Drinking water in 65527
One supply zone, water supplier: Gemeinde Niedernhausen.
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.

Gemeinde NiedernhausenAssigned 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 23/04/2024. 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 65527
- How hard is the water in Postcode 65527?
- Gemeinde Niedernhausen publishes a total hardness of 6.8 °dH for the supply zone Niedernhausen, Leitungswasser Ortsnetz, Tiefzone, Kindergarten Ahornstr.11, Hahn Übergabestelle (hardness range soft). The hardness range is a classification under the German Detergents and Cleaning Products Act (soft below 8,4 °dH, medium 8,4 to 14 °dH, hard above that) and not a quality verdict — it indicates how much calcium and magnesium is dissolved in the water.

- Gemeinde Niedernhausen publishes a nitrate value of 8,1 mg/l for the supply zone Niedernhausen, Leitungswasser Ortsnetz, Tiefzone, Kindergarten Ahornstr.11, Hahn Übergabestelle. The statutory parametric value is 50 mg/l; the measured value represents 16 % of the parametric value. Basis: Erstellt: 17.06.2024; Freigegeben: 27.06.2024, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 65527?
- Gemeinde Niedernhausen. The values shown here come from the supply zone Niedernhausen, Leitungswasser Ortsnetz, Tiefzone, Kindergarten Ahornstr.11, Hahn Übergabestelle 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.
