RESEARCH INITIATION AWARD: In-Situ Transformation and Transport of Surfactants in Sewage-Contaminated Groundwater

这是一个支持表面活性剂在含水层中运移研究的奖项。研究人员计划首先研究线性烷基苯磺酸表面活性剂在受污水污染的地下水含水层的氧化区和未受污染的地下水的氧化区中生物降解的情况，地点由美国地质调查局位于马萨诸塞州科德角的奥蒂斯空军基地试验场负责。随后的阶段将包括向污染地下水的缺氧区连续注入表面活性剂，以确定表面活性剂开始降解所需的滞后时间。预计该项目的结果将包括提高对影响地下水中表面活性剂命运和运输的过程的理解。这反过来又会影响基于使用表面活性剂从受污染的含水层中去除污染物的系统的工程设计。* * *

Field 9409171 This is an award to support research on surfactant transport in aquifers. The investigator plans initially to study the biodegradation of linear alkylbenzenesulfonate surfactants in an oxygenated zone of a wastewater-contaminated groundwater aquifer and in an oxygenated zone of uncontaminated groundwater at a field location operated by the U.S. Geological Survey's Otis Air Force Base test site on Cape Cod in Massachusetts. A subsequent phase will involve the continuous injection of a surfactant into the oxygen-depleted zone of contaminated groundwater to determine the lag time required to initiate degradation of the surfactant. Results of this project are expected to include an improved understanding of the processes that affect surfactant fate and transport in groundwater. This in turn is expected to influence the engineering design of systems based on use of surfactants to remove contaminants from contaminated aquifers. ***
