ABSTRACT
The process of determining site remediation alternatives is usually comprehensive and most often time-consuming as well as expensive. Several computer-aided systems have been used to prompt users to determine applicable treatment technologies by the characteristics of site and contaminant (Penmetsa and Grenney, 1993). However, most of these computer systems have been developed for all types of wastes, and access the site and contaminant characteristics by complicated queries and models. For metal-contaminated sites, the computer decision-making process of remedial technology selection needs further study, since metal-contaminated soils are intractable and spatial-dependent (Benker, 1995). In general, detailed descriptions rather than principle classification of remedial techniques for metal-contaminated soil are necessary, and spatial attributes should also be taken into account.
