An expert systems approach to evaluating mobility and degradation of organics in soil systems is compared to conventional programming techniques. An expert system has been developed in order to demonstrate the utility of applied artificial intelligence (AI) to aid in the assessment of the potential for groundwater contamination. The system incorporates expert knowledge coupled with a chemical transport/degradation model and supporting data bases. Organic constituents are ranked by means of a 'Confidence Adjusted Mobility and Degradation Index' (CAMDI). An evaluation of 12 polynuclear aromatic (PNA) compounds contained within a wood preserving waste that has been applied to a soil system is presented.
