One supply zone, water supplier: Wasserver- und Abwasserentsorgungs-Zweckverband Region Ludwigsfelde (WARL).
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.

| Sum of PFAS | <0,000001 mg/l below limit of quantification | — | — | Mean |
| Nitrate | 0,77 mg/l | 50 mg/l | 2 % | Mean |

| Sulphate | 154,18 mg/l | 250 mg/l | 62 % | Mean |
| Sodium | 41,65 mg/l | 200 mg/l | 21 % | Mean |
* Value below the limit of quantification: the actual share of the parametric value is not known; it lies somewhere below the stated upper bound. The marker shows where the limit of quantification of the measurement lies relative to the parametric value.

Frequent questions about postcode 14974
- How hard is the water in Postcode 14974?
- Wasserver- und Abwasserentsorgungs-Zweckverband Region Ludwigsfelde (WARL) publishes a total hardness of 22.5 °dH for the supply zone Ludwigsfelde (hardness range hard). 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 11/07/2026.
- How much nitrate is in the drinking water in Postcode 14974?
- Wasserver- und Abwasserentsorgungs-Zweckverband Region Ludwigsfelde (WARL) publishes a nitrate value of 0,77 mg/l for the supply zone Ludwigsfelde. The statutory parametric value is 50 mg/l; the measured value represents 2 % of the parametric value. Basis: Publication by the water supplier, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 14974?
- Wasserver- und Abwasserentsorgungs-Zweckverband Region Ludwigsfelde (WARL). The values shown here come from the supply zone Ludwigsfelde 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.
