Drinking water in Obersulm
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 Obersulm
- How hard is the water in Obersulm?
- Zweckverband Sulmwasserversorgungsgruppe / Gemeinde Obersulm (geliefert durch Zweckverband Wasserversorgung Nordostwürttemberg NOW) publishes a total hardness of 1,62 mol/m³ for the supply zone Affaltrach, Eschenau, Sülzbach und Willsbach — that corresponds to 9.1 °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: Publication by the water supplier, retrieved on 08/07/2026.
- How much nitrate is in the drinking water in Obersulm?
- Zweckverband Sulmwasserversorgungsgruppe / Gemeinde Obersulm (geliefert durch Zweckverband Wasserversorgung Nordostwürttemberg NOW) publishes a nitrate value of 3,9 mg/L for the supply zone Affaltrach, Eschenau, Sülzbach und Willsbach. The statutory parametric value is 50 mg/l; the measured value represents 8 % of the parametric value. Basis: Publication by the water supplier, retrieved on 08/07/2026.
- Who supplies the drinking water in Obersulm?
- Zweckverband Sulmwasserversorgungsgruppe / Gemeinde Obersulm (geliefert durch Zweckverband Wasserversorgung Nordostwürttemberg NOW). The values shown here come from the supply zone Affaltrach, Eschenau, Sülzbach und Willsbach 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.
