Stormwater and municipal effluents are important issues requiring action in response to new regulations and identified problems and health risks. In the fall of 2015, 90 000 individuals signed a petition requesting that the City of Montreal stop a raw sewage spill, that was planned in order to maintain its interceptor sewer. Through the numerous national and international media stories, Canadians learned that raw sewage spills are a common occurrence, with more than 45 000 occurring in 2013 in Quebec alone. There is growing public pressure for open and real time data on raw sewage spills, yet few data are available, including on the effects of such spills. The proposal addresses novel technologies for reducing threats to drinking water supplies from urban effluents, including raw sewage spills. The overall goal of this research is to validate novel solutions for protecting urban drinking water sources. The research project will: 1) fill in data and knowledge gaps for contaminant accumulation in sewer sediments that are needed for real-time control of combined sewers and, if unaddressed, could limit the use of new green infrastructure technologies for source water protection, 2) test new next generation sequencing methods for contaminant source identification and compare with more specific source tracking targets, 3) evaluate human enteric viruses as markers of human fecal contamination, and 4) determine how automated high frequency E. coli monitoring can be used to improve drinking water treatment plant design and operation using a promising new technology for continuous E. coli monitoring that has yet to be tested in Canadian waters. Exchanges among project participants will enable the rapid transfer of knowledge to end-users in Canada (e.g. municipalities, policy-makers and government laboratories). The involvement of Environment Ministries will facilitate the transfer of laboratory methods to these groups for more widespread application for water infrastructure decision-making. Highly qualified personnel working alongside our industrial partners will be trained in the areas of emerging environmental contaminants, green infrastructure, metagenomics, new automated technologies for water quality monitoring, and urban source water protection.

雨水和城市污水是重要的问题，需要采取行动，以应对新的法规和已查明的问题和健康风险。2015年秋天，9万人签署了一份请愿书，要求蒙特利尔市停止原污水泄漏，这是为了维护其拦截下水道而计划的。通过众多的国内和国际媒体报道，加拿大人了解到，未经处理的污水泄漏是一种常见的现象，仅在魁北克，2013年就发生了45 000多起。公众要求公开和真实的原始污水溢漏数据的压力越来越大，但可获得的数据很少，包括关于这种溢漏的影响的数据。该提案涉及减少城市污水（包括未经处理的污水泄漏）对饮用水供应的威胁的新技术。本研究的总体目标是验证保护城市饮用水源的新解决方案。该研究项目将：1）填补下水道沉积物中污染物积累的数据和知识空白，这是实时控制合流下水道所需的，如果不加以解决，可能会限制用于水源保护的新绿色基础设施技术的使用，2）测试用于污染物源识别的新的下一代测序方法，并与更具体的源跟踪目标进行比较，3）评估人类肠道病毒作为人类粪便污染的标志物，以及4）确定如何自动化高频E.大肠杆菌监测可用于改善饮用水处理厂的设计和操作，使用一种有前途的新技术，连续大肠杆菌。大肠杆菌监测，尚未在加拿大沃茨进行测试。项目参与者之间的交流将使知识能够迅速转让给加拿大的最终用户（例如市政当局、决策者和政府实验室）。环境部的参与将有助于向这些团体转让实验室方法，以便更广泛地应用于水基础设施的决策。与我们的工业合作伙伴一起工作的高素质人员将接受新兴环境污染物、绿色基础设施、宏基因组学、水质监测新自动化技术和城市水源保护等领域的培训。
