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 IRC 项目的第一期，我们开发并展示了一种可靠的技术，可在六个受汽油或柴油污染的地点减少 90% 以上的碳氢化合物。 IRC 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减少到最低水平。我们假设磷酸盐、镁、柠檬酸盐、硫酸盐、铁和硝酸盐等肥料成分达到最佳平衡，这将刺激强大的降解微生物群落。我们将开发新的方法来计算许多不同草原土壤类型的最佳平衡。为了开发新的计算，我们将确定与成功修复相关的微生物和离子的平衡，然后创建新的肥料混合物，以刺激整个加拿大西部的成功修复。我们假设添加到生物刺激溶液中的有机或脂肪酸可能对这种痕量修复至关重要，或者存在与痕量修复相关的有机磷化合物。或者，在碳氢化合物浓度非常低的情况下，微生物和矿物质之间的相互作用可能会变得更加重要，我们需要了解矿物质如何控制修复。第一个 IRC 术语为 36 名人员提供了培训，其中 20 名是女性，第二个术语为 36 名人员提供了培训，其中 20 名是女性。 该阶段预计再培训 19 至 40 名人员。学生很容易在环境领域找到工作，因为学生与行业密切合作，建立软技能和商业网络。通过这样做，IRC 项目为学生从学术培训到在其所选研究领域就业提供了一个理想的桥梁。在 IRC 第二学期结束时，我们将开发、部署和验证一种经济上可行的方法
