Innovative passive treatment systems for source water protection

安大略省最近认识到采取有效的水源保护措施以保障公众健康和环境健康的极端重要性(例如，《清洁水法》处理了沃克顿调查报告中的一些建议)。与此同时，还必须认识到，仍然需要对废水和环境污染物处理系统进行创新(设计和运行有效、成本效益高、操作简单的增强型无源系统)，以便在该省所有地区保护水源，特别是在缺乏资源实施高科技“城市”式水和废水管理基础设施和流程的较小的半城市化和农村地区。为了能够提出这种创新的增强型无源系统，首先必须对这些系统有基本的科学和工程上的了解，这最好是通过全面实地示范系统的长期运行和评估来实现的。

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.
