The argument against natural gas got a boost this week, when a congressional investigation turned up evidence that oil and gas companies were using diesel gas to extract gas from the ground.
Natural gas companies have insisted that their newly popular hydraulic fracturing (known as “fracking”) techniques are safe, but as Care2’s Kristina Chew reports, “environmentalists and regulators have become increasingly concerned that the fracking chemicals—including toluene, xylene and benzene, a carcinogen, which are all from diesel gas—are seeping out into underground sources of drinking water, in violation of the Safe Water Drinking Act.”
The mix-up
The Environmental Protection Agency is conducting an inquiry into the environmental impacts of fracking, and some states are considering more stringent regulations of the practice, including disclosure of the chemicals that go into fracking fluid. Gas companies have argued that the blend of chemicals is a trade secret and must be kept private, but the findings of the congressional investigation suggest otherwise. Eartha Jane Melzer reports at The Michigan Messenger, “In a letter to EPA administrator Lisa Jackson… Reps. Henry Waxman, Edward Markey and Diana DeGette reported that although the EPA requires permits for hydraulic fracturing that involves diesel none of the companies that admitted using diesel have sought or received permits.”
And, as Melzer reports, diesel is the only chemical used in fracking that’s currently regulated under the Safe Drinking Water Act. That companies have been sneaking it into the ground does not strengthen the industry’s case for independence.
