Description:
The Lake Michigan Mass Balance Project (LMMBP) was initiated to support the development of a Lake Wide Management Plan (LaMP) for Lake Michigan. As one of the models in the LMMBP modeling framework, the Level 2 Lake Michigan containment transport and fate (LM2) model has been developed for the project to address the relationship between sources of toxic chemicals and their concentrations in air, water, sediment, and biota. The LM2 containment transport and fate model is a coupled, organic carbon sorbent and toxic chemical model. The target containments for this modeling task are 37 PCB congeners. The model was calibrated for each organic carbon sorbent and PCB congener from field-collected data during the project period. The model was then applied for long-term forecasts of contaminant concentrations in water and sediment of Lake Michigan under different forcing functions and loading scenarios. This paper will present and discuss the results of model calibration, long-term scenario runs, the most significant pollutant sources, and key environmental processes in Lake Michigan.
