Once used for buttons and freshwater pearls, mussel shells from the Wabash River allow researchers to date current populations of the species and learn more about the river’s water quality. Indiana State University’s Dr. Jim Speer, Professor of Geography and Geology, and Hilary Howard, a Master’s degree student in the Department of Earth and Environmental Systems, will discuss the methods used to conduct their research and how they can use this information to measure the impact of the Clean Water Act on the local river system.
