Historically, we have relied upon one or more different tests for characterizing dimensions of oxygen demand. These tests include BOD, COD and TOC; the challenges of these tests include the elapsed time to determine the result, the technician time for oversight/laboratory activities, and the challenges with the chemicals utilized. However, the needs for timely results in relation to oxygen demand are intensifying. An improved ability to rapidly characterize the oxygen demand would greatlly facilitate many water quality assessments. As examples, the ability to rapidly characterize oxygen demand would assist both analytical laboratory experiments through identification of the dilution requirements for BOD analyses, as well as provide more timely information related to energy needs for aeration equipment. Of interest in this research is to evaluate the capabilities of the newly-developed PeCOD instrumentation, most notably the opportunity to provide more rapid results with less personnel time, and relying upon green chemistry. The PeCOD capabilities all argue that the robustness of the PeCOD technology may provide very important insights to a range of water quality issues.
