How hard is the water in Postcode 3321?

Marktgemeinde Ardagger publishes a total hardness of 19.1 °dH for the supply zone 3321, Ortsnetz Ardagger Stift. 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: 2021-04-07, retrieved on 08/08/2026.

Drinking water in 3321 (Austria)

One supply zone, water supplier: Marktgemeinde Ardagger.

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.
