Drinking water in Warngau
One supply zone, water supplier: WBV Oberwarngau.
How to read the share of the parametric value
12 % Share of the parametric value. The proportion of the permitted maximum that the measured value uses — here 12 %, so just over an eighth.
< 10 % * Below the limit of quantification. The substance was not detectable. The mark shows where the detection limit lies relative to the parametric value — the actual share of the parametric value is below that.
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.

Frequently asked questions about drinking water in Warngau
- How hard is the water in Warngau?
- WBV Oberwarngau publishes a total hardness of 3,4 mmol/l for the supply zone Rathaus, Keller, Zulauf, Zapfhahn - Taubenbergstraße 33, 83627 Warngau — that corresponds to 19.1 °dH. The hardness range is a classification under the German Detergents and Cleaning Products Act (soft below 8,4 °dH, medium 8,4 to 14 °dH, hard above that) and not a quality verdict — it indicates how much calcium and magnesium is dissolved in the water. Basis: 24.06.2026, retrieved on 08/08/2026.
- How much nitrate is in the drinking water in Warngau?
- WBV Oberwarngau publishes a nitrate value of 8,5 mg/l for the supply zone Rathaus, Keller, Zulauf, Zapfhahn - Taubenbergstraße 33, 83627 Warngau. The statutory parametric value is 50 mg/l; the measured value represents 17 % of the parametric value. Basis: 24.06.2026, retrieved on 08/08/2026.
- Are PFAS detectable in the drinking water in Warngau?
- WBV Oberwarngau states for the supply zone Rathaus, Keller, Zulauf, Zapfhahn - Taubenbergstraße 33, 83627 Warngau that the sum PFAS-20 was not detectable (entry in the report: "n.n."). 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: 24.06.2026, retrieved on 08/08/2026.
- Who supplies the drinking water in Warngau?
- WBV Oberwarngau. The values shown here come from the supply zone Rathaus, Keller, Zulauf, Zapfhahn - Taubenbergstraße 33, 83627 Warngau 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.
