Objective:

The University of Missouri at Rolla is conducting a metals fate and transport study on the two adjacent river systems of southeastern Missouri. These systems include the watersheds of the Big River and the West Fork of the Black River. Each river transects a world-class sized, lead-zinc district that is hosted in carbonate bedrock. The objective of this research project is to develop the necessary data for calibration and validation of comprehensive fate and transport models for heavy metals to be developed within the Center for the Study of Metals in the Environment. The working hypothesis of this study is that the transport and bioavailability of heavy metals in streams impacted by mining activity are a function of particle size distribution, mineralogy, density, acid leachability, specific surface area, and other key parameters. The heavy metals to be investigated include lead (Pb), zinc (Zn), copper (Cu), cadmium (Cd), and nickel (Ni).
