Die quantitative Erfassung menschlicher Einflüsse auf die Qualität von Grund- und Sickerwasser war Thema eines sechs Jahre lang von der DFG geförderten Schwerpunktprogramms und stand im Mittelpunkt der internationalen Konferenz GeoProc 2002 (Bremen, März 2002). In diesem Band werden in erster Linie Konferenzbeiträge und Forschungsberichte vorgestellt, die sich mit dem Schicksal dreier Substanzgruppen im Bodenwasser beschäftigen (natürliche organische Verbindungen, anthropogene organische Substanzen wie PCBs und PAKs sowie umweltrelevante Metalle).
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 substances: 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 objectives: 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.
