Chlorination

Darnall's chlorinator was not meant to be used in the field. On page 789 of Darnall's 1911 article he stated: “The process is believed to be applicable for use in purifying water supplies for cities, towns, factories, hospitals, etc.” Darnall CR (November 1911). "The purification of water by anhydrous chlorine". Am J Public Health 1 (11): 783–97.

In a 1917 military manual on hygiene it was stated explicitly: “It is not applicable, however, to the needs of troops in the field.” Havard, Valery. Manual of Military Hygiene for the Military Services of the United States. New York:William Wood and Co. 1917, p. 285.

While Darnall stated in his 1911 paper that he believed that he was the first to demonstrate the use of anhydrous chlorine gas, he was not. In Baker's famous history of water purification, he stated: “Liquid chlorine was…used experimentally in 1910 for water disinfection by Major C.R. Darnall, U.S.A. Medical Corps, at Fort Meyer, Va. Seven years earlier Lieutenant Nesfield, of the Indian Army Medical service, reported the result of numerous experiments on the destruction of pathogenic organisms by chlorine [gas] and proposed its application to military use. ‘This’ says Race (36), ‘was the first suggestion of the possibilities of compressed chlorine gas in steel cylinders.’” Baker, Moses N. The Quest for Pure Water: the History of Water Purification from the Earliest Records to the Twentieth Century. 2nd Edition. Vol. 1. Denver: American Water Works Association, 1981, p. 341.

Two original references to Lieutenant Nesfield's discoveries are: Nesfield, V.B. “A Chemical Method of Sterilizing Water Without Affecting its Potability.” Public Health. 15 (July 1903): 601-3.

Nesfield, V.B. “A Simple Chemical Process of Sterilizing Water for Drinking Purposes for Use in the Field and at Home.” The Journal of Preventive Medicine. 8 (1905): 623-32.
