Decision Support Model to Optimize Site Characterization Activities Taken inCompliance with the Comprehensive Environmental Response Compensation and Liability Act

摘要

One of the most frequently cited reasons for the slow and costly progress ofSuperfund cleanups is the remedial investigation and feasibility study process (RI/FS). This research program developed decision support models to help decision makers choose between the feasible alternatives at five different decision points during site characterization activities. The models make recommendations on how to deal with any particular chemical based on the risk posed by that chemical. The models assume that the value of characterizing the site further is a reduction in the uncertainty associated with the chemical concentrations in the contaminated media and a reduction in the probability of errors occurring during and after remedy selection. The models developed in this research were verified and validated using data from a fully characterized hazardous waste site. The site evaluated was the POL Storage Area in operable unit two at Wright-Patterson AEB, Ohio. 1.
