How hard is the water in Wunstorf?

Wasserverband Nordschaumburg publishes a total hardness of 19 °dH for the supply zone Bernsen/Borstel - Kläranlage Auetal (hardness range hard). 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: 23.09.2025, retrieved on 08/07/2026.

How much nitrate is in the drinking water in Wunstorf?

Wasserverband Nordschaumburg publishes a nitrate value of 18 mg/l for the supply zone Bernsen/Borstel - Kläranlage Auetal. The statutory parametric value is 50 mg/l; the measured value represents 36 % of the parametric value. Basis: 23.09.2025, retrieved on 08/07/2026.

Who supplies the drinking water in Wunstorf?

Wasserverband Nordschaumburg. The values shown here come from the supply zone Bernsen/Borstel - Kläranlage Auetal 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.

Assigned 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 12/08/2024. 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.
