Drinking water in Blankenburg, Oberharz am Brocken
7 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 Blankenburg, Oberharz am Brocken
- How hard is the water in Blankenburg, Oberharz am Brocken?
- WAHB publishes a total hardness of 6.5 °dH for the supply zone Benneckenstein Elbingerode Elend Schierke Sorge Tanne Rübeland einschließlich Kreuztal, ausgenommen Neuwerk (hardness range weich). 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: Juni 2025, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Blankenburg, Oberharz am Brocken?
- WAHB publishes a nitrate value of 11 mg/l for the supply zone Benneckenstein Elbingerode Elend Schierke Sorge Tanne Rübeland einschließlich Kreuztal, ausgenommen Neuwerk. The statutory parametric value is 50 mg/l; the measured value represents 22 % of the parametric value. Basis: Juni 2025, retrieved on 11/07/2026.
- Who supplies the drinking water in Blankenburg, Oberharz am Brocken?

The values shown here come from the supply zone Benneckenstein Elbingerode Elend Schierke Sorge Tanne Rübeland einschließlich Kreuztal, ausgenommen Neuwerk 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.
