What is the contributing zone of an aquifer?
The contributing zone of an aquifer includes all watersheds that feed runoff into rivers and streams that flow over the recharge zone. In the transition zone, geologic features such as faults and fractures present possible avenues for contaminants in surface water to reach the aquifer.
What fault zone is the Edwards Aquifer on?
Balcones Fault Zone
Summary. The Edwards (Balcones Fault Zone) Aquifer is a major aquifer in the southcentral part of the state. It consists primarily of partially dissolved limestone that creates a highly permeable aquifer.
Where is Edwards Aquifer recharge zone?
Located in the heart of south central Texas, the Edwards Aquifer is the natural water resource that supports approximately 2 million of us. It is part of a much larger system that spans approximately 8,800 square miles. The Edwards Aquifer Authority manages the San Antonio segment of the Balcones Fault Zone.
What region is Edwards Aquifer?
The San Antonio Segment of the Balcones Fault Zone Edwards Aquifer (Aquifer) in South-Central Texas is one of the most productive aquifers in the United States.
Where is the Edwards Aquifer recharge zone?
The Recharge Zone occurs along the Balcones Fault Zone where the Edwards Plateau drops steeply and meets the Gulf Coastal Plain . Here, highly fractured limestones are exposed at the Earth’s surface, which allow rain and streamflow to infiltrate directly into the aquifer.
What is the Edwards Aquifer recharge zone?
The recharge zone is a 1,250 square mile area where highly faulted and fractured Edwards limestones outcrop at the land surface, allowing large quantities of water to flow into the Aquifer.
What is the level of Edwards Aquifer?
The Aquifer is divided into three main zones: the contributing zone, the recharge zone, and the artesian zone. The contributing zone occurs on the Edwards Plateau , also called the Texas Hill Country. It is about 5,400 square miles, and elevations range between 1,000 and 2,300 feet above sea level.
What is level Edwards Aquifer?
SAN ANTONIO – Edwards Aquifer levels saw a sharp decline in the month of April and continue to fall after a long period of healthy numbers. As of Monday, the J-17 well of the Edwards Aquifer sat at 664.3 feet . The last time the level was this low came in September 2018.
