Sources of Water

Ground Water:-
Water that is hidden underground in spaces between soil and rock particlesis known as ground water.
Surface Water:-
After precipitation, the amount of water that does not percolate down into the ground or does not return to the atmosphere by evaporation or transpiration and enters the rivers, streams, lakes, ponds, wetland, or artificial reservoirs constitutes surface water.
Effects of Over-utilization of Ground Water
Reduced flow of surface water
Lowering of water table
Water logging
Subsidence
Degradation of water quality
Increased salt content
Increased power costs
