Compilation of Physicochemical and Toxicological Information About Hydraulic Fracturing-Related Chemicals (Draft Database)
NoticeThis product is being released in support of the hydraulic fracturing study (HF Study) assessment and is available to provide the information that was used to determine the potential impacts of hydraulic fracturing for oil and gas on drinking water resources in the United States. This is companion data to the draft report that was released for public comment and shared with the EPA Science Advisory Board for expert peer review. [Press Release Jun 4, 2015]
Hydraulic fracturing in combination with advanced directional drilling techniques has made it possible to economically extract oil and gas from unconventional resources, such as shale, tight formations, and coalbeds. The growth in domestic oil and gas exploration and production made possible by the expanded use of hydraulic fracturing, has raised concerns about its potential for impacts to human health and the environment. Specific concerns have been raised by the public about the effects of hydraulic fracturing on the quality and quantity of drinking water resources.
The U.S. Congress urged the U.S. Environmental Protection Agency (EPA) to study the relationship between hydraulic fracturing and drinking water resources. In 2011, the EPA published its Plan to Study the Potential Impacts of Hydraulic Fracturing on Drinking Water Resources. The research described in the Study Plan began the same year and has resulted in 12 EPA reports and several journal publications. The Assessment of the Potential impacts of Hydraulic Fracturing for Oil and Gas on Drinking Water Resources, which this draft compilation of chemical information supports, uses the results from EPA-led research projects and the results of hundreds of other publications to provide a synthesis of the science related to hydraulic fracturing and drinking water resources.
