Jósvafő in Borsod-Abaúj-Zemplén county is reported at 414.1 mg/L in the NNGYK 2024 survey, which is very hard. The village lies in a karst area of northern Hungary, where limestone is common, but the survey itself gives no source details for the village. Descaling kettles and coffee machines regularly is the main practical consequence.
Hungarian suppliers report total hardness in German degrees (nk°) or mg/L CaO; the limit is 50–350 mg/L CaO.
