EPA Hydrofracking Study
At the request of congress, EPA is conducting a study of hydrofracking to learn more about its impacts on drinking water resources. The study's homepage is here.
In December 2012 EPA released a progress report
On Dec 20, 2013 EPA published links to scientific papers and technical
roundtable meeting materials that will contribute tho their draft report
of potential impacts of fracking on drinking water sources.
Scientific papers are available here, with future papers posted as they become available.
Technical roundtable materials here, including:
Study Update: Potential impacts of hydraulic fracturing on drinking water resources
Overview of EPA's hydraulic fracturing drinking water assessment report
In 2013 the EPA hosted four technical workshops. You'll find information about each workshop here as well as case studies and other stuff.
On January 28, 2014 EPA hosted a one-hour public webinar to share what was discussed at the Technical Roundtable. You can see the presentation here.
On June 5, 2015 - EPA released a draft assessment of the potential impacts of oil and
gas hydraulic fracturing activities on the quality and quantity of
drinking water resources in the United States for public comment and
peer review. The draft assessment is based upon extensive review of
literature, results from EPA research projects, and technical input from
state; industry; non-governmental organizations; the public; and other
stakeholders. Read it here.
