Drinking water in Wittlich
5 supply zones — values can differ depending on the district. Below is the zone with the most documented parameters, the others collapsed underneath. To determine the exact match, look up the postcode.
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 - Filterhaus am Schaff (WW), TWAssigned 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.

These values are more than a year old. The most recent analysis the water supplier has published for this zone dates from 05/06/2025. We have no newer values — which is why we show the latest available ones rather than none at all. They say nothing about how the water has changed since then.

| Trifluoroacetic acid (TFA) | 0,0017 mg/l | 60 µg/l UBA guide value | 3 % | Single value |
For trifluoroacetic acid (TFA), the German Drinking Water Ordinance does not specify a parametric value. The comparison is therefore made with the guide value of 60 µg/l issued by the Umweltbundesamt, which has replaced the earlier health-related guidance value of 3 µg/l. A guide value is not a legal maximum but a health-related classification.

TWIST RLP - ZHB Wittlicher Tal, Übergabe ZWEM (WW), TWAssigned 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 Wittlich
- How hard is the water in Wittlich?
- TWIST RLP - Filterhaus am Schaff (WW), TW publishes a total hardness of 2.82 mmol/l for the supply zone Filterhaus am Schaff (WW), TW — that corresponds to 15.8 °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: Publication by the water supplier, retrieved on 13/07/2026.
- How much nitrate is in the drinking water in Wittlich?
- TWIST RLP - Filterhaus am Schaff (WW), TW publishes a nitrate value of 35.5 mg/L for the supply zone Filterhaus am Schaff (WW), TW. The statutory parametric value is 50 mg/l; the measured value represents 71 % of the parametric value. Basis: Publication by the water supplier, retrieved on 13/07/2026.
- Are PFAS detectable in the drinking water in Wittlich?
- TWIST RLP - Filterhaus am Schaff (WW), TW publishes for the supply zone Filterhaus am Schaff (WW), TW a sum value PFAS-20 of 0 µg/L. The statutory parametric value is 0.1 µg/l; the measured value represents 0 % of the parametric value. For the sum of the 20 individual substances, this parametric value has applied since 12/01/2026. Basis: Publication by the water supplier, retrieved on 13/07/2026.
- Who supplies the drinking water in Wittlich?
- TWIST RLP - Filterhaus am Schaff (WW), TW. The values shown here come from the supply zone Filterhaus am Schaff (WW), TW and apply to the water the supplier delivers. What happens between the building connection and the tap — in old lead pipes, for example — is not covered by these analyses; information on that is provided by owners, the health authority or an examination by an accredited laboratory.
