The Northwestern Health Unit is warning residents of two possible blue-green algae blooms, one in Wabigoon Lake and another in Abram Lake, near Sioux Lookout.
Water samples from a suspected bloom north of Frog Rapids in Abram Lake is being tested by the Ministry of Environment, Conservation and Parks, the health unit said.
Until results are known, residents should treat the new bloom as though it is blue-green algae: people and pets should avoid drinking, swimming or bathing in it or using it for other household purposes. Boiling water does not remove the toxins.
The health unit also received a report of an algae bloom in the Bonny Bay Road area of Wabigoon Lake.
Blue-green algae or cyanobacteria, which can be harmful to people and animals, had previously been confirmed to be present on the north end of the lake. That means the province won’t take samples of the newest bloom, the health unit said.
Residents there should also treat water as if blue-green algae is present, and avoid consumption, the health unit said.
Residential water treatment systems may not remove toxins and shouldn’t be relied on during a bloom, while municipally treated water can be used normally unless directed otherwise.
If contact with water does occur, wash with soap and water or rinse thoroughly with clean water, the health unit advised. It is recommended to wait at least two weeks after the bloom has disappeared before resuming normal use.
Residents can report suspected blue-green algae blooms, which can give water an appearance similar to turquoise paint or pea soup, by calling 1-866-663-8477.
