The ongoing debate over fracking took another turn locally Tuesday when a group of northern Colorado moms opposed to the process took their case directly to an oil company that plans to drill near schools and homes.
The law grants physicians access to information about trade-secret chemicals used in natural gas drilling. Doctors say they need to know what's in those formulas in order to treat patients who may have been exposed to the chemicals.
But the new law also says that doctors can't tell anyone else — not even other doctors — what's in those formulas. It's being called the "doctor gag rule."
Quite a few of the 225 people who live in Dish, Texas, think the nation's natural gas boom is making them sick.
They blame the chemicals used in gas production for health problems ranging from nosebleeds to cancer.
And the mayor of Dish, Bill Sciscoe, has a message for people who live in places where gas drilling is about to start: "Run. Run as fast as you can. Grab up your family and your belongings, and get out."
A proposed study of people in northern Pennsylvania could help resolve a national debate about whether the natural gas boom is making people sick.
The study would look at detailed health histories on hundreds of thousands of people who live near the Marcellus Shale, a rock formation in which energy companies have already drilled about 5,000 natural gas wells.
If the study goes forward, it would be the first large-scale, scientifically rigorous assessment of the health effects of gas production.
