ABSTRACTEEC-9820162LEDERMAN Contaminated ground water imperils our water supply. The biodegradability of hydrocarbon contaminants in soils is effected by sorption processes, intraparticle diffusion and the effects of aging and the availability of electron acceptors. These processes are not fully understood. Predictive models based on physical chemical and biochemical properties of both the contaminants and soils are needed. This three year project brings together the New Jersey Institute of Technology Industry/University Cooperative Research Center (I/UCRC) for Hazardous Waster Management and the French INSA de Lyon Center, Association Reseau Cooperatif de Recherche sur les Dechets (ReCoRD) to address these needs.The collaborative project will study laboratory scale batch and soil column tests to determine the characteristic physical and biochemical parameters required for model development. The model will be validated by field test data from sites contaminated with cool tar constituents.The French will develop the microscale characterization of the surface interactions between pollutants and the soils. The U.S. researchers will develops a mathematical predictive model and test it with laboratory and field tests. One third of the U.S. component of this collaborative project will be funded by the I/UCRC. The French Government will fund their component.

受污染的地下水危及我们的供水。土壤中烃类污染物的生物降解性受吸附过程、颗粒内扩散、老化和电子受体有效性的影响。这些过程还没有被完全理解。需要基于污染物和土壤的物理、化学和生化特性的预测模型。这个为期三年的项目汇集了新泽西技术工业研究所/大学危险废物管理合作研究中心（I/UCRC）和法国里昂国家科学技术研究所中心、清洁技术研究合作协会（ReCoRD）来解决这些需求。该合作项目将研究实验室规模的批量和土柱测试，以确定模型开发所需的特征物理和生化参数。该模型将通过来自受冷焦油成分污染地点的现场测试数据进行验证。法国人将发展污染物与土壤表面相互作用的微观表征。美国研究人员将开发一个数学预测模型，并通过实验室和现场测试对其进行测试。这个合作项目的美国部分的三分之一将由I/UCRC资助。法国政府将为其组成部分提供资金。
