Drinking water in Alle
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 Alle
- How hard is the water in Alle?
- Commune d'Alle publishes a total hardness of 28.4 °f for the supply zone Août — that corresponds to 15.9 °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.

- How much nitrate is in the drinking water in Alle?
- Commune d'Alle publishes a nitrate value of 12.6 mg/l for the supply zone Août. The statutory parametric value is 40 mg/l; the measured value represents 32 % of the parametric value. Basis: Édition, octobre 2025, retrieved on 12/08/2026.
- Who supplies the drinking water in Alle?
