The green color that East Moline maintenance workers spotted in the Mississipi River is algae, according to environmental professionals from John Deere.

The color appeared because of a high amount of green algae in the water. It was identified along the shoreline between Hampton and East Moline.

In a statement a spokesperson from John Deere said, "Deere has its own waste water treatment process within the Harvester Works and does not release paint waste into the Mississippi River."

East Moline maintenance workers spotted a mysterious green substance in the Mississippi River Wednesday.

It was spotted at Empire Park and Beacon Harbor on Route 84 before 8 a.m. The harbor is located on the border between Hampton and East Moline.

Crews are not saying what the substance is specifically, but crews were calling it a "John Deere" color Wednesday. Crews found the substance in a 30 yard area of the bank.

Crews believe it's either algae or paint that got washed up on the river, but they don't know that for sure. No boats or people look to be affected by the substance.

Workers from the East Moline Water Department are currently testing the substance. They could release more information later on Wednesday.
