Drinking water in Heikendorf

One supply zone, water supplier: Gemeindewerke Heikendorf AöR.

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.

Frequently asked questions about drinking water in Heikendorf

How hard is the water in Heikendorf?
Gemeindewerke Heikendorf AöR publishes a total hardness of 17.4 °dH for the supply zone Heikendorf (hardness range hart). 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: Analyse durch LUFA-ITL vom April 2026, retrieved on 14/07/2026.
How much nitrate is in the drinking water in Heikendorf?
Gemeindewerke Heikendorf AöR publishes a nitrate value of 1,93 mg/l for the supply zone Heikendorf. The statutory parametric value is 50 mg/l; the measured value represents 4 % of the parametric value. Basis: Analyse durch LUFA-ITL vom April 2026, retrieved on 14/07/2026.
Who supplies the drinking water in Heikendorf?
Gemeindewerke Heikendorf AöR. The values shown here come from the supply zone Heikendorf 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.
