Groundwater is an increasingly important resource to human populations around the world, and the study and protection of groundwater is an essential part of hydrogeology - the subset of hydrology that concentrates on the subsurface. Environmental isotopes, naturally occurring nuclides in water and solutes, have become fundamental tools for tracing the recharge, history, and contamination of groundwater.

Handbook of Environmental Isotope Geochemistry, Volume 1: The Terrestrial Environment, A focuses on isotope hydrology and aqueous geochemistry, as well as an overview of carbon, sulfur, and nitrogen isotopes in terrestrial systems. The selection first elaborates on the isotopes of hydrogen and oxygen in precipitation, carbon-14 in hydrogeological studies, and environmental isotopes in groundwater hydrology. Concerns cover groundwater dating, mechanism of salinization, groundwater recharge, models of the isotope fractionation during evaporation and condensation of water in the atmosphere, and stable isotope distribution in atmospheric waters. The book then examines environmental isotopes in ice and snow, isotopic evidence on environments of geothermal systems, and sulfur and oxygen isotopes in aqueous sulfur compounds. Discussions focus on geochemistry and isotope distribution of aqueous sulfur compounds, isotopic dating of geothermal waters, origin of chemical constituents, geothermometry, isotope distribution during the reduction of a temperate snow cover, and snow and ice isotope hydrology. The manuscript explores environmental isotopes as environmental and climatological indicators, sulfur isotopes in the environment, nitrogen-15 in the natural environment, and the isotopic composition of reduced organic carbon. The selection is a valuable reference for researchers interested in isotope geochemistry.

Enhanced analytical capabilities and separation techniques, improved detection limits, and accessibility of instrumentation have led to massive strides in the use of isotopes to assess microbial processes in surface and subsurface sediments. Considering the rapid growth of research and commercial interest in stable isotope and radioisotope applications for contaminant hydrology and microbial ecology, an up-to-date overview of the field is long overdue. Environmental Isotopes in Biodegradation and Bioremediation comprehensively covers established and emerging isotope methods for environmental applications, focusing on biodegradation and bioremediation. This book is an invaluable tool for researchers, practitioners, and regulators who require an extensive understanding of the application of isotope methods to natural compounds and environmental contaminants. It addresses questions including: What amount of a compound comes from anthropogenic release? Do the chemicals involved undergo degradation in the environment? Do they persist and accumulate? This book is divided into four sections: Isotope Fundamentals covers important background and theoretical information needed to understand later chapters Isotopes and Microbial Processes discusses the application of isotopes to different environmental redox conditions that dictate the predominant microbial processes that will occur Isotopes in Field Applications describes the transformation of anthropogenic pollutants and the application of isotope tools to field sites Isotope Emerging Areas addresses the use of compounds labeled with stable isotopes, including stable isotope probing and the use of radiocarbon at natural abundance and novel stable isotopes This reference details how isotope tools can be used to gain insight into the origin and fate of natural compounds and contaminants in the environment. Integrating theoretical and practical knowledge, the authors examine the principles of isotope tools and then present an extensive overview of key environmental processes that can be investigated with isotope methods. They also discuss analytical and data evaluation procedures, addressing established and emerging applications. To illustrate concepts and methodology, the authors use a wide range of case studies and recent field and laboratory research from various disciplines currently employing these methods. This book is a valuable tool for expanding the application of both stable isotopes and radioisotopes into untapped areas.

Hydrogeology: Principles and Practice provides a comprehensive introduction to the study of hydrogeology to enable the reader to appreciate the significance of groundwater in meeting current and future water resource challenges. This new edition has been thoroughly updated to reflect advances in the field since 2004. The book presents a systematic approach to understanding groundwater. Earlier chapters explain the fundamental physical and chemical principles of hydrogeology, and later chapters feature groundwater investigation techniques in the context of catchment processes, as well as chapters on groundwater quality and contaminant hydrogeology. Unique features of the book are chapters on the applications of environmental isotopes and noble gases in the interpretation of aquifer evolution, and on regional characteristics such as topography, compaction and variable fluid density in the explanation of geological processes affecting past, present and future groundwater flow regimes. The last chapter discusses groundwater resources and environmental management, and examines the role of groundwater in integrated river basin management, including an assessment of possible adaptation responses to the impacts of climate change. Throughout the text, boxes and a set of colour plates drawn from the authors’ teaching and research experience are used to explain special topics and to illustrate international case studies ranging from transboundary aquifers and submarine groundwater discharge to the over-pressuring of groundwater in sedimentary basins. The appendices provide conversion tables and useful reference material, and include review questions and exercises, with answers, to help develop the reader’s knowledge and problem-solving skills in hydrogeology. This accessible textbook is essential reading for undergraduate and graduate students primarily in earth sciences, environmental sciences and physical geography with an interest in hydrogeology or groundwater science. The book will also find use among practitioners in hydrogeology, soil science, civil engineering and planning who are involved in environmental and resource protection issues requiring an understanding of groundwater.

