    Tetrachloroethylene (PCE) and trichloroethylene (TCE) from a former dry cleanery have contaminated the groundwater in Oitti, Finland. The AOX-analyses of this and former studies suggest a DNAPL-source in the aquifer. The DNAPL is a continuous source of groundwater contamination. The aquifer was investigated for redox conditions. The objective of the study was to estimate if the groundwater conditions would be suitable for the reductive dehalogenation of PCE and TCE. Transformations of PCE were studied in anaerobic microcosms, which were fed with revised anaerobic mineral medium, PCE and either lactate, ethanol, glucose, H2 or their mixture as the electron donor. The control bottles were made without added electron donor or they were injected with NaN3 as killed controls. The bottles were incubated at 8 and 25°C. The results suggest reductive dechlorination of chlorinated ethylenes in contaminated groundwater in Oitti if a suitable electron donor is provided. Pilot-scale experimentations are being started to study the design criteria of in situ bioremediation.
