Mineral composition of drinking water and daily uptake
Conductivity in mS/m or S/cm gives a rough idea of the amount of dissolved ions in water. Distilled water and reverse osmosis–treated water have extremely low conductivity, while the conductivity of water from sandstone is higher and that of water from limestone (hard water) even higher. Thus, the variation of the contribution of minerals from drinking water is large. A Swedish study on well water
