One well detailed study but significantly different from standard guideline recommendations is available but no DT 50 value was reported or could be derived from this study.
One well detailed study (Wilson et al., 1986) but significantly
different from standard guideline recommendations is available. The
behaviour of commonly occurring contaminants was examined in microcosms
constructed with authentic aquifer material that receives municipal
landfill leachate and is known to support methanogenesis. All
manipulations were performed in anaerobic conditions and sterile
controls were performed by autoclaving at 121°C.
The disappearance of 1,1-dichloroethylene was not rapid and a lag
period of 16 weeks was required before significant degradation occurred
compared to autoclaved controls. After 40 weeks, there was a decrease of
60 % to 100 % of the concentration of 1,1-dichloroethylene compared with
autoclaved control. There was a decrease of 87 % to 100 % of the
concentration of 1,1-dichloroethylene compared with initial
