“…Baker, Deventer, Netherlands) to 2 mL. O 2 -consumption, CO 2 , N 2 , and N 2 O productions were determined by GC with thermo conductivity detector, NO 3 -, NO 2 -, SO 4 2-by ion chromatography, BTEX and the inherent tar oil compounds by MHE (multiple-headspace-extraction)-GC-MS as well as 15 EPA PAHs by RP-HPLC-FLD as described previously [20].…”

“…A heterogeneous contamination, consisting of aliphatic and aromatic hydrocarbons, heterocyclic aromatic compounds as well as phenols was detected at this site [18]. On the basis of groundwater chemical analyses and redox potential in the center of contamination sulfate reduction is the predominant redox condition [19,20]. The wells B 65, B 66, and B 67 are located in the plume near the source of contamination, the well B 85 is situated downstream the plume and not polluted.…”

“…Therefore, additional studies in closed systems and under known redox conditions are required to identify the degradation mechanisms. Laboratory (Hunt et al, 1997;Bjerg et al, 1999;Althoff et al, 2001) and in situ microcosms (Gillham et al, 1990a;Gillham et al, 1990b;Acton and Barker, 1992;Bjerg et al, 1996;Bjerg et al, 1999) have frequently been used to demonstrate biodegradation of contaminants by indigenous microorganisms under conditions closely resembling ambient. For example, in a laboratory biodegradation study comparing alkylbenzene biodegradation at two sites, the evaluation of degradation patterns in microcosms constructed with sediment and groundwater from several areas of the plume allowed for a reasonable comparison with field data throughout the plume length.…”

“…Conventional methods of evaluating biodegradation in ground water comprise either static microcosm or flow-through column studies in the laboratory (Althoff et al, 2001), field-based estimates with reactive well tests (Istok et al, 1997;Istok et al, 2001;Haggerty et al, 1998), or field data analysis especially via numerical modelling (Brauner and Widdowson, 2001;Thornton et al, 2001;Huling et al, 2002;Prommer et al, 2002., Bockelmann et al, 2003.…”
