About three quarters of the earth's surface is covered with liquid water. In vapour form water is also an important constituent of the earth's atmosphere. In combined for water occurs in minerals (for example in gypsum). More over, water occurs in animals and vegetable tissues. It constitutes about 70 percent of the human body and over 90 percent of some vegetables

Naturally occurring waters frequently contain dissolved mineral substances. We have mineral waters in which the total mineral content is significantly above the average.

Potable water is water which is fit to drink. Since water dissolves a part of everything with which it comes in contact, absolutely pure water does not occur in nature.

The water for drinking and domestic purposes is generally supplied by rivers, lakes, wells and springs. Such waters usually contain salts of calcium, iron, magnesium, potassium, sodium, organic matters and traces of different gases from the atmosphere. There is also a variety of suspended matter in natural water. Good drinking water must be free from toxic salts, disease producing organisms and from harmful contamination.nking and domestic purp is general ly supplied by rivers, lakes, wells and springs.
