Tweaking The Fracking Process To Prevent Environmental Damage

Men with Cabot Oil and Gas work on a natural gas valve at a hydraulic fracturing site in South Montrose, Penn. Hydraulic fracturing, also known as fracking, stimulates gas production by injecting wells with high volumes of chemical-laced water in order to free up pockets of natural gas below.

It's Not Fracking's Fault, Study Says -- MSNBC

A university study asserts that the problems caused by the gas extraction process known as hydraulic fracturing, or "fracking," arise because drilling operations aren't doing it right. The process itself isn't to blame, according to the study, released today by the Energy Institute at the University of Texas at Austin.

The report is likely to add new fuel to a blazing controversy over fracking. Researchers reviewed the evidence contained in the reports of groundwater contamination from three prominent shale-rock formations where the process is employed: the Barnett Shale in North Texas, the Marcellus Shale in Pennsylvania, New York and other areas of Appalachia; and the Haynesville Shale in western Louisiana and northeast Texas.
