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《清洁水法》（2006年）出台以来，水源保护已成为城市地下水管理计划的一个组成部分。这项立法的目的是通过协作性的、以科学为基础的水源保护计划来保护现有和未来的饮用水源，这些计划确定并减轻对当地供水的潜在威胁。然而，气候和土地利用变化、人口增长和社会经济压力可能会导致地下水可持续利用的重大不确定性。这些不确定性激发了一个部支持的审查安大略的水量管理框架。该提案旨在通过开发和验证高分辨率地下水特征描述和监测基础设施，并通过直接支持和加强市政地下水保护计划的强有力的科学协议，推进有冰川沉积物覆盖的断裂沉积基岩含水层的水源保护和水资源管理战略。先进的表征和监测技术，特别是适用于高度异质性的沉积物（<150米深），将通过系统的同化到现有的和同时先进的区域地下水流模型，在五个相互关联的城市依赖于共享志留纪白云岩含水层传统收集的数据集进行评估。拟议的研究将采用多学科的方法来了解区域地质构造，地下水流路径和地下水-地表水相互作用，其规模与井口保护区划定，土地利用监测和城市规划有关。这项研究的结果将提供不断增长的安大略社区，负责管理动态相互依赖的生态/水文系统内的共享地下水资源，以科学为基础的工具箱，以更好地了解他们的地下水资源，从而使数据知情的地下水监测网络的发展。这些活动将支持以科学为基础的地下水管理政策，以确保加拿大不断扩大的社区获得安全和可持续的饮用水。
