Drinking water in Legden
2 supply zones — values can differ depending on the district. Below is the zone with the most documented parameters, the others collapsed underneath. To determine the exact match, look up the postcode.
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.

Frequently asked questions about drinking water in Legden
- How much nitrate is in the drinking water in Legden?
- Stadtwerke Coesfeld publishes a nitrate value of 1,82 mg/l for the supply zone Coesfeld. The statutory parametric value is 50 mg/l; the measured value represents 4 % of the parametric value. Basis: Publication by the water supplier, retrieved on 25/07/2026.
- Who supplies the drinking water in Legden?
- Stadtwerke Coesfeld. The values shown here come from the supply zone Coesfeld 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.
