The research proposed here will allow Canada to make informed decisions regarding remediation technology selection and expectations at fractured bedrock sites impacted by organic compounds such as chlorinated solvents, polychlorinated biphenyls (PCBs), fuels (e.g., gasoline and diesel), creosote, and coal tar. These organic compounds constitute the most frequently encountered type of groundwater contaminants at sites throughout Canada, the United States and other industrialized countries around the world. Given the relatively thin cover of unconsolidated deposits (overburden) throughout much of Canada, fractured bedrock is often impacted as a result of contaminant releases at ground surface. Example Canadian sites include the occurrence of organic compounds in bedrock at Ville Mercier south of Montreal, Quebec; the occurrence of PCBs and chlorinated solvents in bedrock at Smithville, Ontario; and the occurrence of chlorinated solvents, fuels, creosote, and coal tar at numerous sites in all provinces and territories throughout Canada. Fractured bedrock is a valued resource in Canada given its ability to provide drinking water and its intimate connection with the hydrologic cycle. At present, very few options exist to remediate fractured bedrock sites, particularly for older sites where significant amounts of contaminant mass have diffused into the rock matrix over time. There is currently a very limited base of experience in Canada regarding the use of thermal and other in-situ remediation technologies in either unconsolidated or consolidated deposits. This research will equip stakeholders (site owners, regulators, politicians, vendors, consultants, community groups) with both realistic expectations and the knowledge required to properly implement in-situ groundwater remediation technologies at fractured bedrock sites throughout Canada. This research is not only aimed at developing and evaluating remediation technologies; it is aimed at training highly qualified personell that will have a beneficial influence on decision making throughout Canada.**********

此处提出的研究将使加拿大能够在受到有机化合物（例如氯化溶剂，多氯联苯二苯基（PCB），燃料（例如汽油和柴油），Creosote和Creosote和Coal Coal Tar的有机化合物影响下，对补救技术的选择和期望做出明智的决定。 这些有机化合物构成了加拿大，美国和世界其他工业化国家的地下水污染物最常遇到的类型。 鉴于整个加拿大大部分地区的未固结沉积物（覆盖层）的覆盖率相对较薄，因此底层破裂的底石通常由于地面污染物的释放而受到影响。 示例加拿大遗址包括魁北克蒙特利尔南部的维尔·梅塞尔（Ville Mercier）基岩中的有机化合物的出现；安大略省史密斯维尔基岩的PCB和氯化溶剂发生；以及加拿大各省和地区的许多地点的氯化溶剂，燃料，杂糖和煤焦油的发生。 鉴于其能够提供饮用水及其与水文循环的紧密联系的能力，破裂的基岩是加拿大有价值的资源。 目前，几乎没有选择补救断裂的基岩部位，特别是对于较旧的地点，随着时间的推移，大量污染物质量已经扩散到岩石基质中。 目前，在加拿大，在未固结或合并的沉积物中使用热和其他原位补救技术的经验基础非常有限。 这项研究将使利益相关者（现场所有者，监管机构，政客，供应商，顾问，社区群体）既有现实的期望，又可以在整个加拿大裂缝基岩地点正确实施现场地下水补救技术所需的知识。 这项研究不仅旨在开发和评估补救技术；它旨在培训高素质的人员，这将对整个加拿大的决策产生有益的影响。**********
