Book Description
To understand hydrochemistry and to analyze natural as well as man-made impacts on aquatic systems, hydrogeochemical models have been used since the 1960’s and more frequently in recent times. Numerical groundwater flow, transport, and geochemical models are important tools besides classical deterministic and analytical approaches. Solving complex linear or non-linear systems of equations, commonly with hundreds of unknown parameters, is a routine task for a PC. Modeling hydrogeochemical processes requires a detailed and accurate water analysis, as well as thermodynamic and kinetic data as input. Thermodynamic data, such as complex formation constants and solubility-products, are often provided as databases within the respective programs. However, the description of surface-controlled reactions (sorption, cation exchange, surface complexation) and kinetically controlled reactions requires additional input data. Unlike groundwater flow and transport models, thermodynamic models, in principal, do not need any calibration. However, considering surface-controlled or kinetically controlled reaction models might be subject to calibration. Typical problems for the application of geochemical models are: • speciation • determination of saturation indices • adjustment of equilibria/disequilibria for minerals or gases • mixing of different waters • modeling the effects of temperature • stoichiometric reactions (e.g. titration) • reactions with solids, fluids, and gaseous phases (in open and closed systems) • sorption (cation exchange, surface complexation) • inverse modeling • kinetically controlled reactions • reactive transport Hydrogeochemical models depend on the quality of the chemical analysis, the boundary conditions presumed by the program, theoretical concepts (e.g.

Book Description
There remains a lack of understanding of environmental isotopes and their use; students and practitioners typically find the concepts of isotope concentrations and partitioning to be more complicated than for geochemistry. However, this need not be so, if the basics are presented together with geochemistry, using case studies and examples to make the point. This new book presents the basics of environmental isotopes and geochemistry together, with case studies and simple examples that build a real understanding of their use in natural and contaminated groundwater.

Book Description
The difficult struggle to protect our valuable ground-water resources necessarily involves scientists and engineers from many disciplines. To prevail in this effort, these practitioners—including microbiologists, hydrogeologists, geoscientists, and environmental engineers—must have a common understanding of essential ground-water quality issues and problems. That includes a basic grasp of how microorganisms and microbial processes affect the chemistry of ground water in both pristine and chemically stressed aquifer systems. Ground-Water Microbiology and Geochemistry marks the first attempt to bridge the historical lack of communication among these disciplines by detailing—in language that cuts across specialties—the impact of microorganisms and microbial processes on ground-water systems. To bring these diverse practitioners together, the book has been organized in three parts, with each section addressing the information needs of specific disciplines. The first six chapters of Ground-Water Microbiology and Geochemistry provide an overview of microbiology that’s geared to geoscientists who may lack formal training in the field. Here, the book systematically covers the kinds of microorganisms found in subsurface environments, focusing on their growth, metabolism, genetics, and ecology. The second part of the book, which covers four chapters, speaks both to geoscientists and to microbiologists. It offers a hydrologic perspective on how microbial processes affect groundwater geochemistry in pristine systems—an important topic for geochemists since most ground-water reservoirs have not been chemically affected by human activities, and naturally occurring microbial processes have major impacts on water quality. At the same time, Part Two introduces microbiologists to the different classes of ground-water systems, and gives an overview of techniques for sampling subsurface environments. In addition, microbiologists gain an understanding of biogeochemical cycling in ground-water systems—in coverage that’s unique to this book—and of the classic geochemical modeling techniques that are used to study microbial processes. The final three chapters of Ground-Water Microbiology and Geochemistry focus in on microbial processes in contaminated ground-water systems—a topic of central concern to environmental scientists. In this concluding section, microbiologists see how degradation processes depend upon the hydrologic and geochemical environments within which they operate. Having achieved a basic knowledge of microbiological and biochemical concepts from the earlier chapters, geoscientists are fully prepared for this treatment of microbial acclimation and the biodegradation of petroleum hydrocarbons and halogenated compounds. Ground-Water Microbiology and Geochemistry is as graphically impressive as it is far reaching. High-quality, computer-generated illustrations, of particular appeal to visually oriented geoscientists, can be found throughout the book. Equally important is the book’s unusually comprehensive bibliography, which, like the text itself, spans the relevant science and engineering disciplines. The importance of Ground-Water Microbiology and Geochemistry to geoscientists, hydrologists, and environmental scientists has been amply documented. The book should also be required reading for water planners and lawyers involved in environmental issues. It will also serve as a compelling text in upper undergraduate and graduate courses in ground-water chemistry.

Book Description
In Europe, ca. 1900 "mineral water" brandsare officially registered and bottled for drinking. Bottled waters isgroundwater and is in large parts of the continent rapidly developing into themain supply of drinking water for the general population.This book is the first state of the art overview of the chemistry ofgroundwaters from 40 European countries from Portugal to Russia, measured on1785 bottled water samples, equivalent to 1189 distinct bottled water brandsfrom 1247 wells in 884 locations plus an additional 500 tap water samplesacquired in 2008 by the network of EuroGeoSurveys experts all across Europe.In contrast to previously available compilations, all chemical data (containedon the enclosed CD) were measured in a single laboratory, under strict qualitycontrol with high internal and external reproducibility, affording a singlehigh quality, internally consistent dataset. More than 70 parameters weredetermined on every sample using state of the art analytical techniques withultra low detection limits (ICPMS, ICPOES, IC) at a single hydrochemical labfacility. Because of the wide geographical distributionof the water sources across 40 European countries, the bottled mineral,drinking and tap waters characterized herein may be used for obtaining a firstestimate of "ground- water geochemistry" at the scale of the EuropeanContinent, previously unavailable in this completeness, quality and coverage.The data published here allow for the first time to present a comprehensiveinternally consistent, overview of the natural distribution and variation ofthe determined chemical elements and additional state parameters of groundwaterat the European scale. Most elements show a very widerange, usually 3 to 4 but up to 7 orders of magnitude, of natural variation of their concentration. Data are interpreted in terms of their origin, considering hydrochemical parameters, such as the influence of soil, vegetation cover and mixing with deep waters, as well as other factors (bottling effects, leaching from bottles). A chapter is devoted to comparing the results from the bottled waters with those of European tap waters and previously published datasets. The authors also provide an overview of the legal framework, that any bottled water sold in the European Union must comply with. It provides a comprehensive compilation of current drinking water action levels in European countries, limiting values of the European Drinking/Mineral/Natural Mineral Water directives (1998/83/EC, 2003/40/EC, 2009/54/EC) and legislation in effect in 26 individual European Countries, and for comparison those of the FAO and in effect in the US (EPA, maximum contaminant levels [MCA]). The accompanying CD contains the extensive data sets, sample data (of 1189 different brands) and two previously published European water chemistry data sets.
