And because of data protection No-One knows what chemicals are used.
Another example of how corporations embrace any and all measures that will increase their private profits for a few by socializing costs onto the backs of the largely uninformed, unorganized many.

"In order to hydraulically fracture shale and extract the hydrocarbons, large quantities of water and chemicals must be injected underground.
"Thus
fracking can pose a threat to local water resources, especially in areas where water is already scarce like the Barnett shale in Texas.
"In the Marcellus Shale region, the most expansive shale play in the United States, 2 to 10 million gallons of water are needed every time a well is fractured.
"Because wells can be fractured multiple times, the total amount of water used for fracking is unknown and can vary by location and technology.
"In western states like Texas and Colorado, over 3.6 million gallons are needed per fracture.
"In 2010, the U.S. EPA estimated that 70 to 140 billion gallons of water were used to fracture just 35,000 wells in the United States, more than was used by the city of
Denver, Colorado in the same time period.
"As of 2012, the fracking industry has drilled around
1.2 million wells, and is slated to add at least 35,000 new wells every year. (Jeff Goodell, '
