The Delaware Riverkeeper Network on Monday launched an ad campaign to counteract what it called the Marcellus Shale industry's "well-financed promotion of natural gas."

Maya van Rossum, the Delaware Riverkeeper, said the industry's claims of natural gas as "a panacea that will fulfill America's energy needs, solve global warming and make us independent from foreign oil" would be exposed as "hog wash."

The nonprofit has budgeted $55,000 for one month to lease two billboards and post placards on three subway platforms and 30 buses, said Tracy Carluccio, the network's deputy director.    - Andrew Maykuth
