Examination of In-Situ Oil Spill Remediation at McMurdo Station

该提案将测试PES-51对溢油污染的原位生物修复。PES-51是一种从油降解菌中提取的表面活性剂。在进行现场测试之前，已经设计了一个使用麦克默多污染土壤的试验台规模测试项目。这些土壤将被运往阿拉斯加大学，以测试使用PES-51修复麦克默多土壤的可行性。设计了一个调查网格，以确定麦克默多过去作业中水平和垂直污染的范围和程度。这项调查将包括两个部分：1)汇编麦克默多站历史上的燃料泄漏文件；2)抽样程序，包括：A)初步绘制站周围“清洁”区域的地图，并划定污染区域；b)在已知污染区域制定详细的采样计划，以尽可能确定污染的垂直和水平范围；c)在其他清洁区域对小泄漏或孤立污染地点进行“热点”采样计划。

This proposal will test PES-51 for the in-situ bioremediation of oil spill contamination. PES-51 is a surfactant derived from oil- degrading bacteria. A bench-scale test program using contaminated soil from McMurdo has been designed to be completed before field testing can take place. The soil will be shipped to the University of Alaska to test the feasibility of remediating McMurdo soil using PES-51. A survey grid to determine the extent and degree of contamination in McMurdo from past operations, both horizontally and vertically has been designed. This survey will consist of two parts 1)a compilation of documentation of fuel spills over the history of McMurdo Station, and 2) a sampling program that includes: a) preliminary mapping of those areas around the station that are "clean" and to delineate contaminated areas, b) a detailed sampling program in known contaminated areas to determine the vertical and horizontal extent of the contamination to the degree possible, and c) a "hot spot" sampling program for small spills or isolated contamination sites in otherwise clean areas.