Within the discipline of environmental sciences, the stable-isotope methodology is being increasingly used, especially in the study of the water cycle and of paleo-climatology. This book reviews the natural variability of stable isotopes in the hydrosphere, describing the physico-chemical basis of isotope fractionalism, and applying this knowledge to natural waters as they move through the hydrologic cycle from the ocean to the atmosphere, the biosphere and the lithosphere. It focuses on the processes at the surface-atmosphere and land-biosphere-atmosphere interfaces, since these are the sites of major changes in isotope composition. In response to the increasing awareness of our changing climate, a discussion on the global view of the changing water cycle, in the past and future, concludes up the presentation.

Regional Approaches to Water Pollution in the Environment integrates knowledge and experience on pollution problems related to industrial, agricultural and municipal activities and former military sites, with special emphasis on the Black Triangle: the region situated at the borders between North Bohemia, Polish Lower Silesia and South Saxony. Here, some five million inhabitants live in an area of brown coal basins having the highest emissions of sulphuric and nitrogen emission in the whole of Europe. The large-scale damage in this region is due to obsolete technology and insufficient equipment for monitoring emissions. Health effects are severe, and controlling the pollution can only be done at high cost. There is thus a need to exchange knowledge and experience on methods for evaluating the expected effects of measures and purification techniques to remedy ground and surface water pollution.

Numerous hydrological projects have been carried out using isotopic methods over the last two decades in the ESCWA region, which includes the Arabian Peninsula, the Arabian countries to the north, and Egypt. The large amount of data obtained from groundwater samples has been evaluated together with the hydrogeological, hydrochemical and water management data available for the area. Analyses of the stable isotopes of oxygen, hydrogen, and carbon in the groundwater samples, as well as the naturally occurring radioactive isotopes of hydrogen and carbon are used for the localization of groundwater recharge areas; determination and quantification of mixtures of groundwater from different sources; reconstruction of groundwater flow systems on regional and local scales; determination of the paleoclimatic effects on the geohydraulic conditions; determination of groundwater ages, i.e., residence times; and distinguishing between renewable and fossil groundwater resources. Extensive hydrological studies using isotopic methods have been conducted in the ESCWA region on the following aquifer systems and topics: isotopic composition of precipitation in Jordan and Syria; groundwater turnover in karst aquifers in the highlands of western Jordan, the mountains in western Syria and the West Bank; groundwater recharge from precipitation and surface water on the Damascus plain; origin and age of groundwater in the basalt aquifer system in Jordan and Syria; recently recharged freshwater lenses and fossil groundwater in Badiye and Hamad (steppe and desert regions in Syria and eastern Jordan and the adjacent areas in Iraq and Saudi Arabia); low of fossil groundwater and local, recently recharged groundwater in Paleogene carbonate aquifers in eastern Saudi Arabia, the Golf region, and southern Oman; groundwater recharge from flash floods in the aquifers in unconsolidated rock in wadis and coastal plains of the Arabian Peninsula; age and origin of groundwater in aquifers in consolidated rock in the mountains of Oman. The discussion of the hydrogeological significance of isotope data is supplemented by comments on the most important current hydrogeological problems in the ESCWA region that could be investigated using isotopic methods. These include problems of groundwater recharge, the provenance of groundwater, groundwater flow systems on regional and local scales, paleohydrological conditions, and groundwater quality, particularly contamination by human activities. All available publications on the isotope hydrology of the ESCWA region are listed in the bibliography, as well as basic publications on isotope hydrology in arid regions.

The principle of transferable groundwater rights is that by making water rights capable of being traded in the market, water resources can be used more sustainably and efficiently. Groundwater would achieve its economic value, by switching from the high volume-low value irrigation, which is prevalent with many farmers, particularly in South Asia, to low volume-high value urban supply or the growing of intensive horticultural or cash crops. This book discusses transferable groundwater rights in their broader context. It starts with a detailed description of the physical aspects of groundwater, which non-technical readers should find useful, followed by a discussion of legal and economic aspects. Water transfers and the international experiences in transferable groundwater rights are dealt with in detail in two subsequent chapters. A model is presented to guide those involved in water resources management and planning in their decision process to introduce transferable groundwater rights and water rights trading. The author concludes that transferable groundwater rights potentially offer a better alternative to land-based water rights systems. However, he casts serious doubt on whether groundwater rights trading on its own can achieve water resources sustainability, environmental protection and social equity. Government intervention seems to be almost always needed to assist the water rights market and take responsibility for any of its adverse consequences.
