Drinking water quality in Mommenheim
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at <0,005 µg/L. The EU limit is 0.1 µg/L, so this water is at 0 % of the limit. (20 February 2026)
The four most harmful PFAS add up to 0 µg/L, below the health limit of 0.004 µg/L used in Sweden since 2026.
Substances too small to measure count as 0, so the real total may be higher.

Official assessment
The authorities have not published an overall verdict for this water.
„Eau d'alimentation non conforme aux limites de qualité réglementaire e n vigueur. La concentration d’un métabolite de pesticide (chloridazone desphényl) est supérieure à la limite de qualité réglementaire en vigueur (0,1 µ g/L). La quantification de cette molécule dans l’eau à une concentration inf érieure à sa valeur dérogatoire, bien que constituant une non-conformi té réglementaire, ne présente pas de risque sanitaire pour le consomma teur. L’eau peut être consommée sans restriction. Un suivi renforcé spécifique est mis en œuvre sur plusieurs points de surveillance du réseau d’eau potable en vue d’évaluer l’évolution des concentrations des paramètres concernés.“

Frequently asked questions
Is tap water in Mommenheim safe to drink?
All the values shown here (11 May 2026) are within the legal limits, but the authorities have not published an overall verdict for this water.
How high are PFAS levels in Mommenheim's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at <0,005 µg/L. The EU limit is 0.1 µg/L, so this water is at 0 % of the limit. (below the EU limit)
Does the water in Mommenheim also meet the strictest limits in Europe?
Yes. Even against Europe's strictest limit, the health limit of 0.004 µg/L used in Sweden since 2026, the measured value of 0 µg/L stays below.
How hard is the water in Mommenheim?
The water hardness in Mommenheim is 40.9 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
