Abstract The potential for biodegrading of mono-, di- and trichlorobenzenes in a contaminated aquifer in Bitterfeld (Saxony-Anhalt) was tested both in the laboratory and using on-site column experiments. Under the prevailing anaerobic conditions, the reductive dechlorination of 1,4-dichlorobenzene (1,4-DCB) takes place very slowly. Under aerobic conditions the indigenous micro-organisms are able to mineralize monochlorobenzene (MCB) and 1,4-DCB. The degradation rates for the other two isomeric dichlorobenzenes and for 1,2,4-trichlorobenzene (1,2,4-TCB) under aerobic conditions are significantly lower. Indications were found that once the oxygen has been consumed, Fe(III) species can be used as alternative electron acceptors.
