Epöl lies in the karst-rich Gerecse–Vértes area, where karst water and Danube-side wells are the usual sources; the exact supply is not confirmed here. Limestone and dolomite of the Transdanubian Mountains release calcium and magnesium into the water, which is why supplies tied to this karst are among the hardest in Hungary; the 2024 national report puts Epöl at 421.2 mg/L CaCO₃, a very hard reading. At this level scale builds quickly in heaters and washing machines, so descaling more often is needed.
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).
