ČEVAK reports 308.3 mg/L CaCO₃ for Plíškovice, which is very hard and well above most South Bohemian villages in this dataset. The utility page does not name the source, so the reason is not confirmed. Scale will build up quickly in kettles and water heaters, and a softener is worth considering.
Czech suppliers report "Vápník a hořčík" in mmol/L; the recommended range is 2–3.5 mmol/L.
