摘要:The development of a conceptual site model (CSM) is an invaluable tool used for assessing and planning remedial actions at a contaminated site. The CSM incorporates site-specific, hydrogeologic and geochemical information to identify contaminants of concern, sources of pollution, environmental pathways and retardation mechanisms, and points of exposure. The model is dynamic and continually revised as new information is obtained during the course of investigation. A ground water contamination case study is examined to illustrate the development and application of a CSM. The site is a metal plating facility that has contaminated the ground water with chromium. The CSM was incorporated into a 3-D fate and transport model. The Heavy Metal model, HM-3D, was used to simulate the fate and transport of chromium at the site and evaluate pump-and-treat remediation scenarios.
