Drinking water in 47546
One supply zone, water supplier: Stadtwerke Kalkar.
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.

Frequent questions about postcode 47546
- How hard is the water in Postcode 47546?
- Stadtwerke Kalkar publishes a total hardness of 11 °dH for the supply zone Hochbehälter Monreberg, Kalkar (Entnahmestelle: TW Monreberg Kalkar, Ablauf Behälter 07-0940) (hardness range mittel). 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: Publication by the water supplier, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Postcode 47546?
- Stadtwerke Kalkar publishes a nitrate value of 15,9 mg/l for the supply zone Hochbehälter Monreberg, Kalkar (Entnahmestelle: TW Monreberg Kalkar, Ablauf Behälter 07-0940). The statutory parametric value is 50 mg/l; the measured value represents 32 % of the parametric value. Basis: Publication by the water supplier, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 47546?
- Stadtwerke Kalkar. The values shown here come from the supply zone Hochbehälter Monreberg, Kalkar (Entnahmestelle: TW Monreberg Kalkar, Ablauf Behälter 07-0940) 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.
