Living Near Fracking Sites Raises Risk of Premature Death For Elderly, Study Finds

An anonymous reader quotes a report from The Guardian: Elderly people living near or downwind from unconventional oil and gas wells such as fracking sites are more likely to die prematurely, according to a major new US study. Extracting oil and gas through newer or unconventional methods like fracking has expanded rapidly across America over the past two decades with at least 17.6 million people now living within one kilometer of an active well. Compared with traditional drilling, unconventional oil and gas development (UOGD) is linked to higher levels of exposure to toxic air pollution and poor water quality, as well as noise and light pollution which can be harmful to human health. The impact of fossil fuel extraction -- including by unconventional methods -- has disproportionately affected low income communities and people of color.

Researchers from the Harvard TH Chan School of Public Health studied the health records of 15 million people on Medicare, the health insurance program that includes at least 95% of Americans aged 65 and older, living in all significant drilling regions from 2001 to 2015. They also gathered data on about 2.5 million oil and gas wells covering leading exploration states, from Montana to Texas and Pennsylvania. The closer people live to an oil and gas operation, the higher the risk of dying prematurely, even after accounting for socioeconomic, environmental and demographic factors such as gender and race, according to the study published in Nature Energy.

Residents most adversely affected are those living nearby and downwind, suggesting toxic airborne contaminants emitted from UOGD sites probably contributed to higher mortality rates. Exposure to toxins associated with unconventional drilling such as volatile organic compounds (VOCs), nitrogen oxides and radioactive materials are linked to a wide range of life-threatening medical conditions. Overall, elderly residents living near these wells have about 2.5% higher mortality rates than those living far away compared with 3.5% for those who are also downwind. This would mean thousands of premature deaths linked to the oil and gas boom, though the peer-reviewed study does not include estimates of lives lost.
