Beschreibung:
The presented thesis deals with the investigation of contaminant mass fluxes, offers an improved analysis of integral pumping tests and presents a reactive transport model based on those contaminant mass fluxes to improve our knowledge about the biogeochemical processes acting in a heterogeneous aquifer undergoing remediation. The inherent heterogeneity of groundwater bodies poses a problem for their investigation and remediation. Accessibility is usually limited at contaminated sites leaving often only few groundwater wells for observation. It is common practice to interpolate those values for analysis, however, as presented here, if the contaminant plume is distributed heterogeneously in the subsurface this might lead to over- or underestimation of contaminant mass fluxes. This can be counteracted if Integral Pumping Tests (IPTs) are employed ...
