Biochemical Oxygen Demand
Method Abstract #124
Scope and Application
This method conforms to Standard Methods 5210 B 23rd Edition, ISO 5815-1 (and 1899-1, -2), ASTM D888, and EPA 405.1. Biochemical oxygen demand (BOD) measures the equivalent amount of oxygen required to biologically oxidize organic compounds in water. It is a key test for determining overall water quality.
BOD involves the measurement of the dissolved oxygen of a sample both immediately after it is obtained (initial DO) and after a period of five days (final DO). The amount of oxygen depleted by microorganisms during the five-day incubation period is used to calculate the BOD of the sample
*The detection limits are subject to the pre-dilution factor of the sample. The MANTECH system meets and exceeds Standard Method requirements for the MDLs.
