What's in Fracking Fluid and Who's Telling The Truth?

The “surfactant” chemicals found in samples of fracking fluid collected in five states were no more toxic than substances commonly found in homes, according to a first-of-its-kind analysis by researchers at the University of Colorado Boulder.

Fracking fluid is largely comprised of water and sand, but oil and gas companies also add a variety of other chemicals, including anti-bacterial agents, corrosion inhibitors and surfactants. Surfactants reduce the surface tension between water and oil, allowing for more oil to be extracted from porous rock underground.

In a new study published in the journal Analytical Chemistry, the research team identified the surfactants found in fracking fluid samples from Colorado, Louisiana, Nevada, Pennsylvania and Texas. The results showed that the chemicals found in the fluid samples were also commonly found in everyday products, from toothpaste to laxatives to detergent to ice cream.

“This is the first published paper that identifies some of the organic fracking chemicals going down the well that companies use,” said Michael Thurman, lead author of the paper and a co-founder of the Laboratory for Environmental Mass Spectrometry in CU-Boulder’s College of Engineering and Applied Science. “We found chemicals in the samples we were running that most of us are putting down our drains at home.”

Imma Ferrer, chief scientist at the mass spectrometry laboratory and co-author of the paper said, “Our unique instrumentation with accurate mass and intimate knowledge of ion chemistry was used to identify these chemicals.”  The mass spectrometry laboratory is sponsored by Agilent Technologies, Inc., which provides state-of-the art instrumentation and support.
