STEM & School Education

At the EAA, our education program goal is to engage and inform eager, young minds about the Edwards Aquifer and the issues affecting it as our region’s primary water resource. Our presentations are targeted to specific audiences based on age and grade levels to encourage a common understanding and appreciation of our shared natural resource.

Aquifer Data

Water level data are critical to the EAA’s management of the extensive San Antonio Pool and the Uvalde Pool of the Edwards Aquifer. These data are measured around the clock using different devices to calculate the mean sea level in each monitoring well. The water level data are used for many purposes, including as criteria for determining when to impose groundwater withdrawal (drought) restrictions on aquifer users.understanding and appreciation of our shared natural resource.
