Living within half a mile of a hydraulic fracturing site carries a serious risk for pregnant women, a new study has found. The drilling technique, also known as fracking, injects high-pressure water laced with chemicals into underground rock to release natural gas.
Women who lived within that distance to fracking operations in Pennsylvania were 25 percent more likely to give birth to low-weight infants than were mothers who lived more than two miles beyond the sites.
The five-year study of more than 1.1 million births in the state between 2004 and 2013, published Wednesday in the journal Science Advances, also found lower birth weights, although not as low, in infants whose mothers lived between half a mile and two miles from a fracking site. Beyond two miles, there was no indication of any health effect to newborns, a significant drop-off, the study said.
