MPWiK Puławy measured the blended water in the first half of 2026 at 280 mg/L CaCO₃. The result is for mixed water from the network and comes without a range, so we cannot show variation between districts. It is very hard water. Descaling of kettles, boilers and washing machines will be needed regularly.
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).
