DETROIT – A substance discovered Friday in a Detroit building will be tested because officials believe it is the same chemical found on I-696 in Madison Heights last month.

Crews worked all weekend boarding up the building and locking the doors.

“Some of the liquid in some of the pits are green, which is similar to what we found at the Madison Heights property," said Jill Greenberg with the Dept. of Environment, Great Lakes, and Energy. "That’s why we’re gonna have contractors on site Monday to do additional tests to figure out what is the substance and what extent of contamination exists at the site.”

A fence around the building is expected to be built Monday to keep people out.
