Hydraulic Fracturing ("Fracking") FAQs - 15 Found
In general, hydraulic fracturing fluid is composed of water, proppant (typically sand), and chemicals. A public Web site known as FracFocus has been established by industry that lists specific materials used in many, but not all, hydraulically fractured wells. Individual companies select a few chemicals to be used from hundreds that are available and the fluids are tailored to the rocks they are being injected into as well as the conditions at the well site. Reporting to the FracFocus Web site is mandatory in some states and voluntary in the rest. The specific formulation of some chemicals may be trade secrets that may be exempt from reporting on the site.
