What are the 3 largest aquifers in Texas?
This system has been divided into three major water-producing components referred to as the Chicot, Evangeline, and Jasper aquifers. In 2008, municipal uses accounted for 62 percent and irrigation accounted for 25 percent of the total pumpage from the aquifer.
Where are aquifers located in Texas?
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 deep is the Texas aquifer?
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.
How far down is the water table in Texas?
The water table has demonstrated no long-term trends since ground-water development began, with the probable exception of the water table in the Katy area: There the water table is more than 75 feet deep, probably due to ground-water pumpage from deeper zones.
How many major aquifers are 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. Groundwater from Texas aquifers is used for irrigation, municipal use, manufacturing, and livestock production.
How long until the Ogallala Aquifer runs out?
Within 50 years, the entire aquifer is expected be 70% depleted. Some observers blame this situation on periodic drought. Others point to farmers, since irrigation accounts for 90% of Ogallala groundwater withdrawals.
How do I find out how deep the water table in my area?
The most reliable method of obtaining the depth to the water table at any given time is to measure the water level in a shallow well with a tape. If no wells are available, surface geophysical methods can sometimes be used, depending on surface accessibility for placing electric or acoustic probes.
What happens if the Ogallala Aquifer dries up?
If the aquifer goes dry, more than $20 billion worth of food and fiber will vanish from the world’s markets. And scientists say it will take natural processes 6,000 years to refill the reservoir.
What is the main problem that has developed in the Ogallala Aquifer?
The Ogallala Aquifer is being both depleted and polluted. Irrigation withdraws much groundwater, yet little of it is replaced by recharge. Since large-scale irrigation began in the 1940s, water levels have declined more than 30 meters (100 feet) in parts of Kansas, New Mexico, Oklahoma, and Texas.
What will happen when the Ogallala Aquifer dries up?
