The Environmental Protection Agency is investigating an oil spill in the Little Cuyahoga River in Akron.
Around 4:40 p.m., according to the City of Akron, the Akron Fire Department received a call to the intersection of East Market and Massilon Road to investigate a report of unknown oil in the river.
A hazmat team arrived at the scene to contain the spill, and the EPA and other fire department officials were also called to assess the incident.
On Monday, the Ohio EPA said the spill was petroleum traced to a vacant industrial building and was less than 100 gallons in volume.
Some of the spill made it into a storm drain that flowed into the Little Cuyahoga River, but "containment measures" prevented it from flowing further downstream.
No drinking water, wildlife or aquatic life was threatened by the spill, the Ohio EPA said.
