The wind “was blowing North East at approximately 10 mph and carried this odor across the town,” said the department. “Methanethiol, also known as methyl mercaptan, is an organosulfur compound. It is a colorless gas with a distinctive putrid smell. This chemical is used in the natural gas industry as an odorant, as it mixes well with methane.”
“The characteristic ‘rotten eggs’ smell of the mix is widely known by natural gas customers as an indicator of a possible gas leak, even a very minor one,” wrote the Fire Department on social media.
