Narda, in Vas county, has a published hardness of 317.7 mg/L CaCO₃ (NNGYK, 2024), in the very hard category. Nárai nearby has an identical figure, which suggests a shared supply, though the source does not state this. Most water in Hungary comes from groundwater, so hardness mainly reflects the rock of the aquifer. Expect scale in kettles and water heaters.
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).
