Biochemical oxygen demand measures the amount of oxygen required by aerobic bacteria to break down organic matter in wastewaters, providing an index of the level of organic pollution in the water. Knowledge of the characteristics of a site is essential for proper sample preparation to obtain accurate results. While BOD has been adopted as the standard for measuring organic pollution levels, it has a long turn-around time of five days and there are other more rapid analyses available to assess organic pollution, such as total organic carbon (TOC) concentration and chemical oxygen demand (COD). This presentation provides an overview of the BOD method and the challenges and considerations encountered in the laboratory, as well as a discussion of the relationships between BOD, TOC, and COD observed at the San Jose-Santa Clara Regional Wastewater Facility.
