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.

How hard is the water in Postcode 26723?
Stadtwerke Emden GmbH (Emder Wasser) publishes a total hardness of 9.9 °dH for the supply zone Wasserwerk Tergast – Stadtgebiet Emden (ausgenommen Wybelsum und Twixlum), Reinwasser (hardness range medium). 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: März 2026, retrieved on 11/07/2026.
How much nitrate is in the drinking water in Postcode 26723?
Stadtwerke Emden GmbH (Emder Wasser) publishes a nitrate value of 2,40 mg/l for the supply zone Wasserwerk Tergast – Stadtgebiet Emden (ausgenommen Wybelsum und Twixlum), Reinwasser. The statutory parametric value is 50 mg/l; the measured value represents 5 % of the parametric value. Basis: März 2026, retrieved on 11/07/2026.
