Drinking water in 81825
One supply zone, water supplier: Stadtwerke München.
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.

Frequent questions about postcode 81825
- How much nitrate is in the drinking water in Postcode 81825?
- Stadtwerke München publishes a nitrate value of 6,5 mg/l for the supply zone gesamtes Stadtgebiet. The statutory parametric value is 50 mg/l; the measured value represents 13 % of the parametric value. Basis: Januar 2026, retrieved on 11/07/2026.
- Are PFAS detectable in the drinking water in Postcode 81825?
- Stadtwerke München publishes for the supply zone gesamtes Stadtgebiet a sum value PFAS-20 below the limit of quantification (entry in the report: "< 0,000030 mg/l"). This is not to be read as "PFAS-free": below the limit of quantification, the measurement cannot make any statement. The statutory parametric value is 0.1 µg/l; the measured value lies below it and cannot be specified more precisely below the limit of quantification. For the sum of the 20 individual substances, this parametric value has applied since 12/01/2026. Basis: Januar 2026, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 81825?
- Stadtwerke München. The values shown here come from the supply zone gesamtes Stadtgebiet 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.
