Wyoming was one of 15 states in which oil and gas service companies injected hundreds of thousands of gallons of water containing potentially hazardous chemicals and known carcinogens into wells from 2005-2009, a report by three House Democrats said late last week.

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.

Wyoming ranked fourth among states with at least 100,000 gallons of water pumped containing a carcinogen in the four-year period, with a total volume of 759,898 gallons, according to the report. Texas ranked first with 3.88 million gallons.
