Drinking water in Braunwald
One supply zone, water supplier: Rottenmann.
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 Braunwald
- How hard is the water in Braunwald?
- Rottenmann publishes a total hardness of 0,265 mmol/l for the supply zone 2 HB Stadtwald — that corresponds to 1.5 °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: 21.10.2025, retrieved on 11/08/2026.
- How much nitrate is in the drinking water in Braunwald?
- Rottenmann publishes a nitrate value of 3,1 mg/l for the supply zone 2 HB Stadtwald. The statutory parametric value is 50 mg/l; the measured value represents 6 % of the parametric value. Basis: 21.10.2025, retrieved on 11/08/2026.
- Who supplies the drinking water in Braunwald?
- Rottenmann. The values shown here come from the supply zone 2 HB Stadtwald 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.
