Abstract:

GEOTOX is a knowledge-based expert system designed to assist in the identification and classification of waste disposal sites. Existing methodologies such as formal or qualitative risk assessment and numerical modeling of contaminant transport are limited when dealing with incomplete or uncertain data, have difficulties to incorporate the evaluator's risk perceptions into the assessment and may require extensive amounts of data for a reliable application. This paper describes how GEOTOX can remove these limitations by utilizing plausible reasoning, and by relying upon its knowledge base to resolve problems of uncertainties, missing data, or effects of site-specific interactions. Using case-studies of waste sites the paper illustrates how GEOTOX is applied to various aspects of site investigation and assessment, and compares its performance with other methodologies.
