A natural gas boom is underway in America, but how safe is the extraction process known as fracking?

So vast is the wealth of natural gas locked into dense rock deep beneath Pennsylvania, New York, West Virginia and Ohio that some geologists estimate it's enough to supply the entire East Coast for 50 years. (AP)
In a time of energy uncertainty and scarcity, nearly a quarter of American power now comes from natural gas.
And more and more of that gas is produced by hydraulic fracturing, or “fracking.”
High-pressure facturing, deep underground. Fracking is a boon to production. And fracking is a hot button issue, with opponents charging frightening environmental damage.
We’ve come to the edge of fracking country today, to look at the latest science and at community response to a huge energy push.
This hour On Point: on the edge of the Marcellus Shale, we’re looking at “fracking.”
