Not exactly a neutral source. The one measure cited that is the really appropriate one is that the levels are 'above' average. Since they did not bother to say how much above average, I would guess that it is not much (the dog that did not bark).
Can you get something from other than the NG industry or the dug-in foes of fracking for reliable information (the first report really has nothing that you can rely on; it might be true or it might not, and it might not be nearly as relevant as they make it sound.
