Energy companies have drilled thousands of natural gas wells in shale formations across Pennsylvania, Ohio and West Virginia. In our continuing series, we go beyond the drilling pads to explore pipelines and examine the health and environmental impacts that are being felt along the way.

This series was funded, in part, by the Park Foundation.
