MISHAWAKA, Ind. -- South Bend Fire HAZMAT crews responded to the Mishawaka household hazardous waste facility on E 5th Street Thursday morning.

They were called out just before 10 a.m. for an investigation of a barrel brought in from a Mishawaka school.

South Bend Fire Battalion Chief Bob Means said someone noticed bubbling in the liquid inside the metal barrel.

The barrel was placed inside a larger barrel and a sample was taken from the liquid inside.

The barrel had been under the stadium for several years.

Means said they believe the liquid is diesel fuel, but they won't know for certain until a chemical analysis is complete.

Means says the barrel was taken to a private environmental company.
