water table is important process which makes the water availability in the ground. In rainy season when water droplets falls on the ground it gets absorbed by the groung through the combination of several process. Water went down through the pores which is present in the between the space. Through these pores the droplets goes down and then it gets trapped in the stones which are present below the the upper layer of the soil. through this process these water collected down in the bottom and when the drilling occurs or well is constructed then through these collected water we are able to get the water . The point at which these water starts coming is known as the water table.
When these water absorbed by the soil then the priocess of purification also done as these water goes though the sand and also through porous sands ao muds. These water table is free from harmful bacteria and also free from several impurities. water table are best and fit for the drinking without any filtration.
Today it went down because of several factors like construction of these builing makes less space to be use for the absorption of the water droplets. But now these water table is also got polluted by the chemical and also the sewage system which mainly very depth and able to pollute these water. Now we need to take some steps so that we can make it as it is previously.
If we will not take any steps soon then our water table water also become the sewage like water..... in coming future.
