Sporadic influx of oxygen-rich rainwater / groundwater into subsurface waste sites induces dramatic biogeochemical changes which greatly influence the transport of contaminants present. In this project, fundamental knowledge gaps regarding the impacts of redox oscillations upon contaminant behaviour in these sediments will be addressed through a comprehensive program of field studies at a purpose-constructed experimental facility in an existing waste site, and complementary laboratory investigations. The intended outcomes are to improve understanding of contaminant mobility at the field-scale in these pervasive sites spread across the globe, and provide critical insight into their remediation using cost-effective techniques.

富氧雨水/地下水零星流入地下垃圾场会引起剧烈的生物地球化学变化，从而极大地影响存在的污染物的迁移。在这个项目中，基本知识的差距，氧化还原振荡的影响后，这些沉积物中的污染物的行为将通过一个全面的计划，在一个专门建造的实验设施，在现有的废物场，并补充实验室调查的实地研究。预期的结果是提高对污染物流动性的理解，在这些遍布地球仪的普遍网站在现场规模，并提供关键的洞察力，他们的补救使用具有成本效益的技术。
