For about 14.6% of the Earth's Fresh water supply comes from ground water. The share of the liquid fresh water of the Earth that accounts for ground water is about 94.05%. The two geological roles of ground water are given below: It acts as an erosional agent. It acts as a stream flow equalizer, i. e., it is a sort of storage form in order to provide sustainability to the streams during dry periods. For about 23% of U. S fresh water is provided by ground water. Most of the ground water is utilized for irrigation purposes.
