This book presents a unique and up-to-date summary of what is known about groundwater on our planet, from a global perspective and in terms of area-specific factual information. Unlike most textbooks on groundwater, it does not deal with theoretical principles, but rather with the overall picture that emerges as a result of countless observations, studies and other activities related to groundwater in all parts of the world. The focus is on showing the role and geographical diversity of groundwater—a natural resource of great importance in daily life, but poorly understood by the general public and even by many water sector professionals. The book starts by analysing groundwater in the context of the hydrological cycle. Subsequently, groundwater systems as physical units, with their boundaries mainly defined by geological conditions, are reviewed. The next chapter looks at groundwater as a resource, paying attention, among others, to its quantity and quality, to the differentiation between renewable and non-renewable resources, and to the techniques for withdrawing groundwater. This is followed by a systematic documentation of the quantities of groundwater withdrawn and used around the world, and of the corresponding shares of groundwater in each of the main water use sectors. After that, steadily growing needs for groundwater management interventions are identified, resulting from local human activities and global change (including demography, economic development and climate change). Finally, groundwater resources management is addressed and real-life cases are described that illustrate actions taken and experiences with different issues in different parts of the world. The authors attempted to write this book in such a way that it is accessible to a wider readership than just groundwater professionals. It will also benefit non-groundwater specialists who work in groundwater-related fields (water managers, land use planners, environmentalists, agronomists, engineers, economists, lawyers, and journalists), by broadening their understanding of groundwater and making them aware of the huge variety of groundwater settings. Groundwater specialists will use the book as a convenient reference on the geographical diversity of groundwater. Part of the contents or interpretations offered may even be new to them or enhance their knowledge of some aspects. The many maps, tables, and references will save much time for those who would otherwise have to search elsewhere for basic information on the globe’s groundwater.

This collection of papers is a snapshot of modern hydrogeology in which highly technical methods and approaches sit side-by-side with overlapping legal, social, organisational, institutional and governance considerations. Groundwater is integral to many human and environmental systems. Indeed, there appears to be a growing realisation that some of the most pressing physical problems in the field of hydrogeology - over-abstraction, salinization or pollution - can only really be solved by taking a multi-disciplinary approach to the issues that takes all other related professions into account. Whilst a ‘technical’ solution may be readily deciphered, the larger challenge usually lies in the sustainably-funded and widely-accepted implementation of that measure. This book ranges from discussion and debate on the hot topic of hydraulic fracturing of wells or ‘fraccing’ for shale gas and its potential to disrupt groundwater systems, to the application of highly technical modelling procedures to help solve complex, real world problems. It is a window on the preoccupations of modern hydrogeologists and an insight into the way in which hydrogeological techniques and methods are being holistically adapted to address problems in the real world. This book is targeted at professional hydrogeologists, sociologists, experts in governance, law and policy as well as ecologists and other professionals that nowadays all sit alongside groundwater understanding. The book will also appeal to politicians, resource managers, regulators and others interested in sustainable water supply.

This book addresses groundwater governance, a subject internationally recognized as crucial and topical for enhancing and safeguarding the benefits of groundwater and groundwater-dependent ecosystems to humanity, while ensuring water and food security under global change. The multiple and complex dimensions of groundwater governance are captured in 28 chapters, written by a team of leading experts from different parts of the world and with a variety of relevant professional backgrounds. The book aims to describe the state-of-the-art and latest developments regarding each of the themes addressed, paying attention to the wide variation of conditions observed around the globe. The book consists of four parts. The first part sets the stage by defining groundwater governance, exploring its emergence and evolution, framing it through a socio-ecological lens and describing groundwater policy and planning approaches. The second part discusses selected key aspects of groundwater governance. The third part zooms in on the increasingly important linkages between groundwater and other resources or sectors, and between local groundwater systems and phenomena or actions at the international or even global level. The fourth part, finally, presents a number of interesting case studies that illustrate contemporary practice in groundwater governance. In one volume, this highly accessible text not only familiarizes water professionals, decision-makers and local stakeholders with groundwater governance, but also provides them with ideas and inspiration for improving groundwater governance in their own environment.

Your Guide to Effective Groundwater Management Groundwater Assessment, Modeling, and Management discusses a variety of groundwater problems and outlines the solutions needed to sustain surface and ground water resources on a global scale. Contributors from around the world lend their expertise and provide an international perspective on groundwater management. They address the management of groundwater resources and pollution, waste water treatment methods, and the impact of climate change on groundwater and water availability (specifically in arid and semi-arid regions such as India and Africa). Incorporating management with science and modeling, the book covers all areas of groundwater resource assessment, modeling, and management, and combines hands-on applications with relevant theory. For Water Resource Managers and Decision Makers The book describes techniques for the assessment of groundwater potential, pollution, prevention, and remedial measures, and includes a new approach for groundwater modeling based on connections (network theory). Approximately 30 case studies and six hypothetical studies are introduced reflecting a range of themes that include: groundwater basics and the derivation of groundwater flow equations, exploration and assessment, aquifer parameterization, augmentation of aquifer, water and environment, water and agriculture, the role of models and their application, and water management policies and issues. The book describes remote sensing (RS) applications, geographical information systems (GIS), and electrical resistivity methods to delineate groundwater potential zones. It also takes a look at: Inverse modeling (pilot-points method) Simulation optimization models Radionuclide migration studies through mass transport modeling Modeling for mapping groundwater potential Modeling for vertical 2-D and 3-D groundwater flow Groundwater Assessment, Modeling, and Management explores the management of water resources and the impact of climate change on groundwater.

