Caption:
This historic 1922 drawing, which had been digitally enhanced, depicted the sources of water-borne pollution responsible for a typhoid fever epidemic at the Lake Julia Sanatorium, in Puposky, Minnesota. The pumping station on the lower right did not filter the water effectively enough to neutralize the contamination resulting from the institution’s sewer line emptying into the potable water source on the left. This was one of a series of instructional images, used by the Minnesota Board of Health, in order to train its state public health workers. The focus of these images was on protecting water supplies from bacterial contamination due to incorrect disposal of waste, which might foul ground water, rivers, lakes, and streams.
