Site contamination is a global concern because of the potential risks for human health and ecosystem quality. Every contaminated site has its own specific characteristics and the increased availability and efficiency of remediation techniques makes the choice of remediation alternative increasingly complicated. In this paper an attributional Life Cycle Assessment (LCA) of the secondary environmental impacts of a site remediation is performed and its results are monetized using two different monetization techniques, namely Stepwise 2006 and Ecovalue 08. Secondly, we perform a social Cost-Benefit Analysis (CBA) on the same case study using the same data sources. The case study used in this paper entails the soil and groundwater remediation of a tar, poly-aromatic hydrocarbons (PAH) and cyanide contamination of a school ground by a former gas plant. The remediation alternative chosen in this case study is excavation with off-site thermal treatment of the contaminated soil. The outcome of the social CBA, stating that the remediation project is socially beneficial in the long term, is critically compared to the outcome of the different LCA monetization methods. This comparison indicates that monetized LCA is a good complement to social CBA when it comes to the assessment of secondary environmental impacts. Combining the two methods provides decision makers with a more extensive and detailed assessment of the soil remediation project.

由于对人类健康和生态系统质量的潜在风险，场地污染已成为全球关注的问题。每个受污染的站点都有其自己的特定特征，补救技术的可用性和效率不断提高，使得补救替代方案的选择变得越来越复杂。本文对场地修复的次级环境影响进行了生命周期评估（LCA），并使用两种不同的货币化技术（Stepwise 2006和Ecovalue 08）将其结果货币化。其次，我们进行了社会成本效益分析（CBA）使用相同的数据源进行相同的案例研究。本文中使用的案例研究涉及对土壤和地下水的焦油，聚芳烃（PAH）和原煤气厂的学校场地的氰化物污染进行修复。在此案例研究中选择的补救措施是对污染土壤进行异地热处理进行开挖。与各种LCA货币化方法的成果相比，严格地将社会CBA的成果（指出该修复项目从长远来看对社会有益）进行了比较。这种比较表明，在评估次要环境影响时，货币化的LCA是社会CBA的良好补充。两种方法的结合为决策者提供了对土壤修复项目的更广泛，更详细的评估。与不同的LCA货币化方法的结果进行了严格的比较。这种比较表明，在评估次要环境影响时，货币化的LCA是社会CBA的良好补充。两种方法的结合为决策者提供了对土壤修复项目的更广泛，更详细的评估。与不同的LCA货币化方法的结果进行了严格的比较。这种比较表明，在评估次要环境影响时，货币化的LCA是社会CBA的良好补充。两种方法的结合为决策者提供了对土壤修复项目的更广泛，更详细的评估。
