2. Announcement The EPA released its peer-reviewed analysis of over two years of data from the FracFocus Chemical Disclosure Registry 1.0. FracFocus is a publicly accessible website, managed by the Ground Water Protection Council (GWPC) and Interstate Oil and Gas Compact Commission, where oil and gas production well operators can disclose information about ingredients used in hydraulic fracturing fluids at individual wells. In March 2015: U.S. Department of the Interior Releases Final Rule to Support Safe, Responsible Hydraulic Fracturing Activities on Public and Tribal Lands. See Press release and Final rule.Press releaseFinal rule 2

3. EPA's Study of Hydraulic Fracturing for Oil and Gas and Its Potential Impact on Drinking Water Resources At the request of Congress, EPA is conducting a study to better understand any potential impacts of hydraulic fracturing for oil and gas on drinking water resources. The scope of the research includes the full lifespan of water in hydraulic fracturing. EPA's study will look at potential impacts of hydraulic fracturing at each stage of the Hydraulic Fracturing Water Cycle. 3 http://www2.epa.gov/hfstudy

16. Conclusions and Recommendations At the request of Congress, EPA is Studying Hydraulic Fracturing for Oil and Gas and Its Potential Impact on Drinking Water Resources at Each Stage of the Hydraulic Fracturing Water Cycle. In March 2015: U.S. Department of the Interior Released the Final Rule to Support Safe, Responsible Hydraulic Fracturing Activities on Public and Tribal Lands. This Rule was based on EPA peer-reviewed analysis of over two years of data from the FracFocus Chemical Disclosure Registry 1.0. EPA is Planning to Stand Up a Big Data Analytics Service and this Data Science for EPA Fracturing Data is an Example of EPA Big Data Analytics. This Data Science Data Product and Publication Includes a Knowledge Base in MindTouch, Excel, and Spotfire and Analytics and Visualizations in Spotfire. Additional Data Science Products and Publications Can be Done on More FracFocus PDF Files and the Access Database and Other EPA Projects. 16
