Fields, J., T. Tandy, R. Neill, J. Groves, R. Ross, AND D. Beak. Preliminary Shallow Electrical Resistivity Imaging (ERI) at the Enhanced Aquifer Recharge (EAR) Site . Presented at Enhanced Aquifer Recharge Stakeholder Update, Ada, OK, June 09, 2021.
Impact/Purpose:
This presentation will update EPA staff, EPA policymakers, and external stakeholders of geophysical tools that can be used for the installation of groundwater monitoring wells and long-term management of EAR.
Description:
Enhanced Aquifer Recharge (EAR) is the process of enhancing the natural conveyance of water into the subsurface to augment water supplies. The potential impacts to groundwater quality and flow following the use of EAR is poorly understood and karst geology has a high potential for groundwater storage and flow. This presentation will examine the extent of the epikarst and potential for shallow flow in the study area. One goal of this research effort is to demonstrate the use of geophysical tools for understanding the movement of water in an EAR system in a karst environment. The presentation will share preliminary findings from the shallow geophysical investigation.
