Critics of fracking often raise alarms about groundwater pollution, air pollution, and cancer risks, and there are still many uncertainties. But some of the claims have little — or nothing— to back them.
For example, reports that breast cancer rates rose in a region with heavy gas drilling are false, researchers told The Associated Press.
Fears that natural radioactivity in drilling waste could contaminate drinking water aren’t being confirmed by monitoring, either.
And concerns about air pollution from the industry often don’t acknowledge that natural gas is a far cleaner burning fuel than coal.
“The debate is becoming very emotional. And basically not using science” on either side, said Avner Vengosh, a Duke University professor studying groundwater contamination who has been praised and criticized by both sides.
