Drinking water in Dollern
10 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.

* Value below the limit of quantification: the actual share of the parametric value is not known; it lies somewhere below the stated upper bound. The marker shows where the limit of quantification of the measurement lies relative to the parametric value.
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.

Frequently asked questions about drinking water in Dollern
- How hard is the water in Dollern?
- Trinkwasserverband Stader Land publishes a total hardness of 12.2 °dH for the supply zone Dollern (hardness range Mittel). 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 25/07/2026.
- How much nitrate is in the drinking water in Dollern?
- Trinkwasserverband Stader Land publishes a nitrate value of 6,1 mg/l for the supply zone Dollern. The statutory parametric value is 50 mg/l; the measured value represents 12 % of the parametric value. Basis: 02.04.2026, retrieved on 25/07/2026.
- Who supplies the drinking water in Dollern?
- Trinkwasserverband Stader Land. The values shown here come from the supply zone 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.
