Drinking water in Nußdorf am Haunsberg, Obertrum am See, Seekirchen am Wallersee
One supply zone, water supplier: Marktgemeinde Obertrum am See.
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.

Frequently asked questions about drinking water in Nußdorf am Haunsberg, Obertrum am See, Seekirchen am Wallersee
- How hard is the water in Nußdorf am Haunsberg, Obertrum am See, Seekirchen am Wallersee?
- Marktgemeinde Obertrum am See publishes a total hardness of 2,96 mmol/l for the supply zone GD Obertrum, TWA; Spielberggrabenquellen - PN Spielberggraben, Zulauf QSS oro re — that corresponds to 16.6 °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: 14.04.2026, retrieved on 14/08/2026.
- How much nitrate is in the drinking water in Nußdorf am Haunsberg, Obertrum am See, Seekirchen am Wallersee?
- Marktgemeinde Obertrum am See publishes a nitrate value of 3,9 mg/l for the supply zone GD Obertrum, TWA; Spielberggrabenquellen - PN Spielberggraben, Zulauf QSS oro re. The statutory parametric value is 50 mg/l; the measured value represents 8 % of the parametric value. Basis: 14.04.2026, retrieved on 14/08/2026.
- Who supplies the drinking water in Nußdorf am Haunsberg, Obertrum am See, Seekirchen am Wallersee?
