PI:  Barb Keller, PhD

Funding provided by the USEPA Great Lakes Program Office allowed Keller and Rick Back (SUNY Oswego) to investigate metals contamination in surficial sediments in the St. Marys River and also in sediment cores collected in the Little Rapids and the Munuscong Bay areas of the St. Marys River.  Results of the metals research may be found on the BPAC website (www.lssu.edu/bpac).  Keller also worked with other LSSU faculty on the project Biotic Integrity of the St. Marys River Watershed Area.  This project was funded by the EPA GLNPO office.  Keller’s research for this project focused on the assessment of heavy metals in  water samples, sediment samples, and fish tissue collected within the St. Marys River watershed area.   Additionally, Keller recently worked with Dave Szlag (LSSU) to characterize water and sediment quality in Ashmun Creek and the Charlotte River, both of which empty into the St. Marys River. This work was funded by the Michigan Department of Environmental Quality Clean Michigan Initiative.
