The EPA took samples from 37 sites in Northern Pennsylvania in 2011 to examine potential water contamination from fracking chemicals. These 37 sites included 34 wells, two springs, and one stream.
The samples were part of a study examining several stages of the fracking process, including injection of treated water into a site, removal and disposal of that water, and any contamination with other water supplies in the area.
The results will be released on the EPA website over the next few weeks. The EPA performed a similar assessment of fracking in Dimock Township two years ago. No cause for further action was found by the EPA in those samples.
Fracking uses many chemicals which are unknown the public. Many are a trade secret, unreleased even to the government while attempting to regulate the industry. The industry claims fracking is safe when performed properly.
A full report on the findings of environmental impacts to Northern Pennsylvania from fracking is expected sometime in 2014.
