Drinking water in 21730

For this postcode Trinkwasserverband Stader Land 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 6 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.

An exceedance of a parametric value does not automatically mean a health risk; the statutory parametric values include safety margins. Assessment and any measures are the responsibility of the competent health authority of the respective country.

Frequent questions about postcode 21730

How hard is the water in Postcode 21730?
Trinkwasserverband Stader Land publishes the hardness range Mittel for the supply zone Wasserwerk Dollern. 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: 02.04.2026, retrieved on 13/07/2026.
How much nitrate is in the drinking water in Postcode 21730?
Trinkwasserverband Stader Land publishes a nitrate value of 6,1 mg/l for the supply zone Wasserwerk Dollern. The statutory parametric value is 50 mg/l; the measured value represents 12 % of the parametric value. Basis: 02.04.2026, retrieved on 13/07/2026.
Who supplies the drinking water in Postcode 21730?
Trinkwasserverband Stader Land. The values shown here come from the supply zone Wasserwerk Dollern 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.

General questions — how current the data is, limit of quantification, parametric values, who is behind this site — are answered under Questions & answers.
