A deposit containing manganese, found in a water pipe at the State University of Iowa led Bartow and Bailey to investigate waters of Iowa City, and to adapt the periodate method for manganese in iron, to the determination of manganese in water. Manganese in quantities above 0.1 p.p.m. is objectionable in a water supply. It deposits in the cold water pipes as a dark brown gummy sludge of the hydrous oxides, which is often so extensive as to cause complete stoppage. Manganese also incrusts the sand of filter beds, causing caking and poor backwashing of filters. Manganese stains plumbing and discolors goods in the laundry.
