Two young children in Pennsylvania were banned from talking about fracking for the rest of their lives under a gag order imposed under a settlement reached by their parents with ... a leading oil and gas driller. The settlement, reached in 2011 but unsealed only last week, barred the Hallowichs' son and daughter, who were then aged 10 and seven, from ever discussing fracking or the Marcellus Shale, a leading producer in America's shale gas boom. The Hallowich family had earlier accused oil and gas companies of destroying their 10-acre farm in Mount Pleasant, Pennsylvania and putting their children's health in danger. Their property was adjacent to major industrial operations ... which the Hallowich family said contaminated their water supply and caused burning eyes, sore throats and headaches. The family gag order was a condition of the settlement. The couple told the court they agreed because they wanted to move to a new home away from the gas fields, and to raise their children in a safer environment. We need to get the children out of there for their health and safety," the children's mother, Stephanie Hallowich, told the court. She was still troubled by the gag order, however. "I'm not quite sure I fully understand. We know we're signing for silence forever but ... my daughter is turning seven today, my son is 10." The court transcripts were released in response to an open records request by the Pittsburgh Post Gazette, which first reported on the children's lifetime gag order.
