Chemicals – amount: The industry says the percentage of chemicals mixed with water is small, but because the amount of water used is so great, the amount of chemicals is also great. A frack using 9 million gallons of water, of which only 1 per cent is made up of chemicals, still results in 90,000 gallons of chemicals injected into the Earth.
Chemicals – health: We have no information whatsoever on the health effects of nearly 80% of the over 1,000 chemicals used in fracking. Of those that have been studied, hundreds are associated with cancer and/or damage to the brain and nervous systems, immune and cardiovascular systems, kidneys, liver, eyes, skin, respiratory tract, gastrointestinal tract and reproductive system. There is no information on how they react when mixed with each other or with naturally-occurring toxic elements in the Earth. Living near a shale gas well is to be a guinea pig in the largest uncontrolled chemical experiment in the world. And the people running it don’t have to tell you the chemicals to which you are being exposed.
