How hard is the water in Leopoldsdorf?

EVN Wasser GesmbH publishes a total hardness of 10.8 °dH for the supply zone 2333, Leopoldsdorf (hardness range medium). 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: 2026-01-27, retrieved on 08/07/2026.

How much nitrate is in the drinking water in Leopoldsdorf?

EVN Wasser GesmbH publishes a nitrate value of 8,3 mg/l for the supply zone 2333, Leopoldsdorf. The statutory parametric value is 50 mg/l; the measured value represents 17 % of the parametric value. Basis: 2026-01-27, retrieved on 08/07/2026.

Who supplies the drinking water in Leopoldsdorf?

EVN Wasser GesmbH. The values shown here come from the supply zone 2333, Leopoldsdorf and apply to the water the supplier delivers.

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.
