State Journal Article Describes UIC Disposal for Marcellus Wells.

Natural gas wells that are fracked using water and chemicals produce large amounts of water waste called flowback. Contrary to what many people believe, that water is not discharged into state streams. It is either treated and recovered, through processes such as AOP Clearwater is using in Fairmont, or it is put down an underground injection control (UIC) well. There's an article in the State Journal today by Pam Kasey that identifies places the UIC wells are located, and how it all works.
