Chicago Medical Recorder, December 1893, Water System Maps
The Chicago Medical Recorder took up the question of water and disease in Chicago in their December 1893 issue. Included were maps showing the opening of the four-mile water intake tunnel between 1892 and 1893, which brought in drinking water from far further out in the lake than before. This was linked to a drop in the number of typhoid cases reported in Chicago in comparison to other large cities like New York, Philadelphia, and Boston.
