Groundwater in sedimentary bedrock (i.e., bedrock aquifers) is the most important source of fresh water inCanada 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 isknown about how subsurface conditions affect movement of these contaminants from source areas to receptorsbecause of over-reliance on poor characterisation tools. Dr. Parker, with her NSERC Industrial Research Chairon Groundwater Contamination in Fractured Rock (held since 2007), has overcome these limitations using newtechnologies and detailed field and laboratory measurements applied to real contaminated sites. Dr. Parker andher research team show that pollutants move quickly from their source through rock fractures but are slowed byspreading into the bedrock pores accessed through many active fractures where they are sorbed to minerals andslowly degrade due to naturally occurring chemical and microbial reactions. Over many decades the plumesbecome stationary or even retreat back toward source areas. The next five years of research will usemeasurement and computer modeling insights to predict future conditions and rates of natural or enhancedremediation to hasten cleanup. Results will be useful for sedimentary rock aquifers worldwide, informingdecisions regarding groundwater contamination threats to water supply wells and ecosystems, and how toprotect both. This work enables reliable, cost-effective management and eventual cleanup of polluted sites andpositions Canadians as world leaders in groundwater science, technology manufacturing, and resourceprotection. This is achieved through hands-on student training at real-world sites and improved methods andtechnologies for protecting a global resource that is critical for sustaining life and supports producing food andmanufacturing.

沉积基岩中的地下水（即基岩含水层）是淡水淡水incanada和全球最重要的来源。但是，许多这些含水层由于各种各样的人类活动而受到污染。氯有机溶剂是地下水中最常见的工业污染物。关于地下条件如何影响这些污染物从源区域到受体的运动几乎没有众所周知，因为过度依赖差的特征工具。 Parker博士及其NSERC工业研究主席地下水污染（自2007年以来举行）（自2007年以来举行），使用了新技术技术以及适用于实际污染地点的详细领域和实验室测量来克服这些局限性。 Parker Andher Research Team博士表明，污染物通过岩石裂缝迅速从其来源移动，但由于许多活跃的骨折而被散布到基岩毛孔中，因为它们由于化学物质和微生物反应而自然出现，因此被矿物质和山顶降解。数十年来，羽毛状固定或什至撤回源区域。接下来的五年研究将进行使用和计算机建模见解，以预测自然或增强的未来条件和速度以加速清理。结果对于全球沉积岩石含水层，有关地下水污染威胁的供水井和生态系统的威胁以及如何使两者兼而有之，结果将很有用。这项工作使作为地下水科学，技术制造和资源保护的世界领导者，可靠，具有成本效益的管理以及最终清理污染的地点和位置加拿大人。这是通过在现实世界网站上动手的学生培训以及改进的方法和技术来保护全球资源的方法和技术来实现的，这对于维持生命和支持生产食品和制造至关重要。
