   CHEMICAL OXYGEN DEMAND OR (COD) OF SEWAGE, SEWAGE EFFLUENT, POLLUTED WATERS OR INDUSTRIAL WASTES. Is a measure of the oxygen equivalent of that portion of the organic matter in a sample that is susceptible to oxidation by a strong chemical oxidant. The laboratory determination shall be made in accordance with procedures set forth in Standard Methods.
