"Two academic studies exploring health and water issues in the gas drilling industry on Wednesday painted very different pictures of its potential impact and brought rebukes from advocates on both sides.

A Yale University survey supported by environmental groups including The Heinz Endowments found increased reporting of certain health issues by people who live within a kilometer of working wells in Washington County.

A Penn State University study funded by industry groups found that fracking water that remains deep underground after a well is finished will stay trapped in shale, far away from groundwater supplies."
