Stadtwerke Glückstadt publishes its hardness for the Krempermoor waterworks, and the 2026 figure is 135.7 mg/L CaCO₃. That is hard but softer than Elmshorn (258.8 mg/L) and Itzehoe (219.6 mg/L) nearby. The source page lists a single value, so there is no zone breakdown. Occasional descaling is enough in most households.
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).
