Range across supply zones: 146–150 mg/L.
Stadtwerke Lutherstadt Wittenberg publishes a 2025 drinking water analysis, and the figure of 148.2 mg/L CaCO₃ is computed from it, within a narrow band of 146.4 to 149.9 mg/L. The analysis does not tell us the geology behind the supply, so we do not guess at it. Nearby Dessau-Roßlau is far harder at 392.7 mg/L, so do not carry a neighbour's figure over to Wittenberg.
German law (WRMG) uses 3 bands: soft < 8.4 °dH, medium 8.4–14 °dH, hard > 14 °dH.

What it means at home
- Fast scale on taps, shower screens and kettle; white spots on glassware.
- Water heater: efficiency loss and element failures within years if unprotected.
- Dry skin and dull hair after showering are common.
- Softener recommended; jug or reverse osmosis for drinking.
How much salt will you use for softening?
Recommended, especially with a heater or boiler: scale cuts efficiency and shortens its life.
Descale a coffee machine or kettle about every 2 months (typical manufacturer guidance for this hardness).
