Abstract: In stream water quality surveys and in operational studies of sewage treatment plants, long-term biochemical oxygen demand (BOD) tests are often conducted. The purpose of these tests is to find the ultimate oxygen demand of waste and the first-order rate coefficient for the BOD reaction. This information is mandatory if a water quality model is to be used. This paper presents a technique for finding the least squares estimated for the ultimate BOD and rate coefficient without resorting to complicated computer algorithms or subjective graphical methods.
