Drinking water in Fachbach, Exklave Lahnstein

One supply zone, water supplier: TWIST RLP - Fachbach-Nievern TZ-Miellen.

How to read the share of the parametric value

12 % Share of the parametric value. The proportion of the permitted maximum that the measured value uses — here 12 %, so just over an eighth.
< 10 % * Below the limit of quantification. The substance was not detectable. The mark shows where the detection limit lies relative to the parametric value — the actual share of the parametric value is below that.

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.

Assigned 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.
