A single framework integrating
risk assessment and decision analysis methods for evaluating, ranking and selecting
preferred remediation alternatives at a contaminated site was developed and
demonstrated. The methodology used relies on stakeholder inputs throughout the
entire process and employs those inputs to combine the results of multiple risk
assessments to arrive at a total impact for each remediation alternative. The
total impact values allow the ranking of the alternatives, which in turn, serves
as the basis for deliberations among the stakeholders in order to identify the
preferred alternative. Six major risk or impact categories were considered in
the evaluation of the alternatives: human health and safety, environmental protection,
life cycle cost, socio-economics, cultural, archeological and historical resources,
and programmatic assumptions.
