This historic 1919 diagram, which had been digitally enhanced, depicted a cross-sectional representation of a properly constructed flowing well that was being used as a farm’s potable water supply. The pipe was sunk far into the ground allowing for maximum natural filtration offered by the surrounding rocks, sand, and gravel. The end of the pipe was protected against damage, while any water overflow was directed through a drain away from the water source. The receptacle used for capturing the water never touched the sources, thereby, reducing the chances for contamination. This drawing was used by the Minnesota Board of Health to train its public health workers. The focus of this image, was on protecting potable water supplies from bacterial contamination. The specific citation was, “Minnesota State Board of Health, Water Supplies and Sewerage Systems for Farm Residences, July, 1919, p. 25”.
