Science has struggled to keep pace with the rapid expansion of hydraulic fracturing–commonly called fracking–over the last decade. Concerns over environmental impacts and implications for human health have caused several state legislatures and local municipalities to enact stricter regulations on drilling processes and establish moratoriums until more science is available. Currently, oil and gas fracking wells are active in more than 20 states.
Fracking injects millions of gallons of fluid — a mixture of water, sand and undisclosed chemicals–into a deep well to fracture the rock and release gas or oil. In some cases, the fluid returns to the surface with new, dangerous chemicals such as arsenic, a known carcinogen.
1) Nearly 700 unique chemicals are used in fracking. The individual impact of these chemicals on human health remains largely unknown, thereby limiting how much health care providers and emergency responders can assist residents living close to drilling sites. (EPA)
2) Faulty cement well casings can cause toxic chemicals to leach into the local groundwater. A recent study found that nine percent of wells drilled since 2009 already have structural integrity issues. (PNAS)
3) Injecting oil and gas wastewater back underground for disposal has been linked to an increase in earthquake frequency across the country, including 585 quakes greater than magnitude 3 in Oklahoma in 2014, compared with 109 quakes in 2013. (USGS)
4) Natural gas and petroleum systems account for 33% of U.S. methane emissions due to leaks. Methane is a potent greenhouse gas that impacts climate change at least twenty times more than carbon dioxide. (EPA)

Science and Reports
News research on fracking is constantly emerging, and the majority of studies have occurred since 2012. Peer-reviewed science continues to identify potential risks and dangers to public health and the environment.
A compilation of studies and reports related to fracking is available below, along with a short summary of each resource. The science is all peer-reviewed and the reports are issued by government agencies or other organizations working on fracking issues. These resources will be regularly updated.
- Wastewater Disposal from Unconventional Oil and Gas Development Degrades Stream Quality at a West Virginia Injection Facility — Environmental Science & Technology, 2016
This USGS research paper analyzed the impact of wastewater injection on a nearby streams. The study determined that the stream was being directly impacted by chemicals from the wastewater injection, and that microbial communities essential for ecosystem foodwebs are changing as a result. More studies are underway to further investigate the extent of the impact.
- Spills of Hydraulic Fracturing Chemicals on Agricultural Topsoil: Biodegradation, Sorption, and Co-contaminant Interactions — Environmental Science & Technology, 2016
Researchers investigated how long fracking chemicals remain in the soil after usage, and the study underscored the need for additional research into how fracking spills interact with agricultural land. The study simulated spills and analyzed the chemical reactions that occur to determine how quickly certain chemicals break down. If chemicals are slow to break down, they have a higher chance of reaching sensitive surface or groundwater. A news release on the study is available here.
- Elucidating Hydraulic Fracturing Impacts on Groundwater Quality Using A Regional Geospatial Statistical Modeling Approach — ScienceDirect, 2016
