University of Iowa engineers spent a day collecting core samples from the Mississippi River.

The group of engineers was part of Keri Hornbuckle’s team. Hornbuckle is both a professor in UI’s Civil and Environmental Engineering department and a member of the Center for Global & Regional Environmental Research.

The team will study the core samples to determine PCB levels. This data will then be compared to previous data taken from the Iowa River.
