In this study, a decision-support system was developed for providing environmental managers with an integrated way for concisely analyzing and visualizing the subsurface contamination problem as well as a means for evaluating alternative remediation technologies. It integrated contaminant-transport modeling, risk assessment, and remediation-system design within a general framework. The developed system was applied to a site in western Canada that is contaminated by petroleum products. A three-dimensional multiphase multicomponent model was established, which provided a basis for further risk assessment. Several approaches based on different environmental guidelines were used to analyze risks due to the site contamination. The results suggested the urgency of taking remediation actions. Six remedial alternatives for cleaning up the site were recommended. Decisions could then be made based on a series of analyses and comparisons among the given alternatives.
在本研究中，开发了一个决策支持系统，为环境管理人员提供一种综合方法，以便简洁地分析和可视化地下污染问题，并提供一种评估替代修复技术的手段。它在一个通用框架内集成了污染物迁移建模、风险评估和修复系统设计。所开发的系统应用于加拿大西部一个受石油产品污染的场地。建立了一个三维多相多组分模型，为进一步的风险评估提供了基础。采用了几种基于不同环境准则的方法来分析场地污染造成的风险。结果表明采取修复行动的紧迫性。推荐了六种清理该场地的修复替代方案。然后可以基于对给定替代方案的一系列分析和比较做出决策。
