Waterborne Pathogens in Great Lakes Tributaries

Great Lakes tributaries deliver pathogens from many different sources. This drawing represents the various sources of these pathogens along with hydrologic, land cover, and season patterns by which they enter the Great Lakes tributaries. It references the virus sampling that took place with the backdrop based largely on the Milwaukee, WI. This 2016 drawing renders viruses entering the environment through their microscopic form, a process that cannot be seen with the eye.
