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.

城市废水排放 (MWWE) 是加拿大河流中最大的废水输入量，国家专家咨询小组最近发布的关于解决废水中污染物的挑战和机遇的报告强调了持续需要检查和解决新出现的问题。在阿尔伯塔省弓河发现的药品和个人护理产品添加剂与 MWWE 排放口附近收集的水生生物的亚致死作用有关。随着未来几十年人口增长、Rockyview 县和 Foothills 县的发展压力以及气温变暖的预测，弓河的风险将会增加。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原住民社区合作，查明原因、评估未来风险并确定废水管理的优先事项。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先进的评估来解决知识差距。 ESOC 与其他压力源之间的相互作用凸显了改进监测策略的必要性，以便对多种压力源及其影响进行全面、综合的评估。该项目将通过5所大学培训至少26个HQP职位，包括15名URA、4名硕士、4名博士、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河流设施和河流测量来确定 ESOC 的环境命运，检测与食物网相关的关注变化，并确定敏感的生理和微生物工具来检测早期反应并确定 MWWE 的暴露程度。与土著社区的关键关系将确定未来研究阶段设计和结构的优先问题和关注领域。设计和完善针对最大排放源（按数量计算）的监测方法，有助于生成能够对全加拿大产生影响和应用的知识、工具和解决方案。
