An Expert support model for ex situ soil remediation

This paper presents an expert support model recombining knowledge and experience obtained during ex situ soil remediation. To solve soil remediation problems, an inter-disciplinary approach is required. Responsibilities during the soil remediation process, however, are increasingly decentralised, which results in dispersed knowledge. The aim of this model is to optimise knowledge transfer among the various parties involved in contaminated site management. Structured Knowledge Engineering (SKE) has been used as a framework for model development. The model was applied to petrol pollution underneath a fuel station and to a complex PAH and CN pollution at a former gasworks site. The structured approach requires scrutinising all relevant data in order to answer the questions related to an ex situ soil remediation operation. Moreover, it clarifies the roles of the different disciplines involved in the process.
