Aquifer Storage and Recovery (ASR) is a water-storage technology gaining acceptance by water-resource planners and scientists worldwide. Essentially, ASR involves storage of available water through wells completed into aquifers, with subsequent retrieval from these same wells during dry periods. The U.S. Army Corps of Engineers plan for Everglades Restoration known as the Central and Southern Florida Project Comprehensive Review Study (Restudy) relies heavily on ASR technology. In fact, the Restudy assumes over 1.6 billion gallons per day of water stored via ASR wells. As you can see by the magnitude of this number, the scale of ASR proposed in the Restudy is unprecedented. Recovery of water stored in ASR wells could provide great benefits to environmental, agricultural, and urban users. The following graphics are intended to acquaint the reader with the ASR technology, present the uncertainties of ASR implementation at this scale, and outline a plan to address these uncertainties.
Many challenges face water-resource planners and scientists with respect to the ASR technology as proposed in the Restudy. A phased approach to ASR implementation is proposed to address technical and regulatory concerns. A wide variety of hydrogeologic, hydrologic, and hydrochemical questions must be resolved prior to development of a truly regional ASR infrastructure. It is clear that the proposed ASR pilot facilities -- and the science necessary to evaluate the data from these facilities -- will be crucial to evaluate the feasibility and effectiveness of ASR as a regional water-storage option.
