Drinking water in Gangelt, Selfkant
One supply zone, water supplier: Verbandswasserwerk Gangelt GmbH.
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.

Frequently asked questions about drinking water in Gangelt, Selfkant
- How hard is the water in Gangelt, Selfkant?
- Verbandswasserwerk Gangelt GmbH publishes the hardness range mittel for the supply zone Wasserwerk Niederbusch. 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: Geilenkirchen, Mai 2025, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Gangelt, Selfkant?
- Verbandswasserwerk Gangelt GmbH publishes a nitrate value of 20 mg/l for the supply zone Wasserwerk Niederbusch. The statutory parametric value is 50 mg/l; the measured value represents 40 % of the parametric value. Basis: Geilenkirchen, Mai 2025, retrieved on 11/07/2026.
- Who supplies the drinking water in Gangelt, Selfkant?
- Verbandswasserwerk Gangelt GmbH. The values shown here come from the supply zone Wasserwerk Niederbusch 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.
