Researchers used infrared cameras to scan for methane gas leaks at over 8,000 U.S. sites.
The leak has released more than 90,000 metric tons of methane already.
More than 20 private lawsuits have been filed on behalf of some of those residents.
"My fear is that when you actually take a hard look at these facilities, there’s going to be a lot to be worried about," one geologist says.
WHAT'S HAPPENING
The leak, first reported in October, has spewed up to 1,200 tons of methane daily.
