In this activity, students look at the topography and cross-section of El Paso Texas and Edwards Aquifer in virtual reality, using historical data of the Edwards Aquifer that contains information on recharge, discharge and precipitation. From this data, conclusions can be made about future discharges of the aquifer.

This United States Geological Survey (USGS) fact sheet discusses in simple terms how water gets into the ground and becomes ground water. Using text and illustrations, this site explains what the water table is, what recharge water is, what an aquifer is, porosity and permeability, who uses ground water, how we get water out of the ground through wells, and the possibility of running out of water.
