DEP inspections show more shale well cement problems
But violations data released last week by the state Department of Environmental Protection show problems persist with the cemented strings of steel casing meant to protect groundwater from gas and fluids in Marcellus wells.
In August, DEP inspectors found defective or inadequate casing or cement at eight Marcellus wells, including Hess Corp.'s Davidson well in Scott Twp., Wayne County - the first casing violation found in the county where only a handful of Marcellus wells have been drilled.
