Enhanced Aquifer Recharge

Aquifer Storage and Recovery (ASR) has been studied and implemented at many locations around the nation. Enhanced Aquifer Recharge is a unique application of ASR, focused around a rural landscape management approach to enhance natural infiltration process and re-purpose storm flow to groundwater and baseflow enhancement.


The City of Ada is partnering with the Chickasaw Nation, Oka’ the Water Institute at East Central University and Oklahoma State University looking at EAR as a cost-effective way to preserve the city's water supply. 

Other cities have projects in place to treat water supply and return it to the ground for later use. A water treatment plant, installing pipe and other equipment for this kind of water reuse is too expensive for a small city like Ada. An alternative is E.A.R.  

The Robert S. Kerr Environmental Research Center has provided technical assistance and the city has installed small leaky pond structures connected to naturally occurring faults in the Arbuckle-Simpson Aquifer to capture rainstorm runoff. This runoff should go back into the aquifer to recharge and enhance streams and springs flow. 


The research partnership developed in this area addresses critical research needs for Oklahoma and the nation, as well as providing a unique opportunity for ECU undergraduate and graduate students to collaborate, through Oka’s research activities, with future employers and world-class scientists.
