沉积基岩(即基岩含水层)中的地下水是**加拿大和全球最重要的淡水来源；然而，由于各种人类活动，这些含水层中的许多都受到了污染。**氯有机溶剂是地下水中最常见的工业污染物。由于过度依赖糟糕的表征工具，人们对地下条件如何影响这些污染物从源头地区转移到接收器的**知之甚少。Parker博士和她的NSERC工业研究主席**关于裂隙岩石中的地下水污染**(自2007年以来一直担任)，利用新的**技术和应用于真实受污染地点的详细的现场和实验室测量，克服了这些限制。帕克博士和她的研究团队表明，污染物通过岩石裂隙从源头快速移动，但由于**扩散到通过许多活动裂隙进入的基岩孔隙，污染物被吸附到矿物质中，并**由于自然发生的化学和微生物反应而缓慢降解。在几十年的时间里，羽流**变得静止，甚至退回到源头地区。未来五年的研究将使用**测量和计算机建模的洞察力来预测未来的条件和自然或增强**修复的速度，以加快清理工作。结果将对世界各地的沉积岩含水层有用，为**关于地下水污染对供水井和生态系统的威胁以及如何**保护两者的决策提供信息。这项工作实现了对污染场地的可靠、经济高效的管理和最终的清理，并**使加拿大人在地下水科学、技术制造和资源保护**方面处于世界领先地位。这是通过在真实世界的地点进行学生实践培训以及改进方法和**技术来保护对维持生命至关重要并支持食品生产和**制造业的全球资源来实现的。

Groundwater in sedimentary bedrock (i.e., bedrock aquifers) is the most important source of fresh water in**Canada and globally; however, many of these aquifers are polluted due to a large variety of human activities.**Chlorinated organic solvents are the most common industrial contaminant found in groundwater. Little is**known about how subsurface conditions affect movement of these contaminants from source areas to receptors**because of over-reliance on poor characterisation tools. Dr. Parker, with her NSERC Industrial Research Chair**on Groundwater Contamination in Fractured Rock (held since 2007), has overcome these limitations using new**technologies and detailed field and laboratory measurements applied to real contaminated sites. Dr. Parker and**her research team show that pollutants move quickly from their source through rock fractures but are slowed by**spreading into the bedrock pores accessed through many active fractures where they are sorbed to minerals and**slowly degrade due to naturally occurring chemical and microbial reactions. Over many decades the plumes**become stationary or even retreat back toward source areas. The next five years of research will use**measurement and computer modeling insights to predict future conditions and rates of natural or enhanced**remediation to hasten cleanup. Results will be useful for sedimentary rock aquifers worldwide, informing**decisions regarding groundwater contamination threats to water supply wells and ecosystems, and how to**protect both. This work enables reliable, cost-effective management and eventual cleanup of polluted sites and**positions Canadians as world leaders in groundwater science, technology manufacturing, and resource**protection. This is achieved through hands-on student training at real-world sites and improved methods and**technologies for protecting a global resource that is critical for sustaining life and supports producing food and**manufacturing.
