Some critics of horizontal hydraulic fracturing to extract natural gas say it contaminates groundwater with carcinogens, impacts human health and causes widespread air pollution. But some scientists say they are misleading the public just as much drilling companies who may twist the facts about fracking.
Many of the claims made by critics "have little or nothing to back them," reports Kevin Begos of The Associated Press. Reports that breast cancer rates rose in a heavy gas drilling area in Texas are false, he reports. Fears that natural radioactivity in drilling waste could contaminate drinking water aren't being confirmed either, he writes, and concerns about air pollution aren't typically paired with information about how burning natural gas is cleaner than burning coal. Duke University professor Avner Vengosh, who studies groundwater contamination, told Begos, "The debate is becoming very emotional, and basically not using science" on either side. (Read more)
