The 2024 NNGYK drinking-water quality data for Somogyviszló report 357.0 mg/L as CaCO₃, which is very hard. We have not confirmed the exact source for this village, but most drinking water in Hungary comes from groundwater, which often picks up calcium and magnesium from carbonate-rich rock. Expect limescale on kettles and heating elements.
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).
