Für eine sichere und nachhaltige Trinkwasserversorgung muss die Qualität von Trinkwasser wie auch von Rohwässern ständig mithilfe immer komplexerer Wasseranalysen überwacht werden. In dieser vollständig überarbeiteten und an die aktuelle Trinkwasserverordnung angepassten Neuauflage seines Klassikers bietet Walter Kölle anhand von zahlreichen Beispielanalysen einmal mehr einen umfassenden Überblick über wasserchemische Grundlagen, die Relevanz verschiedener Messgrößen für die unterschiedlichen Wassertypen, das Vorkommen von natürlichen und anthropogenen Wasserinhaltsstoffen, sowie praktische Hinweise zur Berechnung und Auswertung von Analysedaten. Die in Deutschland und in der EU gültigen Grenzwerte gemäß Trinkwasserverordnung und Europäischer Trinkwasserrichtlinie werden durchgehend berücksichtigt. Zahlreiche Parameter wurden neu aufgenommen, beispielsweise Arzneimittel, Bauchemikalien, Süßstoffe, Phthalate und Mikroplastik. Ein besonderes Augenmerk gilt der der Calcitsättigung und ihrer Bedeutung für die Trinkwassernutzung sowie ihrer Berechnung nach der neugefassten DIN-Norm. Auf der zugehörigen Webseite findet der Leser umfangreiches ergänzendes Bildmaterial u. a. zu den Reaktionspartnern des Wassers im Grundwasserleiter, zur Wasseraufbereitung, zu Biofilmen, Korrosionsprodukten und Asbest. Ein unverzichtbarer und in der Praxis bestens bewährter Leitfaden für jeden, der beruflich mit der Überwachung der Wasserqualität zu tun hat.

Die vorliegende Dissertation widmet sich der Entwicklung von verfahrenstechnischen Moeglichkeiten zur Erweiterung von Ultra-Low-Pressure Ultrafiltration (ULPUF) mit dem Ziel der Bereitstellung von arsenfreiem Trinkwasser in wirtschaftlich schwachen Regionen der Erde. Zur Arsenentfernung auf den WHO-Richtwert von 10 ?g/L wurde die Kombination der ULPUF mit der Adsorption an Tonerde (C-ULPUF) und der Elektrokoagulation (EC-ULPUF) untersucht.

Africa is highly vulnerable to the impacts of climate change. In particular shortage of fresh water is expected to be the dominant water problem for West and Northwest Africa of the 21th century. In order to solve present and projected future problems concerning fresh water supply, a highly interdisciplinary approach is used in the book. Strategies are offered for a sustainable and future-oriented water management. Based on different scenarios, a range of management options is suggested with the aid of Information Systems and Spatial Decision Support Systems for two river catchments in Northwest and West Africa: the wadi Drâa in south-eastern Morocco and the Ouémé basin in Benin. The selected catchments are representative in the sense: "what can be learnt from these catchments for other similar catchments?

PHREEQC version 3 is a computer program written in the C and C++ programming languages that is designed to perform a wide variety of aqueous geochemical calculations. PHREEQC implements several types of aqueous models: two ion-association aqueous models (the Lawrence Livermore National Laboratory model and WATEQ4F), a Pitzer specific-ion-interaction aqueous model, and the SIT (Specific ion Interaction Theory) aqueous model. Using any of these aqueous models, PHREEQC has capabilities for (1) speciation and saturation-index calculations; (2) batch-reaction and one-dimensional (1D) transport calculations with reversible and irreversible reactions, which include aqueous, mineral, gas, solid-solution, surface-complexation, and ion-exchange equilibria, and specified mole transfers of reactants, kinetically controlled reactions, mixing of solutions, and pressure and temperature changes; and (3) inverse modeling, which finds sets of mineral and gas mole transfers that account for differences in composition between waters within specified compositional uncertainty limits.

The first comprehensive guide to one of today's most innovative approaches to environmental contamination Natural attenuation is gaining increasing attention as a nonintrusive, cost-effective alternative to standard remediation techniques for environmental contamination. This landmark work presents the first in-depth examination of the theory, mechanisms, and application of natural attenuation. Written by four internationally recognized leaders in this approach, the book describes both biotic and abiotic natural attenuation processes, focusing on two of the environmental contaminants most frequently encountered in groundwater--fuels and chlorinated solvents. The authors draw on a wealth of combined experience to detail successful techniques for simulating natural attenuation processes and predicting their effectiveness in the field. They also show how natural attenuation works in the real world, using numerous examples and case studies from a wide range of leading-edge projects nationwide involving fuel hydrocarbons and chlorinated solvents. Finally, they discuss the evaluation and assessment of natural attenuation and explore the design of long-term monitoring programs. An indispensable reference for anyone working in environmental remediation, Natural Attenuation of Fuels and Chlorinated Solvents in the Subsurface is essential reading for scientists and engineers in a range of industries, as well as state and federal environmental regulators, and professors and graduate students in environmental or chemical engineering.

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.

Updated throughout with the latest data and findings, the Second Edition of Essentials of Geochemistry provides students with a solid understanding of the fundamentals of and approaches to modern geochemical analysis. The text uses a concepts of chemical equilibrium approach, which considers the reactions that occur as a result of changes in heat production and pressure within the Earth to introduce students to the basic geochemical principles. This text is for those who want a quantitative treatment that integrates the principles of thermodynamics, solution chemistry, and kinetics into the study of earth processes. This timely text contains numerous examples and problems sets which use SUPCRT92 to allow students to test their understanding of thermodynamic theory and maximize their comprehension of this prominent field. New sections introduce current “hot” topics such as global geochemical change with the short and long term carbon cycle, carbon isotopes and the Permo-Triassic extinction event, kinetics and the origin of life and the use of boron and nitrogen isotopes.
