Description: Caption:
This historic 1928 diagram, which had been digitally enhanced, depicted examples of common pump and well defects, including well covers level with, or below ground surface, inadequate drainage around the top of the pump, or well, cracked tiles, or concrete located around the casing, and a casing top that was level with the bottom of the pit. These defects would prevent proper runoff, directed away from the water supply. 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. The focus of these images was on protecting water supplies from bacterial contamination due to incorrect disposal of waste, which might foul ground water, rivers, lakes, and streams.
