Drinking water in 4791 (Austria)
For this postcode Marktgemeinde Schardenberg publishes several supply zones. Which of them serves an individual address is not published — below are the values of the zone with the most documented parameters, the remaining 1 underneath.
The values come from the Austrian drinking water database, to which water suppliers report voluntarily. In each case the highest value of the published range is given.
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.
