WASHINGTON -- Millions of gallons of potentially hazardous chemicals and known carcinogens were injected into wells by leading oil and gas service companies from 2005-2009, a report by three House Democrats said Saturday.
The report said 29 of the chemicals injected were known-or-suspected human carcinogens. They either were regulated under the Safe Drinking Water Act as risks to human health or listed as hazardous air pollutants under the Clean Air Act.
Methanol was the most widely used chemical. The substance is a hazardous air pollutant and is on the candidate list for potential regulation under the Safe Drinking Water Act.
The report was issued by Reps. Henry Waxman of California, Edward Markey of Massachusetts and Diana DeGette of Colorado.
The chemicals are injected during hydraulic fracturing, a process used in combination with horizontal drilling to allow access to natural gas reserves previously considered uneconomical.
The report said that from 2005-2009, the following states had at least 100,000 gallons of hydraulic fracturing fluids containing a carcinogen: Texas, Colorado, Oklahoma, Louisiana, Wyoming, North Dakota, New Mexico, Montana and Utah.
States with 100,000 gallons or more of fluids containing a regulated chemical under the Safe Drinking Water Act were: Texas, New Mexico, Colorado, Oklahoma, Mississippi and North Dakota.
The report said many chemical components were listed as proprietary or trade secret.
