The search for sustainable and cost-effective technologies to remediate deep groundwater systems and ensure that they are free of contamination is vital, as deeper aquifers are often used as sources of drinking water. One promising solution for cleaning up contaminated groundwater systems is phytoremediation.

Aquifers are geological formations that “are characterized by their ability to store and transmit water” (Charbeneau 2000). There are three basic types of aquifers: confined, unconfined, or semi-confined. Confined aquifers are aquifers that are confined above and below by relatively impermeable or impervious material, such as clay.

These aquifers are a critical source of water for Texas, supplying 55 percent of the 14.7 million acre-feet of water used in the state in 2020. About 75 percent of this water is used for irrigation, with irrigators withdrawing most of this water from the Ogallala Aquifer alone (74 percent of all groundwater used for irrigation, or 4.5 million ...Nonetheless, similar patterns observed in head levels associated with the shallow and deep aquifers suggest that these units are hydraulically connected (Smith et al., 2017).
