    Terrace View Park Pond in Lombard, IL by Tony Ream

    We finally have had a little bit of snow this last month and some days have been really cold. So they have had to salt a few times. The pond is pretty much frozen over except at the outlet where I take samples.

    Bridge over river on Gartner Road near Edgewater Drive by Antara Prasad

    Collected the sample at night again. It was the warmest day of the week but there was still ice on the river. We found a patch where there was no ice and lowered our bucket into the water. The ppm results were the same from our reading in December.
