Objective:
Our nation’s water management policies have resulted in increased evapotranspiration, storm flow and lower groundwater recharge. Rural application of enhanced aquifer recharge (EAR) allows for the greatest increase in water resource availability at a lower cost, while minimizing the risk to groundwater supplies. We will evaluate several methods of modification of rural basins to enhance recharge while monitoring the efficacy of each approach. Our hypothesis is that rural landscapes can be modified through low-cost approaches to enhance recharge such that the increased recharge can be quantified and easily implemented into a trading scheme to improve basin wide water management outcomes.
Approach:
A technical group has been assembled that is an extension of the Arbuckle-Simpson Technical Advisory Committee working the CAMARR Site. In partnership with the local stakeholders and the site owner (City of Ada, OK), we will employ microbiological, geochemical, sedimentological, groundwater gas monitoring, geophysical, and groundwater modeling tools to test the effectiveness and impacts of rural EAR structures to determine if these structures can be deployed as part of rural land management strategies to safely increase groundwater supplies in fractured and karstic aquifers.
Expected Results:
Our final product will be a Rural EAR technical guidance approach for safely developing rural EAR structures in fractured and karstic aquifers. The technical approach will be communicated locally through the Oka’ Institute at East Central University and nationally and internationally through peer reviewed journal articles and the National Ground Water Association University program.
