Where and to what extent should remediation measures be taken to achieve our cleanup goals? Which are the remediation technologies that promise to be the most cost-efficient at a megasite? Although at a relativly high abstraction level, CARO trys to answer these questions. CARO represents a methodology that supports the decision-making on remediation strategies at megasites, where complex distributions of pollutants in soil and groundwater often make it difficult to plan and design effective cleanup solutions. The proposed methodology is based on a system dynamic modeling approach, where the system is represented by a risk based source-pathway-receptor concept and the dynamics predominantly by a mass flux model. The “dynamics“ of the model are obviously also based on the performance of soil and groundwater source remediation technologies as well as groundwater plume management options and combinations of these. The flexibility of the model will make it possible to simulate numerous remediation technologies and management scenarios based on the availability of real data at the megasite, and in the absence of these, on evaluated performance data from the literature. The possibility to compare different management scenarios as well as the rapid comparison of profiles of effects (mass reduction) and costs and their development in time, will provide essential information that will help site managers identify the most cost-efficient remediation setup and at the same time reach the prefixed goals.

Further information will be provided soon.
