Kács, in Borsod-Abaúj-Zemplén county, is reported at 346.2 mg/L hardness as CaCO3 in the 2024 NNGYK data, which is very hard. The dataset does not identify the supply source, so we make no claim about it. Hard water at this level typically leaves scale in kettles, boilers and on glass, and shortens appliance life if untreated.
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).
