Drinking water in Baden-Baden
5 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.

No date is given for these values. The water supplier publishes the analysis without a sampling date and without a report date. When the water was examined is not apparent from the source — we do not add a date and we do not estimate one. What is stated is therefore only when we retrieved the document.

Frequently asked questions about drinking water in Baden-Baden
- How hard is the water in Baden-Baden?
- Stadtwerke Baden-Baden publishes the hardness range 0,61 for the supply zone Grobbach/Plättiggruppe. 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: März 2026, retrieved on 08/07/2026.
- How much nitrate is in the drinking water in Baden-Baden?
- Stadtwerke Baden-Baden publishes a nitrate value of 2,3 mg/L for the supply zone Grobbach/Plättiggruppe. The statutory parametric value is 50 mg/l; the measured value represents 5 % of the parametric value. Basis: März 2026, retrieved on 08/07/2026.
- Who supplies the drinking water in Baden-Baden?
- Stadtwerke Baden-Baden. The values shown here come from the supply zone Grobbach/Plättiggruppe 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.
