How hard is the water in Postcode 3820?

EVN Wasser GesmbH publishes a total hardness of 15.7 °dH for the supply zone 3820, Liebnitz. Hardness indicates how much calcium and magnesium are dissolved in the water. It is not a quality assessment: there is no parametric value for hardness. Basis: 2026-02-11, retrieved on 08/07/2026.

How much nitrate is in the drinking water in Postcode 3820?

EVN Wasser GesmbH publishes a nitrate value of 14 mg/l for the supply zone 3820, Liebnitz. The statutory parametric value is 50 mg/l; the measured value represents 28 % of the parametric value. Basis: 2026-02-11, retrieved on 08/07/2026.

Who supplies the drinking water in Postcode 3820?

EVN Wasser GesmbH. The values shown here come from the supply zone 3820, Liebnitz 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.

Drinking water in 3820 (Austria)

For this postcode the responsible water supplier publishes several supply zones. Which of them serves an individual address is not published — below are the values of the zone with the most documented parameters, the remaining 4 underneath.

The values come from the Austrian drinking water database, to which water suppliers report voluntarily. In each case the highest value of the published range is given.

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.

3820, WV-20

TWG-Lindau

Assigned via the water supplier — the exact supply zone boundary within the postcode is not yet linked.

These values are more than a year old. The most recent analysis the water supplier has published for this zone dates from 18/02/2025. We have no newer values — which is why we show the latest available ones rather than none at all. They say nothing about how the water has changed since then.
