How hard is the water in Riggisberg?

Riggisberg publishes a total hardness of 32.13 °fH for the supply zone Riggisberg - Im Herzen des Gantrischgebietes — that corresponds to 18 °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: 2025, retrieved on 07/08/2026.

How much nitrate is in the drinking water in Riggisberg?

Riggisberg publishes a nitrate value of 0.004 mg/l for the supply zone Riggisberg - Im Herzen des Gantrischgebietes. The statutory parametric value is 40 mg/l; the measured value represents < 0.1 % of the parametric value. Basis: 2025, retrieved on 07/08/2026.

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.
