Scientists are planning experimental "oil spills" in northwestern Ontario this summer in an effort to better understand what happens when diluted bitumen winds up in freshwater lakes.
In research with implications for how Canada regulates oil transport by pipelines and rail, ecologists at the Experimental Lakes Area (ELA) east of Kenora are planning to simulate a series of spills, clean them up and then assess what happens to the water, plants and animals.
