The Edwards Aquifer is one of the most prolific artesian aquifers in the world. Located on the eastern edge of the Edwards Plateau in the U.S. state of Texas, it is the source of drinking water for two million people, and is the primary water supply for agriculture and industry in the aquifer’s region.
How many aquifers are in Texas?
The Texas Water Development Board (TWDB) recognizes 9 major aquifers − aquifers that produce large amounts of water over large areas (see major aquifers map) − and 22 minor aquifers − aquifers that produce minor amounts of water over large areas or large amounts of water over small areas (see minor aquifers map).
Where is the biggest aquifer in Texas?
Ogallala Aquifer
Summary. The Ogallala Aquifer is the largest aquifer in the United States and is a major aquifer of Texas underlying much of the High Plains region.
How deep is the aquifer in Texas?
The depth to the water table of the Ogallala Aquifer varies from actual surface discharge to over 150 meters (500 feet). Generally, the aquifer is found from 15 to 90 meters (50 to 300 feet) below the land surface. The saturated thickness also varies greatly.
Where does Texas get its water supply?
About 60 percent of the approximately 16 million acre-feet of water used yearly in Texas is derived from underground formations that make up 9 major and 22 minor aquifers. Groundwater also supplies about 35 percent of the municipal needs of the state.
Who owns the aquifers in Texas?
Landowners
Who Owns the Groundwater? Landowners in Texas own the water beneath their property. See Texas Water Code Section 36.002. Moreover, recent case law makes clear that a landowner owns not only the water that emerges from the ground, but the water in place underground as well.
What is the main aquifer in Texas?
The Ogallala aquifer extends through 48 counties of the Texas Panhandle and is the southernmost extension of the largest aquifer (High Plains aquifer) in North America.
How much longer will the Ogallala Aquifer last?
Once depleted, the aquifer will take over 6,000 years to replenish naturally through rainfall.
Where do Texans get most of their drinking water?
Groundwater provides an estimated* Nine major aquifers and 22 minor aquifers supply 62% of all the water used in the state. Also, 1,320,000 Texans rely on groundwater from their own wells for their drinking water and use 137 million gallons per day.
What would happen if all the aquifers in Texas dried up?
This is the breadbasket of America—the region that supplies at least one fifth of the total annual U.S. agricultural harvest. If the aquifer goes dry, more than $20 billion worth of food and fiber will vanish from the world’s markets.
What is Texas main water source?
groundwater
About 60 percent of all water used in the state is groundwater, and the other 40 percent of the water is from surface water. Most of the groundwater – about 80 percent – is used for irrigation. Communities use perhaps 15 percent of all the groundwater in the state.
Can I drill a water well on my property in Texas?
Groundwater in Texas is governed by the legal doctrine known as the Rule of Capture. Under the Rule of Capture, a landowner needs no permit to drill a well and pump groundwater, and he may pump as much water as he may beneficially use even if that causes his neighbor’s well to go dry.
What are two major aquifers in Texas?
Major Aquifers. The major aquifers in Texas include the Ogalalla aquifer, the Gulf Coast aquifer, the Edwards aquifer , Carrizo-Wilcox aquifer, Edwards-Trinity (Plateau) aquifer, the Seymour aquifer, the Hueco- Mesilla Bolson, and the Cenozoic Pecos aquifer.
What is the largest aquifer in Texas?
The Ogallala Aquifer is the largest aquifer in the United States and is a major aquifer of Texas underlying much of the High Plains region. The aquifer consists of sand, gravel, clay, and silt and has a maximum thickness of 800 feet. Freshwater saturated thickness averages 95 feet.
How many aquifers is there in Texas?
The state of Texas covers 23 aquifers (7 major and 16 minor aquifers) that underlie approximately ¾ of the state. The Ogallala Aquifer accounts for about 90% of the water in all of Texas aquifers.
Where are aquifer locations?
The Ogallala Aquifer , or High Plains Aquifer, is a vast yet shallow aquifer located beneath the Great Plains in the United States. One of the world’s largest aquifers, it lies under about 174,000 mi² (450,000 km²) in portions of South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas.
