| Research Abstract |
The migration of hazardous substances and purification effects at soil and groundwater contaminated sites were simulated by numerical analysis. Health risk analyses were also conducted at the same sites. First, the transport processes of groundwater contamination by organoarsenic compounds was examined using a three-dimensional numerical simulation. Secondly, anew in-situ containment combined with groundwater pumping was proposed, and also its risk reduction effect was examined. Finally, in the case of groundwater contamination by volatile organochlorine compounds, the variability characteristics of biodegradation effect and health risk were estimated at in-situ bioremediation sites.
