... . Eastern states have also moved toward planning programs to address demands related to scarce water resources due to periodic droughts, increasing populations, changing land use, and the links between water use and environmental protection (Virginia Department of Environmental Quality, 2001)

... Because of the shortcomings often associated with storage in aboveground reservoirs–including evaporative losses, land consumption, and ecological impacts–there is increased interest in storing recoverable water underground as part of an overall water management plan. Storing surface water underground seems counterintuitive to many people, who consider this a "waste" because the water may move away from the recharge area and not raise the water table at all.

... The committee has described the operation of vadose zone wells in the report, but has found few successful systems to evaluate for physical, water quality, and institutional factors. The term "storage" also implies that the manager of the project intends to recover the water for a particular use -- as opposed to systems where the intent of the recharge is primarily to prevent land subsidence, control saltwater intrusion or movement of contaminant plumes, or generally raise groundwater levels.

... , while the Southern Nevada Water Authority currently has the largest ASR wellfield intended primarily for potable water supply, with more than 50 wells. At the other end of the spectrum, many small coastal towns along the Atlantic recharge water seasonally in small, one-well ASR systems to limit seawater intrusion and store water for the summer tourist season (AWWA, 2002)

... The Orange County Water District is currently constructing the largest indirect potable reuse facility in the world, which will provide 88 million m3 of highly treated recycled water per year for recharge using both wells and surface spreading. Other projects to store water underground are in operation or in development for many areas of the Southwest, including the rapidly growing communities of Las Vegas and Phoenix.

... Some states have developed formal procedures for review of project permit applications to involve various water quantity and quality regulatory agencies, as both state and federal agencies to streamline the regulatory and permitting process and define agency roles. Still, ensuring that management of MUS systems is performed in a balanced approach that addresses water use, groundwater protection, and drinking water regulatory concerns can be a challenge.

... provide a scientific basis for monitoring plans to track performance of operational systems and to gain knowledge for the design of future systems. The report also discusses financial and economic considerations within the context of BOX 1-3 Statement of Task Note: the original statement of task used the phrase "Sustainable Underground Storage" in lieu of "Managed Underground Storage." The proposed study will provide an overview of some of the research and education needs and priorities concerning managed underground storage technology and implementation.

... Chapter 6 has been included to address the management aspects of MUS systems, providing a review of the stages of an MUS project and examining some key operational issues including clogging, monitoring and indicators, public perception, and financial considerations. Finally, Chapter 7 presents MUS in an overall water resource systems context for the nation.
