EPA Subpoenas Halliburton, Seeking Fracking Secrets | CommonDreams.org.

Chemicals used in hydrofracking are possibly harmful to our drinking water.  The EPA served Halliburton a subpoena to unveil the chemicals used in this process.

On September 9, EPA asked nine national and regional hydraulic fracturing service providers – BJ Services, Complete Production Services, Halliburton, Key Energy Services, Patterson-UTI, RPC, Inc., Schlumberger, Superior Well Services, and Weatherford – for information.

Except for Halliburton, the companies have either fully complied with the September 9 request or made unconditional commitments to provide all the information on an expeditious schedule, the EPA said.

A 2005 vote in Congress exempted the practice of fracking from regulation by the Clean Water Act after a 2004 federal government study determined that the practice poses little threat to human health.

But fracking has polluted drinking water sources in Wyoming, Colorado, Texas, Arkansas, Pennsylvania and New York, according to state and federal regulators in a September survey of more than 100 cases compiled by the nonprofit Hudson Riverkeeper.

While the exact components of each fracking fluid mix are closely held industry secrets, previous studies and a congressional investigation have shown they may contain barium, strontium, benzene, toluene, ethanol, and nonylphenols, diesel fuel, acetone, boric acid, ethelyene glycol, isopropanol, hydrochloric acid and/or formic acid.
