How much of the edwards aquifer is available for use? Although between 25 and 55 million acre-feet of water may be present in the Edwards aquifer, only a small portion of this water is practically or legally available for use.What is the transmissivity of the edwards aquifer? In the Edwards Aquifer some water may barely move, while in other areas water may travel miles (thousands of meters) in a single day. On average, the Edwards aquifer has been modeled with a transmissivity of about 100 ft2/day (9.29 m2/day). In the south, the Edwards Aquifer dips beneath the lowland plains of the gulf coast.Is the san antonio aquifer hydrogeologically separated from the edwards limestone? Groundwater pides exist in the west near Brackettville and in the east near Kyle, so the San Antonio segment of the Aquifer has long been though to be hydrogeologically separated from Edwards limestones on either side.What is the recharge zone for the san antonio aquifer? The aquifer's recharge zone, where surface water enters the aquifer, follows the Balcones Fault line, from Brackettville (roughly along U.S. Highway 90), through San Antonio, and north to Austin along but a few miles west of Interstate 35.
sands of agricultural and industrial users, the Edwards aquifer sustains outflow from several springs. Two major springs (discharging at rates averaging more than 100 cubic feet per second [ft3/s]) support recreational activities and businesses, provide surface water to sev eral thousand downstream users, and ensure the survival
