A foul smell around Wacker Drive and the Chicago River that brought fire and police crews to check for a source Tuesday morning may have been caused by a leaky garbage truck.
A HazMat response was called by the Chicago Fire Department in the 100 block of North Wacker Drive about 11 a.m. after a foul odor was reported coming from the area, according to Fire Media Affairs.
Fire and police crews worked for a couple hours to try to identify the source of the odor, but by about 1:20 p.m., Fire Media Affairs reported the source of the smell could not be found and the HazMat response was secured.
It was believed the odor could have been caused by a garbage truck that was leaking while traveling on Lower Wacker, Fire Media said.
No injuries were reported.
