Another damning report on fracking
Many of the ingredients were “extremely toxic,” including benzene, a known human carcinogen, and lead. Companies injected large amounts of other hazardous chemicals including 11.4 million gallons of fluids containing at least one of the toxic or carcinogenic B.T.E.X. chemicals — benzene, toluene, xylene and ethylbenzene. The companies used the highest volume of fluids containing one or more carcinogens in Colorado, Oklahoma and Texas.
The report comes two and a half months after an initial report that found that 32.2 millions of gallons of fluids containing diesel, considered an especially hazardous pollutant because it contains benzene, were injected into the ground during hydrofracking by a dozen companies from 2005 to 2009, in possible violation of the drinking water act.
