So I knew the answer when I saw this headline: "Does Natural-Gas Drilling Endanger Water Supplies? A debate is heating up over whether the fracturing technique used in natural-gas drilling could result in chemicals contaminating drinking water"
Here's a good excerpt (but read the whole story):
A close look at the EPA's 2004 study reveals that the agency may have played down evidence of health dangers. And now some regional EPA officials say it's time for the industry to disclose precisely what it's pumping into the ground.Since Halliburton loves kitties, I know that they are not doing anything wrong, so I guess that my initial idea is incorrect. :)
Energy companies are taking a tough stance. Last summer, Houston-based Halliburton threatened to cease natural-gas operations in Colorado if regulators there persisted in demanding the chemical recipe used in a common drilling process known as hydraulic fracturing.
Speaking of nice people, this article points out how agricultural runoff is causing about $4 billion/year in damages to freshwater supplies. (Thank god for ethanol!)
Speaking of ethanol, it looks like the Indy 500 will be run on Brazilian ethanol (!), because (?) "...the economics of [American] corn-based ethanol right now are terrible. Brazilian sugarcane ethanol is cheaper to make (and most studies say it is also more environmentally-friendly), but imports into the U.S. face a stiff tariff."
Bottom Line: Water quality regulations mean nothing unless they are enforced.
