Abstract

When investigating large industrial site with very limited site historical information and monitoring data, there will be many challenges to determine the remediation cost and strategy. Here the author illustrates a methodology of risk assessment management for large industrial area. Based on proper conceptual model and professional judgement, a score card for each single site can be generated, including the risk scores for the source, path and receptors. Eventually the score results of the sites can be presented on the overall map through different colour. It is an efficient and direct way which can help the decision maker to tell the priority of allocating the resource for site investigation. The ranking of the site’s score will also show an expected cost level of the sites, which could remind the developer to apply more economical strategy at early planning stage.
