Drinking water in Valchava
One supply zone, water supplier: Gemeinde Rauchwart / WVA Gemeinde Rauchwart.
How to read the share of the parametric value
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.

Frequently asked questions about drinking water in Valchava
- How hard is the water in Valchava?
- Gemeinde Rauchwart / WVA Gemeinde Rauchwart publishes a total hardness of 9.5 °dH for the supply zone WVA Gemeinde Rauchwart – Ortsnetz Rauchwart (Versorgungsbereich Hochzone), Nr. 180, Zapfhahn Küche (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.
