Hormone-disrupting chemicals linked to cancer, infertility and a slew of other health problems have been found in water samples collected at and near hydraulic fracturing, or "fracking," sites in Colorado, according to a new study published in the journal Endocrinology this week.
Researchers say they found elevated levels of these chemicals -- known as endocrine-disrupting chemicals (EDCs) -- in surface water and groundwater samples collected in the state's Garfield County, a fracking hotspot with more than 10,000 natural gas wells.
Water samples taken from the Colorado River, a drainage basin for the region, were also found to have significantly higher-than-normal levels of EDCs, the researchers said.
EDCs, which have the ability to interfere with normal hormone action, have been linked to a number of health issues. Last year, the World Health Organization issued a report highlighting the health risks associated with the chemicals, including cancer, infertility and impaired neural and immune function. Previous studies have also suggested that EDCs may have adverse effects on the reproductive system in both women and men.
