Description: Caption:
This historic 1942 diagram, which had been digitally enhanced and colorized, illustrated a cut-away view of a school building revealing common plumbing defects, which could contribute to the contamination of the school’s potable water supply. This was one of a series of instructional drawings, used by the Minnesota Board of Health to train its state public health workers. 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.
