Drinking water in Salmtal
One supply zone, water supplier: TWIST RLP - Obere Salm, Übergabe ZWEM (WW), TW VGW Wittlich-Land.
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.

TWIST RLP - Obere Salm, Übergabe ZWEM (WW), TW VGW Wittlich-LandAssigned via the water supplier — the exact supply zone boundary within the postcode is not yet linked.
No date is given for these values. The water supplier publishes the analysis without a sampling date and without a report date. When the water was examined is not apparent from the source — we do not add a date and we do not estimate one. What is stated is therefore only when we retrieved the document.

Frequently asked questions about drinking water in Salmtal
- How hard is the water in Salmtal?
- TWIST RLP - Obere Salm, Übergabe ZWEM (WW), TW VGW Wittlich-Land publishes a total hardness of 0.55 mmol/l for the supply zone Obere Salm, Übergabe ZWEM (WW), TW VGW Wittlich-Land — that corresponds to 3.1 °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.
