In the first term of this IRC program, we developed and demonstrated a reliable technique to reducehydrocarbons by over 90% at six sites polluted with gasoline or diesel. The goal of the second term of this IRCis to develop approaches that will further reduce hydrocarbons in soil to minimal levels.We hypothesize that there is an optimal balance of fertilizer components such as phosphate, magnesium,citrate, sulfate, iron, and nitrate that will stimulate a robust degrading microbial community. We will developnew ways to calculate what this optimal balance across the many different Prairie soil types.To develop the new calculations, we will identify the balance of microbes and ions associated with successfulremediation and then create a new fertilizer mix that will stimulate successful remediation across westernCanada. We hypothesize that organic or fatty acids added to the biostimulatory solution may be critical to thistrace remediation, or that there is an organic phosphorus compound associated with trace remediation.Alternatively, the interactions between microbes and minerals may increase in importance at very lowhydrocarbon concentrations and we need to understand how minerals control remediation.The first IRC term provided training for 36 personnel, of which 20 were women, and the second phaseenvisions training an additional 19 to 40 personnel. Students readily found employment in the environmentalsector because the students work closely with industry, building soft skills and a business network. In so doing,the IRC program provides an ideal bridge for students to cross from their academic training to employment intheir chosen field of study.At the conclusion of this second term of the IRC, we will have developed, deployed and validated aneconomically viable method

在该IRC计划的第一学期中，我们开发并证明了一种可靠的技术，可在六个被汽油或柴油污染的地点降低90％以上。该IRCIS第二学期的目标是开发方法，将土壤中的碳氢化合物进一步降低至最低水平。我们假设肥料成分（例如磷酸盐，镁，柠檬酸盐，硫酸盐，硫酸盐，铁和硝酸盐）具有最佳的平衡，从而刺激了强大的降解微生物群体。我们将开发新方法来计算在许多不同的草原土壤类型中的最佳平衡。要开发新的计算，我们将确定与成功制定相关的微生物和离子的平衡，然后创建一种新的肥料混合物，以刺激整个Westerncancanada的成功修复。我们假设将有机或脂肪酸添加到生物刺激性溶液中可能对这种疗法至关重要，或者存在与痕量补救相关的有机磷化合物。在线上，微生物和矿物质之间的相互作用可能会在非常低氢化的妇女身上的较低培训和矿物质的培训中提高，我们需要对矿物质的培训进行第二次培训。阶段visions培训了另外19至40名人员。学生很容易地在环保分子中找到就业，因为学生与行业紧密合作，建立软技能和业务网络。在这样做的过程中，IRC计划为学生提供了从学术培训到他们选择的学习领域就业的理想桥梁。
