One supply zone, water supplier: Gemeindewerke Wachtendonk.
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.

| Parameter | Value | Parametric value | Share of the parametric value | Reference |
|---|---|---|---|---|
| Nitrate | <0,5 mg/l below limit of quantification | 50 mg/l | < 1 % * | Single value |
| Sulphate | 9 mg/l | 250 mg/l | 4 % | Single value |
| Sodium | 6,0 mg/l | 200 mg/l | 3 % | Single value |
* Value below the limit of quantification: the actual share of the parametric value is not known; it lies somewhere below the stated upper bound. The marker shows where the limit of quantification of the measurement lies relative to the parametric value.
