Drinking water in 69254
One supply zone, water supplier: Wassergewinnungszweckverband Hardtwald (Rhein-Neckar-Kreis).
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.

Frequent questions about postcode 69254
- How hard is the water in Postcode 69254?
- Wassergewinnungszweckverband Hardtwald (Rhein-Neckar-Kreis) publishes a total hardness of 3.15 mmol/l for the supply zone St. Leon-Rot, Mühlhausen, Rauenberg und Malsch — that corresponds to 17.7 °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: 04.02.2026, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Postcode 69254?
- Wassergewinnungszweckverband Hardtwald (Rhein-Neckar-Kreis) publishes a nitrate value of 4,4 mg/l for the supply zone St. Leon-Rot, Mühlhausen, Rauenberg und Malsch. The statutory parametric value is 50 mg/l; the measured value represents 9 % of the parametric value. Basis: 04.02.2026, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 69254?
- Wassergewinnungszweckverband Hardtwald (Rhein-Neckar-Kreis). The values shown here come from the supply zone St. Leon-Rot, Mühlhausen, Rauenberg und Malsch 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.
