"Chesapeake Energy paid undisclosed fees to the lead author, whose study was based on water samples provided by the company."
"Drinking-water wells in Pennsylvania close to natural gas sites do not face a greater risk of methane contamination than those farther away, according to a new study published in Environmental Science & Technology (ES&T). But the study is now being called into question because of its methodology and some undisclosed ties to energy giant Chesapeake Energy.
The findings contradict recent studies that identified a correlation between proximity to natural gas wells and higher methane levels in well water. The new study analyzed more than 11,000 water samples collected by Chesapeake and provided to researchers.
Methane is the main component of natural gas and is not toxic for humans. But if the gas escapes from water taps and accumulates in confined spaces such as basements it poses a risk of explosion."
