Severočeské vodovody a kanalizace (SčVK) reports 270.2 mg/L for Lesnovek in the Liberec Region, which puts it in the very hard category. The utility's published figure does not name the water source for this village, so we cannot say which supply feeds it. Expect limescale on kettles and heating elements; a descaling routine or a softener is worth considering.
Czech suppliers report "Vápník a hořčík" in mmol/L; the recommended range is 2–3.5 mmol/L.
