Rátka, in Borsod-Abaúj-Zemplén county, is reported at 423.0 mg/L CaCO₃, which is very hard. The figure is taken from the NNGYK 2024 drinking-water quality register. We do not have verified details on the local supply, so this is the published settlement value only. Limescale on heating elements and taps will build up quickly without treatment.
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).
