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]
AbstractThe purpose of this product is to make accessible the information about the 1,173 hydraulic fracturing-related chemicals that were listed in the external review draft of the Hydraulic Fracturing Drinking Water Assessment that was released recently. The product consists of a series of spreadsheets with physicochemical and toxicological information pulled from several sources of information, including: EPI Suite, LeadScope, QikiProp, Reaxys, IRIS, PPRTV, ATSDR, among other sources. The spreadsheets also contain background information about how the list of chemicals were compiled, what the different sources of chemical information are, and definitions and descriptions of the values presented.
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.
