More than thirty years ago Proskauer reported the presence of manganese in many ground waters. For a long time afterward little attention was paid to the subject because it had not been proved that manganese imparted any bad qualities to water. But in 1906, the sudden appearance of iron and manganese in the Breslau water supply (1) in such quantities as to cause it to be abandoned, forced the recognition of the fact that iron and manganese produce like qualities in water. The first water in this country in which manganese occurred in sufficient quantity to cause trouble was from a well supplying a New England mill in 1898. The supply was abandoned. However water supplies containing manganese were regarded as uncommon in the United States previous to 1911, when the attention of the Illinois State Water Survey was called to a serious incrustation which had formed in the city water system of Mount Vernon, Illinois. (2) An analysis showed this to contain 4.4 to 8.8% and the original water to contain 0.6 ppm. manganese. Even at the present time manganese is seldom considered in the selection of a supply.
