Drinking water in Jonen
One supply zone, water supplier: Gemeinde Jonen.
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.
Wasserversorgung der Gemeinde Jonen
Gemeinde JonenAssigned 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 31/12/2024. 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.

* Value below the limit of quantification: the actual share of the parametric value is not known; it lies somewhere below the stated upper bound. The marker shows where the limit of quantification of the measurement lies relative to the parametric value.

Frequently asked questions about drinking water in Jonen
- How hard is the water in Jonen?
- Gemeinde Jonen publishes a total hardness of 32.9 °fH for the supply zone Wasserversorgung der Gemeinde Jonen — that corresponds to 18.4 °dH. 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. Basis: 2024, retrieved on 07/08/2026.
- How much nitrate is in the drinking water in Jonen?
- Gemeinde Jonen publishes a nitrate value of 28 mg/l for the supply zone Wasserversorgung der Gemeinde Jonen. The statutory parametric value is 40 mg/l; the measured value represents 70 % of the parametric value. Basis: 2024, retrieved on 07/08/2026.
- Who supplies the drinking water in Jonen?
- Gemeinde Jonen. The values shown here come from the supply zone Wasserversorgung der Gemeinde Jonen 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.
