Range across supply zones: 400–450 mg/L.
Wody Miejskie Stargard states a hardness of 400 to 450 mg/L CaCO₃, and our value of 425 mg/L is the midpoint of that range, so it is a computed figure rather than a measured one. The source is a 2024 article from the utility, not a laboratory report. This is among the hardest water in this batch and scale will build up quickly in boilers and kettles.
Polish suppliers report total hardness in mg/L CaCO₃; the drinking-water regulation range is 60–500 mg/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).
