Benchmark Experiments in Aquifer Remediation of Light Nonaqueous Phase Liquid Contaminants Using Surfactants

9705184席瓦利埃这是一个支持使用表面活性剂改变流体的界面张力的初步工作的奖项，该界面张力改变了流体在它们被污染的含水层中运动的特征。该项目涉及模拟使用泵来提取受污染含水层的汽油等非水流体的程序。这项研究将通过实验室规模的模型进行，该模型可用于研究表面活性剂对毛细、重力和粘性力的影响，这些力影响流体在多孔和可渗透的地下地层中的运动。导致这一奖项的提案是为了回应NSF关于女性科学家和工程师的研究规划补助金和职业发展奖的计划公告，NSF 93-130。预期结果将提供可用于确定拟研究过程的可行性的信息，并为进一步研究恢复受非水流体污染的含水层的水质奠定基础。***

9705184 Chevalier This is an award to support preliminary work on use of surfactants to alter the interfacial tension of fluids that change the characteristics of their movement through aquifers they have contaminated. The project involves procedures that simulate the use of pumps to withdraw non-aqueous fluids such as gasoline that have contaminated aquifers. The research will be conducted by use of a laboratory-scale model that can be used to study the effect of the surfactants on the capillary, gravitational and viscous forces that affect the motion of fluids through porous and permeable subsurface formations. The proposal leading to this award was submitted in response to an NSF Program Announcement for Research Planning Grants and Career Advancement Awards for Women Scientists and Engineers, NSF 93-130. Results are expected to provide information that can be used in determining the feasibility of the process to be studied and the basis for further research in restoration of water quality in aquifers contaminated by non-aqueous fluids. ***
