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

9705184 Chevalier这一奖项是为了支持使用表面活性剂来改变流体的界面张力，从而改变其在被污染的含水层中的运动特性的初步工作。该项目包括模拟使用泵提取污染含水层的非水流体（如汽油）的程序。该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管力、重力和粘性力的影响，这些力会影响流体在多孔和渗透性地下地层中的运动。该提案是根据NSF研究计划资助和女性科学家和工程师职业进阶奖项目公告（NSF 93-130）提交的。预期结果将提供可用于确定所研究过程的可行性的信息，并为进一步研究受非水流体污染的含水层的水质恢复奠定基础。* * *

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. ***
