Do Not Use Water Advisory for Lake Rosalind – Lifted

As of 4:30 p.m., Monday, July 5, 2010 the Grey Bruce Health Unit lifted the Do Not Use Water Advisory for the residents near and around Lake Rosalind in the Municipality of Brockton. After consultation with the municipality, information about the advisory had been circulated to residents around Lake Rosalind and Marl Lake, which receives water from Lake Rosalind. Initial results from water sampling by the Ministry of the Environment on Wednesday, June 30 were free of blue green algae (cynobacteria). Results received this week show the samples had only trace levels of microcystins – below the maximum acceptable level for drinking water.  

Residents that use Lake Rosalind and Marl Lake are reminded that it is possible that the algae bloom will return this summer. The initial bloom was unusually early in the season and can reoccur at any time. It is recommended that residents continue to exercise caution using the lake. Residents should inform the Ministry of the Environment if they see indications of an algae bloom (turquoise or discoloured water, reduced water clarity or odours). In addition, the Ministry of the Environment will conduct routine sampling throughout the summer.
