While out and about last Tuesday, August 20th, in Coon Rapids, Minnesota, people started to notice something odd in the Mississippi River below. It was a strange-looking sheen, or shiny look, on the surface of the water.

What Was the Weird Sheen in the Mississippi River?

The Minnesota Pollution Control Agency (MPCA) gathered a sample and brought it in for testing. They determined that it was a type of lubricant. A lubricant that's used at the Coon Rapids Dam.

Turns out, a crew had been working on the dam that morning when something malfunctioned and about 30 gallons of lubricant spilled into the Mississippi... Don't worry, officials told KARE 11 and many other sources that "the lubricant is not harmful if it gets into contact with food, and drinking water is safe."

However, as of the end of last week, there were measures being taken to prevent the spill from getting into the drinking water systems of Minneapolis and St. Paul.
