How hard is the water in Herborn?

Stadtwerke Herborn GmbH publishes a total hardness of 14.2 °dH for the supply zone Burg (hardness range hart). 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: Stand 02.2025, retrieved on 11/07/2026.

How much nitrate is in the drinking water in Herborn?

Stadtwerke Herborn GmbH publishes a nitrate value of 6,4 mg/l for the supply zone Burg. The statutory parametric value is 50 mg/l; the measured value represents 13 % of the parametric value. Basis: Stand 02.2025, retrieved on 11/07/2026.

Who supplies the drinking water in Herborn?

Stadtwerke Herborn GmbH. The values shown here come from the supply zone Burg 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.
