DONEGAL TWP — The state Department of Environmental Protection hasn't pinpointed the source of a flammable gas that burned a township man when he turned on a well water pump.

DEP spokeswoman Freda Tarbell says there are no permitted natural gas wells in the area where 33-year-old Paul Edwards was burned Sunday afternoon.

She says a utility company has lines in the area, but so far no leaks have been found. Sometimes, Tarbell says, natural gases from the earth simply gather in such wells, though it's not clear if that happened in this instance.

Edwards says he was burned Sunday afternoon after he flipped an electrical switch at the well near a camping area. He's being treated for second-degree burns in a Pittsburgh hospital.
