|Description:||This historic 1921 diagrammatic sketch, which had been digitally enhanced and colorized, depicted the Mankato, Minnesota municipal well, and its connections to sewers and the Minnesota River. River flooding contributed to a water-borne typhoid fever epidemic in June, 1908.|
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 purpose of these images and the training was focused on protecting water supplies from bacterial contamination due to incorrect disposal of waste, such as sewage, which might foul ground water, rivers, lakes, and streams. The descriptive information accompanying this drawing referred to a governmental publication with instructions describing the correct placement and construction of a detached home privy. The specific citation was, “Bracken, H.M., Bass, F. H., Whittaker, H.A. and Hill, H.W., The Mankato Typhoid Fever Epidemic of 1908, Journal of Infectious Diseases, 9:410-74, 1911”.
