The Province of Ontario has recently recognized the critical importance of effective source water protection measures to safeguard public health and environmental health (e.g. the Clean Water Act, which addresses some of the recommendations of the Walkerton Inquiry report). At the same time, it must also be recognized that innovations in wastewater and environmental contaminant treatment systems (for the design and operation of effective, cost efficient and operationally simple enhanced passive systems) are still required, to allow for source water protection in all areas of the province, particularly in the smaller semi-urbanized and rural areas lacking the resources to implement high technology "urban" style water and wastewater management infrastructure and processes. In order to be able to propose such innovative enhanced passive systems, a basic scientific and engineering understanding of these systems must first be gained, and this is best done through the long-term operation and assessment of full-scale field demonstration systems.The proposed research program will build on significant previous successes, in terms of the establishment of a substantial network of field research sites, and their use in the detailed assessment of system and process operation and design in cold-climate settings. Systems to be evaluated include a subsurface flow constructed wetland for the treatment of diffuse landfill leachate (Kingston ON), an innovative near zero-discharge vegetated filter (the Wastewater Garden), for the on-site treatment of domestic wastewater (Portland ON), and an enhanced subsurface wastewater disposal trench process using an innovative filtration medium for improved treatment (Cornwall ON). These processes are representative of the family of passive (operationally and mechanically simple) systems, but they also represent appropriate technologies for source water protection, once we have achieved a thorough understanding of the chemical, physical and biological processes at work through detailed field investigations. This information in turn will allow regulators to make informed decisions about the application of these systems in Ontario and across Canada.

安大略省省最近认识到有效的源防水措施以保护公共卫生和环境健康的重要性（例如《清洁水法》，涉及Walkerton查询报告的一些建议）。同时，还必须认识到，仍然需要废水和环境污染物的治疗系统（用于设计和运行有效，具有成本效益和操作的简单增强的被动系统）的创新，以便在所有领域提供源防水该省，特别是在较小的半城市化和农村地区，缺乏实施高科技“城市”风格的水和废水管理基础设施和流程的资源。为了能够提出这种创新的增强的被动系统，必须首先获得对这些系统的基本科学和工程理解，这是通过长期操作和评估全尺度现场演示系统的评估。研究计划将基于以前的取得重大成功，建立大量的现场研究站点网络，以及它们在寒冷气候环境中对系统和过程操作和设计的详细评估中的使用。要评估的系统包括用于治疗弥漫性垃圾填埋液（Kingston on）的地下流量，这是一种零离职植被过滤器（废水花园）的创新性，用于现场处理家庭废水（波特兰）的现场处理，并使用创新的过滤培养基改进治疗（ON CORNWALL），增强了地下废水处理沟槽工艺。这些过程代表了被动（操作和机械上简单）系统的家族，但一旦我们通过详细的现场调查对工作中的化学，物理和生物学过程有了彻底的了解，它们也代表了用于源防水的适当技术。这些信息反过来将使监管机构能够就这些系统在安大略省和整个加拿大的应用做出明智的决定。
