What’s that smell?
Louisville, Ky., stinks.
Literally. Not figuratively. The place smells awful, and locals had no idea why.
That is until now. Officials with the Metro Air Pollution Control District say they’ve identified the source of the musty, mildew-like smell that has been hanging over the city for weeks, according to the Associated Press.
A chemical found in soil – called geosmin – is the culprit, according to local paper, The Courier-Journal. A spokesman for the district said the odor was “exacerbated by the wet, muddy conditions in the wake of the recent snowfall and rain.”
Last weekend, dozens of Louisville residents submitted odor complaints, and others took to social media with observations and theories for what was causing what the paper calls the “ubiquitous big stink.”
The Courier-Journal reports Nord said there isn’t a need to take any tests for the odor, and that it poses no threat to residents. “While we cannot say with absolute certainty that this is the cause of the odor, we are reasonably confident that this is the source," he said.
