Soil and Water Contamination, Second Edition gives a structured overview of transport and fate processes of environmental contaminants. Dealing with all topics essential for understanding and predicting contaminant patterns in soil, groundwater and surface water, it contributes to the formation of a solid basis for adequate soil and water pollution control and integrated catchment management. A unique feature of this work is that it does not treat water and soil pollution as independent processes, but as components of an integrated whole. The core of this geoscientific approach is divided into four parts: • Introduction to the basics of soil and water contamination, such as the fundamentals of environmental pollution and chemistry and the basic properties of soil, groundwater and surface water. • Source, role, and behaviour of substances in soil and water, treating natural and anthropogenic sources of nutrients, heavy metals, radionuclides and organic pollutants as well as emerging substances of concern, their physico-chemical characteristics, behaviour, and toxicity. • Transport and fate of substances in soil and water, focusing on processes of transport, exchange and transformations like advection, dispersion, adsorption kinetics and biochemical decay. Special attention is paid to the mathematical description and modelling of these processes. • Patterns of substances in soil and water, explaining spatial and temporal patterns of pollutants in soil, groundwater, and surface water, illustrated by recent case studies from fundamental and applied research. This comprehensive, successful textbook, now in its second edition, has been conscientiously updated and extended and includes many case studies, examples and exercises sections, providing undergraduate and graduate students in the Earth and Environmental Sciences with all the material necessary for the study of soil and water contamination. In addition, it can serve as a useful source of information for professionals.

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.

Les eaux souterraines constituent le réservoir le plus important d’eau douce au niveau mondial. Leur rôle pour l’industrie, l’agriculture, ainsi que dans le cycle de l'eau, en particulier pour la maintenance des zones humides et du débit des cours d’eau superficiels (essentiel durant les périodes de sécheresse), est également capital. La préservation et la sauvegarde de cette ressource est donc une nécessité (sur le plan qualitatif et quantitatif) qui concerne à la fois ses usages et sa valeur environnementale. La protection des eaux souterraines a été à l’origine de l’élaboration de nombreux instruments réglementaires européens au cours des trente dernières années. L'ouvrage en expose méthodiquement les justifications, les modes d’emploi et les conditions d’application. À cet effet, le lecteur trouvera : des informations détaillées sur le régime de protection des eaux souterraines mis en place par la législation européenne (directive cadre sur l’eau et sa directive « fille »), ainsi que les descriptions d’avancées scientifiques en soutien à diverses étapes techniques de cette loi européenne, une présentation complète du cadre législatif et scientifique, la description des étapes clés (caractérisation, surveillance, évaluation des risques, programmes d'actions) qui devront permettre d'atteindre le « bon état » des eaux souterraines tel qu'il est exigé par la directive cadre sur l'eau. Ouvrage de référence concernant la législation européenne sur les eaux souterraines, Protection des eaux souterraines s’adresse non seulement aux professionnels de l'eau (gestionnaires, législateurs, industriels) mais également aux chercheurs et au personnel académique. Il est également recommandé aux étudiants en écoles d’ingénieurs.
