UNDATED (AP) — Pennsylvania Gov. Tom Wolf says his administration will spend $3 million on a pair of studies to explore the potential health effects of the natural gas industry. Wolf is taking action after months of impassioned pleas by the families of pediatric cancer patients who live in the most heavily drilled region of the state. Dozens of children and young adults have been diagnosed with Ewing sarcoma and other forms of cancer in a four-county area near Pittsburgh.
