Feasibility evaluation of monitored natural attenuation of a contaminated site in Labrador

自2013年以来，恢复拉布拉多探险遗址(ROLES)计划由Altius发起并领导 矿产公司(Altius)与几个合作伙伴合作，查明和清理废弃的采矿 拉布拉多各地的探险地点。到目前为止，角色已经确定了134个需要补救的潜在地点 在这一地区。因此，迫切需要高效和经济高效的场地表征和补救方法 阿尔修斯写的。监测自然衰减(MNA)已被认为是最具成本效益和 生态友好型技术，用于进行综合场地表征和修复。然而， 监测MNA过程中的微生物活动在很大程度上依赖于个人的安置 监测良好，这是非常耗时和昂贵的。 为了帮助填补知识和技术空白，拟议的研究项目将调查 对拉布拉多州因努伊特地区79a的石油污染场地应用监测的自然衰减(MNA)。这个 该项目将(1)开发一种有前途的直推式微观世界细菌捕捉器(DP-BACTRAP)方法，用于 在拉布拉多的情况下，在不钻探监测井的情况下评估监测网络的适用性；以及(2) 从现场样品中筛选和分离出适应寒冷的本土石油降解微生物菌株 促进未来的补救行动。该项目预计将开发先进的现场表征和 补救办法。通过将预期的IP转移到Altius，可以直接将研究成果 适用于其他受污染站点范围内及以外的角色，大大简化了站点 并帮助包括Altius在内的工业合作伙伴降低现场修复成本。该项目将 还为加拿大人，特别是因纽特人带来更好和更健康的工作和生活环境 拉布拉多的社区。

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.
