Contaminated site management is a multiple objective decision-making that generally involves different factors, such as performance of technology, environmental effects, cost, and social influence. In this study, we developed a sustainability assessment-based methodology for the prioritization of contaminated site risk management options. We integrate remediation sustainable assessment and redevelopment sustainable assessment in one framework and allow the optimization of indicators. The framework started with the definition of site management type, then investigating site characterization, screening indicators, quantifying of indicator, selecting assessment model, selecting primary options, assessment with uncertainty analysis, and determining of preferred options. To demonstrate the utility of the framework, results are presented in a contaminate site in southwest China for two risk management decisions, site remediation and site redevelopment. We used different approaches to evaluate the stability and robustness of assessment results, including Monte Carlo simulation, scenario analysis, and sensitivity analysis. The demonstration showed that attention has to be paid to the proper description of the site, the principles of the procedure, and the decision criteria.
污染场地管理是一个多目标决策过程，通常涉及不同的因素，如技术性能、环境影响、成本和社会影响。在本研究中，我们开发了一种基于可持续性评估的污染场地风险管理方案优先级排序方法。我们将修复可持续性评估和再开发可持续性评估整合到一个框架中，并允许对指标进行优化。该框架从场地管理类型的定义开始，然后调查场地特征描述、筛选指标、指标量化、评估模型选择、主要方案选择、不确定性分析评估和首选方案确定。为了展示该框架的实用性，我们以中国西南地区的一个污染场地为例，针对场地修复和再开发两个风险管理决策，展示了结果。我们使用不同的方法来评估评估结果的稳定性和稳健性，包括蒙特卡罗模拟、情景分析和敏感性分析。该实例表明，必须注意场地的正确描述、程序的原则和决策标准。
