Fracking Shale ... as waste storage?

A fellow named Russell Donnelly has been telling me for about a year

there is a secret motivation for fracking shale besides getting gas:

Industrial Waste disposal.

With this theory, suddenly many things make sense.

• Why would they frack so many wells when so few are profitable? 
• Where are all those chemicals coming from?
• At what cost for 80-100 tons of specialized chemicals per frack?
• There are only 2 corporations involved in fracking. There is no competition.
  So why all the secrecy around the "secret sauce"?
• Why are chemicals like acetone and methylene chloride showing up at well sites, when it has not been specifically or functionally (industrial solvent) been disclosed by FracFocus or any other industry source?

Remember: a large business unit of Halliburton is involved in Industrial Waste Disposal

Fracktracker has uncovered a document which bolsters this theory.

Some engineers are looking into using dry shale deposits as possible
sites for nuclear waste disposal. Check it:
