EPA study confirms that hydraulic fracturing can be performed safely and without impacting drinking water.

In March 2010, the EPA announced that it would conduct a research study to investigate the potential impacts of hydraulic fracturing on drinking water resources. In performing its study, the EPA followed water through all fracking-related phases—water acquisition, chemical mixing, well injection, collection of wastewater, and wastewater treatment and disposal. On June 3, 2015, the EPA released its draft assessment, finding no evidence that hydraulic fracturing has led to widespread, systemic impacts on drinking water. According to the assessment, although there is a potential to contaminate drinking water, the number of documented impacts to drinking water resources is relatively low when compared to the number of fractured wells. Thus, the draft assessment confirms that, if performed responsibly, hydraulic fracturing does not pose a threat to drinking water.
