TOPIC: Water Quality Management
In the post-Walkerton era, public works officials and their consultants are yet again, faced with a biological threat to consider. Cyanobacteria (commonly referred to as blue-green algae) comprise a distinct category of bacteria that utilize photosynthesis for growth. During the warm summer months, cyanobacteria reproduce rapidly, forming significant "blooms" that become readily apparent throughout nutrient rich waters.
A potentially hazardous and often lethal consequence associated with blooms, is the production of microcystins, by several common species of cyanobacteria. Historically, these toxins have been linked to poisonings of livestock, pets and wildlife. Human illness attributable to microcystin exposure via drinking water is beginning to attract attention. This has prompted the World Health Organization and several countries, including Canada, to establish drinking water guidelines for microcystin.
Hydroqual Laboratories Ltd. conducted a study on behalf of Alberta Environment to determine the prevalence of microcystin in treated and untreated municipal water sources and to assess the adequacy of current water treatment in reducing toxin levels. Results suggest municipalities employing additional and sophisticated water treatment technologies may remove more microcystin than those relying on conventional methods only.
