Let's play multiple choice. In the typical fluid mix used to produce natural gas from shale during hydraulic fracturing, the percentage of water/sand/chemicals is:
A) 70 percent water, 20 percent sand, 10 percent chemicals.
B) 80 percent water, 15 percent sand, 5 percent chemicals.
C) 90 percent water, 9.5 percent sand, 0.5 percent chemicals.
The answer is ... "C." Surprised? Lots of folks are, given the number of inaccuracies about hydraulic fracturing that are circulating. Fracturing fluid is 99.5 percent water and sand - the sand being used to prop open tiny fissures in the shale to release the natural gas. Only one-half of 1 percent of the mix is chemicals.
Ready for another surprise? Chemicals in the typical fracking mix (the 0.5 percent) are additives found in common household items such as cosmetics, table salt - even ice cream.
