How hard is the water in Postcode 5421?

Gemeinde Adnet publishes a total hardness of 2,48 mmol/l for the supply zone Brunnen Waidach — that corresponds to 13.9 °dH. 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: 20.06.2024, retrieved on 14/08/2026.

Who supplies the drinking water in Postcode 5421?

Gemeinde Adnet. The values shown here come from the supply zone Brunnen Waidach 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 5421 (Austria)

For this postcode Gemeinde Adnet 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 2 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.
