Business & Finance Club - Art & Culture - Films: Two months after the BP oil spill, it may be easy to hear the words "water contamination" and "drilling" and immediately think "Gulf Coast."

But one filmmaker says there's another water source at risk -- and this one is in our own backyards.

In his new film, "Gasland," filmmaker Josh Fox spotlights the practice of hydraulic fracturing, or hydrofracking, a process that extracts natural gas from rock formations.

He started his film after a gas company offered him nearly $100,000 for the rights to drill for natural gas on his property  in the Delaware River Basin, along the New York-Pennsylvania border.

Instead of accepting, Fox began investigating.

 His documentary premiered on HBO on Monday night and highlighted what Fox claims are the direct results of hydraulic fracturing: water contamination, well failures and health problems for people living near the wells.

HBO will be replaying the documentary later this month and next month.

The film explains hydraulic fracturing as a "mini earthquake." Gas companies insert a horizontal pipe several thousand feet below the ground and blast a "fracking fluid" to break up the rock and release natural gas.

 To tell the story, Fox -- whose property sits on the Marcellus Shale Field, a rock formation often called the Saudi Arabia of natural gas -- dubbed himself a "natural gas drilling detective." He traveled across the country with a camera, interviewing landowners who have entered into contracts with natural gas companies.
