Drinking water in 14542

For this postcode Wasser- und Abwasserzweckverband Werder-Havelland (WAZV) publishes several supply zones. Which of them serves an individual address is not published — below are the values of the zone with the most documented parameters, the remaining 3 underneath.

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.

Wasser- und Abwasserzweckverband Werder-Havelland (WAZV)

Assigned via the water supplier — the exact supply zone boundary within the postcode is not yet linked.

These values are more than a year old. The most recent analysis the water supplier has published for this zone dates from 16/04/2024. 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.

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.

Frequent questions about postcode 14542

How hard is the water in Postcode 14542?
Wasser- und Abwasserzweckverband Werder-Havelland (WAZV) publishes a total hardness of 3,5 mmol/l for the supply zone Netzproben WAZV Werder-Havelland - Ferch, Potsdamer Platz 9, Amt Schwielowsee — that corresponds to 19.6 °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: 29.04.2024, retrieved on 11/07/2026.
How much nitrate is in the drinking water in Postcode 14542?
Wasser- und Abwasserzweckverband Werder-Havelland (WAZV) publishes a nitrate value of <0,00300 (NWG) mol/m³ for the supply zone Netzproben WAZV Werder-Havelland - Ferch, Potsdamer Platz 9, Amt Schwielowsee. The statutory parametric value is 50 mg/l; the measured value lies below it and cannot be specified more precisely below the limit of quantification. Basis: 29.04.2024, retrieved on 11/07/2026.
Who supplies the drinking water in Postcode 14542?
Wasser- und Abwasserzweckverband Werder-Havelland (WAZV). The values shown here come from the supply zone Netzproben WAZV Werder-Havelland - Ferch, Potsdamer Platz 9, Amt Schwielowsee 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.
