Surface Water vs Ground Water
* Ground water is the water that is the resultant of the seepage of the surface water through the sub-surface.
Surface water and ground water are two terms that might appear similar in their connotations but they are different in their sense. Water collecting in a stream, river, lake or ocean is called surface water.
Surface water is subjected to the process of evaporation. Sometimes it is subjected to seepage too through sub-surface. The sub-surface seepage leads the water to the ground. It is thus observed that surface water is often subjected to precipitation.
Scientifically it has been proved that clean surface water can be used for conservation. It is at times exempted from the process of water treatment too. All you need is clean surface water for conservation. If clean surface water is used for consumption, then it might have to undergo the process of ordinary water treatment.
Medium clean fresh water is used in agriculture; of course it passes through the water treatment procedure. Fairly clean surface water is subjected to what is called rigorous water treatment process before being used up in industries.
Ground water is the water that is the resultant of the seepage of the surface water through the sub-surface. It so happens that the sub-surface seepage leads the water to the ground. It is called ground water.
There are difference sources of groundwater. The sources include connate water and magmatic water. It is to be understood that precipitation is the primary cause for the creation of groundwater. It is interesting to note that groundwater caused by the process of precipitation is called meteoric water.
Land surface water is the source of fresh water. Groundwater on the contrary is not the source for fresh water. Hence it is very important to regard surface water and groundwater as two different entities. Both of them need separate management to ensure continued water supply. Both of them need separate departments to look into their maintenance.
