Drinking water in 21398
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 1 underneath.
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.
Stadt Lüneburg, WBV Lüneburg-Süd (SG Ostheide)
Wasserversorgung LüneburgAssigned via the water supplier — the exact supply zone boundary within the postcode is not yet linked.
These values are more than a year old. The most recent analysis the water supplier has published for this zone dates from 08/03/2017. We have no newer values — which is why we show the latest available ones rather than none at all. They say nothing about how the water has changed since then.

* 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.
For trifluoroacetic acid (TFA), the German Drinking Water Ordinance does not specify a parametric value. The comparison is therefore made with the guide value of 60 µg/l issued by the Umweltbundesamt, which has replaced the earlier health-related guidance value of 3 µg/l. A guide value is not a legal maximum but a health-related classification.

Frequent questions about postcode 21398
- How hard is the water in Postcode 21398?
- Wasserversorgung Lüneburg publishes a total hardness of 4.7 °dH for the supply zone Stadt Lüneburg, WBV Lüneburg-Süd (SG Ostheide) (hardness range I). 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: 08.03.2017, retrieved on 13/07/2026.
- How much nitrate is in the drinking water in Postcode 21398?
- Wasserversorgung Lüneburg publishes a nitrate value of 0,2 mg/L for the supply zone Stadt Lüneburg, WBV Lüneburg-Süd (SG Ostheide). The statutory parametric value is 50 mg/l; the measured value represents 0.4 % of the parametric value. Basis: 08.03.2017, retrieved on 13/07/2026.
- Who supplies the drinking water in Postcode 21398?
- Wasserversorgung Lüneburg. The values shown here come from the supply zone Stadt Lüneburg, WBV Lüneburg-Süd (SG Ostheide) 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.
