지중환경 관리를 위한 부지개념모델 구축 및 개선

초록

A conceptual site model is used to support decision-making of response strategy development, determination, andimplementation within a risk-based contaminated site management system. It aims to provide base information of the relevantsite characteristics and surface/subsurface conditions in order to understand the contaminants of concern and the associatedrisk they pose to the receptors. This study delineated the technical details of conceptual site model development, and discussedthe possibility of applying it in domestic subsurface contamination management. Conceptual site models can be developed invarious formats such as tables, diagrams, flowcharts, and figures. Contaminated sites are managed for a long period of timefollowing the steps of investigation, remediation design, remediation, verification, and post-remedation management. Theconceptual site model can be enhanced in each stage of the contaminated site management based on the continuously updatedinformation on the site's subsurface environment. In the process of enhancement for conceptual site model, precision isgradually improved, and it can evolve from a conceptual and qualitative form to a more quantitatvive and three-dimensionalmodel. In soil pollution management, it is desirable to incorporate the conceptual site model into the soil scrutiny system tobetter assess the current status of the contaminated site and support follow-up investigation and management.
