How hard is the water in Straß im Straßertale?

EVN Wasser GesmbH publishes a total hardness of 13.3 °dH for the supply zone 3491, Elsarn (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.

How much nitrate is in the drinking water in Straß im Straßertale?

EVN Wasser GesmbH publishes a nitrate value of 14 mg/l for the supply zone 3491, Elsarn. The statutory parametric value is 50 mg/l; the measured value represents 28 % of the parametric value. Basis: 2026-01-27, retrieved on 08/07/2026.

Who supplies the drinking water in Straß im Straßertale?

EVN Wasser GesmbH. The values shown here come from the supply zone 3491, Elsarn 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.

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.
