Drinking water in Oberlunkhofen
One supply zone, water supplier: VWV Oberlunkhofen Arni Islisberg.
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.
