Drinking water in 53909
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 3 underneath.
How to read the share of the parametric value
12 % Share of the parametric value. The proportion of the permitted maximum that the measured value uses — here 12 %, so just over an eighth.
< 10 % * Below the limit of quantification. The substance was not detectable. The mark shows where the detection limit lies relative to the parametric value — the actual share of the parametric value is below that.
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.

Frequent questions about postcode 53909
- How hard is the water in Postcode 53909?
- Wasserleitungszweckverband der Neffeltalgemeinden publishes a total hardness of 21.1 °dH for the supply zone WW Embken Ausgang, 52385 Nideggen-Embken, Neffeltalstr. (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: Druckdatum: 27.04.2026, Version 1; Geprüft und freigegeben: 27.04.2026, retrieved on 13/07/2026.
- How much nitrate is in the drinking water in Postcode 53909?
- Wasserleitungszweckverband der Neffeltalgemeinden publishes a nitrate value of 13 mg/l for the supply zone WW Embken Ausgang, 52385 Nideggen-Embken, Neffeltalstr.. The statutory parametric value is 50 mg/l; the measured value represents 26 % of the parametric value.

- Who supplies the drinking water in Postcode 53909?
- Wasserleitungszweckverband der Neffeltalgemeinden. The values shown here come from the supply zone WW Embken Ausgang, 52385 Nideggen-Embken, Neffeltalstr. 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.
