This historic diagram, which had been digitally enhanced and colorized, depicted a 1910 portable emergency hypochlorite water purification device, used by the Minnesota State Board of Health, Division of Sanitation. This was one of a series of instructional drawings used by the Minnesota Board of Health to train the state's public health workers. The purpose of this, and other like images, and the training, was focused on protecting water supplies from bacterial contamination. The descriptive information accompanying this drawing referred to a governmental publication with instructions describing the correct placement and build-out of such a system. The specific citation was, “Whittaker, H.A.,
Hypochlorite Treatment of Water Supplies; Portable Plant and Field Equipment for its Administration
, Public Health Reports, 30:608-18, 1915”.
