项目摘要

Growth in the production, distribution and utilization of ethanol-blended fuels has raised the probability of accidental releases to the environment. This increased risk presents new challenges for contaminated site management and remediation, as detailed information on the fate of these biofuels in saturated and particularly unsaturated soils is lacking. The presence of ethanol may enhance the potential for methane and carbon dioxide generation, increase the risk of soil vapor intrusion by methane and volatile compounds of gasoline, and generate conditions non-conducive to gasoline degradation, causing these contaminants to persist in the soil atmosphere. Understanding the processes and conditions that regulate degradation of ethanol-blended fuels is therefore critical for assessing their long-term environmental fate and the potential for soil vapor intrusion into buildings and other underground infrastructure. Through this strategic project, we will develop and apply novel and innovative approaches to characterize the processes that control attenuation of biofuels in soils. In particular, we will conduct field and laboratory studies that integrate advanced techniques for measuring gas fluxes, soil microbial ecology, and compound-specific stable isotopes. We will integrate these data through development and implementation of novel process-based reactive transport models. The results of this strategic project will provide the tools needed to determine
乙醇混合燃料的生产、销售和使用的增长增加了向环境中意外释放的可能性。这种增加的风险对污染场地的管理和补救提出了新的挑战,因为缺乏关于这些生物燃料在饱和和特别是不饱和土壤中的命运的详细信息。乙醇的存在可能会增加甲烷和二氧化碳生成的可能性,增加甲烷和汽油挥发性化合物侵入土壤蒸汽的风险,并产生不利于汽油降解的条件,导致这些污染物在土壤大气中持续存在。因此,了解调节乙醇混合燃料降解的过程和条件对于评估其长期环境命运以及土壤蒸汽侵入建筑物和其他地下基础设施的可能性至关重要。通过这一战略项目,我们将开发和应用新颖和创新的方法来表征控制土壤中生物燃料衰减的过程。特别是,我们将进行实地和实验室研究,整合先进的技术来测量气体通量,土壤微生物生态学和化合物特定的稳定同位素。我们将通过开发和实施新的基于过程的反应性运输模型来整合这些数据。这一战略项目的结果将提供必要的工具,
