Hydrocarbon-based resources are still indispensable sources of energy and one of the core elements driving economic growth in Canada. However, the intensified extraction of hydrocarbon energy resources is posing environmental risks to surrounding soil and groundwater resources. Numerous oilfield sites are impacted simultaneously by hydrocarbons (organic) and co-extracted salts and/or metals (inorganic), and mixed contamination at Canadian sites, including northern sites, is a pressing environmental concern for which the costs of remediation are prohibitively increased by multiple challenging conditions. In collaboration with Imperial Oil and PINTER & Associates, Dr. Wonjae Chang (Principal Investigator) and his research team will focus on hybrid bioremediation and desalination (HBD) technologies specialized for mixed organic and inorganic contaminants in environmentally challenging conditions. We aim to synergistically combine biological and physicochemical remediation processes for the removal of hydrocarbons, Na+ and Cl- (and other environmentally significant anions) from impacted soils, saline leachate and groundwater. The two key elements of the HDB process are (1) native, halotolerant, cold-adapted bacteria capable of degrading hydrocarbons during desalination, and (2) natural and engineered minerals that can readily incorporate salt cations and anions into their mineral frameworks. The HBD process is an innovative concept that will broadly foster the development of remediation technologies specialized for mixed contamination. This research is on the frontline of Canada's innovation for sustainable development and the environment. It will be beneficial to public safety and the environmental sustainability of Canadian energy. This research will contribute to meeting Canada's needs today and will become a high-impact research field for Canada's future.

基于烃的资源仍然是必不可少的能源来源，也是推动加拿大经济增长的核心因素之一。但是，碳氢化合物能量资源的提取的加剧正在为周围的土壤和地下水带来环境风险。许多油田地点同时受到碳氢化合物（有机）和联合提取的盐和/或金属（无机）的影响，以及包括北部遗址在内的加拿大地点的混合污染，这是一个紧迫的环境问题，这是一种紧迫多个挑战性条件。 Wonjae Chang（首席研究员）和他的研究团队将与帝国石油和Pinter＆Associates合作，将重点放在混合生物修复和脱盐（HBD）技术上，专门针对环境挑战性条件的混合有机和无机污染物。我们的目的是结合生物学和物理化学补救过程，从而从受影响的土壤，盐水渗滤液和地下水中去除碳氢化合物，Na+和Cl-（以及其他具有环境意义的阴离子）。 HDB工艺的两个关键要素是（1）天然，甲状化，冷适应的细菌，能够在脱盐过程中降解碳氢化合物，以及（2）自然和工程矿物质，可以很容易地将盐阳离子和阴离子掺入其矿物框架中。 HBD过程是一个创新的概念，它将广泛促进专门用于混合污染的补救技术的发展。这项研究是加拿大为可持续发展和环境创新的前线。它将对加拿大能源的公共安全和环境可持续性有益。这项研究将有助于满足加拿大今天的需求，并将成为加拿大未来的高影响力研究领域。
