Aquifer Storage and Recovery (ASR)has become a major component innumerous water resource manage-ment initiatives in Florida and other areas around the world. Despite the reliance on this important management tool, there have been challenges in developing ASR in many areas because of a number of factors, mostly involving less-than-anticipated rates of water recovery and the manifestation of undesir-able water chemistry changes. In some cases, failure to achieve a suc-cessful ASR system has been the result of inappropriate storage zone selection. While several sources describe the general screening factors for selecting a storage zone, recent applications of a number of specific diagnos-tic tools and methods have significantly improved probability for developing a suc-cessful ASR system. This article discusses some of the most useful tools in ASR imple-mentation and describes how these tools were applied in selecting an ASR storage zon
