Preliminary testing on the substance discovered in the Huron River near the University of Michigan's Nichols Arboretum earlier this week showed it was petroleum-based, officials said.

It's believed the spill could have come from someone dumping fuel or some other chemical down a storm drain, said Diane Brown, spokeswoman for U-M's Department of Public Safety.
No further testing will be done on the substance because it appears to be an isolated discharge and is no longer flowing into the river, Brown said.
A passerby noticed a sheen on the surface of the water Monday evening and reported it to the Ann Arbor Fire Department. It appeared to be coming from a storm drain near the river.
Booms were put out on the water to absorb as much of the chemical as possible, but the current and heavy storms Monday evening dispersed it, officials said.
