Government-funded study concludes toxic hydrocarbons from oilsands pollute lakes- CANADA

EDMONTON - New research has provided the most conclusive proof yet that oilsands development in northern Alberta is polluting surrounding lakes.

The findings all but end the debate over industry's contribution to toxins found in local watersheds, say the report's authors.

The federally funded research by some of Canada's top scientists was published Monday in the prestigious U.S. journal the Proceedings of the National Academy of Sciences. It concludes that levels of toxic hydrocarbons in six lakes in the oilsands region are between 2 1/2 and 23 times what they were before the mines were built.
