This historic 1938 diagram, which had been digitally enhanced, depicted the minimum allowable distances that should exist between a potable water supply, and sources of possible contamination. The purpose of these images, and the accompanying training, was focused on protecting water supplies from bacterial contamination, due to incorrect disposal of waste, in order to prevent water-borne diseases. The descriptive information accompanying this drawing referred to a governmental publication, which contained instructions describing how to correctly place, and build such a device. The specific citation was, “American Public Health Association Committee on Hygiene of Housing, Water Supply and Sewage Disposal for an Isolated Dwelling , H.A. Whittaker, September, 1938”. This was one of a series of instructional images used by the Minnesota Board of Health, in order to train state public health workers.
