How hard is the water in Postcode 38855?

Stadtwerke Wernigerode GmbH publishes a total hardness of 4.2 °dH for the supply zone Versorgungsbereich Wasserwerk Wienrode (Fremdbezug); Entnahmestelle: HALBERSTADT WW KLUS FERNWASSER (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: 28.01.2026, retrieved on 11/07/2026.

Who supplies the drinking water in Postcode 38855?

Stadtwerke Wernigerode GmbH. The values shown here come from the supply zone Versorgungsbereich Wasserwerk Wienrode (Fremdbezug); Entnahmestelle: HALBERSTADT WW KLUS FERNWASSER 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.

Drinking water in 38855

Q: How much nitrate is in the drinking water in Postcode 38855?

Stadtwerke Wernigerode GmbH publishes a nitrate value of 9,2 mg/l for the supply zone Versorgungsbereich Wasserwerk Wienrode (Fremdbezug); Entnahmestelle: HALBERSTADT WW KLUS FERNWASSER. The statutory parametric value is 50 mg/l; the measured value represents 18 % of the parametric value. Basis: 28.01.2026, retrieved on 11/07/2026.

For this postcode the responsible water supplier publishes several supply zones. Which of them serves an individual address is not published — below are the values of the zone with the most documented parameters, the remaining 9 underneath.

How to read the share of the parametric value

12 % Share of the parametric value. The proportion of the permitted maximum that the measured value uses — here 12 %, so just over an eighth.

< 10 % * Below the limit of quantification. The substance was not detectable. The mark shows where the detection limit lies relative to the parametric value — the actual share of the parametric value is below that.

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.
