Chemicals detected in flowback and produced water - collectively referred to as - hydraulic fracturing wastewater

From EPA in USA 2005-2011 - Study of the Potential Impacts of Hydraulic Fracturing on Drinking Water Resources PROGRESS REPORT - December 2012 - US Environmental Protection Agency Office of Research and Development Washington, DC

This data includes chemicals reported to be used in hydraulic fracturing fluids and chemicals detected in flowback and produced water. Sources of information include federal and state government documents, industry­provided data, and other reliable sources based on the availability of clear scientific methodology and verifiable original sources; the full list of information sources is available in Section A.1. (Reference - "Study of the Potential Impacts of Hydraulic Fracturing on Drinking Water Resources" - EPA in USA) The EPA at this time has not made any judgment about the extent of exposure to these chemicals when used in hydraulic fracturing fluids or found in hydraulic fracturing wastewater, or their potential impacts on drinking water resources.

Additionally substances exist not shown here that may have serious health consequences upon exposure. Stay informed by signing up on any of our toxin profile pages. See our References and Toxin Profiles for additional details.
