Natural gas companies have already started to hydrofrack in some areas of the Marcellus Shale. But in New York state, pending legislation could halt the process.
State Sen. Joseph P. Addabbo Jr., D-Howard Beach, is sponsoring a bill that calls for a moratorium upon hydraulic fracturing until 120 days after the EPA releases a new study regarding water quality and public health.
The next EPA study is expected to come out in December 2012.
"It's only common sense to stop it for awhile and really do a thorough investigation," said Fox, who backs the bill. "There's just too many people suffering."
After his screenings, Fox asked audiences to contact lawmakers and urge them to support the Addabbo Bill.
"You have to realize that New York can actually lead this charge and be this force of sanity," Fox told crowd in Syracuse, N.Y., to applause.
One audience member, Judith Fancher, left the "Gasland" screening feeling informed, yet afraid.
"I was aware of [hydrofracking] going on," she said, "but I had no idea about the extent of it. It really shook me all the way down my spine."
