This is the part I like:
The study, published in New Solutions: A Journal of Environmental and Occupational Health Policy, stated that, while likely, making a direct link between death and illness is not possible at this time because of inadequate data due to the proprietary secrecy of gas drilling companies regarding the chemicals used in hydrofracking, and non-disclosure agreements that seal testimony and evidence when lawsuits are settled.Several companies have made public the chemicals they use in the fracking water. From what I recall, there is nothing magic about any of the chemicals. Most if not all of these are what are used in modern cooling water systems to control water quality. The water in cooling towers is "blown down" to rivers and streams...because there is no danger to living animals since the residual amounts of chemicals are so small. In fact, some may be beneficial (I'd have to look it up, but there is a good possibiity I'm right). For instance, chemicals are added to control algae growth. Algae blooms are a real problem in rivers and streams and can kill fish.
