Book excerpt: At least two distinct kinds of hydrogeochemical models have evolved historically for use in analyzing contaminant transport, but each has important limitations. One kind, focusing on organic contaminants, treats biodegradation reactions as parts of relatively simple kinetic reaction networks with no or limited coupling to aqueous and surface complexation and mineral dissolution/precipitation reactions. A second kind, evolving out of the speciation and reaction path codes, is capable of handling a comprehensive suite of multicomponent complexation (aqueous and surface) and mineral precipitation and dissolution reactions, but has not been able to treat reaction networks characterized by partial redox disequilibrium and multiple kinetic pathways. More recently, various investigators have begun to consider biodegradation reactions in the context of comprehensive equilibrium and kinetic reaction networks (e.g. Hunter et al. 1998, Mayer 1999). Here we explore two examples of multiple equilibrium and kinetic reaction pathways using the reactive transport code GIMRT98 (Steefel, in prep.): (1) a computational example involving the generation of acid mine drainage due to oxidation of pyrite, and (2) a computational/field example where the rates of chlorinated VOC degradation are linked to the rates of major redox processes occurring in organic-rich wetland sediments overlying a contaminated aerobic aquifer.

Available in PDF, EPUB and Kindle. Book excerpt: Mankind has manipulated the quantity and quality of soil water for millennia. Food production was massively increased through fertilization, irrigation and drainage. But malpractice also caused degradation of immense areas of once fertile land, rendering it totally unproductive for many generations. In populated areas, the pollutant load ever more often exceeds the soil’s capacity for buffering and retention, and large volumes of potable groundwater have been polluted or are threatened to be polluted in the foreseeable future. In the past decades, the role of soil water in climate patterns has been recognized but not yet fully understood. The soil-science community responded to this diversity of issues by developing numerical models to simulate the behavior of water and solutes in soils. These models helped improve our understanding of unsaturated-zone processes and develop sustainable land-management practices. Aimed at professional soil scientists, soil-water modelers, irrigation engineers etc., this book discusses our progress in soil-water modeling. Top scientists present case studies, overviews and analyses of strengths, weaknesses, opportunities and threats related to soil-water modeling. The contributions cover a wide range of spatial scales, and discuss fundamental aspects of unsaturated-zone modeling as well as issues related to the application of models to real-world problems.

This book was released on 2011-12-23 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geochemical modeling is an important tool in environmental studies, and in the areas of subsurface and surface hydrology, pedology, water resources management, mining geology, geothermal resources, hydrocarbon geology, and related areas dealing with the exploration and extraction of natural resources. The book fills a gap in the literature through its discussion of geochemical modeling, which simulates the chemical and physical processes affecting the distribution of chemical species in liquid, gas, and solid phases. Geochemical modeling applies to a diversity of subsurface environments, from the vadose zone close to the Earth’s surface, down to deep-seated geothermal reservoirs. This book provides the fundamental thermodynamic concepts of liquid-gas-solid phase systems. It introduces the principal types of geochemical models, such as speciation, reaction-path or forward, inverse- and reactive-transport models, together with examples of the most common codes and the best-practices for constructing geochemical models. The physical laws describing homogeneous and heterogeneous chemical reactions, their kinetics, and the transport of reactive solutes are presented. The partial differential or algebraic equations representing these laws, and the principal numerical methods that allow approximate solutions of these equations that can provide useful solutions to model different geochemical processes, are discussed in detail. Case studies applying geochemical models in different scientific areas and environmental settings, conclude the book. The book is addressed to students, teachers, other professionals, and to the institutions involved in water, geothermal and hydrocarbon resources, mining, and environmental management. The book should prove useful to undergraduate and graduate students, postgraduates, professional geologists and geophysicists, engineers, environmental scientists, soil scientists, hydrochemists, and others interested in water and geochemistry.

