"The public has a right to know": Fracking companies don't have to disclose chemicals linked to health concerns

"A huge breakthrough in modern fracking came in 1997, courtesy of a stubborn, tenacious Texan named George Mitchell. After 17 years of trial and error, he and his team stirred up a secret recipe of water, chemicals and sand, shot it down a well, and lots of natural gas came back up. Mitchell has since passed away but his colleague Kent Bowker remembers the moment they cracked the code. “Mr. Mitchell got this big smile on his face. And he leans forward and he looks at all of us: 'This is huge, this is the biggest thing that's ever happened to this company. It's also the biggest secret. No one can talk about this!'” Bowker said."
