Description

In 2002 Alberta Environment initiated several studies on Wabamun Lake in response to public concerns about murky water near the TransAlta Utilities Corporation ash lagoon outfall and to follow-up on incidences of fish mortality. Elevated metal levels were found in the water and sediments near the ash lagoon outfall, but the cause of fish mortality was unrelated to these metal levels. The objective of this study was to determine if the sediments contained substances toxic to aquatic life forms.
