contamination

This is a guest post by Evangeline Lilly, Canadian actress.

For those of you who don’t know me, I am a Canadian actress who has been living abroad in Hawaii for the past ten years. I have been involved in such well-known projects as the television series “Lost”, the indie hit “The Hurt Locker”, the blockbuster film “Real Steel” and the upcoming second and third “Hobbit” films.

Companies responsible for two separate oil spills in Alberta failed to provide adequate oversight for their operations, according to federal government documents released by Environment Canada through Access to Information legislation.

The documents detail how Devon Canada and Gibson Energy violated environmental laws, including the federal Fisheries Act, when their operations cause two oil spills into fish-bearing waterways in 2010.

Gibson Energy, a midstream pipeline operator, spilled a few hundred litres of oil into an Edmonton creek after failing to properly abandon an unused pipeline. According to a warning letter issued to the company from Environment Canada, "Gibson Energy ULC made a business decision to keep the Kinder Morgan lateral full of crude oil and to not purge it with nitrogen."

Today federal scientists from Environment Canada presented research at an international toxicology conference in the U.S. that indicates contaminants from the Alberta tar sands are polluting the landscape on a scale much larger than previously thought.

A team lead by federal scientist Jane Kirk discovered contaminants in lakes as far as 100 kilometers away from tar sands operations. The federal research confirms and expands upon the hotly contested findings of aquatic scientist David Schindler who, in 2010, found pollution from the tar sands accumulating on the landscape up to 50 kilometers away.

"That means the footprint is four times bigger than we found," Schindler told Postmedia News.

Senior scientist Derek Muir, who presented some of the findings at Wednesday's conference, said the contaminated region is "potentially larger than we might have anticipated." The 'legacy' of chemicals in lake sediment gives evidence that tar sands pollution has been traveling long distances for decades. Samples show the build up of polycyclic aromatic hydrocarbons, or PAHs, known to cause cancer in humans and to be toxic to aquatic animals, in 6 remote and undisturbed lakes up to 100 kilometers away from tar sands operations.

The pollutants are "petrogenic" in nature, meaning they are petroleum derived, and have steadily and dramatically increased since the 1970s, showing the contaminant levels "seem to parallel the development of the oilsands industry," Muir said.
