Nárai, in Vas county, is reported at 317.7 mg/L CaCO₃ in the NNGYK 2024 drinking-water data, which is very hard. The neighbouring village of Narda carries the same published value, so the two probably share a supply. Hungary draws most of its tap water from groundwater, and the report does not detail the source here. Descaling appliances more often is the practical consequence.
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).
