Interesting, but well fracturing has been employed for years. More than 20 years ago I worked for an oilfield services company that commonly used fracturing to make wells more productive. I don't know how old the technology is, but why has it become an issue all of a sudden? 
Since it is a technology that has been widely used for years, is their actual, historical data to show that it is or has been a danger?
