| Outline of Final Research Achievements |
Dynamics of hazardous substances and purification effects at soil and groundwater contaminated sites were simulated by numerical analysis. An ideal way of soil and groundwater remediation technology was also examined from a viewpoint of green remediation. First, transport processes of groundwater contamination by organoarsenic compounds and effects of pump and treat technology were evaluated using a three-dimensional numerical simulation. Secondly, in the case of groundwater contamination by volatile organic compounds, variability characteristics of biodegradation effect was estimated at an in-situ bioremediation site. In addition, in order to analyze environmental load of remediation technology, energy consumptions and CO2 emissions to in-situ bioremediation, pump and treat and a technique which combined both technologies were calculated. Reduction effects of the environmental load by solar power generation were also evaluated.
