Supply in Baranya comes mainly from groundwater, including karst of the Mecsek and wells in the Drava and Danube valleys; the exact source for Siklós is not confirmed here. Limestone in the Mecsek and carbonate-rich valley sediments explain the high calcium content; for Siklós the 2024 national report gives 385.5 mg/L CaCO₃ (very hard). Expect heavy limescale in kettles, boilers and on taps; descaling and a softener are worth considering.
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).
