One of the greatest conundrums facing the arid western United States is the availability, use, and quality of groundwater. In large sections of the West, groundwater is the only dependable source of water for agricultural production and home consumption. Yet many of the aquifers are being depleted at a rate that will suck them dry within a century. Furthermore, dependence upon groundwater in many areas will only increase in the future. This dependence is already having serious consequences for small towns on the Great Plains. Faced with growing costs associated with deeper wells and the need for ever more advanced technology for extracting water, these towns find they lack the resources to maintain current agricultural practices. ø In this timely assessment of the West?s groundwater resources, the authors provide a detailed overview of groundwater management in the Western states. The authors present for each state the various management strategies, laws, and political realities that have made groundwater appropriation such a volatile subject. They also suggest possible difficulties that states and regions might face under current groundwater policies. By examining separate cases and viewing the West as a whole, the authors are able to identify not only the most pressing problems but also the most appropriate management techniques for protecting water supplies for future use.

Groundwater in the West covers the use, management, laws, and politics of groundwater in the West. The first chapter provides an overview of important groundwater management and policy issues. Each of the subsequent chapters presents a brief description of the water environment in each of the 19 states and the major groundwater regions in the state. These chapters provide a summary of ground water use and consumption by type of consumption, an examination of groundwater problems in the state, and a summary of groundwater law, administration, and regulations. The chapters conclude with a section summarizing groundwater politics (where appropriate) and an evaluation of future potential groundwater management problems. Hydrologists and people involved in groundwater use, control, and management will find the book invaluable.

This book presents a comprehensive analysis of the existing nature of India’s groundwater laws. In the backdrop of the gravity of groundwater crisis that threatens to engulf the country, the book examines the correlation between the imperfections in the law and water crisis and advocates a reform agenda to overhaul the legal framework. It accomplishes this objective by examining how some of the States and Union Territories regulate and manage groundwater through the legal instrumentality against the backdrop of the two conflicting paradigms: the “elitist” and the “egalitarian.” The book’s fundamental premise is that despite being an extraordinarily critical resource that supports India’s burgeoning population’s ever-increasing water demands, groundwater is abused and mismanaged. The key argument that it posits is that the elitist paradigm must give way to an egalitarian one where groundwater is treated as a common property resource. To place this message in perspective, the book’s introduction explains the dichotomy between the two paradigms in the context of groundwater. This sets the stage, after which the book is divided thematically into three parts. The first part deals with some of the general groundwater management concerns brought to the fore by the operation of the elitist paradigm. Since water is constitutionally a State subject, the second part analyses the groundwater legislations of different States and Union Territories set against their unique circumstances. As these laws do not dismantle the elitist paradigm that interlocks groundwater rights to land rights, the next part articulates the legal reform agenda where a case is made to re-engineer groundwater laws to reflect a more sustainable basis. The findings and arguments resonate with the situation in many developing countries around the world due to which the book is a valuable resource for researchers across disciplines studying this area, and also for policy makers, think tanks, and NGOs.

The aim of this book is to document for the first time the dimensions and requirements of effective integrated groundwater management (IGM). Groundwater management is a formidable challenge, one that remains one of humanity’s foremost priorities. It has become a largely non-renewable resource that is overexploited in many parts of the world. In the 21st century, the issue moves from how to simply obtain the water we need to how we manage it sustainably for future generations, future economies, and future ecosystems. The focus then becomes one of understanding the drivers and current state of the groundwater resource, and restoring equilibrium to at-risk aquifers. Many interrelated dimensions, however, come to bear when trying to manage groundwater effectively. An integrated approach to groundwater necessarily involves many factors beyond the aquifer itself, such as surface water, water use, water quality, and ecohydrology. Moreover, the science by itself can only define the fundamental bounds of what is possible; effective IGM must also engage the wider community of stakeholders to develop and support policy and other socioeconomic tools needed to realize effective IGM. In order to demonstrate IGM, this book covers theory and principles, embracing: 1) an overview of the dimensions and requirements of groundwater management from an international perspective; 2) the scale of groundwater issues internationally and its links with other sectors, principally energy and climate change; 3) groundwater governance with regard to principles, instruments and institutions available for IGM; 4) biophysical constraints and the capacity and role of hydroecological and hydrogeological science including water quality concerns; and 5) necessary tools including models, data infrastructures, decision support systems and the management of uncertainty. Examples of effective, and failed, IGM are given. Throughout, the importance of the socioeconomic context that connects all effective IGM is emphasized. Taken as a whole, this work relates the many facets of effective IGM, from the catchment to global perspective.

In 2007, the world's urban population surpassed the number of people living in rural areas and is still growing. The number of city dwellers who do not have access to piped water and rely on groundwater is also increasing. In many Asian cities, groundwater is not only the source of domestic water but also an important resource for industrial development, making better management of groundwater resources essential for sustainable development. Because groundwater is easier to access and costs less than water from piped systems, groundwater abstraction cannot be easily regulated. Policies for groundwater management adopted in Japan and other Asian countries are compared, and technologies for efficient use of groundwater are elucidated. Groundwater contamination is also a serious problem that exacerbates water scarcity in Asian cities. Case studies illustrate the cause and consequences of naturally occurring contaminants such as arsenic and fluoride, and groundwater contamination due to anthropogenic contaminants is described. Also discussed are technologies for treating contaminated groundwater to reduce the health risks of drinking contaminated groundwater.

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.

Groundwater is an indispensable resource in many parts of the world, where it supports domestic water supply, irrigated agriculture and industry. Its increased, and often intensive, use during the last half century has created problems and raised concerns regarding the potential depletion of local aquifers, water quality degradation and various geo
