A method for generating a visualization for tracking an environmental contaminant includes automatically generating a contaminant visualization map for a particular contaminant. The contaminant visualization map includes a plurality of markers each corresponding to a location associated with a medical case associated with exposure to the particular contaminant, and one or more markers each corresponding to a location of an identified contamination source for the particular contaminant. The method further includes receiving an indication to zoom out the contaminant visualization map, generating one or more heat maps corresponding to the medical cases associated with exposure to the particular contaminant, and updating the contaminant visualization map to be zoomed out, not display the plurality of markers each corresponding to a location associated with a medical case, and display the generated one or more heat maps.
