Nézsa, in Nógrád county, is reported at 225.8 mg/L CaCO₃ in the NNGYK 2024 data, which is very hard. Nearby Nemti is listed at only 71.4 mg/L, so hardness differs a lot between villages in the same county. The source gives no detail on wells or zones. Limescale on heating elements is the main thing to plan for.
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).
