormes, the 4 most closely watched PFAS (PFAS-4) add up to 7 ng/L (0.007 µg/L) at the latest PFAS check on 6 May 2025. That's 14 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 13 ng/L (0.013 µg/L), below the EU legal limit (100 ng/L).

Frequently asked questions

Is tap water in Ormes safe to drink?

All the values shown here (17 July 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “L'eau distribuée présente des concentrations en pesticides supérieures aux exigences réglementaires fixées à 0,1 µg/l, mais inférieures aux valeurs définies pour en limiter les usages sanitaires. Un contrôle renforcé est en place et des actions sont engagées par l’exploitant pour restaurer la qualité de l’eau. Cette eau est de bonne qualité pour les autres paramètres. Elle peut être consommée par tous.”

How high are PFAS levels in Ormes's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 13 ng/L. The EU limit is 100 ng/L, so this water is at 13 % of the limit. (below the EU limit)

Does the water in Ormes also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 7 ng/L. That is 1.75 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 Ormes?

The water hardness in Ormes is 37.7 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?
