A four year U.S. Environmental Protection Agency study is put out in June 2015. It confirms that fracking can be carried out safely without contamination of drinking water. The EPA says there are a small number of contaminated drinking water wells and describes the vulnerabilities. Thomas Burke, deputy assistant administrator of the EPA's office of research and development says: "The hydraulic fracking activities in the U.S. are carried out in a way that have not led to widespread, systematic impact on drinking water resources. In fact, the number of the documented impacts to drinking water is relatively low compared to the number of fractured wells." Rob Jackson, an earth sciences professor at Stanford University, who has studied the environmental impact of fracking, says he agrees with this conclusion of no widespread impact, but says the report needed to be more comprehensive. Burke said in a conference call that the main issue was "understanding the vulnerabilities so we can address the vulnerabilities and practice hydraulic fracking in the safest possible way."
