Sulphates are sulphur compounds. In natural mineral water sulphate typically occurs in significant quantities when the mineral water comes from gypsum-bearing bedrock.
Mineral waters that have more than 200 milligrams of sulphate per liter are defined as being rich in sulphate. A high sulphate content can give mineral waters a slightly bitter taste.
