The central scientific question of the priority program was to improve the knowledge of geo-chemical processes in seepage and groundwater - with the specific aim to quantify the impact of human influences. From the very beginning the priority program was re-stricted to those questions that could be handled within the limited period of six years. Hence we concentrated on three groups of Natural organic substances, anthropogenic organic substances (i.e., PAK, BTEX, PCB) as well as metals, relevant to the environment.This volume has two slightly different First of all it represents the international conference "GeoProc2002", which took place in Bremen from March 4-7, 2002 - a meeting that was designed specifically to address the subject of geo-chemical processes in seepage and groundwater. Over six years the German Science Foundation (DFG) funded priority program 546 "Geochemical Processes with long-term effects in anthropogenically affected seepage and groundwater". The results of 6 years of research were presented at the GeoProc2002 conference, and therefore this book also represents the conclusion of this priority program.

As part of the Priority Programme 546 run by the Deutsche Forschungsgemeinschaft on the subject of "Geochemical processes with long-term effects in anthropogenically influenced drainage and ground water", a number of geoscientists, chemists, physicists, microbiologists, engineers and mathematicians all collaborated. This book describes the various ideas, concepts and conclusions that resulted and that were used to develop a model for the reactive transport of materials in drainage and ground water.

A summary of the latest research in this field. The topics comprise the sedimentological examination and physical properties of the sedimentary solid phase, pore water and pore water constituents, organic matter as the driving force of most microbiological processes, biotic and abiotic redox reactions, carbonates and stable isotopes as proxies for paleoclimate reconstruction, metal enrichments in ferromanganese nodules and crusts as well as in hot vents and cold seeps on the seafloor. The current model conceptions lead to the development of different types of computer models, allowing the global mass exchanges between oceans and sediments to be balanced.
