Integrated brownfield subsurface remediation technology development

由于城市基础设施的破坏，城市中心内的许多碳氢化合物污染的地下场所不能被挖掘，因此，公司通过确保有足够的氧（O2）、磷（P）和偶尔的氮来现场刺激碳氢化合物的降解，以用于碳氢化合物的降解。然而，这个相对简单的目标是具有挑战性的，因为当碳氢化合物降解和修复“停滞”时，O2和P迅速耗尽。Federated Coop Limited（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，低分子量有机酸（LMOA）和真菌。然而，这些方法中的每一种都是孤立地开发的，并且还不是一贯有效的。FCL与萨斯喀彻温省应用科学与技术研究所（SIAST）和萨斯喀彻温大学（U of S）合作，开发综合布朗菲尔德地下修复技术。基于NSERC Engage项目，FCL已与萨斯喀彻温大学和SIAST接洽，以满足他们的科学和技术需求。由Siciliano领导的美国研究小组已经获得了两项NSERC赠款调查土壤中的真菌和LMOA， 许多与布朗菲尔德相关的赠款。总之，这个大学和学院团队拥有将FCL地下修复方法集成到布朗菲尔德修复的单一技术平台所需的专业知识，经验和技术诀窍。 我们将使用实验室和现场实验，以确定最佳的P，LMOA和真菌组合的碳氢化合物降解方法。我们将在萨斯卡通的一个布朗菲尔德场地测试实验室结果，以评估综合技术方法是否有效，并在其他八个不同的场地试用拟议的技术。在该项目结束时，FCL，SIAST和美国将拥有一个集成的地下技术。

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.
