Groundwater is sometimes called “the hidden asset” – awareness of its existence and its importance is not well known and as a consequence the measures which are required to protect and manage it in an environmental sustainable way are either not taken or are taken too late. Where pollution has occurred and measures are taken too late it may take decades, or longer, until the necessary restoration of quality is achieved. This comprehensive text presents in the following sections: Groundwater monitoring in the regulatory and international context Conceptual modelling and network design Groundwater pollutants and other pressures Groundwater quality standards and trend assessment Case studies for groundwater assessment and monitoring in the light of EU legislation Groundwater measurements Associating external stakeholders The editors have collected state-of-the-art information on groundwater quality assessment monitoring from the international community, providing further stimulation to the work of all parties involved in the challenges this area creates to ensure sound quality assessment of groundwater.

It is a well-organized, advanced, clearly written resource for all the professionals, scientists, graduate students, consultants, and water sector managers who deal with groundwater and who seek a comprehensive treatment of the subject of groundwater age.

Marine Geochemistry offers a fully comprehensive and integrated treatment of the chemistry of the oceans, their sediments and biota. The first edition of the book received strong critical acclaim and was described as ‘a standard text for years to come.’ This third edition of Marine Geochemistry has been written at a time when the role of the oceans in the Earth System is becoming increasingly apparent. Following the successful format adopted previously, this new edition treats the oceans as a unified entity, and addresses the question ‘how do the oceans work as a chemical system?’ To address this question, the text has been updated to cover recent advances in our understanding of topics such as the carbon chemistry of the oceans, nutrient cycling and its effect on marine chemistry, the acidification of sea water, and the role of the oceans in climate change. In addition, the importance of shelf seas in oceanic cycles has been re-evaluated in the light of new research. Marine Geochemistry offers both undergraduate and graduate students and research workers an integrated approach to one of the most important reservoirs in the Earth System.

Groundwater is a vital source of water throughout the world. As the number of groundwater investigations increase, it is important to understand how to develop comprehensive quantified conceptual models and appreciate the basis of analytical solutions or numerical methods of modelling groundwater flow. Groundwater Hydrology: Conceptual and Computational Models describes advances in both conceptual and numerical modelling. It gives insights into the interpretation of field information, the development of conceptual models, the use of computational models based on analytical and numerical techniques, the assessment of the adequacy of models, and the use of computational models for predictive purposes. It focuses on the study of groundwater flow problems and a thorough analysis of real practical field case studies. It is divided into three parts: * Part I deals with the basic principles, including a summary of mathematical descriptions of groundwater flow, recharge estimation using soil moisture balance techniques, and extensive studies of groundwater-surface water interactions. * Part II focuses on the concepts and methods of analysis for radial flow to boreholes including topics such as large diameter wells, multi-layered aquifer systems, aquitard storage and the prediction of long-term yield. * Part III examines regional groundwater flow including situations when vertical flows are important or transmissivities change with saturated depth. Suitable for practising engineers, hydrogeologists, researchers in groundwater and irrigation, mathematical modellers, groundwater scientists, and water resource specialists. Appropriate for upper level undergraduates and MSc students in Departments of Civil Engineering, Environmental Engineering, Earth Science and Physical Geography. It would also be useful for hydrologists, civil engineers, physical geographers, agricultural engineers, consultancy firms involved in water resource projects, and overseas development workers.

Groundwater is one of the Earth’s most precious resources. We use it for drinking, bathing, and many other purposes. Without clean water, humans would cease to exist. Unfortunately, because of ignorance or lack of caring, groundwater is often contaminated through industrialization, industry, construction or any number of other ways. It is the job of the environmental engineer to remediate the contaminated groundwater and make what has been tainted safe again.Selecting the proper remediation strategy and process is the key to moving forward, and, once this process has been selected, it must be executed properly, taking into consideration the costs, the type of contaminants that are involved, time frames, and many other factors. This volume provides a broad overview of the current and most widely applied remedial strategies. Instead of discussing these strategies in a generic way, the volume is organized by focusing on major contaminants that are of prime focus to industry and municipal water suppliers. The specific technologies that are applicable to the chemical contaminants discussed in different chapters are presented, but then cross-referenced to other chemical classes or contaminants that are also candidates for the technologies. The reader will also find extensive cost guidance in this volume to assist in developing preliminary cost estimates for capital equipment and operations & maintenance costs, which should be useful in screening strategies. The eight chapters cover all of the major various types of contaminants and their industrial applications, providing a valuable context to each scenario of contamination. This is the most thorough and up-to-date volume available on this important subject, and it is a must-have for any environmental engineer or scientist working in groundwater remediation.

