Drinking water quality in Wisches
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. (2 April 2025)
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 latest official test passed all quality requirements.
„Eau destinée à la consommation humaine conforme aux limites de qualité réglementaires pour les paramètres analysés. La concentration des bactéries revivifiables à 22°C et/ou à 36°C est importante. Elles ne présentent pas de risque pour la santé humaine. Si nécessaire, le distributeur d'eau doit effectuer une purge du réseau d'eau potable. Eau douce très faiblement minéralisée (conductivité inférieure à 200 µs/cm) susceptible, dans certaines conditions défavorables (stagna tion, chauffe-eau...) de dissoudre certains métaux des canalisations. Le matin ou après quelques jours d'absence, il est conseillé de ne con sommer l'eau du robinet qu'après un écoulement de 15 à 30 secondes. Vérifiez l'absence de canalisations en plomb dans les parties privatives du réseau.“

Frequently asked questions
Is tap water in Wisches safe to drink?
Yes. The latest official test (17 June 2026) checked the tap water in Wisches and it passed every requirement.
How high are PFAS levels in Wisches'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 Wisches 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 Wisches?
The water hardness in Wisches is 3.2 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 28 August 2026.
