Drinking water in 91186
One supply zone, water supplier: WZV Büchenbach (Wasserwerke Büchenbach).
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.
WZV-Büchenbach
WZV Büchenbach (Wasserwerke Büchenbach)Assigned via the water supplier — the exact supply zone boundary within the postcode is not yet linked.
No date is given for these values. The water supplier publishes the analysis without a sampling date and without a report date. When the water was examined is not apparent from the source — we do not add a date and we do not estimate one. What is stated is therefore only when we retrieved the document.
| Parameter | Value | Parametric value | Share of the parametric value | Reference |
|---|---|---|---|---|
| Nitrate | 20 mg/l | 50 mg/l | 40 % | Single value |
| Lead | <0,003 mg/l below limit of quantification | 10 µg/l | < 30 % * | Single value |
| Sulphate | 24 mg/l | 250 mg/l | 10 % | Single value |
| Sodium | 12 mg/l | 200 mg/l | 6 % | Single value |
* 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.
