In the first term of this IRC program, we developed and demonstrated a reliable technique to reduce hydrocarbons by over 90% at six sites polluted with gasoline or diesel. The goal of the second term of this IRC is 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 develop new 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 successful remediation and then create a new fertilizer mix that will stimulate successful remediation across western Canada. We hypothesize that organic or fatty acids added to the biostimulatory solution may be critical to this trace 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 low hydrocarbon 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 phase envisions training an additional 19 to 40 personnel. Students readily found employment in the environmental sector 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 in their chosen field of study. At the conclusion of this second term of the IRC, we will have developed, deployed and validated an economically viable method

在这个IRC项目的第一学期，我们开发并展示了一种可靠的技术， 在六个受到汽油或柴油污染的地点，碳氢化合物减少了90%以上。第二届IRC的目标是 是开发将土壤中的碳氢化合物进一步减少到最低水平的方法。 我们假设肥料成分如磷酸盐，镁， 柠檬酸盐、硫酸盐、铁和硝酸盐，这将刺激一个强大的降解微生物群落。我们将开发 新的方法来计算这种最佳平衡在许多不同的草原土壤类型。 为了开发新的计算，我们将确定与成功的微生物和离子相关的平衡。 修复，然后创造一个新的肥料组合，将刺激整个西部地区的成功修复 加拿大我们推测，有机酸或脂肪酸添加到生物刺激解决方案可能是至关重要的， 痕量修复，或者存在与痕量修复相关的有机磷化合物。 或者，微生物和矿物质之间的相互作用可能在非常低的温度下增加重要性。 碳氢化合物浓度，我们需要了解矿物如何控制补救措施。 因诺琴蒂救济委员会第一期培训了36名工作人员，其中20名是妇女， 预计再培训19至40名人员。学生们很容易在环境中找到工作。 因为学生与行业密切合作，建立软技能和商业网络。在这样做时， IRC项目为学生从学术培训到就业提供了一个理想的桥梁， 他们选择的研究领域。 在IRC的第二个任期结束时，我们将开发、部署和验证一个 经济上可行的方法
