LYNDHURST – Tests have come back positive for toxic blue-green algae in Grippen Lake, southwest of Lyndhurst.
The algae bloom was spotted on Friday and the Leeds-Grenville and Lanark District Health Unit had been waiting on test results from the Ministry of Environment, which came back today.
“The presence of blue-green algae and its toxins was confirmed in Grippen Lake. Blue-green algae produce toxins that can cause skin irritation, nausea and vomiting, and in higher concentrations, liver problems as the algae cells break down,” the health unit said.
The toxins are not broken down by boiling water from the lake or using treatment methods like UV light or chlorine. The lake water should not be used for brushing your teeth, food preparation or for pets.
The health unit says you should also avoid swimming and water sports in the lake.
Residents should call the Spills Action Center at 1-800-268-6060v if they see any new blue-green algae blooms.
While the toxins will break down and be diluted in the lake over time, the amount of time will vary based on water movement in the area.
