Drinking water in 23684
One supply zone, water supplier: ZVO Energie GmbH.
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.

| Parameter | Value | Parametric value | Share of the parametric value | Reference |
|---|---|---|---|---|
| Nitrate | 2,17 mg/l | 50 mg/l | 4 % | Maximum · Süsel |
| Lead | < 0,001 mg/l below limit of quantification | 10 µg/l | < 10 % * | Maximum · Süsel |
| Sulphate | 34,6 mg/l | 250 mg/l | 14 % | Maximum · Süsel |
| Sodium | 26,2 mg/l | 200 mg/l | 13 % | Maximum · Süsel |
* 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.

* 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.

Frequent questions about postcode 23684
- How hard is the water in Postcode 23684?
- ZVO Energie GmbH publishes a total hardness of 17.9 °dH for the supply zone Süsel (hardness range hard). 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: 03.06.2026, retrieved on 25/07/2026.
- How much nitrate is in the drinking water in Postcode 23684?
- ZVO Energie GmbH publishes a nitrate value of 2,17 mg/l for the supply zone Süsel. The statutory parametric value is 50 mg/l; the measured value represents 4 % of the parametric value. Basis: 03.06.2026, retrieved on 25/07/2026.
- Who supplies the drinking water in Postcode 23684?
- ZVO Energie GmbH. The values shown here come from the supply zone Süsel 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.
