Sources of Water
Rainwater: Rain is our main source of water. It rains when the water vapour in the air condenses. Therefore, rainwater is free from germs and soluble solid impurities. However, it contains dust particles. It also contains some dissolved gases present in the air, such as carbon dioxide. In places where the air is polluted, it may also contain harmful substances such as acids.
Groundwater: When rain falls, some of it immediately evaporates back into the atmosphere. Some runs off the surface forming streams and rivers, and some passes through the soil into the non porous rocks beneath. This is underground water or groundwater. The level of groundwater is called the water table. The groundwater may run along the surface of the non-porous rocks and come out of the surface at some places to form a natural spring. Groundwater is the source of many lakes as well.
