Drinking water in Altötting
One supply zone, water supplier: Stadt Altötting.
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.

* 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.

Frequently asked questions about drinking water in Altötting
- How much nitrate is in the drinking water in Altötting?
- Stadt Altötting publishes a nitrate value of 1,1 mg/l for the supply zone Ortsnetz der Kreisstadt Altötting, der Stadt Neuötting und der Gemeinde Winhöring. The statutory parametric value is 50 mg/l; the measured value represents 2 % of the parametric value. Basis: Publication by the water supplier, retrieved on 11/07/2026.
- Who supplies the drinking water in Altötting?
- Stadt Altötting. The values shown here come from the supply zone Ortsnetz der Kreisstadt Altötting, der Stadt Neuötting und der Gemeinde Winhöring 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.
