| Zusammenfassung |
| The essential processes and mechanisms of the transport of contaminants from
a river to a well field via a flood water retention area are presented. The
transport is conceptualized as a succession of three phases: (1) contaminant
entry into the retention area, (2) passage through the soil zone and (3)
transport with the groundwater flow. Depending on the conditions of a given
location and on the properties of the contaminants of interest, processes
within each transport phase may reduce the concentration of the contaminants
at the well field. For the Kastenwoert-Rappenwoert study area, the results
of the described processes are shown by chemical and ecotoxicological
analyses as well as by numerical modelling. Based on the results of the
analyses, it is predicted that some contaminants in the study area will be
completely detained along the transport path, while others will be
transported as far as the well field, although in significantly reduced
concentrations. |
