Information About the Costs to the Alberta Environment from the Tar Sands

is extremely difficult to find.  I don't know how students in schools studying Geography and having to write a report can make sense from the statements issued in 2011.  It seems to me that what I really wanted to know is missing.  Questions like:

1.  How much water is used for the tar sands that is not part of the entire water use of Alberta.

2.  What is the air quality index in various monitoring stations?  Surely we have that technology.
