Management, protection, and rehabilitation of freshwater ecosystems are central environmental concerns on a global scale. In particular, water managers must deal with rapid urban development and their associated negative consequences on water bodies. This multi-disciplinary project is built around four research axes that all aim at providing urban water managers with additional tools to better monitor and conserve aquatic ecosystems, with a particular focus on urban environments. The purpose of Axis 1 is to develop a watershed-scale assessment of drinking water supply vulnerability by coupling biomonitoring data (algae based) and human activity related risks. Simply stated, the aim of Axis 1 is to combine biological integrity data and land use information, at the watershed scale, to provide municipalities with a more complete portrait of water supply vulnerability. One significant threat to drinking water sources is urban stormwater runoff and Axes 2, 3, and 4 are designed to address this problem. Stormwater retention ponds (SWRPs) are a common mitigation practice to reduce urban runoff and Axis 2 aims to determine their positive outcomes (contaminant retention) and to evaluate the biological integrity of receiving environments upstream and downstream of their effluents. The objective of Axis 3 is to estimate the biodiversity in urban SWRPs, while the aim of Axis 4 is to estimate the monetary value, in dollars, of ecosystem services provided by SWRPs. Ultimately, the goal of this project is to provide an assessment of the benefits that constructed green infrastructures provide to taxpayers, which could then be used as a tool in economic, social, political, and ecological discourse and decision-making. Better management of stormwater runoff is one key aspect of drinking water source protection. The proposed research program will lead to the training of four Master's students, two undergraduate trainees, and one technician.

在全球范围内，淡水生态系统的管理，保护和康复是核心环境问题。特别是，水管理人员必须处理快速的城市发展及其对水体的负面影响。这个多学科项目围绕四个研究轴建立，旨在为城市水管理人员提供其他工具，以更好地监控和保护水生生态系统，特别关注城市环境。 Axis 1的目的是通过耦合生物监测数据（基于藻类）和与人类活动相关的风险来开发饮用水供应脆弱性的流域规模评估。简而言之，AXIS 1的目的是将生物完整性数据和土地使用信息结合在一起，以分水岭的规模为城市提供更完整的供水脆弱性肖像。饮用水源的一个重大威胁是城市雨水径流，轴2、3和4旨在解决这个问题。雨水保留池（SWRP）是减少城市径流的常见方法，Axis 2旨在确定其积极的结果（污染物保留），并评估其废水上游和下游接收环境的生物完整性。 Axis 3的目的是估计城市SWRP中的生物多样性，而Axis 4的目的是估算SWRP提供的生态系统服务的货币价值。最终，该项目的目的是评估建造绿色基础设施为纳税人提供的收益，然后将其用作经济，社会，政治和生态论述和决策的工具。更好地管理雨水径流是饮用水源保护的一个关键方面。拟议的研究计划将导致对四名硕士学生，两名本科学员和一名技术人员进行培训。
