ENNI publishes a lab analysis of water leaving its Wittfeldstraße works, sampled on 8 June 2026, which gives 235.6 mg/L CaCO₃. This is a single sample at the works outlet, not a yearly mean, and ENNI reports analyses monthly, so the figure may move. No zone differences are published for Moers. Expect heavy scale in kettles and on taps.
German law (WRMG) uses 3 bands: soft < 8.4 °dH, medium 8.4–14 °dH, hard > 14 °dH.

What it means at home
- Severe scale: heater elements and washing-machine heaters fail early.
- Detergent use is very high; taps and screens coat within days.
- Dishwasher at maximum salt setting.
- An ion-exchange softener is practically essential; RO for drinking water.
How much salt will you use for softening?
Yes. At this hardness a softener pays for itself through appliance life and detergent.
Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).
