Since 1990s, subsurface contamination associated with the growing oil and gas sector in Atlantic Canada has been acquiring much attention. The proposed research will integrate physical experimentation and numerical computer models into a general framework for generating novel engineering solutions to petroleum-contamination issues within this region. The proposed research will include the following specific research programs: (1) development of porous-media enhancement techniques (i.e., prefabricated horizontal/vertical drains and bio-barrier systems) for improving in-situ bioremediation design; (2) custom-design of alternative chemical-carriers for enhancing DNAPLs removal; (3) development of effective heavy-metal removal techniques (e.g., reusable bio-sorbents, in situ containment of heavy metals, and microbial plugging isolation); (4) dynamic modeling of remediation process and real-time control for optimal remediation system design. The novelty of this research is the extensive use of both experimental and computational tools for R&D of remediation technologies. As subsurface contamination events occurred in the fields are "unseeable", it is highly desired to be able to "see" these objects/events with the aid of certain tools. Therefore, the proposed programs choose to use experimentations and computer models to develop understandings of flow-transport and contamination-restoration processes and to clearly visualize "unseeable" contamination and cleanup events. This beauty could lead to economically feasible and effective remediation designs. The proposed research will be the first comprehensive subsurface contamination-remediation experimental-modeling system in Atlantic Canada. The developed technologies will help Canadian governments improve their effectiveness in managing subsurface pollution problems associated with not only petroleum industries but also many other practices. It will also benefit industrial partners by providing cost-effective methods for pollution control and abatement. The research products will be eventually commercialized for helping Canadian industries with both improved environmental and economic efficiencies.

自 20 世纪 90 年代以来，与加拿大大西洋地区不断增长的石油和天然气行业相关的地下污染一直受到广泛关注。拟议的研究将把物理实验和数值计算机模型整合到一个通用框架中，为该地区的石油污染问题产生新颖的工程解决方案。拟议的研究将包括以下具体研究计划：（1）开发多孔介质增强技术（即预制水平/垂直排水沟和生物屏障系统）以改进原位生物修复设计； (2) 定制设计替代化学载体以增强 DNAPL 去除； （3）开发有效的重金属去除技术（例如可重复使用的生物吸附剂、重金属原位遏制和微生物堵塞隔离）； (4)修复过程的动态建模和实时控制，以实现最优修复系统设计。这项研究的新颖之处在于广泛使用实验和计算工具来研发修复技术。由于现场发生的地下污染事件是“看不见的”，因此非常希望能够借助某些工具“看到”这些物体/事件。因此，拟议的程序选择使用实验和计算机模型来加深对流动传输和污染恢复过程的理解，并清晰地可视化“不可见的”污染和清理事件。这种美丽可以带来经济上可行且有效的修复设计。拟议的研究将是加拿大大西洋地区第一个综合性地下污染修复实验模型系统。所开发的技术将帮助加拿大政府提高管理地下污染问题的效率，这些问题不仅与石油工业有关，而且还与许多其他实践有关。它还将通过提供具有成本效益的污染控制和减排方法来使工业合作伙伴受益。这些研究产品最终将商业化，以帮助加拿大工业提高环境和经济效率。
