PWiK Przemyśl's 2025 water quality notice gives 170 mg/L CaCO₃, in the hard category. That is softer than most cities in the lowlands of central and western Poland. The notice gives a single value for the city, so we show no range. Some scale on kettles and heaters is likely, but it builds up slower than in very hard areas.
Polish suppliers report total hardness in mg/L CaCO₃; the drinking-water regulation range is 60–500 mg/L.

How much salt will you use for softening?
Recommended, especially with a heater or boiler: scale cuts efficiency and shortens its life.
Descale a coffee machine or kettle about every 2 months (typical manufacturer guidance for this hardness).
