NNGYK's 2024 data report 380.2 mg/L hardness as CaCO3 for Martonfa in Baranya county, which is very hard. The entry does not state the water source, and we have not verified it. Expect strong scale in kettles and water heaters, so a softener or scale protection is worth considering.
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).
