Kópháza in Győr-Moson-Sopron county is reported at 431.9 mg/L in the NNGYK 2024 survey, which is very hard. The survey does not name the source for the village, so the cause is not confirmed here. Scale forms quickly in kettles and boilers, and a softener or scale protection is worth considering.
Hungarian suppliers report total hardness in German degrees (nk°) or mg/L CaO; the limit is 50–350 mg/L CaO.
