Geochemistry scientist on fracking: "The problem is going to get worse, not better"

Until recently, there have not been scientifically grounded independent investigations that seek to fully understand the role of fracking in most groundwater contamination incidents . One exception is the investigation of the groundwater contamination in Bainbridge Township, Ohio, where the state found that one of the contributing factors was: “the frac communicated directly with the well bore and was not confined within the “Clinton” reservoir.”
