Drinking water in 65817
One supply zone, water supplier: Eppstein.
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.
Eppstein
EppsteinAssigned 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 27/03/2025. 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.
| Parameter | Value | Parametric value | Share of the parametric value | Reference |
|---|---|---|---|---|
| Nitrate | 15,8 mg/l | 50 mg/l | 32 % | Single value |
| Lead | <0,001 mg/l below limit of quantification | 10 µg/l | < 10 % * | Single value |
| Sulphate | 40 mg/l | 250 mg/l | 16 % | Single value |
| Sodium | 20,2 mg/l | 200 mg/l | 10 % | Single value |
* 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 65817
- How hard is the water in Postcode 65817?
- Eppstein publishes a total hardness of 11 °dH for the supply zone Eppstein (hardness range medium). 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: Publication by the water supplier, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Postcode 65817?
- Eppstein publishes a nitrate value of 15,8 mg/l for the supply zone Eppstein. The statutory parametric value is 50 mg/l; the measured value represents 32 % of the parametric value. Basis: Publication by the water supplier, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 65817?
- Eppstein. The values shown here come from the supply zone Eppstein 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.
