This is an award to support research on contaminant interactions with clays used in containment of structures for storing hazardous wastes. The objectives of this research include quantification of the structural changes in clays when they are permeated by organic fluids, determination of the distribution pattern of contaminants in these clays, and examination of the feasibility of removing volatile organic compounds from these clays by a vapor extraction process. This proposal was submitted in response to Program Announcement NSF 88-99, Research Initiation Awards. Results are expected to improve the engineering design of containment ponds, landfills, waste covers and slurry walls associated with storage of hazardous solids and liquids. Results may also be applied in a process for decontamination of contaminated soils by vapor extraction alone or in combination with another physical process, and/or chemical and biologically-based remediation systems.

这一奖项旨在支持对用于储存危险废物的结构容器的粘土与污染物相互作用的研究。本研究的目的包括定量测定有机流体渗透后粘土的结构变化，确定这些粘土中污染物的分布模式，并考察了通过蒸汽萃取法从这些粘土中去除挥发性有机化合物的可行性。本提案是根据NSF项目公告88-99，研究启动奖而提交的。预计研究结果将改进与储存危险固体和液体有关的围堵池、垃圾填埋场、废物盖和泥浆墙的工程设计。结果也可以应用于通过蒸汽萃取单独或与另一物理过程和/或基于化学和生物的修复系统相结合来净化污染土壤的过程。
