Chemical Oxygen Demand (COD) is a measure of the amount of organic matter
in water which is susceptible to oxidation by chemical oxidants. COD can be
empirically related to the Biological Oxygen Demand (BOD) and organic carbon
content of a specifi c source of water. This correlation must be determined
experimentally for each source of water.
