Drinking water in 25980
One supply zone, water supplier: Energieversorgung Sylt (EVS).
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.

Chemical parameters (5)
| Parameter | Value | Parametric value | Share of the parametric value | Reference |
|---|---|---|---|---|
| Fluoride | <0,05 mg/l below limit of quantification | 1.5 mg/l | < 3 % * | Single value |
| Lead | <0,001² mg/l not detectable | 10 µg/l | — | Single value |
| Mercury | <0,0003² mg/l not detectable | 1 µg/l | — | Single value |
| Nitrate | 14,1 mg/l | 50 mg/l | 28 % | Single value |
| Nitrite | <0,005² mg/l not detectable | 0.5 mg/l | — | Single 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.

Frequent questions about postcode 25980
- How hard is the water in Postcode 25980?
- Energieversorgung Sylt (EVS) publishes a total hardness of 4 °dH for the supply zone sylt gesamt (hardness range soft). 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: Stand: März 2026, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Postcode 25980?
- Energieversorgung Sylt (EVS) publishes a nitrate value of 14,1 mg/l for the supply zone sylt gesamt. The statutory parametric value is 50 mg/l; the measured value represents 28 % of the parametric value. Basis: Stand: März 2026, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 25980?
- Energieversorgung Sylt (EVS). The values shown here come from the supply zone sylt gesamt 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.
