Testers of COD Effluents Sought for Interlaboratory Study

An interlaboratory study is being coordinated to determine the quality assurance, quality control, and precision and bias sections of a new standard being developed, “Standard Test Method for the Determination of Chemical Oxygen Demand (Manganese III Oxygen Demand) For Water.”

These activities are being conducted by a task force of ASTM Subcommittee D19.06 on Methods for Analysis for Organic Substances in Water, operating within Committee D19 on Water. Task force chair Tom Haukebo seeks individuals currently testing for COD (chemical oxygen demand) in industrial or municipal effluents.

The existing standard test requires mercury and other hazardous materials that will not be required in the proposed method, designed to minimize hazardous re-agents.

Contact: Tom Haukebo, Hach Company, 5600 Lindbergh Dr., Loveland, CO 80539 (970/669-3050, x. 2617). Committee D19 meets June 24-28 in Tucson, Ariz. For meeting or membership information, contact manager Bruce Noe, ASTM (610/832-9719). //
