Results from recent water tests in the Belleisle Bay reveal abnormally high levels of E. coli. When tested in late September, the Belleisle Watershed Coalition determined E. coli levels in the bay were an average 257 per 100 millilitres of water. That's 367 times higher than the average level of 0.7 E. coli per 100 millilitres detected in August. Some of these levels exceed what Health Canada considers to be safe for recreation, which for the measuring technique used, is less than 200 per 100 millilitres of water. In drinking water, Health Canada recommends no detectable E. coli.
