Expectant mothers who live near active natural gas wells operated by the fracking industry in Pennsylvania are at an increased risk of giving birth prematurely and for having high-risk pregnancies, new Johns Hopkins Bloomberg School of Public Health research suggests.
The findings, published online last week in the journal Epidemiology, shed light on some of the possible adverse health outcomes associated with the fracking industry, which has been booming in the decade since the first wells were drilled. Health officials have been concerned about the effect of this type of drilling on air and water quality, as well as the stress of living near a well where just developing the site of the well can require 1,000 truck trips on once-quiet roads.
“The growth in the fracking industry has gotten way out ahead of our ability to assess what the environmental and, just as importantly, public health impacts are,” says study leader Dr. Brian S. Schwartz, a professor in the Department of Environmental Health Sciences at Johns Hopkins. “More than 8,000 unconventional gas wells have been drilled in Pennsylvania alone and we’re allowing this while knowing almost nothing about what it can do to health. Our research adds evidence to the very few studies that have been done in showing adverse health outcomes associated with the fracking industry.”
In Pennsylvania in 2006, there were fewer than 100 unconventional gas wells; now there are more than 8,000.
