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. ***

Field 9409171这是一个支持含水层中表面活性剂传输研究的奖项。 调查人员最初计划研究直链烷基苯磺酸盐表面活性剂在废水污染的地下水含水层的充氧区和未污染的地下水的充氧区中的生物降解，该充氧区位于马萨诸塞州科德角的美国地质调查局奥蒂斯空军基地试验场。 下一阶段将涉及向受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。 该项目的成果预计将包括更好地了解影响表面活性剂的命运和地下水中的运输过程。 这反过来又会影响到基于使用表面活性剂从受污染的含水层中清除污染物的系统的工程设计。 ***
