Brian Rahm of the state Water Resources Institute at Cornell University gave a presentation Tuesday at the David Howe Library, Wellsville, on the impact of Marcellus Shale drilling on water supplies.

WELLSVILLE — When Brian Rahm addresses the opposing views on hydrofracturing in the Marcellus Shale formation for natural gas, he says, “Neither side is particularly correct. The truth is somewhere in the middle.”

Mr. Rahm, of New York state’s Water Resources Institute at Cornell University, gave a presentation Tuesday evening on the potential impact of drilling in the Marcellus Shale on the region’s water supply. The presentation was at the David Howe Library.

Mr. Rahm said the Water Resources Institute tries to steer clear of the politics surrounding the issue, while focusing on the data regarding the impact on water resources. He said a framework for assessing these include planned and unplanned impacts on surface and subsurface areas.
