A garbage truck that leaked is being blamed for a strong odor along Lower Wacker Drive, officials said.
The hazardous materials response was secured about 1:30 p.m., according to the Chicago Fire Department. Nothing was found but officials believe the odor may have been caused by a garbage truck that leaked while traveling on Lower Wacker, the fire department said.
The hazmat was called around 11 a.m. for the 100 block of Lower North Wacker Drive, according to Fire Department spokesman Cmdr. Sean Flynn. Flynn said they were working with the police to investigate.
At 7 a.m., someone called 911 from that address to report the odor. By 8 a.m., several patrol officers on foot and police dogs were sent there to investigate, police said.
No buildings were evacuated and traffic, including foot traffic, has not been rerouted, according to police News Affairs Officer Jose Estrada.
“There’s an overpowering odor and they’re trying to figure out what’s causing it,’’ Estrada said earlier.The odor was noticeable through much of Lower Wacker Drive today, including all the way to the 400 block of Lower North Michigan Avenue.
The city’s Department of Sewers was also notified, police said.
