EPA's Study of Hydraulic Fracturing for Oil and Gas and Its Potential Impact on Drinking Water Resources
Hydraulic Fracturing for Oil and Gas:
Impacts from the Hydraulic Fracturing Water Cycle on Drinking Water Resources in the United States
In 2016, EPA released the final report, “Hydraulic Fracturing for Oil and Gas: Impacts from the Hydraulic Fracturing Water Cycle on Drinking Water Resources”. Read the executive summary. Please note that this web site is no longer being updated.
This final report provides a review and synthesis of available scientific information concerning the relationship between hydraulic fracturing activities and drinking water resources in the United States.
The final assessment integrates results from EPA-led research efforts with approximately 1,200 cited sources of data and literature, and input from stakeholders through EPA's technical outreach.
The 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.
