Source water protection has become an integral component municipal groundwater management plan since the introduction of the Clean Water Act (2006). The purpose of this legislation is to protect existing and future sources of drinking water, through collaborative science-based source water protection plans that identify and mitigate potential threats to local water supplies. However, significant uncertainties in sustainable groundwater use may arise through climate and land use changes, population growth, and socioeconomic stresses. These uncertainties have inspired a Ministry-supported review of Ontario's water quantity management framework. This proposal aims to advance source water protection and water resource management strategies in fractured sedimentary bedrock aquifers with overlying glacial sediments, through the development and validation of high-resolution groundwater characterization and monitoring infrastructure, augmented by robust scientific protocols that directly support and enhance municipal groundwater protection plans. Advanced characterization and monitoring techniques, specifically adapted to highly heterogeneous sediments (<150 m deep), will be evaluated against conventionally collected data sets through systematic assimilation into existing and concurrently-advanced regional groundwater flow models across five interconnected municipalities reliant on a shared Silurian dolostone aquifer. The proposed research will adopt a multi-disciplinary approach to understand regional geologic formations, groundwater flow paths, and groundwater-surface water interactions at scales relevant to wellhead protection area delineation, land-use monitoring, and urban planning. The results of this research will provide growing Ontario communities, tasked with managing a shared groundwater resource within dynamic inter-dependent ecologic/hydrologic systems, with a scientific-based toolbox to better understand their groundwater resource, thereby enabling the development of data-informed groundwater monitoring networks. These activities will support science-based groundwater management policies that ensure safe and sustainable drinking water for growing Canadian communities.

自从《清洁水法》（2006年）引入自《清洁水法》（2006年）引入以来，源防水已成为不可或缺的市政地下水管理计划。这项立法的目的是通过基于合作的科学水上保护计划来保护现有的和未来的饮用水来源，以识别和减轻对当地供水的潜在威胁。但是，可持续地下水使用的明显不确定性可能是通过气候和土地使用变化，人口增长和社会经济压力而产生的。这些不确定性启发了对安大略省水量管理框架的受政府支持的评论。该提案旨在通过开发和验证高分辨率的地下水表征和监测基础设施，通过良好的科学协议增强，通过开发和验证高分辨率的地下水表征和监测基础设施，从而推进了带有覆盖冰川沉积物的破碎的沉积基岩含水层中的水资源和水资源管理策略，从而直接支持和增强了市政地下水保护计划。先进的表征和监测技术，特别适合于高度异质的沉积物（深度<150 m），将通过系统地同化在五个共享silurian silurian dolostone Aquiferiant依赖于五个相互联系的城市中的现有和同时增强的区域地下水流程模型来评估常规收集的数据集。拟议的研究将采用一种多学科的方法来了解与井口保护区划定，土地使用监测和城市规划相关的尺度上的区域地质形态，地下水流动路径和地下水面水相互作用。这项研究的结果将为不断增长的安大略省社区提供，其任务是在动态相互依存的生态/水文系统中管理共享的地下水资源，并提供基于科学的工具箱，以更好地了解其地下水资源，从而促进了数据信息中的地下水监测网络的发展。这些活动将支持基于科学的地下水管理政策，以确保为成长中的加拿大社区提供安全可持续的饮用水。
