Part of: Symposium on Ground Water


An efficient approach has been developed for making rational and defensible decisions among a variety of 'options' (e.g., remedial actions, engineered barrier designs/operational controls, inventory limitations, site investigations and research) for mixed-waste disposal 'systems', which consist of multiple interacting sites (active, inactive and/or future) with multiple pathways. Such decisions are based on maximizing the satisfaction of identified objectives (including the reliability vis a vis specified criteria), explicitly considering tradeoffs among objectives as well as uncertainties in the consequences of any option.
