Growing demands for water in many parts of the nation are fueling the search for new approaches to sustainable water management, including how best to store water. Society has historically relied on dams and reservoirs, but problems such as high evaporation rates and a lack of suitable land for dam construction are driving interest in the prospect of storing water underground. Managed underground storage should be considered a valuable tool in a water manager's portfolio, although it poses its own unique challenges that need to be addressed through research and regulatory measures.

The report gives conclusions and recommendations for managed underground storage in four specific areas: hydrogeological; water quality; legal, economic, and institutional; and operational. It provides an integrated assessment of technical and institutional issues, guidance to prevent development of poorly conceptualized systems, and a scientific basis for monitoring operational systems. The authors conclude that managed underground storage systems will be an important tool in the arsenal of water management strategies, and that the findings in the report will help make the tool more accessible and sustainable for water supply managers as future demands increase.

A large part of the global population lives in arid lands which have low rainfall and often lack the water required for sustainable population and economic growth. This book presents a comprehensive description of the hydrogeology and hydrologic processes at work in arid lands. It describes the techniques that can be used to assess and manage the water resources of these areas with an emphasis on groundwater resources, including recent advances in hydrologic evaluation and the differences between how aquifer systems behave in arid lands versus more humid areas. Water management techniques are described and summarized to show how a more comprehensive approach to water management is required in these areas, including the need to be aware of cultural sensitivities and conditions unique to many arid regions. The integration of existing resources with the addition of new water sources, such as desalination of brackish water and seawater, along with reusing treated wastewater, will be required to meet future water supply needs. Also, changing climatic conditions will force water management systems to be more robust so that future water supply demands can be met as droughts become more intense and rainfall events become more intense. A range of water management techniques are described and discussed in order to illustrate the methods for integrating these measures within the context of arid lands conditions.

REGIONAL WATER SECURITY Regional Water Security provides new research on policy innovations that promote the application of demand management and green infrastructure (GI) in managing water resources across regions sustainably. In particular, with regional water security around the world at risk from climatic and non-climatic challenges impacting water quantity and water quality, this book, in addition to providing examples of demand management and GI being implemented in various locations globally, contains in-depth case studies that illustrate how regions, of differing climates, lifestyles, and income levels, have implemented policy innovations that promote the application of demand management and GI to achieve regional water security for humans while protecting and restoring the natural environment. Regional Water Security will be of interest to regional water resource managers, town and regional planners, resource conservation managers, policymakers, international companies, and organizations as well as environmental NGOs, researchers, and graduate and undergraduate students.

Water Reclamation Technologies for Safe Managed Aquifer Recharge has been developed from the RECLAIM WATER project supported by the European Commission under Thematic Priority 'Global Change and Ecosystems' of the Sixth Framework Programme. Its strategic objective is to develop hazard mitigation technologies for water reclamation providing safe and cost effective routes for managed aquifer recharge. Different treatment applications in terms of behaviour of key microbial and chemical contaminants are assessed. Engineered as well as natural treatment trains are investigated to provide guidance for sustainable MAR schemes using alternative sources such as effluent and stormwater. The technologies considered are also well suited to the needs of developing countries, which have a growing need of supplementation of freshwater resources. A broad range of international full-scale case studies enables insights into long-term system behaviour, operational aspects, and fate of a comprehensive number of compounds and contaminants, especially organic micropollutants and bulk organics. Water Reclamation Technologies for Safe Managed Aquifer Recharge depicts advances in water reclamation technologies and aims to provide new process combinations to treat alternative water sources to appropriate water quality levels for sustainable aquifer recharge.

The book is an overview of the diversity of anthropogenic aquifer recharge (AAR) techniques that use aquifers to store and treat water. It focusses on the processes and the hydrogeological and geochemical factors that affect their performance. This book is written from an applied perspective with a focus of taking advantage of global historical experiences, both positive and negative, as a guide to future implementation. Most AAR techniques are now mature technologies in that they have been employed for some time, their scientific background is well understood, and their initial operational challenges and associated solutions have been identified. However, opportunities exist for improved implementation and some recently employed and potential future innovations are presented. AAR which includes managed aquifer recharge (MAR) is a very important area of water resources management and there is no recent books that specifically and comprehensively addresses the subject.

Riverbank filtration is a low cost, yet efficient water treatment technology. It has most potential to provide safe drinking water to large cities located along rivers or lakes. In particular, it is ideal for large population centres in developing countries, where the cost of building extensive treatment facilities is prohibitive. Water filtration can be successfully implemented using naturally occurring sand and gravel along the river/lake banks. The cost of water produced by this means is much lower than that of water treated in conventional treatment plants. Authored by a multi-disciplinary team of experts, this volume addresses the scientific basis of the filtration process, and also numerous topics of importance for the planning, technical realization, and security of such plants. Their application for the removal of relevant chemical pollutants and a variety of pathogens is analysed in detail.
