The Star-Tribune is reporting on another recent study finding no link between E&P operations and groundwater contamination claims: "Natural gas operations are not linked to groundwater contamination in the Pinedale area, according to a new Bureau of Land Management report. *** The report, released Wednesday, said low levels of hydrocarbons detected in groundwater wells in what's known as the Pinedale Anticline Production Area were largely attributable to natural processes. It found there was no widespread evidence linking those chemicals to spills, leaks or other byproducts of natural gas development. And it concluded no further mitigation efforts were needed to address water pollution in the area."
