Face-Off Over 'Fracking': Water Battle Brews On Hill

Environmentalists and the natural gas industry are getting ready for a battle in Congress over something known as "hydraulic fracturing."
"Fracking," as the industry calls it, involves injecting a million gallons or more of water and chemicals deep underground to pry out gas that's locked away in tight spaces.
Environmentalists want the federal government to regulate the practice because, in some cases, fracking may be harming nearby water wells. The industry says regulation should be left up to the states.
Hydraulic fracturing allows drillers to dramatically increase production. The chemicals pumped underground with the water help drillers bore through the hard rock. The pressure used is tremendous — about 300 times a typical garden hose. That creates small cracks in the rock that allow gas to escape.
Steve Harris believes that pressure also ruined his well. He lives on 14 acres south of Dallas. Shortly after a driller fracked a nearby well, he and his neighbors noticed a change in water pressure.
"When you'd flush the toilet — in the back where the bowl is — water would shoot out the top of the bowl," says Harris.
When he took a shower, there was a foul odor, and the water left rashes on his grandson's skin. His horses stopped drinking from their trough, and there was an oily film on top of the water.
Similar stories are popping up around the country. In Ohio, a couple's house blew up when gas from their water well filled their basement. A woman in Colorado blames her health problems on the chemicals used for fracking.
For the most part, people nearby don't even know what chemicals are being injected into the ground — companies don't have to report that...
