Indeed Rocket, perhaps it's the first sign of light at the end of the tunnel. Here's a supplementary link on the same subject. I've highlighted the last paragraph, is there any reason left to oppose fracking now?

SteriFrac is the first eco-friendly biocide that will not harm ground water, area land or jeopardize the health of workers during the fracking process. Traditionally the fracking process pumps a mix of water, sand, and toxic chemicals (a biocide) into a well at high pressure in order to create fractures in the shale allowing the gas and oil to escape. There is a concern that the chemicals presently used in the fracking process may pollute the area ground water or soil where as SteriFrac as an effective non-toxic, non-combustible and non-corrosive biocide cannot harm the environment.

“SteriFrac is the finest biocide I’ve seen in the 32 years that I have worked in the oil field,” notes Max Duncan, President of Integrity Industries, a division of Weatherford International, NYSE-WFT. “Our customers have replaced their traditional biocides with SteriFrac due to its lasting impact, odor-killing capabilities and eco-friendly nature.”

The product is both EPA and FDA approved for use in fracking as well as for a drilling and completion fluid. SteriFrac is unique in that it is a pH neutral biocide (hypochlorous acid) that kills bacteria –quickly – without any toxic odors, fumes or fluids. Industry users can now optimize the gas and oil extraction process in U.S. wells without alarming landowners, area citizens, or community conscious environmentalists.
