Fracking, the increasingly popular strategy of breaking up underground shale formations using pressurized solutions piped far under the earth to extract oil and gas, may lead to the environmental release of endocrine-disrupting chemicals (EDCs) that have previously been associated with birth defects, infertility, and cancer, according to a study published yesterday (December 16) in Endocrinology. Water sampled from hydraulic fracking sites in Colorado revealed the presence of such chemicals at higher levels than control sites, as did samples collected from the Colorado River, where wastewater from fracking operations could end up following accidental spills.
