Municipal wastewater effluent (MWWE) represents the largest input of wastewaters to rivers in Canada, and a recent National Expert Advisory Panel Report on Challenges and Opportunities to Address Contaminants in Wastewater highlighted the continuing need to examine and address emerging issues. Pharmaceuticals andpersonal care product additives found in the Bow River, Alberta, have been associated with sublethal effects in aquatic organisms collected near MWWE discharges. With projections of population increases, developmental pressures in Rockyview and Foothills Counties, and warming temperatures over the next several decades, the risk in the Bow River will increase. This Project was initiated by the City of Calgary's search for studiesfocused on the impacts of MWWE discharges on the Bow River system, and it will work with a variety ofpartners and Indigenous communities to identify causes, evaluate future risks, and establish priorities forwastewater management. Knowledge gaps will be addressed with state-of-the-art evaluations on the relativeimportance of emerging substances of concern (ESOCs) associated with natural hormones, pharmaceuticals, and personal care products. The interplay between ESOCs and other stressors highlights the need for improved monitoring strategies that will allow a comprehensive and integrated assessment of multiple stressors and their effects. This project will train at least 26 HQP positions through 5 universities, including 15 URA, 4 MSc, 4 PhD, 2 PDF and 1 Community-based Researcher (CBR). Studies will use both unique experimental artificial stream facilities and in river measures to identify the environmental fate of ESOCs, detect food web-relatedchanges of concern, and identify sensitive physiological and microbiological tools for detecting early responsesand establishing exposure to MWWEs. Key relationships with Indigenous communities will identify priority issues and areas of concern for design and structure of future research phases. Designing and refiningmonitoring approaches for the largest source of discharges, by volume, are relevant to generate knowledge,tools, and solutions that can have a pan-Canadian impact and application.

城市废水是加拿大河流中最大的废水输入，最近国家专家咨询小组关于解决废水中污染物的挑战和机遇的报告强调了继续审查和解决新出现的问题的必要性。在阿尔伯塔弓河发现的药物和个人护理产品添加剂与MWWE排放物附近收集的水生生物的亚致死效应有关。随着人口增长的预测，罗克维尤县和山麓县的发展压力，以及未来几十年气温上升，弓河的风险将增加。该项目由卡尔加里市发起，旨在研究MWWE排放对弓河系统的影响，并将与各种合作伙伴和土著社区合作，以确定原因，评估未来风险，并确定废水管理的优先事项。知识差距将通过对与天然激素、药品和个人护理产品相关的新兴关注物质（ESOC）的相对重要性进行最新评价来解决。ESOC和其他压力源之间的相互作用突出了改进监测战略的必要性，这将允许对多种压力源及其影响进行全面和综合的评估。该项目将通过5所大学培训至少26名HQP职位，包括15名URA，4名MSc，4名PhD，2名PDF和1名社区研究员（CBR）。研究将使用独特的实验性人工溪流设施和河流措施，以确定ESOCs的环境命运，检测食物网相关的关注变化，并确定敏感的生理和微生物工具，用于检测早期反应和建立MWWE暴露。与土著社区的主要关系将确定未来研究阶段的设计和结构的优先问题和关注领域。设计和完善对最大排放源的监测方法，按排放量计算，对于产生知识、工具和解决方案具有相关意义，可以产生泛加拿大的影响和应用。
