Mr. Smith, I can also cut and paste. This is a statement from the same EPA report you cited: The U.S. Environmental Protection Agency. August, 2002. DRAFT Evaluation of Impacts to Underground Sources of Drinking Water by Hydraulic Fracturing of Coalbed Methane Reservoirs. EPA 816-D-02-006:

"Based on the information collected and reviewed, EPA has concluded that the injection of hydraulic fracturing fluids into CBM wells poses little or no threat to USDWs and does not justify additional study at this time."

Just for the record the Barnett shale formation is neither limestone nor coalbed in nature. The Barnett shale formation also has adjacent geological barriers which have helped keep the natural gas from escaping for millions of years. And TxSharon, you should consider yourself very lucky that, in your neighbohood, water bubbles out of the ground from a mile down for your doggie to drink and your barefoot kids to run through.
