Mosonmagyaróvár lies in the Győr–Sopron area, where supply comes from gravel-bed wells in the Danube plain (Szigetköz) and from local wells; the exact source is not confirmed here. Water taken from the Danube's gravel beds is typically hard; the 2024 national report lists Mosonmagyaróvár at 239.2 mg/L CaCO₃ (very hard). Visible limescale on taps and in kettles is normal at this level, and dishwasher salt is recommended.
Hungarian suppliers report total hardness in German degrees (nk°) or mg/L CaO; the limit is 50–350 mg/L CaO.

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).
