This is an award to support a project to determine the transport, fate, and effects produced by protozoa in a plume of organically contaminated groundwater as influenced by physical and chemical conditions of the contaminated aquifer, and to determine the role that protozoa play in influencing the numbers and kinds of bacteria that survive transport through a contaminated aquifer. This project includes field studies in cooperation with the U.S. Geological Survey (Ronald W. Harvey) at its Groundwater Contamination Site located at the Otis Air Force Base on Cape Cod, Massachusetts. The project also includes a subcontract with the British Museum of Natural History (Colin R. Curds). This project addresses factors of great significance in determining the role that protozoa play in affecting microbial populations in aquifers that have been contaminated by organic chemicals. Results may be applied in engineering design of systems for decontamination of aquifers by use of a bioremediation process alone or as part of a system including physical and chemical processes.

这是一个支持项目的奖项，以确定 运输，命运和原生动物在一个 被有机污染的地下水 受环境的物理和化学条件的影响， 受污染的含水层，并确定 原生动物在影响 细菌通过污染的 含水层 该项目包括实地研究， 与美国地质调查局（罗纳德W。 Harvey）位于 位于马萨诸塞州科德角的奥蒂斯空军基地。 的 该项目还包括与英国 自然历史博物馆（Colin R.凝乳）。 该项目涉及的重要因素， 决定了原生动物在影响 地下水中的微生物数量 被有机化学物质污染。 结果可以应用 在工程设计中， 单独或作为一种生物补救方法， 系统的一部分，包括物理和化学 流程.