Calcium and magnesium are abundant in groundwater, but the role of groundwater as the essential source of these important nutrients is very often neglected. Hydrogeochemical studies have focused mainly on the distribution and behaviour of constituents that cause deterioration of water quality, such as: nitrate, nitrite or iron and manganese. Therefore, most recent books and papers concentrate mainly on these constituents and only a small number of papers describe the results of groundwater studies on other important water components such as calcium or magnesium. Calcium and magnesium are of great importance to human wellbeing and inadequate intake of either nutrient can impair health. The main objective of this book is to present a selection of studies on calcium and magnesium in groundwater and to highlight their importance for human health. The chapters in this book are written by hydrogeologists and hydrochemists as well as medical doctors and include: methods of investigation of calcium and magnesium in groundwaters, distribution and behaviour of calcium and magnesium in different aquifers, calcium and magnesium in bottled mineral and spring waters, and the significance of calcium and magnesium in waters for human health.

"A persuasive look at why some U.S. cities have prospered in recent decades while others have declined."—Bloomberg Businessweek We’re used to thinking of the United States in opposing terms: red versus blue, haves versus have-nots. But today there are three Americas. At one extreme are the brain hubs—cities like San Francisco, Boston, and Durham—with workers who are among the most productive, creative, and best paid on the planet. At the other extreme are former manufacturing capitals, which are rapidly losing jobs and residents. The rest of America could go either way. For the past thirty years, the three Americas have been growing apart at an accelerating rate. This divergence is one the most important developments in the history of the United States and is reshaping the very fabric of our society, affecting all aspects of our lives, from health and education to family stability and political engagement. But the winners and losers aren’t necessarily who you’d expect. Enrico Moretti’s groundbreaking research shows that you don’t have to be a scientist or an engineer to thrive in one of the brain hubs. Carpenters, taxi-drivers, teachers, nurses, and other local service jobs are created at a ratio of five-to-one in the brain hubs, raising salaries and standard of living for all. Dealing with this split—supporting growth in the hubs while arresting the decline elsewhere—is the challenge of the century, and The New Geography of Jobs lights the way. "Moretti has written a clear and insightful account of the economic forces that are shaping America and its regions, and he rightly celebrates human capital and innovation as the fundamental sources of economic development."—Jonathan Rothwell, The Brookings Institution

Water scarcity is spreading and intensifying in many regions of the world, with dire consequences for local communities, economies, and freshwater ecosystems. Current approaches tend to rely on policies crafted at the state or national level, which on their own have proved insufficient to arrest water scarcity. To be durable and effective, water plans must be informed by the culture, economics, and varied needs of affected community members. International water expert Brian Richter argues that sustainable water sharing in the twenty-first century can only happen through open, democratic dialogue and local collective action. In Chasing Water, Richter tells a cohesive and complete story of water scarcity: where it is happening, what is causing it, and how it can be addressed. Through his engaging and nontechnical style, he strips away the complexities of water management to its bare essentials, providing information and practical examples that will empower community leaders, activists, and students to develop successful and long-lasting water programs. Chasing Water will provide local stakeholders with the tools and knowledge they need to take an active role in the watershed-based planning and implementation that are essential for water supplies to remain sustainable in perpetuity.

A young readers edition of the New York Times bestseller The Disappearing Spoon, chronicling the extraordinary stories behind one of the greatest scientific tools in existence: the periodic table. Why did Gandhi hate iodine (I, 53)? How did radium (Ra, 88) nearly ruin Marie Curie's reputation? And why did tellurium (Te, 52) lead to the most bizarre gold rush in history? The periodic table is a crowning scientific achievement, but it's also a treasure trove of adventure, greed, betrayal, and obsession. The fascinating tales in The Disappearing Spoon follow elements on the table as they play out their parts in human history, finance, mythology, conflict, the arts, medicine, and the lives of the (frequently) mad scientists who discovered them. Adapted for a middle grade audience, the young readers edition of The Disappearing Spoon offers the material in a simple, easy-to-follow format, with approximately 20 line drawings and sidebars throughout. Students, teachers, and burgeoning science buffs will love learning about the history behind the chemistry.
