A Duke University study released Monday found high levels of methane pollution in some Pennsylvania water wells within a half-mile from drilling, while another from the U.S. Geological Survey found some serious methane pollution occurring naturally, far from drilling.
Duke researcher Rob Jackson says their paper shows that methane contamination is “not an epidemic” but does exist. Methane is an odorless gas that is not known to be toxic, but high concentrations can be explosive… (more)
