NNGYK's 2024 report gives Rónabánya, in Nógrád county, 514 mg/L as CaCO₃, which is very hard and above our usual 500 mg/L review threshold, so the value needs data-auditor confirmation. The report does not name the supply source. If confirmed, expect heavy scale and consider a softener.
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).
