Minerals add flavour. Naturally sourced Bottled Waters have different concentrations of minerals in them, depending on the geology of the land that they come from, which gives each bottled water its taste.
The most common minerals found in mineral waters are Calcium, Magnesium, Sodium, Potassium, and Bicarbonate. Typical values mg / L for Aqua Pura – Calcium 19, Magnesium 7, Potassium 3, Sodium 11, Bicarbonate 55, Chloride 15, Sulphate 14, Nitrate 20, pH (at Source) 6.4.
