Since 2013, the Restoration of Labrador Exploration Sites (ROLES) program was initiated and led by Altius Minerals Corporation (Altius) in collaboration with several partners to identify and clean abandoned mining exploration sites throughout Labrador. To date, ROLES has identified 134 potential sites requiring remediation in the region. Efficient and cost-effective site characterization and remediation methods are thus highly desired by Altius. Monitored natural attenuation (MNA) has been accepted as one of the most cost-effective and ecologically friendly techniques for conducting integrated site characterization and remediation. However, the monitoring of microbial activities during a MNA process relies heavily on the placement of the individual monitoring well, which is very time consuming and expensive. To help fill the knowledge and technical gaps, the proposed research project will investigate the feasibility of applying Monitored Natural Attenuation (MNA) to an oil-contaminated site 79a in Inuit area, Labrador. The project will (1) develop a promising Direct-Push microcosm bacterial trap (DP-BACTRAP) approach for evaluating the applicability of MNA without drilling monitoring wells in the context of Labrador; and (2) screen and isolate indigenous, cold-adaptable, oil degrading microorganism strains from site samples to facilitate future remediation actions. The project is expected to develop an advanced site characterization and remediation approach. Through transferring the anticipated IP to Altius, the research outputs can be directly applied to other contaminated sites within the scope of ROLES and beyond, greatly simplify the site characterization and help industrial partners including Altius to decrease site remediation cost. The project will also lead to an improved and healthier working and living environment for Canadians, especially the Inuit community in Labrador.

自2013年以来，拉布拉多勘探地点恢复（ROLES）计划由Altius发起并领导 Minerals Corporation（Altius）与多个合作伙伴合作，识别和清理废弃采矿 在拉布拉多各地的探险地点。到目前为止，ROLES已经确定了134个需要补救的潜在地点 本地区因此，非常需要有效和具有成本效益的场地特征描述和补救方法 关于Altius间接自然衰减（MNA）已被公认为最具成本效益和 采用无害生态的技术，进行综合的场地特性鉴定和补救。但 在多边核方案过程中，对微生物活动的监测在很大程度上依赖于个人的安置， 监测井，这是非常耗时和昂贵的。 为了填补知识和技术上的空白，拟议的研究项目将研究以下方面的可行性： 对拉布拉多因努伊特地区79 a石油污染场地进行了自然衰减法（MNA）的应用研究。的 该项目将（1）开发一种有前途的直接推动微观世界细菌陷阱（DP-BACTRAP）方法， 在拉布拉多的情况下，评价不钻监测威尔斯井的多边核方案的适用性;以及（2） 从现场样品中筛选和分离本土的、冷适应的、石油降解微生物菌株， 为今后的补救行动提供便利。该项目预计将开发一个先进的网站特性， 补救办法。通过将预期的IP转移到Altius，研究成果可以直接 适用于ROLES范围内及以外的其他污染场地，大大简化场地 表征和帮助包括Altius在内的工业合作伙伴降低现场修复成本。该项目将 也为加拿大人，特别是因纽特人，带来更好、更健康的工作和生活环境。 拉布拉多的社区
