A risk-based decision model is developed and applied in the remediation design of a contaminated aquifer in Greece. Due to limited information and data concerning the spatially-varying hydraulic conductivity parameter, decision making takes place under conditions of uncertainty. The decision analysis method is successfully combined with the stochastic optimization method to determine the optimal positioning and operation of the clean-up wells for each alternative decision strategy.The combined risk-based decision analysis and stochastic optimization methodology presented in this paper proves that this framework is an effective way of solving groundwater management problems under uncertainty. This is due to the combination of the main advantages of the two methodologies, the determination of globally optimal solutions offered by the stochastic optimization, and the inclusion of costs, benefits, and risks of failure into a single objective function offered by the decision analysis.
