NNGYK's 2024 drinking-water report lists Erdőszőlő, in Pest county, at 205.2 mg/L CaCO3, which falls in the very hard band. The published entry does not name the supply source, so treat this as the reported figure for the village, not a statement about the aquifer. At this level, scale on kettles and heating elements is likely, and a descaling routine or softener is 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).
