Drinking water in Rettenbach
There are 2 places with this name — listed below by area. 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 Rettenbach
- How hard is the water in Rettenbach?
- Stadtwerke Günzburg KU publishes a total hardness of 17.7 °dH for the supply zone Günzburg (hardness range hart). 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: Publication by the water supplier, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Rettenbach?
- Stadtwerke Günzburg KU publishes a nitrate value of 10,1 mg/l for the supply zone Günzburg. The statutory parametric value is 50 mg/l; the measured value represents 20 % of the parametric value. Basis: Publication by the water supplier, retrieved on 11/07/2026.
- Who supplies the drinking water in Rettenbach?
- Stadtwerke Günzburg KU. The values shown here come from the supply zone Günzburg 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.
