Blue-Green Algae detected in Lake Rosalind, Hanover
Results from a sample taken on July 11 by the Ministry of the Environment and Climate Change show the presence of a blue green algae bloom in Lake Rosalind. Additional testing is underway to determine concentrations.
As some types of blue-green algae can produce toxins, Public Health us advising caution around the use of Lake Rosalind and the interconnected Marl Lake. Residents using these lakes for drinking water should be aware that typical domestic treatment does not provide significant protection from blue-green algae or their toxins. Boiling water is also ineffective at reducing the toxin and may in fact increase it. The use of alternative water supplies is recommended until more information is available on the levels of toxin in the lakes. In addition, the water should not be used for bathing or swimming and that pets be prevented from entering the water, particularly where the bloom is visible. Public Health continues to work with the Ministry and local residents groups on this issue.
Contact Public Health if you have any questions about this advisory. Contact the Ministry of the Environment and Climate Change Spills Action Centre at 1-800-268-6060, if further blooms are noted.
