TM97-12 Implementation of Method-O-7100-96 Determination of Nonpurgeable Suspended Organic Carbon by Wet-chemical Oxidation and Infrared Spectrometry

The National Water Quality Laboratory (NWQL) analyzes Suspended Organic Carbon (SOC) in water samples by Method O-7100-83 as described in "U.S. Geological Survey Techniques of Water Resources Investigations," Wershaw and others, 1987*. A method review by the NWQL demonstrated that the analysis was averaging 81 percent recovery of the SOC with a standard deviation of 18 percent recovery
