Drinking water in 91154
For this postcode the responsible water supplier publishes several supply zones. Which of them serves an individual address is not published — below are the values of the zone with the most documented parameters, the remaining 3 underneath.
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.

| 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.

Frequent questions about postcode 91154
- How much nitrate is in the drinking water in Postcode 91154?
- WZV Büchenbach (Wasserwerke Büchenbach) publishes a nitrate value of 20 mg/l for the supply zone WZV-Büchenbach. The statutory parametric value is 50 mg/l; the measured value represents 40 % of the parametric value. Basis: Publication by the water supplier, retrieved on 13/07/2026.
- Who supplies the drinking water in Postcode 91154?
- WZV Büchenbach (Wasserwerke Büchenbach). The values shown here come from the supply zone WZV-Büchenbach 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.
General questions — how current the data is, limit of quantification, parametric values, who is behind this site — are answered under Questions & answers.
