Using an Integrated Approach to Investigate Natural Biodegradation of Coal-Tar Compounds in a Deep Groundwater Aquifer Under Anaerobic Conditions(Abstract)

摘要

The natural degradation of coal-tar compounds under anaerobic conditions in a deep aquifer downgradient of a former tar and asphalt plant in Ringe, Funen, Denmark, was investigated by integrated plume characterization, including isotopic fractionation and specific degradation products, laboratory batch degradation tests for selected compounds and transport modeling. The overall scope of the project is to evaluate by line-of- evidence, whether natural degradation of the coal-tar compounds is sufficient to protect the local drinking water resource.
