What exactly is “pure water”?
If you look at nature, water evaporates into the atmosphere and comes down as rain. Water in the clouds is in its purest natural form only H2O with virtually no minerals no impurities. When water falls on ground, it encounters suspended materials chemical, bacteria and viruses contained in the atmospheres. It further dissolves impurities like calcium, magnesium, sodium and fluorides etc. when it seeps into the earth. Pure water has virtually no minerals it is only ‘H2O’.
