For water put into bottles or containers which is naturally rich in or artificially enriched with carbon dioxide, the minimum value may be lower.\nIron\n200\nμg/l\nManganese\n50\nμg/l\nOdour\nAcceptable to consumers and no abnormal change\nOxidisability\n5,0\nmg/l O2\nThis parameter need not be measured if the parameter TOC is analysed.\nSulphate\n250\nmg/l\nThe water should not be corrosive.\nSodium\n200\nmg/l\nTaste\nAcceptable to consumers and no abnormal change\nColony count 22o C\nNo abnormal change\nColiform bacteria\n0\nnumber/100 ml\nFor water put into bottles or containers, the unit is number/250 ml.\nTotal organic carbon (TOC)\nNo abnormal change\nThis parameter need not be measured for supplies of less than 10 000 m3 a day.\nTurbidity\nAcceptable to consumers and no abnormal change\nWater should not be aggressive or corrosive. This applies particularly to water undergoing treatment (demineralization, softening, membrane treatment, reverse osmosis, etc.).\nWhere water intended for human consumption is derived from treatment that significantly demineralizes or softens water, calcium and magnesium salts could be added to condition the water in order to reduce any possible negative health impact, as well as to reduce the corrosiveness or aggressivity of water and to improve taste. Minimum concentrations of calcium and magnesium or total dissolved solids in softened or demineralized water could be established taking into account the characteristics of water that enters those processes.",
