For years, fishing guide Rod Bates has been taking families out on the Susquehanna River in Pennsylvania and letting kids swim and play in the water. Then he learned about something disturbing being piped into the river from the Governor's Mansion and State Office Complex in Harrisburg, the state capital. The Environmental Integrity Project and Lower Susquehanna Riverkeeper investigated the outfalls. We discovered information that -- when released at a packed press conference -- sparked an interstate furor and demands for an investigation.
