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.

环境污染物负荷的增加以及近年来夏季和秋季的变暖和变长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水水源中。NOM很重要，因为它会导致引起关注的消毒副产物（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也会导致味道、气味和毒性问题。再加上不断增加的用水需求，这些压力因素迫使许多社区越来越依赖质量较差和/或位于偏远地区的水源。虽然利用“先进”技术可以从这些水源生产和输送高质量的饮用水给消费者，但这样做的成本比从原始/当地水源生产和输送高20倍。因此，对于许多加拿大社区来说，特别是对于那些没有财政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。这在加拿大尤其重要，因为加拿大小型和偏远社区的水系统占所有水实体的75%以上。
