Tar sands oil and Keystone XL's dirty secret

Politics run everything in the world. All of the publicity from Keystone XL is saying that the tar sands oil does not require extensive money to be cleaned up in the instance of a spill. One spill in particular has proven this false by what happened. The oil sands spill in the Kalamazoo River completely destroyed the river and cost $700 million to clean. The contractor for environmental risks is also biased in that he is strictly working for Keystone XL in Canada. The pipeline that is proposed to run from Canada to the Gulf Coast crosses the Ogallala aquifer, which provides water to many farmers and residents in the mid west of the United States. The oil that will travel through these pipelines is heavily corrosive and bound to cause problems. The gas line will allow for exports of oil out of the United States but would raise oil prices within the Nation. It seems that every piece of information that is revealed points further and further away from allowing this pipeline to go under construction.
