since when does sediment float?

Perhaps they have chosen the wrong word: "sediment - matter that settles to the bottom of a liquid"

It would have been good it they have mentioned was this stuff was made of. When I was a kid swimming in Lake Erie, we called undefined floating matter "scuzz."

It might start with an S, but it isn't scuzz....

The Late Comedian,George Carlin, had a bit where he claimed that he and his companions never got sick...cuz they swam in the East River...in raw sewage.

Yup, forty plus years ago swimming in Saginaw Bay one wanted to avoid both the scuzz and the sediment.
