Drinking water in Tattendorf
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 Tattendorf
- How hard is the water in Tattendorf?
- Viteos publishes a total hardness of 30.7 °f for the supply zone Chauffage à distance, 26.03 — that corresponds to 17.2 °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: Février 2026, retrieved on 12/08/2026.
- How much nitrate is in the drinking water in Tattendorf?
- Viteos publishes a nitrate value of 13.1 mg/L for the supply zone Chauffage à distance, 26.03. The statutory parametric value is 40 mg/l; the measured value represents 33 % of the parametric value. Basis: Février 2026, retrieved on 12/08/2026.
- Who supplies the drinking water in Tattendorf?
- Viteos. The values shown here come from the supply zone Chauffage à distance, 26.03 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.
