There's something in the air: City officials investigating mysterious odor in Louisville, Kentucky

Something stinks in Louisville

Something in the air doesn't smell right and city officials are trying to find out what it is.

Complaints started coming in early last week for a mysterious odor in Louisville, according to the Air Pollution Control District.

"I smell a musty smell, like something that's gotten wet. Like a, kind of like a wet dog," Joel Houghton told WDRB News.

"I noticed a smell and I pointed it out to her," Jason Culver said. "I have no clue what it is."

The Air Pollution Control District has been sending people out to investigate the smell of mold and mildew in the air.

"We're used to getting complaints," spokesman Thomas Nord said. "It's unusual that we get the same complaint in such a widespread area."

Nord says calls originated around I-65 near the Watterson and moved to other parts of the area.

Comments on WDRB's Facebook support that point.

Kim wrote, "I-65 at Fern Valley. So bad that you have to close the vent on the car and it's still bad."

Monte said, "I smelled mold in Fairdale Friday afternoon and now smell it way up here in Prospect this morning."

Nord says there doesn't seem to be an obvious source yet but the agency does not believe the smell is toxic.

Investigators are checking with companies but say something organic or the weather could be to blame.

"We're hopeful that we can figure this out," Nord said. "Just if anything so people have some conclusion, so we're hopeful we can get to the bottom of this."
