How hard is the water in Schwaigern?

Zweckverband Wasserversorgungsgruppe Mühlbach publishes the hardness range 11,9 for the supply zone Aglasterhausen WS. 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: V01.02-2025-10-24, retrieved on 11/07/2026.

How much nitrate is in the drinking water in Schwaigern?

Zweckverband Wasserversorgungsgruppe Mühlbach publishes a nitrate value of 20,4 mg/l for the supply zone Aglasterhausen WS. The statutory parametric value is 50 mg/l; the measured value represents 41 % of the parametric value. Basis: V01.02-2025-10-24, retrieved on 11/07/2026.

Who supplies the drinking water in Schwaigern?

Zweckverband Wasserversorgungsgruppe Mühlbach. The values shown here come from the supply zone Aglasterhausen WS 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.
