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

领域9409171这是一个支持表面活性剂在含水层中运移研究的奖项。该研究人员最初计划在马萨诸塞州科德角美国地质调查局的奥的斯空军基地试验场运营的野外地点，在受废水污染的地下水含水层的氧化带和未受污染的地下水的氧化带中研究直链烷基苯磺酸盐表面活性剂的生物降解。后续阶段将涉及将表面活性剂连续注入受污染地下水的缺氧区，以确定启动表面活性剂降解所需的滞后时间。预计该项目的成果将包括更好地了解影响表面活性物质在地下水中的去向和迁移的过程。这反过来预计将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. ***
