Modelling of the reactive transport of organic pollutants in ground water; Modellierung des reaktiven Transports organischer Schadstoffe im Grundwasser

Abstract

The book describes reactive transport of organic pollutants in ground water and its quantitative monitoring by means of numerical reaction transport models. A brief introduction dealing with the importance of and hazards to ground water and opportunities for making use of ground water models is followed by a more detailed chapter on organic pollutants in ground water. Here the focus is on organochlorine compounds and mineral oil products. Described are propagation mechanisms for these substances in the ground and, especially, their degradability in ground water. A separate chapter is dedicated to possibilities for cleaning up polluted ground water aquifers. The most important decontamination techniques are presented, with special emphasis on in-situ processes with hydraulic components. Moreover, this chapter discusses the self-cleaning capability of aquifers and the benefits of the application of models to ground water cleanup. In the fourth chapter the individual components of reaction transport models are indicated. Here it is, inter alia, differences in the formulation of reaction models as to their complexity, and coupling between suspended matter transport and reaction processes that are dealt with. This chapter ends with a comprehensive survey of literature regarding the application of suspended matter transport models to real ground water accidents.  More>>

This chapter ends with a comprehensive survey of literature regarding the application of suspended matter transport models to real ground water accidents. Chapter 5 consists of a description of the capability and principle of function of the reaction transport model TBC (transport biochemism/chemism). This model is used in the two described applications to the reactive transport of organic pollutants in ground water. (orig.) [German] Inhalt des vorliegenden Buches ist die Darstellung des reaktiven Transports organischer Schadstoffe im Grundwasser und dessen quantitative Erfassung mithilfe numerischer Reaktions-Transportmodelle. Auf eine kurze Einleitung zur Bedeutung und Gefaehrdung von Grundwasser und zu den Einsatzmoeglichkeiten von Grundwassermodellen folgt ein ausfuehrlicheres Kapitel ueber organische Schadstoffe im Grundwasser. Dabei liegt der Schwerpunkt auf den chlorierten organischen Verbindungen und den Mineraloelprodukten. Dargestellt werden die Ausbreitungsmechanismen fuer diese Stoffe im Untergrund und vor allem deren Abbaubarkeit im Grundwasser. Ein eigenes Kapitel ist dann den Moeglichkeiten zur Reinigung belasteter Grundwasserleiter gewidmet. Die wichtigsten Sanierungsverfahren werden vorgestellt, wobei besonders die in situ Verfahren mit hydraulischen Komponenten hervorgehoben werden. Diskutiert wird in diesem Kapitel ausserdem die Selbstreinigungsfaehigkeit von Aquiferen und der Nutzen von Modellanwendungen bei der Grundwassersanierung. Im vierten Kapitel werden die einzelnen Komponenten von Reaktions-Transportmodellen aufgefuehrt. Dabei wird u.a. auf die unterschiedlichen Formulierungen von Reaktionsmodellen hinsichtlich ihrer Komplexitaet eingegangen und die Kopplung zwischen Stofftransport und Reaktionsprozessen erlaeutert. Am Ende dieses Kapitels steht ein umfangreicher Literaturueberblick zur Anwendung von Stofftransportmodellen auf konkrete Grundwasserschadensfaelle. Das fuenfte Kapitel besteht aus einer Beschreibung der Faehigkeiten und der Funktionsweise des Reaktions-Transportmodells TBC (Transport-Biochemie-Chemie). Dieses Modell wird in den beiden folgenden Anwendungsfaellen zum reaktiven Transport organischer Schadstoffe im Grundwasser eingesetzt. (orig.)}
