EPA's Study of Hydraulic Fracturing and Its Potential Impact on Drinking Water Resources

EPA Project Database Developed from FracFocus 1 Disclosures

Together, the Data Management and Quality Assessment Report and project database can be used to reproduce the EPA’s analysis, better understand the EPA’s methods, or perform additional analyses.

Data in the disclosures were extracted from individual PDF files and compiled into a Microsoft Access 2013 database, which was used for analyses. An explanation of the database queries and the statistical codes used to develop the tables and figures from the FracFocus 1.0 Data Analysis is included.
