has other version or edition 5440266 Intrinsic dechlorination of 1,2-dichloroethane at an industrial site
This research is performed at an industrial site located in the Rotterdam Harbor Area, the Netherlands. At this site a confined sulfate reducing aquifer is contaminated with 1,2-dichloroethane (DCA). The objective of this research is to investigate the potential of intrinsic (bio)degradation and down-stream biostimulation as effective risk reducing measures at this site. Close to the contaminant source, DCA is present at concentrations up to 500 mg per liter. From the possible intrinsic dechlorination products of DCA (i.e. 2-chloroethanol, vinylchloride, chloroethane and ethene), vinylchloride is occuring at relatively high concentrations (up to 2 mg/liter) and is probably formed abiotically. The type, rate and parameter dependency of intrinsic biotic and abiotic dechlorinating processes occurring in this aquifer are currently being investigated by analyzing groundwater concentration profiles of the dechlorination products and by performing laboratory column studies with sediment cores. The efficiency of natural attenuation and the need and possibilities for further risk reduction i.e. by stimulating bioconversion processes in down-stream parts of the contaminant plume will be discussed.
