Tereske, in Nógrád county, is reported at 502.4 mg/L as CaCO₃ in the 2024 NNGYK report. This is very hard and just above our review threshold, so it was checked before publication. We could not verify the water source, so confirm with the local utility if you plan a purchase.
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).
