Enormous Methane Leak From Ohio Gas Well Was One of Worst In American History, Satellites Reveal
A new study has determined that a gas well blowout in Belmont County, Ohio last year was one of the most significant ever to occur in the country. Newsweek reports: In a study published in the Proceedings of the National Academy of Sciences, a team of scientists estimated that the gas well -- owned by ExxonMobil -- leaked around 120 metric tons of methane per hour over a period of 20 days before the company managed to fix the problem. This amounted to a total of more than 50,000 tons of methane. The authors -- led by Sudhanshu Pandey from SRON Netherlands Institute for Space Research -- said that the hourly emission rate from the leak was about twice that of the widely reported event at an oil and gas storage facility in Alison Canyon, California, which took place in 2015 -- the largest known methane leak in the country. While the emission rate of the Ohio event was higher, the California event lasted longer and produced more emissions overall, The New York Times reported. Nevertheless, the leak at the Belmont County well still released vast amounts of methane into the atmosphere, according to the researchers. In fact, it emitted more of the gas in 20 days than the oil and gas industries of some European nations do in a year. The scientists detected the leak using an instrument known as TROPOMI on the recently launched European Space Agency satellite Copernicus Sentinel-5P, which is designed to continuously monitor methane and other pollutants. [...] The Ohio incident did not garner much attention at the time, although 100 residents within a 100-mile radius had to be evacuated from their homes while workers attempted to fix the leak. Some of these residents had complained of health issues such as throat irritation, dizziness and breathing problems.Read more of this story at Slashdot.
