According to a 2010 congressional investigation, Halliburton along with other fracking companies had used 32 million gallons of diesel products, including toxic chemicals such as benzene, toluene, ethylbenzene and xylene. Low levels of exposure to such chemicals can trigger headaches and dizziness, while higher exposure can cause cancer.

In October, researchers found high levels of radioactivity, salts, and metals in water and sediment located downstream from a treatment facility which processes fracking wastewater from oil and gas production sites in Pennsylvania’s Marcellus shale formation.

A new report published this week in the latest edition of the journal Endocrinology shows a dozen chemicals used regularly in fracking are suspected of being endocrine disrupting chemicals, or EDCs — chemicals that can interfere with the human body’s endocrine functions and have been linked to heightened risks of cancer, low fertility rates and decreased sperm quality.

The widespread drilling technique is receiving scrutiny across the US, including places where energy development is commonplace.
