Much of Pest county is supplied from riverbank-filtered Danube wells, though some towns use local wells; the exact source for Tököl is not confirmed here. Water filtered through the Danube's gravel banks carries calcium and magnesium from limestone and dolomite in the river's catchment, which usually makes it hard; the 2024 national report puts Tököl at 259.7 mg/L CaCO₃, a very hard reading. Limescale appears on kettles and taps within weeks, and heating appliances need regular 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).
