Source of water

SOURCES OF WATER

The water source can be sub devided into four major parts 

1. Surface water :-

As the word surface states that the water which lies over surface of the earth is known as surface water it may be still water or it may be following water like sea and river respectively

IT IS FURTHER SUB GROUPED IN TWO MAIN CATEGORIES 

¤FLOWING WATER :- This source of water consisting the water source which is seems to be following over the earth surface mainly streams and river water falls in this catogeries mainly the source of river water is mealting of snow,springs and rain 

Even we can't be able to use the river water for the domestic purposes as well as industrial purposes because it contains fine particles of sand and several soluble minerals  

It also contains minerals of soil like chloride, sulphate, bicarbonates of sodium, calcium, iron and magnessium

It also contaminated by the organic west like decomposition of plants and animals ,so it is not fit for the domestic purposes 

River water

Still water :- In this catogeries the source which is not following on the earth surface comes the main source comes of still water are lake, ponds and reservoirs lake water is less contiminates then of river water it contains much lesser amount of dissolve minerals but the continuation of organic west in the still water is much greater than the flowing water

• 

Sea water 

2.Underground water :- As the word underground refers that the water source which is found deep inside the ground is known as ground water besides this underground water is free from several organic inpurities and also from several contaminants it is clear in appearance due to the filteration action of the soil ,gravets and other several layers 

Due to presence of dissolve minerals it is hard in nature and due to its taste it can be used for the drinking purpose but also it is not fit for the industrial uses tube wells ,springs, and wells are the some examples of underground water 

Tube wells 

3. Sea water :- As we studied above that the largest area of earth is covered with the oceans and sea this source of water is impure due to the dissolved impurities which includes the release of industrial as well as domestic waste inside the sea an another reason is that the continious evopuration of the sea water increases the dissolved impurities in the water 
Also this water is not suitable for drinking as well as industrial uses

3. Rain water :- This water source is familiar with everyone this source of water is obtained by the evopuration of the surface water 
It is purest form of natural water but while comming to the earth it is contiminated with the harmfull gasses present in the environment the gasses such as oxides of carbon ,nitrogen ,and sulphur contiminates this water supply 
Besides this dur to its irregular supply it becomes combursome and much expensive to store this water
