Drinking water in Sonnefeld
One supply zone, water supplier: SWN.
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 Sonnefeld
- How hard is the water in Sonnefeld?
- SWN publishes the hardness range 6,76 for the supply zone HB 3000. 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 Sonnefeld?
- SWN publishes a nitrate value of 25 mg/l for the supply zone HB 3000. The statutory parametric value is 50 mg/l; the measured value represents 50 % of the parametric value. Basis: Publication by the water supplier, retrieved on 11/07/2026.
- Who supplies the drinking water in Sonnefeld?
- SWN. The values shown here come from the supply zone HB 3000 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.
