Communities in many parts of the world are facing increasing difficulties in obtaining asustainable, long-term supply of freshwater in the face of increasing populations and, perhaps,also global climate change. Aquifer storage and recovery (ASR) is increasingly being lookedupon to provide large volumes of storage to capture seasonally or intermittently available excesswater for later beneficial use. ASR is a proven technology, but its implementation has not beenfree of problems. ASR systems vary in their hydrologic value (i.e., the degree to which theyachieve useful storage) and, in some instances, have either not met expectations or have failedentirely. It is now clear that the hydrogeology of ASR systems, such as the effects of aquiferheterogeneity and water-rock interactions, are more complex than originally envisioned.Excessive regulatory requirements unnecessarily increase project costs and adversely impact theeconomic viability of projects. However, the advantages of ASR as a tool for water resourcesmanagement are still compelling. The challenge moving forward is to take advantage of thelessons learned from the recent explosive growth in ASR system construction and research inorder to improve upon all aspects of the implementation and regulation of ASR.
