Many hydrocarbon contaminated subsurface sites within urban centers can not be excavated because of disruption to the city's infrastructure and thus, companies stimulate degradation of hydrocarbons onsite by insuring that there is sufficient oxygen (O2), phosphorus (P), and occasionally nitrogen, for hydrocarbon degradation. However, this relatively simple goal is challenging because O2 and P are rapidly depleted when hydrocarbons are degraded and remediation 'stalls'. Federated Coop Limited (FCL) has developed a suite of technologies to avoid this remediation stall: namely, alternative P species, low molecular weight organic acids (LMOA) and fungi. However, each of these approaches was developed in isolation and is not yet consistently effective. FCL has partnered with the Saskatchewan Institute of Applied Science and Technology (SIAST) and the University of Saskatchewan (U of S) to develop an integrated brownfield subsurface remediation technology. Based on a NSERC Engage project, FCL has approached the University of Saskatchewan and SIAST to address their scientific and technical needs. The U of S team led by Siciliano, has had two NSERC grants investigating fungi and LMOA in soil as well as numerous Brownfield related grants. Together, this University and College team has the expertise, experience and know-how needed to integrate FCLs subsurface remediation approaches into a single technology platform for brownfield remediation. We will use laboratory and site experiments to identify optimal P, LMOA and fungi combined approaches for hydrocarbon degradation. We will test lab results at a Saskatoon brownfield site to evaluate the integrated technology approach will work and trial the proposed technology across eight different other sites. At the conclusion of this project, FCL, SIAST and the U of S will have an integrated subsurface technology.

由于城市基础设施的中断，城市中心内许多被碳氢化合物污染的地下场地无法挖掘，因此，公司通过确保有足够的氧气(O2)、磷(P)，有时还有氮气来进行碳氢化合物降解，从而刺激现场碳氢化合物的降解。然而，这一相对简单的目标具有挑战性，因为当碳氢化合物被降解时，O2和P会迅速耗尽，修复工作陷入停滞。联合鸡舍有限公司(FCL)已经开发了一套技术来避免这种补救停滞：即替代P物种、低分子有机酸(LMOA)和真菌。然而，这些方法中的每一种都是单独开发的，而且还不是一致有效的。FCL已与萨斯喀彻温省应用科学技术研究所(SIAST)和萨斯喀彻温省大学(S大学)合作开发综合棕地地下修复技术。基于NSERC Engage项目，FCL已与萨斯喀彻温省大学和SIAST接洽，以满足他们的科学和技术需求。由西西里亚诺领导的S大学团队，已经获得了两项国家环境研究委员会的资助，研究土壤中的真菌和LMOA以及 许多与布朗菲尔德有关的赠款。该大学和学院团队共同拥有将FCLS地下修复方法集成到单一技术平台进行棕地修复所需的专业知识、经验和知识。 我们将通过实验室和现场实验来确定P、LMOA和真菌联合降解碳氢化合物的最佳方法。我们将在萨斯卡通的一个棕地场地测试实验室结果，以评估集成技术方法是否有效，并在其他八个不同的地点试验拟议的技术。在该项目结束时，FCL、SIAST和S的U将拥有一项完整的地下技术。
