Description

Microcystin, a widespread hepatotoxin, has been the topic of recent research in Alberta and it is suspected that certain communities may be exposed to this toxin because elevated levels have been measured in their raw water supplies. However, the total extent of microcystin in Alberta’s raw drinking water sources remains largely undetermined. Furthermore, it is unclear whether traditional drinking water treatment practices effectively remove microcystin. The objectives of this study were: to assess the prevalence of microcystin in selected municipal raw water sources; to determine if current water treatment practices adequately remove the toxin; and to determine the efficacy of an experimental bio-filtration process for the removal of microcystin.

A review of epilithic algal biomass, nutrient, and nonfilterable residue data for major Alberta river basins

Description

The objectives of this review were to describe the river course variation of benthic algal biomass, nutrient and nonfilterable residue variables and their interrelationships in Alberta rivers.... More ≫

Description

The objectives of this review were to describe the river course variation of benthic algal biomass, nutrient and nonfilterable residue variables and their interrelationships in Alberta rivers. Trends in these variables were compared between river basins, and the physiographic zones and ecoregions through which these rivers flowed were also documented.
