Ground water is a valuable resource both in the United States and throughout the world. Where surface water, such as lakes and rivers, are scarce or inaccessible, ground water supplies many of the hydrologic needs of people everywhere. In the United States. It is the source of drinking water for about half the total population and nearly all of the rural population, and it provides over 50 billion gallons per day for agricultural needs. Ground-water depletion, a term often defined as long-term water-level declines caused by sustained ground-water pumping, is a key issue associated with ground-water use. Many areas of the United States are experiencing ground-water depletion.

The water stored in the ground can be compared to money kept in a bank account. If you withdraw money at a faster rate than you deposit new money you will eventually start having account-supply problems. Pumping water out of the ground faster than it is replenished over the long-term causes similar problems. The volume of ground water in storage is decreasing in many areas of the United States in response to pumping. Ground-water depletion is primarily caused by sustained ground-water pumping. Some of the negative effects of ground-water depletion:

* drying up of wells
* reduction of water in streams and lakes
* deterioration of water quality
* increased pumping costs
* land subsidence

I've heard of this in context of dehydration. Your body uses water to cool itself, either in keeping your orifaces moist or through sweat. Sweat cools the body by using body heat to evaporate the sweat on your skin. As that liquid evaporates or is absorbed into your clothing the water is lost to your body. Simularly as you breathe you exhale water vapor that was keeping your mouth and throat moist. This water exits the body through breath and is depleted. During times of high body temp or heavy breathing we deplete water faster, hence why it's important to drink water when excert yourself.

The water is running low. Not as much water as is normal.

Depleted means a supply of something has gotten low, due to, TOO much use of it.
