Cancer-Causing Benzene Found In Barnett Shale-WE HAVE BEEN EXPOSED!!

After reading this article I was a little disturbed that no one said anything about the men and women that are working these drilling rigs and their risks. They have been exposed to this gas for years now...WHAT HAPPENS TO THEM?? Who is responsible for dropping the ball on air quality control on these rigs? Is the drilling companies responsible...the government..WHO? Better yet....Did all of them know the risks and know about the cancerous gas and still let it happen?? Someone needs to take the blame for this one. My family and many others are the ones who are going to pay for this.
