BANK FILTRATION AND GROUNDWATER RECHARGE FOR TREATMENT OF POLLUTED SURFACE WATERS

Study of the fate of different bulk and trace organics at a bank filtration site at Lake Tegel in Berlin (Germany) and results of experiments on a long retention soil column system, to assess important factors of influence for the degradation of those organics. More than two years of monitoring for the bulk parameter dissolved organic carbon (DOC) proved that the redox conditions significantly influence the DOC degradation rates but not necessarily the residual concentration. LC-OCD measurements confirmed that the change in character is comparable for aerobic and anoxic/anaerobic infiltration.
