Range across supply zones: 350–375 mg/L.
Lithuanian public supply relies largely on groundwater from deep aquifers, which are rich in dissolved carbonates. The reported hardness is 362.8 mg/L CaCO₃, with measurements from 350.3 to 375.3 mg/L. Limescale builds quickly in kettles, boilers and washing machines, so frequent descaling or a softener is worth considering.
Lithuanian suppliers report total hardness in mmol/L.

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).
