Drinking water in 15827
One supply zone, water supplier: Wasser- und Abwasserzweckverband Blankenfelde-Mahlow (WAZ).
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 15827
- How hard is the water in Postcode 15827?
- Wasser- und Abwasserzweckverband Blankenfelde-Mahlow (WAZ) publishes a total hardness of 11.1 °dH for the supply zone Groß Schulzendorf (hardness range medium). 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 Postcode 15827?
- Wasser- und Abwasserzweckverband Blankenfelde-Mahlow (WAZ) publishes a nitrate value of 0,84 mg/l for the supply zone Groß Schulzendorf. The statutory parametric value is 50 mg/l; the measured value represents 2 % of the parametric value. Basis: Publication by the water supplier, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 15827?
- Wasser- und Abwasserzweckverband Blankenfelde-Mahlow (WAZ). The values shown here come from the supply zone Groß Schulzendorf 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.
