WASHINGTON — Colorado ranked second only to Texas in terms of the number of gallons of carcinogen-laced "fracking" fluids used in oil and gas extraction between 2005 and 2009, according to congressional Democrats.
A 30-page House Energy and Commerce report — the second release in an investigation into hydraulic fracturing — shows that 1.5 million gallons of fracking fluids containing a carcinogen were used in Colorado in that time, compared with 3.8 million gallons in Texas and 1 million in Oklahoma. The report does not show the concentrations of those chemicals or that the carcinogens, including naphthalene and benzene, have endangered drinking water near the drilling sites in Colorado.
State leaders charged with regulating Colorado's energy industry say the report's findings are not a surprise.
"Generally, we know what kinds of chemicals are in frack fluids," said Dave Neslin, director of the Colorado Oil and Gas Conservation Commission. "We're still looking at it (the report). But from a high level, we know what they are and how they're used and how they're used in other parts of our lives.".....continued.....
