Increasing contaminant loads to the environment and recent warmer and longer summers/fall seasons are affecting the concentration and composition Natural Organic Mater (NOM), especially in algae impacted raw water sources. NOM is of importance because it can lead to the formation of Disinfection By-Products (DBPs) of concern and can negatively impact the performance of water treatment processes. Some algae derived NOM can also lead to taste, odor and toxicity problems. Combined with increasing water demands, these stressors have forced many communities to increasing rely on water sources that are of poorer quality and/or located remotely. Although it is possible with 'advanced' technologies to produce and convey high quality drinking water to consumers from these sources, the cost of doing so is as much as 20 times more than that from pristine/local sources. Therefore for many Canadian communities, especially for small and remote communities that do not have the financial and technical resources to implement the needed technologies, it is becoming increasingly difficult to provide high quality drinking water. This is of particular importance in Canada where water systems in small and remote communities account for over 75% of all water entities. The overall objective of the research program is to enable Canadian communities to provide high quality drinking water to consumers from algae impacted raw waters. Three intermediate objectives are proposed to address the overall research objective: 1) characterize NOM in algae impacted waters, 2) assess the fate and biodegradation of NOM in algae impacted waters, and 3) develop a simple approach to treat water from algae impacted sources.

环境中污染物负荷的增加以及最近更温暖和更长的夏季/秋季正在影响天然有机物质(NOM)的浓度和组成，特别是在受藻类影响的原始水源中。NOM很重要，因为它可能导致令人关注的消毒副产品(DBPs)的形成，并可能对水处理过程的性能产生负面影响。一些藻类衍生的NOM还会导致味道、气味和毒性问题。再加上不断增加的用水需求，这些压力迫使许多社区越来越依赖水质较差和/或地处偏远的水源。虽然利用“先进”技术可以生产高质量的饮用水，并从这些来源向消费者输送高质量的饮用水，但这样做的成本是原始/本地来源的20倍。因此，对于许多加拿大社区来说，特别是对于没有资金和技术资源来实施所需技术的小型和偏远社区来说，提供高质量的饮用水变得越来越困难。这在加拿大尤为重要，加拿大小型和偏远社区的供水系统占所有供水实体的75%以上。该研究计划的总体目标是使加拿大社区能够从受藻类影响的原水向消费者提供高质量的饮用水。提出了三个中间目标来解决整个研究目标：1)表征受藻类影响的水体中的NOM，2)评估NOM在受藻类影响的水域中的去向和生物降解，以及3)开发一种简单的方法来处理受藻类影响的水源水。
