Environmental groups from across the state are heading to Albany the morning of Monday, April 11 for a rally against high-volume hydraulic fracturing for natural gas in the Marcellus Shale region that spans the southern half of New York and parts of Pennsylvania, Ohio and West Virginia. The Hydro-Fracking Day of Action, according to Citizens Campaign for the Environment, begins with a 10:30 to 11:30 a.m. rally on the Capitol Lawn with activists and advocates from throughout New York; then a 12:30 to 3:30 p.m. series of visits to individual legislators to "educate New York's lawmakers about the dangers of dirty drilling." According to an Associated Press story on the rally found on the website for the Times Herald-Record, "opponents fear the technology commonly called 'fracking' may lead to contamination of water supplies. New York has had a moratorium on permits for high-volume fracking since it initiated a comprehensive environmental review of it nearly three years ago. Fracking involves the high-pressure injection of chemically treated water into a gas well to crack surrounding shale and release trapped natural gas. The industry says fracking is well-regulated and safe." Among the speakers at Monday morning's rally will be Josh Fox, director of the anti-gas industry documentary "Gasland," and actor Mark Ruffalo, who has recorded station welcomes for WGXC.
