Why is ground water reduceing so fast?

Normally ground water is replenished through natural processes. These can include rain and seepage from existing other sources like nearby rivers and streams. The water is purified to some extent by passing through layers of earth before it joins the underground aquifer. If it's reducing it because we are forcibly removing water at a faster rate than the natural processes can replenish it.
An aquifer can extend for miles and be tapped by multiple dwellings and/or municipalities. Each one removing water from the available reserves will effect the water available to the others. Eventually if kept unabated the shallow wells will dry up reducing the load on the aquifer, but if the draw is still greater than the natural rate of replenishment it will only be a matter of time before the aquifer doesn't contain enough water for use.
Prolonged drought, damming rivers, and natural processes of rivers changing course can all effect the rate of replenishment, in some cases causing a aquifer to dry up over time.

just wait for "global warming". I hear there will be plenty of water when the polar ice caps melt.