Petroleum is not as easy to find as it used to be. In order to locate and develop reserves efficiently, it's vital that geologists and geophysicists understand the geological processes that affect a reservoir rock and the oil that is trapped within it. This book is about how and to what extent, these processes may be understood. The theme of the book is the characterization of fluids in sedimentary basins, understanding their interaction with each other and with rocks, and the application of this information to finding, developing and producing oil and gas. The first part of the book describes the techniques, and the second part relates real-life case histories covering a wide range of applications. Petroleum geology, particularly exploration, involves making the best of incomplete results. It is essentially an optimistic exercise. This book will remove some of the guesswork. Brings together the most important geochemical methods in a single volume. Authored by two well-respected researchers in the oil industry. Real-life, international case histories.

Magma Redox Geochemistry Magma Redox Geochemistry The redox state is one of the master variables behind the Earth’s forming processes, which at depth concern magma as the major transport agent. Understanding redox exchanges in magmas is pivotal for reconstructing the history and compositional make-up of our planet, for exploring its mineral resources, and for monitoring and forecasting volcanic activity. Magma Redox Geochemistry describes the multiple facets of redox reactions in the magmatic realm and presents experimental results, theoretical approaches, and unconventional and novel techniques. Volume highlights include: Redox state and oxygen fugacity: so close, so farRedox processes from Earth’s accretion to global geodynamicsRedox evolution from the magma source to volcanic emissionsRedox characterization of elements and their isotopes The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity.

New exploration tools and techniques for a breakthrough paradigm of regional groundwater occurrence Fresh water is undoubtedly our most precious resource aside from the air we breathe, and the only commodity whose cost has steadily risen over time. At the same time, our understanding of the origins, pathways, and recharge mechanisms of the earth's most valuable «economic» mineral-groundwater-remains in the nineteenth century. It is ironic that this scientific anachronism is contributing to a global shortage of available fresh water supplies while oil, gas, and mineral discoveries have proliferated, vastly increasing the world's energy, precious metals, and industrial mineral reserves. Modern Groundwater Exploration details applications and results of proven twenty-first- century technologies and geological concepts adapted from the oil, gas, and mineral exploration industries for evaluating, developing, and managing previously undiscovered, massive, sustainable groundwater resources. Unprecedented in both its scope and authority, this timely book presents: * A new groundwater paradigm, coined Megawatershed, which accurately and comprehensively describes the earth's natural complex groundwater systems * Innovative exploration, drilling, and testing technologies that make major new ground-water sources more locatable and cost-effective to produce than ever before * Actual case studies in which megawatershed methods have identified vast quantities of new water and brought new hope to previously arid and desperately water-short locales * Chapters by former OECD DAC chairman Alexander R. Love, geopolitical analyst Dr. Ewan Anderson, and former director of the Trinidad and Tobago Water Resources Agency Dr. Utam Maharaj on the tremendous global implications of the megawater-shed paradigm. These experts explore the many beneficial applications of megawater-shed development, from macroeconomics to development of small island developing state (SIDS), and from critical environmental issues to water conflict resolution and the potential for a second «green revolution» The world's need for clean, dependable water is more urgent-and addressable-than ever before. Let Modern Groundwater Exploration introduce you to the authors' revolutionary megawatershed paradigm, along with the latest concepts and technologies for accessing vast reservoirs of groundwater-still today's safest, cleanest, and most plentiful water resource.
