From the artcle:

Just how did all that methane build up if not from natural-gas drilling? The “Gasland Correction Document” describes how methane ends up in well water. Two processes create what scientists call “biogenic gas.” One is the chemical reduction of carbon dioxide, and the other is breakdown of organic materials by bacteria. Biogenic gas contains “only methane and a very small amount of ethane.” This is an important distinction, because there is one more source of subterranean methane, “thermogenic gas.”

The latter requires heat and pressure only found in rock formations much deeper within the Earth. Thermogenic gas “contains not just methane and ethane but also heavier hydrocarbons such as propane, butane, pentane and hexanes.” Fracing drills for thermogenic gas trapped in shale deposits located 5,000 or more feet below the surface, while water tables are rarely deeper than 400 feet. The document goes on to say: “Gasland incorrectly attributes several cases of water well contamination in Colorado to oil and gas development when our investigations determined that the wells in question contained biogenic methane that is not attributable to such development.”

Here's a 14 minute piece made up of clips from Fracknation... http://www.youtube.com/watch?v=B03IYdHpvAM It's a very well done piece.

Anyone who spells it “fracking” is a journalist. It is fracing, which is short for fracturing. No one in the industry spells it that way.
