Seven things you should know about blue-green algae

Green layer of scum on Jones Lake in Moncton not toxic, city says

Much of the surface of Jones Lake in Moncton's west end is covered by a thick, green layer of scum. The city has determined it's "horse hair" algae, also known as "cotton ball" algae. Dan Hicks, the director of parks for the city, says it might not look good, but it isn't toxic to people or pets. "It doesn't cause really human health issues in any great way, but there's certainly an abundance of it in Jones Lake right now," he said.
