The first research into the effects of oil and gas development on babies born near wells has found potential health risks. Government officials, industry advocates and the researchers themselves say more studies are needed before drawing conclusions.
While the findings are still preliminary, any documented hazards threaten to cast a shadow over hydraulic fracturing, or fracking -- the process of blasting chemicals, sand and water deep underground to extract fuel from rock that’s helped push the U.S. closer to energy self-sufficiency than at any time since 1985.
“It’s not really well understood how the environment interacts with genetics to produce these birth defects,” said Lisa McKenzie of the Colorado School of Public Health, who conducted research published in January in the journal Environmental Health Perspectives. “We really need to do more study to see what the association is, if any, with natural gas development.”
McKenzie and her colleagues discovered more congenital heart defects in babies born to mothers living near gas wells in Colorado. Two studies, which have not been peer reviewed, showed infants born near fracking sites in Pennsylvania were more likely to have low birth weight, a sign of developmental problems. In Utah, local authorities are investigating a spate of stillbirths after tests found dangerous levels of air pollution from the oil and gas industry.
