The project will significantly advance and integrate three sophisticated contaminated site characterization tools: stable isotope analysis, microbial community profiles, and 3D reactive transport modeling. These three tools will be applied to a series of poorly studied semi volatile compounds, including (di)chloronitrobenzenes and (di)chloroanilines, and incorporated in a conceptual site model along with concentration profiles and hydrogeological data to identify cost-effective remediation strategies. The results of this project will be applicable to many other complex sites to quantify and mechanistically define actual biotransformation reactions and identify areas where remediation actions are required.

该项目将大大推进和整合三个复杂的污染场地表征工具：稳定同位素分析，微生物群落概况和3D反应运输建模。这三种工具将用于一系列研究不足的半挥发性化合物，包括（二）氯硝基苯和（二）氯苯胺，并将其与浓度分布图和水文地质数据沿着纳入一个概念性场地模型，以确定具有成本效益的补救战略。该项目的结果将适用于许多其他复杂的场地，以量化和机械地确定实际的生物转化反应，并确定需要采取补救行动的领域。
