This historic 1922 drawing, which had been digitally enhanced, depicted an improperly constructed municipal drilled well. An obvious hazard was the location of the privy to the left of the station, which was shown draining downhill toward the pump house. It also revealed a dangerous arrangement of the airlift type of pumping equipment, which had been located in a pit that drained overflow to a sewer. However, with this configuration, there was the potential for contamination, should the sewer ever back up, due to flooding. The descriptive information accompanying this drawing referred to a governmental publication, which dealt with this topic, cited as, “Minnesota State Board of Health, Division of Sanitation,
Water Supplies and Sewerage Systems for Municipalities
, March 1923, p. 17”. 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.
