How hard is the water in Postcode 59505?

Wasserwerke Westfalen GmbH publishes a total hardness of 7.5 °dH for the supply zone Wasserwerk Echthausen (hardness range weich). 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: Quartals-Mittel 2026/1, retrieved on 17/08/2026.

How much nitrate is in the drinking water in Postcode 59505?

Wasserwerke Westfalen GmbH publishes a nitrate value of 11,7 mg/l for the supply zone Wasserwerk Echthausen. The statutory parametric value is 50 mg/l; the measured value represents 23 % of the parametric value. Basis: Quartals-Mittel 2026/1, retrieved on 17/08/2026.

Who supplies the drinking water in Postcode 59505?

Wasserwerke Westfalen GmbH. The values shown here come from the supply zone Wasserwerk Echthausen 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.
