This paper summarizes discussion among the 7 authors who served on an expert panel at the Third Battelle International Conference on Remediation of Contaminated Sediments held in New Orleans, Louisiana, USA, in January 2005. In this article, the authors review how sediment management decisions are currently made and address the question of how management decisions should be made in the future. It is arguably the case that sediment remediation presents greater challenges and more complexity than traditional land-based clean-ups. Although understanding of these challenges and complexities has grown over the last 25 y, there has been, until recently, relatively little innovation in the approaches used to manage the environmental risks posed by contaminated sediments. New methods that facilitate a more rigorous analysis of the multiple criteria considered in decision making have been developed. These methods, collectively known as multicriteria decision analysis (MCDA), coupled with the use of comparative-risk assessment and cost/benefit analysis, are proposed as an effective, efficient, and credible foundation for evaluating remedy alternatives at contaminated sediment sites.
本文总结了2005年1月在美国路易斯安那州新奥尔良市举行的第三届巴特尔国际污染沉积物修复会议上担任专家小组的7位作者之间的讨论。在本文中，作者回顾了当前沉积物管理决策是如何做出的，并探讨了未来管理决策应如何制定的问题。可以说，沉积物修复比传统的陆地清理面临更大的挑战和更复杂的情况。尽管在过去25年里对这些挑战和复杂性的理解有所增加，但直到最近，用于管理污染沉积物所带来的环境风险的方法相对来说创新较少。已经开发出了有助于对决策中考虑的多个标准进行更严格分析的新方法。这些方法统称为多标准决策分析（MCDA），再结合使用比较风险评估和成本效益分析，被提议作为评估污染沉积物场地修复替代方案的有效、高效且可靠的基础。
