Surface Water Case Study – Athabasca Watershed
Surface water samples in the Athabasca watershed are regularly monitored to ensure water safety across the watershed. In this study, chemical oxygen demand (COD) was monitored to evaluate organic matter and to enhance current monitoring programs. Over an eight-month period, MANTECH worked with Environment Canada’s National Laboratory of Environmental Testing (NLET) to study a new automated innovation, the PeCOD® Analyzer, developed by MANTECH. This COD method utilizes a new technology, peCOD, which is a photoelectrochemical technique that directly measures dissolved COD in a sample in approximately ten minutes, without the need for any hazardous chemicals. Results obtained by the automated PeCOD® Analyzer system demonstrate that the COD measured using the peCOD method validated a strong correlation to the COD measurement obtained by the traditional dichromate method.
