The biggest of the Great Lakes and one of the largest freshwater ecosystems in the world — has remained relatively pristine compared to the other four. It’s far enough away from the populated urban centres in southern Ontario, its watersheds are largely forested, there’s little industry or agriculture on its shorelines and its especially cold water (an average of 4 C year-round) has kept away invasive species.
How microbes could help clean up Nova Scotia's abandoned mines
Researchers from three Maritime universities are hoping microbes collected from the bottom of a lake near an abandoned gold mine in Dartmouth, N.S., will provide a model for how to clean up contaminated sites across the province in a quicker and less-intrusive way. Last May, a research team took a boat to the middle of Lake Charles, not far from the former Montague gold mine, where extensive mining took place from 1860 to about 1940.
