Drinking water in Mellingen
2 supply zones — values can differ depending on the district. Below is the zone with the most documented parameters, the others collapsed underneath. To determine the exact match, look up the postcode.
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 Mellingen
- How hard is the water in Mellingen?
- Wasserversorgung Stadt Mellingen publishes a total hardness of 36.75 °fH for the supply zone Hochzone — that corresponds to 20.6 °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: 2025, retrieved on 07/08/2026.
- How much nitrate is in the drinking water in Mellingen?
- Wasserversorgung Stadt Mellingen publishes a nitrate value of 25 mg/l for the supply zone Hochzone. The statutory parametric value is 40 mg/l; the measured value represents 63 % of the parametric value. Basis: 2025, retrieved on 07/08/2026.
- Who supplies the drinking water in Mellingen?
- Wasserversorgung Stadt Mellingen. The values shown here come from the supply zone Hochzone 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.
