There is belief by some consumers that natural mineral waters have medicinal properties or offer other health benefits. Such waters typically of high mineral content sometimes significantly higher the concentrations normally accepted in drinking water.The mineral content of any bottled water is dependent on the nature of the strata which the water is abstracted the solubility of the minerals and the contact time with the water.
Some highly mineralized waters have very complicated hydrogeological origins, and some are naturally carbonated due to upwelling of carbon dioxide.
Packaged waters with very low mineral content, such as distilled or demineralized waters are also consumed. Rainwater, which is similarly low in minerals, is consumed by some populations without apparent adverse health effects.
