Making sure there is a supply of water and finding an economical method for disposing of the water used in fracking and production are major issues. Desalination can provide the fresh water and possibly could be used to recycle brackish water that comes from fracking and production. Based on some tentative calculations, it appears that this can be done economically.  The operators would pay for the work but be given some credit against the Oil & Gas severance tax/fee they currently pay.
