Drinking water in 46414

One supply zone, water supplier: Stadtwerke Rhede.

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.

Assigned 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 13/10/2023. 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.

Frequent questions about postcode 46414

How hard is the water in Postcode 46414?
Stadtwerke Rhede publishes a total hardness of 19.1 °dH for the supply zone rhede gesamt (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: Stand vom 13.10.2023, retrieved on 11/07/2026.
How much nitrate is in the drinking water in Postcode 46414?
Stadtwerke Rhede publishes a nitrate value of 6,9 mg/l for the supply zone rhede gesamt. The statutory parametric value is 50 mg/l; the measured value represents 14 % of the parametric value. Basis: Stand vom 13.10.2023, retrieved on 11/07/2026.
Who supplies the drinking water in Postcode 46414?
Stadtwerke Rhede. The values shown here come from the supply zone rhede 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.
