Drinking water in 54516
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 4 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: Wasserwerk nach Aufbereitung
Stadtwerke WittlichAssigned 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 05/06/2025. 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.

|---|---|---|---|---|
| Trifluoroacetic acid (TFA) | 0,0017 mg/l | 60 µg/l UBA guide value | 3 % | Single 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 54516
- How hard is the water in Postcode 54516?
- Stadtwerke Wittlich publishes a total hardness of 2,89 mmol/l for the supply zone Stadt: Wasserwerk nach Aufbereitung — that corresponds to 16.2 °dH. 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: 05.06.2025, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Postcode 54516?
- Stadtwerke Wittlich publishes a nitrate value of 36 mg/l for the supply zone Stadt: Wasserwerk nach Aufbereitung. The statutory parametric value is 50 mg/l; the measured value represents 72 % of the parametric value. Basis: 05.06.2025, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 54516?
- Stadtwerke Wittlich. The values shown here come from the supply zone Stadt: Wasserwerk nach Aufbereitung 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.
