• Environmental Protection Agency (US EPA) provides information about hydraulic fracturing and its environmental impacts on the USEPA web page: Unconventional Oil and Gas Development. In addition, the EPA is currently studying the effects of hydraulic fracturing on drinking water resources. While the draft report is expected in 2014, a progress report outlining initial findings was released in December 2012. The Study of the Potential Impacts of Hydraulic Fracturing on Drinking Water Resources - Progress Report conducted by the EPA is complete.
• United States Geological Survey (USGS) provides information about the process of hydraulic fracturing and impacts of the use of hydraulic fracturing through the Science Explorer: Exploring Hydraulic Fracturing web page.
• FracFocus is a national hydraulic fracturing registry that is primarily concerned with groundwater protection. The FracFocus webpage also provides information on hydraulic fracking regulations in all 50 states.
