Abstract:
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.
摘要:
污染现场管理是一个多目标决策,一般涉及不同的因素,例如技术的性能,环境影响,成本,和社会影响力。在这项研究中,我们开发了一种基于可持续性评估的方法,用于确定污染场地风险管理方案的优先级。我们将补救可持续评估和再开发可持续评估整合在一个框架中,并允许指标的优化。该框架从站点管理类型的定义开始,然后调查场地特征,筛选指标,量化指标,选择评估模型,选择主选项,具有不确定性分析的评估,并确定首选方案。为了演示框架的实用性,结果在中国西南部的一个污染地点提出,用于两个风险管理决策,场地修复和场地重建。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。演示表明,必须注意对网站的适当描述,程序的原则,和决策标准。