Available in PDF, EPUB and Kindle. Book excerpt: Hydrogeochemistry is of great application in reconstructing the previous groundwater circulation under ice sheets due to meltwater recharging the subsurface having a geochemical signature that could be discriminated from the other sources of water produced under warmer climates. Many hydrogeological factors could affect the geochemical composition of groundwater. These include the climate conditions, the lithology of the substrate and its hydraulic conductivity, the weathering, the length of the flow path, the penetration depth, the groundwater flow velocity and the residence time of groundwater.In recent years, hydrogeochemistry advances in analytical technology have allowed hydrogeochemical surveys to become a very powerful exploration technique. The new research works in this area are very broad and extensive. In this mini book, it is impossible to bring all of these novel techniques. The current Advances in Hydrogeochimistry Research book is limited to some diverse examples in different regions of the earth. As an introduction, chemical interaction between surface water and groundwater has been explained and discussed. A hydrogeochemical perspective of the wetland systems is then drawn. It has been combined with the biological remediation. Contaminant fate and transport in both groundwater and soil are also studied using different image analysis techniques. A case study in an Arab region of the world is comprehensively undertaken and the impact of groundwater pollution and quality on regional economics has been investigated. The concepts, classifications and applications of the groundwater modeling for solute transport simulation have been defined in the saturated porous media of the earth. An African analysis was done on assessing the microbiological quality of potable groundwater from the selected protected and unprotected wells in Zimbabwe. 36Cl for dating groundwater was contributed on the Guarani Aquifer System, located beneath the surface of Argentina, Brazil, Paraguay and Uruguay and is the second largest known aquifer system in the world and is attributed as an important source of freshwater. For semi-arid and arid zones of Iran, geospatial techniques in hydrogeochemistry have been used by intersecting the layers and statistical analysis. Then, a hydrochemical analysis of the bottled mineral waters has been comparatively studied. In another part of Africa, a semiarid part of North Eastern Nigeria, physicochemical characteristics of groundwater are widely determined. It has been also shown that the hydraulic fracking associated with the coalbed methane production has a great impact on water resources. Finally, various case studies have been done on the environmental state of freshwater, natural resources and mine waters in the some parts of Serbia, Spain and Central Asia. In addition, the implications on regional water resources management have been indicated.This book is intended primarily as a textbook at the graduate/research level and as a guide for field engineers, enabling them to remain current with scientific developments. As a simple prerequisite, the readers should have basic background knowledge in groundwater engineering and a general understanding of environmental and geological processes.

This book was released on 2016-07-20 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is the Earth's most precious resource. Until recent years, water was often overlooked as being overly abundant or available, but much has changed all over the world. As climate change, human encroachment on environmental areas, and deforestation become greater dangers, the study of groundwater has become more important than ever and is growing as one of the most important areas of science for the future of life on Earth. This three-volume set is the most comprehensive and up-to-date treatment of hydrogeochemistry that is available. The first volume lays the foundation of the composition, chemistry, and testing of groundwater, while volume two covers practical applications such as mass transfer and transport. Volume three, which completes the set, is an advanced study of the environmental analysis of groundwater and its implications for the future. This third volume focuses more deeply on the analysis of groundwater and the practical applications of these analyses, which are valuable to engineers and scientists in environmental science, groundwater remediation, petroleum engineering, geology, and hydrology. Whether as a textbook or a reference work, this volume is a must-have for any library on hydrogeochemistry.

This book was released on 2020-12-23 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past five decades, we have witnessed a tremendous evolution in water resource system management. Three characteristics of this evolution are of particular note: First, the application of the systems approach to complex water management problems has been established as one of the most important advances in the field of water resource management. Second, the past five decades have brought a remarkable transformation of attitude in the water resource management community towards environmental concerns and action to address these concerns. Third, applying the principles of sustainability to water resource decision-making requires major changes in the objectives on which decisions are based, and an understanding of the complicated inter-relationships between existing ecological, economic, and social factors. The Special Issue includes 15 contributions that offer insights into contemporary problems, approaches, and issues related to the management of complex water resources systems. It will be presumptuous to say that these 15 contributions characterize the success or failure of the systems approach to support water resources decision-making. However, these contributions offer interesting lessons from current experiences and highlight possible future work.
