Supply in this part of Hajdú-Bihar mostly comes from deep wells in the Great Plain's Pannonian sediments; the exact wells for Bojt are not confirmed here. Deep wells in the sediments of the Great Plain tend to give softer water than the limestone areas; the 2024 national report puts Bojt at 187.4 mg/L CaCO₃, a very hard reading. Limescale is a mild nuisance here; most households manage with occasional descaling.
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).
