Innovative passive treatment systems for source water protection

安大略省最近认识到有效的水源保护措施对保障公众健康和环境健康至关重要（例如《清洁水法》，其中处理了沃克顿调查报告的一些建议）。同时，还必须认识到，废水和环境污染物处理系统（设计和操作有效、成本效益高和操作简单的增强型被动系统）仍然需要创新，以便在全省所有地区保护水源。特别是在较小的半城市化和农村地区，缺乏资源来实施高技术的“城市”式水和废水管理基础设施和流程。为了能够提出这种创新的增强型被动系统，必须首先获得对这些系统的基本科学和工程理解，而这最好通过对全尺寸现场演示系统的长期运行和评估来完成。

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.
