According to the linked Swiss Re expert publication, between 1 million and 8 million gallons of fluid and 80 to 300 tons of chemicals collectively known as “fracking fluid,” are used to fracture a single well. Nearly all of the “fracking fluid” consists of sand and water, but it also carries chemical combinations used as part of the fracturing process which can consist of up to 200 different types of chemicals. In addition to the variable chemical composition of the fracking fluids when injected into the well, the flow back slurry may also have variable chemical concentrations and composition (60 to 90% of fracking fluid remains in the well). Also, the flow back water will contain natural constituents such as radon, metals, minerals and constituents of natural gas collected during its journey down the well and back up again. As a result, the chemistry of the water coming out of the ground may be quite different from what goes into the well. Good insights here > http://media.swissre.com/documents/pub_fracking_032712.pdf
