Dr. Hartmann earned his B.S. in Earth Science with a minor in Chemistry from Southern Connecticut State University. He then went on to the University of Rhode Island for a Ph.D. in Oceanography, specializing in organic geochemistry. His dissertation was on the sources, transport and fate of organic contaminants in estuarine sediments. For his postdoctoral research he studied possible chemical reasons for the decline of trout populations in Swiss rivers at the Swiss federal Institute for Environmental Science and Technology.
