Some of the findings in the report also directly contradict longstanding arguments by the drilling industry for why the fracking process is safe: that hydrologic pressure would naturally force fluids down, not up; that deep geologic layers provide a watertight barrier preventing the movement of chemicals towards the surface; and that the problems with the cement and steel barriers around gas wells aren't connected to fracking.

Then, in 2011, a congressional investigation found that in fact between 2005 and 2009, 12 companies had injected 32 million gallons of diesel fuel or fracking fluids containing diesel fuel in wells in 19 states.

But they also found that produced water contained potentially toxic chlorocarbons and organobromides, probably formed from interactions between high levels of bacteria in the water and salts or chemical treatments used in fracking fluids.
