Abstract
One of recent serious environmental issues is soil and groundwater contamination caused by inappropriate storage, treatment and disposal of municipal and industrial waste materials. When a contaminated site is discovered, environmental risk to the surrounding area is immediately assessed and remediation measures have to be planned to minimize the expansion of the contamination. For performing this procedure effectively, it is necessary to systemize serial investigation processes including studies of contamination sources and underground expansion of hazardous materials, environmental risk assessment, and selection/recommendation of remediation methods. In this paper, a diagnosis system for effectively conducting the investigation processes is presented, and the role of computer simulation is focused as a tool for selection and evaluation of remediation alternatives in the system.
