To increase access to sustainable supplies of safe water for the poor, groundwater resources need to be exploited successfully, sustainably and economically on a much larger scale than they are at present. Unfortunately, techniques for finding and exploiting groundwater are not widely available. This book sets out to be a user-friendly guide to developing groundwater for rural water supplies. It is specifically designed and developed to meet the needs of rural water supply project staff in developing countries. It provides information on simple, effective techniques for siting wells and boreholes, assessing resource sustainability, constructing and testing the yield of boreholes and wells, and monitoring groundwater quality. The authors endeavour to set the technical aspects of rural water supply firmly in the relevant socio-economic context, so that guidance given is not in conflict with community aspects.

This book deals with the challenges for efficient groundwater management, with a focus on South Asia and India, providing a balanced presentation of theory and field practice using a multidisciplinary approach. Groundwater of South Asia is increasingly confronted with overuse and deteriorating quality and therefore requires urgent attention. Management of the stressed groundwater systems is an extremely complex proposition because of the intricate hydrogeological set-up of the region. Strategies for sustainable management must involve a combination of supply-side and demand-side measures depending on the regional setting and socio-economic situations. As a consequence, the challenges of efficient groundwater management require not only a clear understanding of the aquifer configuration, but also demand for the development of a comprehensive database of the groundwater occurrences and flow systems in each hydrogeological setting. In addition, drilling and well construction methods that are appropriate to different hydrogeological formations need to be implemented as well as real-time monitoring of the status of the groundwater use. Also corrective measures for groundwater that is threatened with depletion and quality deterioration need to be installed. Finally, the legal framework of groundwater needs to be rearticulated according to the common property aspect of groundwater. These challenges should revolve around effective groundwater governance by creating an atmosphere to support and empower community-based systems of decision-making and revisit the existing legal framework and groundwater management institutions by fostering community initiatives. This book is relevant for academics, professionals, administrators, policy makers, and economists concerned with various aspects of groundwater science and management.

Ground water resources are receiving global attention, as human population growth and development cause significant changes to the earth system. It plays a major role in ensuring livelihood security in many parts of South Asia and its contribution to poverty alleviation is substantial. The complex nature of ground water problems in the Indian Sub-continent requires a precise delineation of the ground water regimes in different hydro geological settings and socio-economic conditions and is a primary necessity for sustainable and equitable management. Strategies to respond to ground water over-exploitation and deteriorating water quality must be based on a new approach. Practical policies and various solution options urgently need to be formulated and implemented to prevent the development problems. There is pressing need to evolve workable methods and approaches based on modern scientific researches on ground water resources, as well as to build a social framework including community participation at all levels for a ground water development system. The community participation in water pumping policies, incentives of efficient use, affordability of low income users and other vulnerable groups, water awareness are prime factors for success of any ground water based water supply project.

This book presents a comprehensive, up-to-date review of technologies for cleaning up contaminants in groundwater and soil. It provides a special focus on three classes of contaminants that have proven very difficult to treat once released to the subsurface: metals, radionuclides, and dense nonaqueous-phase liquids such as chlorinated solvents. Groundwater and Soil Cleanup was commissioned by the Department of Energy (DOE) as part of its program to clean up contamination in the nuclear weapons production complex. In addition to a review of remediation technologies, the book describes new trends in regulation of contaminated sites and assesses DOE's program for developing new subsurface cleanup technologies.

Groundwater is Africa’s most precious natural resource, providing reliable water supplies for many people. Further development of groundwater resources is fundamental to increasing access to safe water across the continent to meet coverage targets and reduce poverty. There is also an increasing interest in the use of groundwater for irrigated agriculture as the climate becomes more variable. Sustainable development of the resource is not a trivial task and depends crucially on an understanding of the hydrogeology and people with the skills to make informed decisions on how groundwater can best be developed and managed in a sustainable fashion. Despite these obvious needs, however, little attention has been paid to the systematic gathering of information about groundwater resources in the past few decades, with the result that data are patchy, knowledge is limited and investment is poorly targeted. This book was written to start to bridge the knowledge gap. The 29 chapters are written by a combination of practitioners and researchers mainly from within Africa using experience from recent and ongoing projects. The chapters highlight the complexity and variety of issues surrounding the development and management of groundwater resources across Africa, and provide a snapshot of groundwater research and application in the early 21st century. Chapters range from strategic discussions of the role of groundwater in development and poverty reduction, to case studies on techniques used to develop groundwater, and modelling methods for managing groundwater systems.

The importance of groundwater to India's economy and development prospects should not be underestimated. The resource is of importance as a source of drinking water and food security for the 950 million inhabitants of India, supplies 80 percent of water for domestic use in rural areas and perhaps 50 percent of water for urban and industrial uses. Over the last three decades, the rapid expansion in use of groundwater primarily for irrigation has contributed significantly to agricultural and overall economic development in India. Groundwater irrigation potential, the number of wells, and the number of energized pump sets have grown exponentially since the early 1950s. Groundwater now supplies more than 50 percent of the irrigated area and, due to higher yields in groundwater-irrigated areas, is central to a significantly higher proportion of total agricultural output. In addition, in drought years, groundwater represents the primary reliable source of irrigation. This rapid development in groundwater, however, has had a price. In many arid and hard-rock zones, increases in overdraft areas and associated water-quality problems are emerging. Sustainability of the resource base is thus critical for meeting an array of basic needs -from health to economic development.
