Groundwater depletion, USGS water science

Groundwater depletion, USGS water science | Aquifers in the US | Scoop.it
Groundwater depletion, from the U.S. Geological Survey's Water Science for Schools site.

 

Groundwater is a resource found in the U.S. that is necessary to supply water for the United States. Groundwater depletion has become a common problem with groundwater use. Excessive pumping can lead to cause problems for obtaining water later. Groundwater depletion in the U.S. is found in the Southwest and High Plains for many years.

aquifer

aquifer | Aquifers in the US | Scoop.it
Encyclopedic entry. An aquifer is an underground layer of water-bearing rock. Water-bearing rocks are permeable, meaning that they have openings that liquids and gases can pass through.

 

An aquifer is a layer of rock found underground that have openings that water and gases can pass through. Aquifers fill with water and then is released through springs. There are two types of aquifers: confined and unconfined.

My scoop on Aquifers in the US

An aquifer is an area underground containing water. Unconfined aquifers consist of permeable layers of rock and sediment, which allows water to flow. Confined aquifers consist of rock and clay, or other impermeable layers which constrict water flow. Unconfined and confined aquifers have different rates of recharge, or renewal of water in the area. Unconfined aquifers have a faster rate of recharge than confined. This causes much more contact with the surface, increasing the chances of contamination.

 

Each aquifer is filled with water that is continuously moving. Depending on the permeabillity, the rate of water flow varies from 50 feet per year to 50 inches per century. Whether the flow is fast or slow, eventually the water will discharge and recharge. This means that every aquifer must contain a recharge zone and a discharge zone. Recharge zones often exist at higher altitudes, and discharge zones exist anywhere within the aquifer. Both types of zones contain flow from sources such as rain, snow, river and reservoir leakage, and even irrigation. The discharge and recharge rates must balance out in order to create a beneficial amount of water within the aquifer's region.

 

In the United States, many aquifers are struggling to keep up with our human needs for water. One major example of this issue is the Ogallala aquifer in the Great Plains. As Americans, the need for water is increasing and large amounts of water are continuously withdrawn from the Ogallala aquifer. This water is used in household, agricultural, and industrial forms. Water withdrawal is overpowering the rate of recharge in this aquifer and many others in the United States. For this reason, it is a possibility that the Great Plains region could not have enough water to satisfy their needs.

Aquifers are formation of rocks that supply water for wells and/or springs. The U.S. Geological Survey Water Resources Program determine the quantity and quality of the water supplies found in the U.S. aquifers. There is a map that shows the aquifers that supply groundwater.

Pumping Well

This image demonstrates how a pumping well functions. This is important to the topic "Aquifers in the U.S." because a pumping well plays a major role in the flow of water in an aquifer.
