Drinking water in 68649
One supply zone, water supplier: ENTEGA AG.
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.

ENTEGA AGAssigned 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 31/12/2023. 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.

Frequent questions about postcode 68649
- How hard is the water in Postcode 68649?
- ENTEGA AG publishes a total hardness of 3,3 mmol/l for the supply zone Versorgungsgebiet Biblis mit den Ortsteilen Nordheim und Wattenheim; Groß-Rohrheim; Herkunft: Wasserwerk Jägersburg — that corresponds to 18.5 °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: 2023, retrieved on 27/07/2026.
- How much nitrate is in the drinking water in Postcode 68649?
- ENTEGA AG publishes a nitrate value of 1,4 mg/l for the supply zone Versorgungsgebiet Biblis mit den Ortsteilen Nordheim und Wattenheim; Groß-Rohrheim; Herkunft: Wasserwerk Jägersburg. The statutory parametric value is 50 mg/l; the measured value represents 3 % of the parametric value. Basis: 2023, retrieved on 27/07/2026.
- Who supplies the drinking water in Postcode 68649?
- ENTEGA AG. The values shown here come from the supply zone Versorgungsgebiet Biblis mit den Ortsteilen Nordheim und Wattenheim; Groß-Rohrheim; Herkunft: Wasserwerk Jägersburg 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.
