Drinking water in Bichl
One supply zone, water supplier: Gemeinde Bichl.
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.

Frequently asked questions about drinking water in Bichl
- How hard is the water in Bichl?
- Gemeinde Bichl publishes a total hardness of 3,6 mmol/l for the supply zone Hochbehälter, Zapfhahn 1230/0173/15101, 83673 Bichl — that corresponds to 20.2 °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: 06.10.2025, retrieved on 08/08/2026.
