Assessment and optimization of bioretention soil media for enhanced removal of stormwater contaminants in bioretention systems

城市雨水导致了加拿大地表水质量的恶化。低影响发展雨水管理技术是一种日益流行的减少雨水对流域影响的方法。生物截留系统就是这样一种需求迅速增长的技术，它是一种可渗透的路边洼地，用于截留和改善雨水的质量。C.F. Crozier & Associates是一家专注于土地开发和水资源项目的咨询工程公司，该公司已经确定需要优化生物保留系统中使用的工程土壤介质的组成，以保留和去除雨水中的污染物。西方**大学的研究人员将把现有的田间规模生物保持系统的评估与先进的土壤柱实验室实验相结合，以测试和开发新的生物保持土壤成分，以解决田间规模系统性能中发现的关键缺陷。C.F. Crozier & Associates将把该项目的研究结果应用于未来生物滞留系统装置的设计中，以提高系统性能、延长使用寿命并降低维护成本。这项研究将有助于C.F. Crozier & Associates成为LID技术设计和实施的领导者。公司形象的提升将使C.F. Crozier & Associates**获得更多的项目合同，吸引新客户，雇佣更多的高素质人才，并最终**增加公司收入。

Urban stormwater contributes to the deterioration of surface water quality across Canada. Low impact**development stormwater management technologies are an increasingly popular approach to decrease the impacts**of stormwater on the watershed. Bioretention systems, which are permeable vegetated road side depressions**designed to retain and improve the quality of stormwater, are one such technology for which demand is rapidly**growing. C.F. Crozier & Associates, a consulting engineering company focused on land development and water**resource projects, has identified the need for optimization of the composition of the engineered soil media used in**bioretention systems with respect to its ability to retain and remove contaminants from stormwater. Western**University researchers will combine evaluation of existing field-scale bioretention systems with advanced soil**column laboratory experiments to test and develop new bioretention soil compositions that address key**deficiencies identified in the performance of field-scale systems. C.F. Crozier & Associates will apply the project**findings in the design of future bioretention system installations to improve system performance, longevity and**reduce maintenance costs. This research initiative will help position C.F. Crozier & Associates as leaders in the**design and implementation of LID technologies. An elevated company image will enable C.F. Crozier & Associates**to retain more project contracts, attract new clients, employ additional highly qualified personnel, and ultimately**result in increased company revenues.
