How hard is the water in Kleinarl?

Gemeinde Kleinarl (GD Kleinarl, TWA) publishes a total hardness of 1,72 mmol/l for the supply zone Dorf 30 / Netzprobe Gemeindeamt — that corresponds to 9.6 °dH. 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: 19.11.2025, retrieved on 11/08/2026.

How much nitrate is in the drinking water in Kleinarl?

Gemeinde Kleinarl (GD Kleinarl, TWA) publishes a nitrate value of <1 mg/l for the supply zone Dorf 30 / Netzprobe Gemeindeamt. The statutory parametric value is 50 mg/l; the measured value lies below it and cannot be specified more precisely below the limit of quantification. Basis: 19.11.2025, retrieved on 11/08/2026.

3 supply zones — values can differ depending on the district. Below is the zone with the most documented parameters, the others collapsed underneath. To determine the exact match, look up the postcode.

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.

Annual means and medians are not individual measured values, but the parametric values apply per sample. If a mean lies above it, at least one individual sample was above it — the mean does not say how many, or by how much. That is why this is not reported here as an exceedance of the parametric value. What counts remains the water supplier's publication, which each row links to.
