| Project objectives:
The general goal of this proposal is the prevention and the riskbased
management of organic pollutants in the soil and groundwater
system with special focus on mobilization and immobilization
processes and related risks. In a first step the state-of-the-art in this
area will be identified, based on literature review focusing on the
main mechanisms and processes governing the transport and the
fate of organic contaminants. Of special importance is the question
how land use and climate change are influencing the natural attenuation
and mobilization processes. Based on the outcome of this
review process, innovative strategies will be elaborated on the basis
of additional research information and methodological knowledge,
thus contributing to the long-term risk-based management of organic
soil and ground water pollution. Results will be formulated in
such a way that they are applicable by end-users.
Special focus will be directed towards pollutant retention processes
by different soil constituents, looking at the strength of binding
forces and the long-term stability of such compounds. The question
involved is the definition of risks, which remain after the removal of
non-bound or less-bound pollutants. Moreover, the release of OMcolloids
loaded with pollutants is specifically judged under the aspect
of their contribution to organic pollutant mobilization and leaching.
This includes the colloidal transport on long distances in the soil
and groundwater system and the spreading of pollutants caused by
these transport processes. Of special interest will be the time scale
and the risks caused by these fractions. Knowledge on how the
binding of pollutants to colloids interferes with natural attenuation
processes is still limited and is therefore subject of this investigation.
On this base, the limits of natural attenuation for mitigating risks will
The results of these investigations will be published in different
forms but with clear focus on end- users. M.Sc. and PhD. students will be invited to participate in this project.
The project has been started in November 2007 and will have a duration of 12 months. Further information will be uploaded as soon as available.
