AURORA, Colo. (April 9, 2018) – People living near oil and gas facilities along Colorado’s Northern Front Range may be exposed to hazardous air pollutants, including carcinogens like benzene, that could pose health risks above levels deemed acceptable by the U.S. Environmental Protection Agency, according to researchers at the Colorado School of Public Health, Boulder County Public Health, CU Boulder, the National Aeronautics and Space Administration (NASA) and the University of California Irvine.

The study, led by the Colorado School of Public Health at the University of Colorado Anschutz Medical Campus, used ambient air samples to estimate and compare risks for four residential scenarios. They found the lifetime cancer risk of those living within 500 feet of a well eight was times higher than the EPA’s upper level risk threshold.

“We found that air pollutant concentrations increased with proximity to an oil and gas facility, as did health risks,” the study said. “Acute hazard indices for neurological, hematological and developmental health effects indicate that populations living within 152 meters (500 feet) of an oil and gas facility could experience these health effects from inhalation exposures to benzene and alkanes.”

The cancer risk estimate of 8.3 per 10,000 for populations
