Drinking water in 51467
One supply zone, water supplier: BELKAW GmbH (RheinEnergie-Gruppe).
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.

BELKAW GmbH (RheinEnergie-Gruppe)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 31/12/2019. 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.
| Parameter | Value | Parametric value | Share of the parametric value | Reference |
|---|---|---|---|---|
| Nitrate | 19 ± 1 mg/l | 50 mg/l | — | Mean |
| Lead | <0,0005 mg/l below limit of quantification | 10 µg/l | < 5 % * | Mean |
| Escherichia coli (E. coli) | 0 /100 ml | 0/100 ml | — | Mean |
| Sulphate | 57 ± 6 mg/l | 250 mg/l | — | Mean |
| Sodium | 22 ± 3 mg/l | 200 mg/l | — | Mean |
* Value below the limit of quantification: the actual share of the parametric value is not known; it lies somewhere below the stated upper bound. The marker shows where the limit of quantification of the measurement lies relative to the parametric value.
