Workshop on September 21/22, 2023

Investigation methods for pollutant degradation in contaminated sites

The two-day workshop deals with the most important detection methods for the biological degradation of various groups of pollutants (CFC, BTEX, PAH, MKW, pesticides). The basics of isotope methods (component-specific isotope analysis CSIA, BACTRAPS), metabolite investigations, molecular biological methods (qPCR), fingerprinting are taught > (GC-MS) and laboratory microcosms. To this end, we carry out laboratory demonstrations and practical exercises. Together with engineering companies, we use concrete examples to discuss the consideration of pollutant degradation processes in various remediation strategies (remediation in connection with MNA, preparation and success control of in situ processes, aftercare of pump-and-treat), this year with a special focus on climate-related effects.
