Standard methods for the Examination of Water, Sewage, and Industrial Wastes

The first edition of Standard Methods of Water Analysis was published in 1905, just fifty years ago. Since few workers in the sanitary field are familiar with the background of this document, and of its subsequent development, a brief historical review will be of value. A movement for `securing the adoption of more uniform and efficient methods of water analysis` led to the organization of a committee of the Chemical Section of the American Association for the Advancement of Science, and to the publication in 1889 of a report titled: A Method, in Part, for the Sanitary Examination of Water, and for the Statement of Results, Offered for General Adoption.1 This report was divided into five topics: 1. `Free` and `Albuminoid` Ammonia: 2. Oxygen-Consuming Capacity: 3. Total Nitrogen as Nitrates and Nitrites: 4. Nitrogen as Nitrites: and 5. The Statement of Results.
