Drinking water in 91334
One supply zone, water supplier: Wasserzweckverband Hemhofen (wzvb.de).
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.

Frequent questions about postcode 91334
- How hard is the water in Postcode 91334?
- Wasserzweckverband Hemhofen (wzvb.de) publishes the hardness range 2 - mittel for the supply zone Hemhofen - Röttenbach. 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: 15.04.2026, retrieved on 08/07/2026.
