Across the street from the convention center, demonstrators collect bottled water and donations to help families whose drinking water, they say, has been contaminated by fracking along the Marcellus Shale in central and western Pennsylvania.
“Many well owners and families in the places where the drilling is occurring have experienced contamination of their water wells because of gas drilling,” says Tracy Carluccio of the Delaware Riverkeeper Network, also with the group Shale Gas Outrage.
Steve Forde, a spokesman for the Marcellus Shale Coalition, says studies show fracking does not harm groundwater. He says the protesters are wrong.READ MORE: Double Shooting In Eastwick Kills 25-Year-Old Man, Wounds Pregnant Woman: Police
“We respect their right to assist communities that they feel might be in need. I think the water drive may have more to do with optics for television cameras than it actually does with facts,” Forde said.
The conference wraps up Thursday with a keynote speech from former US House speaker Newt Gingrich.MORE NEWS: 'I Want To Go To Class': Philadelphia Students, Parents On Edge As Possible SEPTA Strike Could Force Virtual Learning
