Drinking water in 77855
For this postcode Stadtwerke Achern publishes several supply zones. Which of them serves an individual address is not published — below are the values of the zone with the most documented parameters, the remaining 1 underneath.
How to read the share of the parametric value
Several samples per year: for chemical parameters the mean value is given, for microbiological ones the highest measured value. There the parametric value is zero — a single finding would disappear in the average, and it is precisely that finding which is the information. Which reference applies is stated in the last column of the table.
ON Achern (ZWV 5. Achern ON Achern (Feuerwehrhaus), Alter Bahnhof)
Stadtwerke AchernAssigned via the water supplier — the exact supply zone boundary within the postcode is not yet linked.
These values are more than a year old. The most recent analysis the water supplier has published for this zone dates from 02/05/2025. We have no newer values — which is why we show the latest available ones rather than none at all. They say nothing about how the water has changed since then.

Frequent questions about postcode 77855
- How much nitrate is in the drinking water in Postcode 77855?
- Stadtwerke Achern publishes a nitrate value of 31 mg/l for the supply zone ON Achern (ZWV 5. Achern ON Achern (Feuerwehrhaus), Alter Bahnhof). The statutory parametric value is 50 mg/l; the measured value represents 62 % of the parametric value. Basis: 02.05.2025, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 77855?
- Stadtwerke Achern. The values shown here come from the supply zone ON Achern (ZWV 5. Achern ON Achern (Feuerwehrhaus), Alter Bahnhof) and apply to the water the supplier delivers. What happens between the building connection and the tap — in old lead pipes, for example — is not covered by these analyses; information on that is provided by owners, the health authority or an examination by an accredited laboratory.
